General:
The GCH series consist of the following models:
GCH, GCHK, GCHS, GCHHK, GCHHTD, GCHR
Classification according to application requirements:
Electric chain hoists and travelling gears are classified according to the following
regulations into ISO Groups:
DIN EN 14492-2
DIN 15400 (load hook)
FEM calculation regulations for series lifting equipment
(chain drive, motor, full load-life span)
ISO 4301-1: D (M3) = 400 h
Remarks about general revision (see chapter 4)
There is differing coefficient data for the ISO Groups that must be adhered to in
operation.
CAUTION !
The travelling gear is always classified as the same ISO Group as the
corresponding electric chain hoist.
NOTE
The ISO Group registration number of the electric chain hoist can be found
on the data plate.
The manufacturer will only guarantee the safety and lasting operation of the electric
chain hoist when used for applications that fall within its valid ISO Group coefficient
data.
Before the first start-up, the user must estimate according to the features in table 1-1,
which of the four types of load is applicable to the use of the electric chain hoist during
its whole service life. Table 1-2 shows standard values for the operating conditions of
the ISO Groups depending on the type of load and the time of operation.
Ascertaining the correct type of application for an electric chain hoist:
Either the running time or expected type of load can be used as a basis for ascertaining
the correct type of application for the electric chain hoist.
CAUTION !
Before starting up the electric chain hoist for the first time, it must be
determined with which of the load types shown in table 1-1 the electric chain
hoist is to operate. Assignment to a load type or a load collective (k) applies
for the entire operational life of the equipment and may not be altered for
operational safety reasons.
Example 1: Ascertaining permissible running time of the electric chain hoist:
An electric chain hoist of the ISO Group M4 is to be used for medium stress load tasks
throughout its entire service life. This corresponds to load type <3 heavy> (see table
1-1). According to the values in table 1-2, the electric chain hoist should not be used for
longer than 0.5 - 1 hour per working day.

GIS CHAIN HOIST SWISS QUALITY 9
Example 2: Ascertaining permissible load type:
An electric chain hoist of the ISO Group M5 is to be used for approximately 6 hours per
working day, throughout its complete service life. Consequently the electric chain hoist
should be operated in accordance with the characteristics of the load type <1 light> (see
table 1-1).

The electric chain hoist meets the requirements of the EC Machinery Directive and the
relevant EN and FEM standards.
Housing and cover are made of a sturdy aluminum die casting. Fins on the motor
ensure optimum cooling. The chain box can be attached to the compactly constructed
housing. A drilled hole is provided for both the power supply cable gland and the control
cable. The lugs, or optionally the suspension hooks, are attached to the flange ring.
GIS electric chain hoists are driven by asynchronous motors. For two-speed models a
pole switching version of the motor is fitted.
The braking system consists of a DC-operated spring loaded brake. When there is no
current, the pressure spring generates the braking torque.
For functional reasons, the slip clutch is installed in front of the brake system and
integrated into the rotor shaft. It protects the hoist from overload and takes on the
function of an emergency end stop for the highest and lowest hook positions.
A gear-type limit switch is fitted to limit the highest and lowest hook position. As an
option, emergency stop contacts with positive separation can be retrofitted downstream.
Electric chain hoists are fitted with a 42 V contactor control as standard. The emergency
stop contactor that is usually installed separates all three mains power phases when the
red button is pressed.
The high-strength round steel chain meets the requirements of grade DAT (8SS) to DIN
EN 818-7. Sprocket and pulley are hardened. The load hook, which complies with DIN
15400, is fitted with a safety latch.
The two-or three-stage, closed spur gear units are usually helically cut. The gears are
mounted on roller bearings and run greased.
The standard equipment fitted to the electric chain hoist includes a control switch (up/
down with emergency stop).

3 Service and maintenance
3.1 General regulations for service
and maintenance work
Operating failures in electric chain hoists affecting the safe operation of the device
should be remedied immediately.
CAUTION !
Maintenance and repair work on the electric chain hoist may only be carried
out by qualified and trained personnel.
CAUTION !
If the operator performs maintenance work on an electric chain hoist on his
own account, the type of maintenance performed together with the date
carried out must be entered in the log book.
Alterations to, as well as modifications and supplements to electric chain hoists which
may affect safety must be authorized by the manufacturer in advance. Structural
alterations to chain hoists not authorized by the manufacturer exempt the manufacturer
from liability in case of damage.
Material warranty claims will only be recognized if solely manufacturer’s genuine spare
parts have been used.
We explicitly wish to point out that those original parts and accessories not supplied on
our behalf cannot be inspected or released by us.
General:
Service and maintenance are preventive measures designed to preserve the full
functionality of electric chain hoists. Non-compliance with service and maintenance
routines can result in reduction in the useful function of and/ or damage to electric
chain hoists.
Service and maintenance work should be carried out at the predefined time intervals,
in accordance with the instruction manual (table 3-1 and 3-2).

