General operating conditions:
• Ambient temperature ............................. : -15 °C to +50 °C
• Humidity................................................. : max. 80% relative humidity
• Protection class ..................................... : IP 65
• Electromagnetic compatibility................ : Immunity, industrial area
We recommend to equip GIS chain hoists working outdoors with a shelter to protect against the weather. Special operating conditions can
be agreed in individual cases with the manufacturer. After consultation, appropriate, optimised equipment, and important information for
safe, low-wear use can be supplied. The intended use of the electric chain hoist likewise assumes the adherence to the operating, mainte-
nance and servicing prescribed by the manufacturer.
Ensure that only one type of electric chain hoist from the same manufacturer with the same lifting speed is used to lift each assembly.
Electric chain hoists with different lifting capacities/speeds should not be used for the same manipulation. Note that electric chain hoists
with different lifting capacities can run at different speeds even if the same lifting speed is cited on the type plate.
The electric chain hoists in the LP series are designed for provision and use at events. Events include concerts, shows, events, conven-
tions, conferences, exhibitions, presentations, demonstrations, cinema or television recordings and the like. Venues include theatres,
multi-purpose halls, studios, production facilities for film, television and radio, concert halls, convention centres, schools, exhibitions, trade
fairs, museums, discos, variety shows, theme parks, sports facilities, open air theatres and open-air events.
The IGVW (entertainment technology industry association) differentiates between three types of electric chain hoists:
D8 electric chain hoist
In the context of this quality standard, a D8 electric chain hoist complies with the requirements stipulated in DIN EN 14492-2 and shall not
be used for holding or moving loads above people without employing additional protective measures.
The electric chain hoists of the LP types are lifting equipment for various loads. They can be installed as stationary or mobile units, while
a lateral oscillation must be ensured. The electric chain hoists are manufactured in accordance with the latest technical developments and
recognised safety standards, and are tested for safe operation by the manufacturer. Electric chain hoists are approved by various interna-
tional classification societies such as TÜV and others. Electric chain hoists of the above types may only be used when in an acceptable
technical condition, in accordance with their intended use, by trained personnel in a safe and responsible manner.
0.6 Appropriate use
0.5.2 Warranty
The warranty is void if the installation, operation, testing and maintenance is not carried in accordance with this instruction manual. Re-
pairs and troubleshooting under warranty may only be carried out by qualified persons after consultation and agreement with the manufac-
turer/supplier. Any modifications to the product or the use of non-original spare parts will void the warranty.
0.5.1 Periodic checks
Each device/unit operator should adequately note all checks, maintenance and inspections performed in the inspection pass, and have
these confirmed by the competent person in charge. Incorrect or missing entries will lead to forfeiture of the manufacturer's warranty.
The devices are to be checked periodically by a specialist. Primarily, visual and functional checks are to be carried out, whe-
reby the state of components with respect to damage, wear, corrosion or any other changes is determined. In addition, safety
equipment is assessed for completeness and efficiency. It may be necessary to dismantle the equipment to correctly assess
wear parts.
Load-bearing parts must be inspected over their entire length, including covered or hidden parts.
All periodical inspections should be arranged by the operator.

9Swiss Lifting Solutions
Excessive inching operations, slack chains and driving against the limit stops should be avoided. The loads shall be lifted
off the ground with the lowest available lifting speed (per EN 14492). If these instructions are not followed, the manufacturer
accepts no liability for damage to equipment and third parties caused by such actions.
Figure 0-6
The LPML/LPL types of the electric chain hoists are manufactured only as D8 versions. They can be operated both individually and in
groups.
Improper use comprises:
• exceeding the defined maximum permissible load capacity
• pulling the load diagonally (maximum angle 4°, see figure 0-6)
• heaving, pulling or dragging the load
• transporting persons
• transporting excessive loads
• pulling on the control cable
• failing to observe the load hook constantly
• running the chain over edges
• failing to observe the load constantly

Table 0-2 Operating conditions
D8 PLUS electric chain hoist
In the context of this quality standard, a D8 PLUS electric chain hoist has been designed, dimensioned and equipped such that it can be
used for holding loads above people.
C1 electric chain hoist
In the context of this quality standard, a C1 electric chain hoist complies with the requirements stipulated in DIN 56950-1 and can in prin-
ciple be used for holding or moving loads above people.
Electric chain hoists are offered in a variety of types and equipment variants and with different safety devices. Therefore, the choice of the
chain hoist is of considerable importance. Here, the hazards resulting from the type of use are to be used as a basis whilst also taking the
specific conditions of use into account. The selection of the type of the electric chain hoist is dependent on the operating conditions.

10 Swiss Lifting Solutions
The manufacturer will only guarantee the safety and lasting operation of the electric chain hoist when used for applications in accordance
with valid standard values that fall within its classification.
Before the initial start-up, the user must estimate according to the parameters in table 1-1, which of the four types of load is applicable to
the use of the electric chain hoist during its whole life cycle. The table 1-2 shows standard values for the operating conditions of the classi-
fications depending on the type of load and time of operation.
Classification according to application requirements:
Electric chain hoists and trolleys are categorised in accordance with the following regulations into classifications:
• DIN EN 14492-2 (A5 = 125,000 cycles)
• ISO 4301-1 (M5 = 1 600 h)
• DIN 15401 / DIN EN 13001 (load hook)
• Remarks about general overhaul (see chapter 4)
There is different coefficient data for the classifications that must be adhered to in operation.
The travel trolley must have at least the same lifting capacity as the electric chain hoist.
The classification of the electric chain hoist can be found on the data plate.

Example 1: Calculate permissible operating time of the electric chain hoist
An electric chain hoist of the classification A4 is to be used for medium stress load tasks throughout its whole calculated service life.
This corresponds to the type of load "Q4 heavy" (see table 1-1). Corresponding to the values in table 1-2, the electric chain hoist should
not be used for more than 60 cycles per day.
Example 2: Calculate the permissible type of load
An electric chain hoist of the classification A5 is to be used for approximately 400 cycles per working day, throughout its whole service life.
Thus, the electric chain hoist must be operated in accordance with the characteristics of the type of load 'Q2 light' (see table 1-1).
Ascertaining the correct type of application for an electric chain hoist:
Either the operating time or expected type of load can be used as a basis for ascertaining the correct type of application for the electric
chain hoist.
Before initial start-up of the electric chain hoist, it is necessary to ascertain which of the load types in table 1-1 applies to the
operation of the electric chain hoist. Assignment to a load type or a load spectrum (Q) applies for the whole service life of the
equipment and may not be altered for operational safety reasons.

The electric chain hoist meets the requirements of the EC Machinery Directive and the harmonized EN standards. Housing and cover of
the electric chain hoist are made of a sturdy die-cast aluminium. Cooling fins on the attached motor ensure optimum cooling. The chain
container can be attached to the compactly constructed housing. A drilled hole is provided for the power supply cable gland and for the
cable gland for the control cable. The eyebolt suspension or optional hook suspension are attached on the housing. The electric chain
hoists of the LP series are suitable for use as a climbing hoist. Two carrying handles (figure 1-2) facilitate the transport of the chain hoists.
GIS electric chain hoists are driven by asynchronous motors. The braking system consists of one (D8) or two (D8 PLUS, C1) DC-operated
magnetic brakes. When there is no current, pressure springs generate the braking torque.
The slipping clutch is installed in front of of the braking system due to its function. It protects the chain hoist from overload and takes on the
function of an emergency stop for the highest and lowest hook positions. The electric chain hoists of the LP series are suitable for direct
control.
The high tensile profile steel chain corresponds to grade DAT (8SS) per DIN EN 818-7. The chain wheel is hardened. The load hook, which
complies with DIN 15401 / DIN EN 13001, is fitted with a safety catch. The 3-stage enclosed spur gears are generally helical. The gears
are mounted on roller bearings and run with grease lubrication.

The safety directions for handling with loads should be followed (see chapter 0.3) when transporting and assembling the electric chain
hoist. Electric chain hoists must be assembled by qualified staff, always bearing in mind the accident prevention directions in chapter 0.2.
Before assembly, the electric chain hoist must be stored in an closed room or covered area. Should the electric chain hoist be destined for
operation outdoors, then it is recommended that a protective cover is erected to shield it from the effects of the weather.
2.1 Transport and assembly
Mechanical adjustments may only be performed by authorised specialists.
Operating staff must carefully read the instruction manual of the electric chain hoist before initial start-up and carry out all the
checks. The device shall be put back into operation only after operational safety has been established. Unauthorised persons
may not operate the device or carry out work with it.
The operator must create an inspection pass during the commissioning of the electric chain hoist. The inspection pass con-
tains all the technical data and the date of commissioning. It provides a record of all servicing and maintenance work.