3.2 Service and maintenance
3.2.1 Maintenance overview
During service and maintenance work, general accident prevention directions, special
safety directions (chapter 0.3) as well as hazard protection instructions (chapter 0.4)
should be followed.
DANGER !
Service and maintenance work should only be performed on unloaded
electric chain hoists. The main switch must be off. The lower sheave or
hook fittings must be lying on the floor or a maintenance platform.
Maintenance work encompasses visual checks and cleaning routines. Service work
includes additional functional checks. During the functional checks, all securing
elements and cable clamps must be checked for secure seating.
Cables must be inspected for dirt, discoloration and arc spots.
CAUTION !
Used operating materials (oil, lubricants, etc.) should be safely collected
and disposed of in an environmentally friendly manner.
Service and maintenance intervals are defined as follows:
t ............ : daily
3 M ....... : quarterly
12 M ..... : annually
The predefined service and maintenance intervals should be reduced when the loading
of the electric chain hoist is exceptionally large and when frequently operated in adverse
conditions (dust, heat, humidity, steam, etc.).
See table 3-1.

3.2.3 Brake system
The spring-loaded brake is a solenoid operated single disk brake with two friction
surfaces. The braking force is applied by compression springs. The braking torque is
generated when no current is applied. The ventilation is electromagnetic. The brake
operates with DC current.
The brake must be able to hold the nominal load in power free mode without any
problems.
CAUTION !
The brake coil voltage must be the same as the operating voltage.

GIS CHAIN HOIST SWISS QUALITY 17
NOTE
The brake has no air gap adjustment. If the air gap (a max., table 3-3 and
figure 3-1) reaches maximal value, the brake pad needs changing.

3.2.4 Load chain
The load chain should be periodically checked for abrasion. The check is based upon
three measurements: see accepted wear factors (table 3-4) and measurement points
(figure 3-2).
CAUTION !
The chain should be replaced when the measurements exceed or fall short
of those defined in the table. The chain wheel and chain guide should be
checked for wear at the same time and, where necessary, be replaced. Only
use original chains. The chain links should not be welded.
The new chain is installed in accordance with chapter 2.2.2.
NOTE
For ease of installation, the old chain and new chain can be connected by a
piece of flexible wire.

3.2.8 Suspension parts
3.3 Ordering spare parts
4 Measures for obtaining a
safe period of operation
4.1 Determining the actual
utilization period S
4.2 General overhaul
All statically loaded parts are considered suspension parts. The bearing surfaces of the
slewing suspension parts must be periodically greased.
Torque values for screws of property class 8.8 according to DIN ISO 898:
M 5 M 6 M 8 M 10 M 12
6 Nm 10 Nm 24 Nm 48 Nm 83 Nm
Information on how to order spare parts can be found on page 3.
The statutory and health requirements of the EU regulations stipulate that specific
dangers which may arise from fatigue or ageing must be prevented.
Accordingly, operators of standard hoist gear are obliged to determine the actual
utilization. The actual utilization period is determined and recorded as part of the annual
inspection by customer service engineers. A general overhaul must be carried out when
the theoretical utilization limit is reached, or after no more than 10 years.
All checking and the general overhaul itself must be arranged by the operator of the
hoist gear. The following theoretical utilization periods apply to electric chain hoists that
are categorized according to ISO 4301-1 (converted into full-load hours):
M3 M4 M5 M6 M7
400 h 800 h 1600 h 3200 h 6300 h
The actual utilization period depends on the daily operating time and the load collective.
Running time is determined from information provided by the operator or recorded using
a meter that counts the number of operating hours. The load collective is determined in
accordance with table 1-1, page 9. These two items of information are used to calculate
the annual utilization period from table 4-1.
If an operating data acquisition system (BDE) is used, the actual utilization can be read
out directly by our experts during the annual inspection.
CAUTION !
The values periodically calculated or read-off must be recorded in the log
book.
On reaching the theoretical service life (no later than 10 years for recording without
BDE), a general overhaul should be performed. This enables the equipment to continue
operating safely for a further period of utilization (service life). Components must be
inspected and/ or replaced in this overhaul according to table 4-2. Inspection and
approval for further use must be performed either by a specialist company authorized by
the manufacturer, or by the manufacturer personally.
The inspector determines: – the new theoretical utilization possible
– the maximum period until the next general overhaul
This data should be recorded in the log book.