• Before connecting the electric chain hoist, check whether the operating voltage and frequency specified on the type plate correspond to
the available power supply.
• Remove the cover from the control unit box.
Connection with direct control:
• Introduce the connection cable with cable gland M25 × 1.5 through the lower hole and connect in accordance with the attached
electrical chart to L1, L2, L3 and PE (see figure 2-1).
• With direct operated chain hoists without PMS relay contact is provided for connection of the brake. The brake must be switched on the
direct current side.
Connection with contactor control:
• Introduce the connection cable with cable gland M25 × 1.5 through the lower hole and connect in accordance with the attached
electrical chart to L1, L2, L3 and PE (see figure 2-2).
• Introduce the control cable through cable gland M20 × 1.5 in the hole below the housing and connect to terminals 1, 2, 3, 4, 10
(see figure 2-3).
When using a control switch:
• Strain relief to housing (see figure 2-4).
• Re-fit the cover from the control unit box.
• To maintain the predetermined protection class IP 65, all cables must fit into the corresponding cable glands and the cover
screws must be tightened after the connection with the torque specified in table 3.2.9.
• The control switch must be attached to the strain relief cord and not to the cable.
The protective conductor should not conduct any current during operation. With the installation of a motor protection breaker,
the current of the electric chain hoist must be observed in accordance with the type plate.
2.2.1 Electrical connections
Electrical installations may only be performed by authorised specialists.
The mains connection cable, the mains connection fuse and the main switch for connecting the electric chain hoist to the mains power
supply must be provided by the customer. A 4-wire cable with a PE protective conductor is needed as a supply line for three-phase versi-
ons. A 3-wire cable with a protective conductor is adequate for single-phase version. The length and cross-section must be appropriate for
the power consumption of the electric chain hoist. The wiring diagram is located in the lid of the electric chain hoist. In D8 PLUS electric
chain hoists, the power supply must be interrupted by means of a lockable switch, after reaching the desired position.
The control system must be fitted with an emergency stop button for monitoring. The power supply should be disconnected if the electric
chain hoist is not in use. Only experienced and competent users may operate lifting systems or individual electric chain hoists.
The principles per BGG 912/GUV-G 912 are to be applied. An inspection pass is to be created consisting of the installation documentation
from the manufacturer and the test records. Plans and descriptions for electrical installation are to be supplemented by the corresponding
control system constructor on a project-specific basis.inspection pass is to be created consisting of the installation documentation from the
manufacturer and the test records. Plans and descriptions for electrical installation are to be supplemented by the corresponding control

2.2.2 Brake system
The brake must be able to hold the nominal load in power free mode without any problems. For chain hoists with two brakes, the functio-
nality of the two brakes must be checked during the system acceptance test. The first brake is on the DC side, the second brake on the AC
side and thereby switches with a slight delay.
The functional testing of the brake system is carried out under nominal load:
First brake:
Release the mounting screws of the second brake. The rotor of this brake now rotates freely. The function of the second brake is discon-
nected. Raise and lower: The first brake must be capable of braking and hold the nominal load. Tighten the mounting screws again after
the function test.
Second brake:
Electrical Method:
The first brake is released from + and - terminals and activated by a non-controlled current source (directly from L1 and L2). To activate a
rectifier must be switched between. Thus, the first brake is disconnected and the second brake can be tested by lifting and lowering the
load. Lifting and lowering with unloaded first brake: The second brake must be capable of braking and hold the nominal load. After the
function test reconnect the first brake to the terminals + and -.
Mechanical method:
With a tool, the pressure ring of the first brake is pressed to the solenoid, so that the rotor of the brake can rotate freely. The function of
the first brake is disconnected. Lifting and lowering with unloaded first brake: The second brake must be capable of braking and hold the
nominal load.

• Checking direction of rotation: If the directions of movement do not match the button symbols of the control switch,
the supply line wires L1 and L2 must be transposed.
• In the single-phase version, inching operations can cause malfunctions.
Open the terminal used in accordance with figure 2-5.

Chain end:
The chain end is to be fixed to the housing in accordance with figure 2-7 or figure 2-8 and the limit stop in accordance with figure 2-9.
Ensure that the end of the chain is not twisted. The section of chain after the limit stop (1) must be adjusted to the height of the chain
container. Here, the length of the chain section must be selected such that the limit stop lies on the floor of the container when the chain is
pulled into it (see figure 2-10).
1 fall operation:
The load hook (1) is connected to the chain with a single fall hook clamp (2). For the power transmission, the mounting of the bolt (3) is
important (see figure 2-11).
• Note correct arrangement of suspension (mass k1, see figure 2-12 or for LP 2500, see figure 2-13):
LPM/LPML 250 = symmetrical, LP/LPL 500 = 41 mm, LP 1000 = 43 mm, LP 1600 = 53 mm, LP 2500 = 87 mm.
• Grease the bearings thoroughly (load hook).
Figure 2-6
2.2.3 Load chain
• Only use original chains.
• Welding seam of the chain links must face inward on the chain wheel (see figure 2-6).
• When used as a climbing hoist, make sure that the entry and the run-out of the chain is not prevented
by chain clusters.
• The geared limit switch must be mechanically deactivated for pulling in the chain, see chapter 2.2.4.
Before start-up and during operation, the load chain must be oiled along its full length. Oil must constantly be present on the internal, con-
tacting and rubbing surfaces of the chain links. Lubrication is carried out by submersion or with an oil can, using a creeping gear oil. The
end of the chain (1) should be attached to a flexible piece of wire or chain pulling loop (2) and fed through the chain wheel (3) of the electric
chain hoist. Through short switching impulses, the chain will be pulled in correctly in accordance with figure 2-6. The lifting height must be
adjusted such that the hook fittings lie on the ground in the lowest hook position.

Double fall operation (only available with the LP 2500 model):
Fit load hook (1) with double fall hook clamp (2) in accordance with figure 2-14. Connect load-side chain end with the chain holder (3) and
fasten into the guide rail of the housing. Secure the chain holder with screw (4) and spring washer (5).
• Note correct arrangement of suspension (mass k2, see figure 2-15):
LP 2500 = 130 mm.
• No longitudinal twisting of the chain (see figure 2-16).
• Grease the bearings thoroughly (deflection roller / load hook).

Adjustment description (see gure 2-17):
• Provision only with model LPM/LPML 250: Loosen screws (1 + 2) and turn clamping strip (3) away (see figure 2-18).
• The geared limit switch must be deactivated mechanically by pressing the rocker switch (1) before drawing the chain in or when
changing the chain.
• Draw the chain in.
• Move to the highest hook position and turn the red switch wheel (2, rear) until it reaches the switch cam on the top limit switch (3)
(turn clockwise for the lowest hook position and anticlockwise for higher hook positions).
• Activate the rocker switch (1) (the rocker switch must latch into the switch wheel).
• Move to the lowest hook position, press the rocker switch (1) and turn the green switch wheel (4, front) until it reaches the switch cam
on the bottom limit switch (5) (turn clockwise for the lowest hook position and anticlockwise for higher hook positions).
• Activate the rocker switch (1) (the rocker switch must latch into the switch wheel).
• Check the limit switch function: the limit stop and the bottom hook block may not touch the housing.
• Check emergency limit switch: if the downstream emergency limit switch (6) is triggered, the control voltage phase is
interrupted. A further lifting movement is therefore only possible if the emergency limit switch is bridged.

2.2.4 Limit switch
In direct-controlled electric chain hoists no limit switch is installed. It is important to ensure that is not driven against the
housing during operation. The geared limit switch of the contactor controlled electric chain hoist is only allowed for control
voltage up to 230 V AC.
In electric chain hoists with contactor control, a geared limit switch is built in as standard. This is also suitable as a regular limit stop with
high switching precision. The limit switch function (highest and lowest hook position) must be tested during start-up. Four different trans-
missions are available depending on the lifting height:

2.2.5 Chain container
• Textile chain containers are suitable for vertically mounted electric chain hoists and for climbing hoists.
• Attach the free end of chain to housing (see chapter 2.2.3).
• Fit the chain container and allow the chain to run in: Vertically mounted chain hoists (LPM/LPML 250 see figure 2-19,
LP/LPL 500 see figure 2-20, LP 1000 see figure 2-21, LP 1600/2500 see figure 2-22) or climbing hoists (LPM/LPML 250 see figure 2-23,
LP/LPL 500 see figure 2-24, LP 1000 see figure 2-25, LP 1600/2500 see figure 2-26).
Chain container must hang freely. Badly lubricated chains will occupy more volume in a chain container. We recommend filling
to a maximum of 50% to 70%. With climbing hoists, ensure that the chain runs over the curvature of the chain holder.

General:
Care and maintenance tasks are preventive measures designed to preserve the full functionality of electric chain hoists. Non-compliance
with care and maintenance routines can result in limited use and damage to electric chain hoists.
Care and maintenance should be carried out in accordance with the instruction manual at predefined time intervals (table 3-1 and 3-2).
During care and maintenance work, general accident prevention directions, special safety directions (chapter 0.3) as well as hazard pro-
tection instructions (chapter 0.4) should be followed.
Care and maintenance work should be performed only on electric chain hoists with no loads. The main switch must be off.
The hook fittings must lie on the ground or on the maintenance platform.
Care work encompasses visual checks and cleaning routines. Maintenance work includes additional functional checks. During the functio-
nal checks, all fixing elements and cable clamps must be checked for tightness. Cables must be inspected for dirt, discolouration and arc
spots.
Used operating materials (oil, grease, etc.) should be safely collected and disposed of in an environmentally friendly manner.
Operating failures in electric chain hoists affecting the safe operation of the device should be remedied immediately.
Maintenance and repair work on the electric chain hoist may only be carried out by qualified and trained personnel.
If the operator performs maintenance work on an electric chain hoist on their own, the type of maintenance performed together
with the date carried out must be entered in the inspection pass.
Alternations, as well as modifications and additions to electric chain hoists, which may affect safety, must be authorised by the manufacturer
in advance. Structural alterations to chain hoists not authorised by the manufacturer exempt the manufacturer from liability in the event of
damage. Material warranty claims will only be recognised as valid if original manufacturer's spare parts are used exclusively. We explicitly
advise that original parts and accessories not delivered by us are also not checked or approved by us.
