1. Important safety information for assembly and operation
• Installation and maintenance of Yale endless winches may only be
carried out by persons who are familiar with this work and have been
assigned to these tasks by the operating company.
• These persons must know the relevant accident prevention regula-
tions, for example “Winches, lifting and towing devices” (BGV D8),
“Cranes – Power driven winches and hoists” (EN14492-1), etc. and
must have received appropriate relevant instructions; furthermore they
must have read and understood the operating and assembly instruc-
tions of the manufacturer.
• Yale endless winches are only intended for transporting material and
exclusively approved for this purpose. Any other applications must be
agreed with the manufacturer and, if applicable, licensing authorities.
• The load capacity indicated on the unit is the maximum working load
limit (rated load) that must not be exceeded.
• The use of Yale endless winches in areas with an explosion hazard
is prohibited.
• Yale endless winches may only be used at ambient temperatures
between -40°C and +70°C.
• Do not lift or transport loads, as long as persons are in the danger
zone of the load.
• Do not allow personnel to stay or pass under a suspended load.
• A lifted or clamped load must not be left unattended or remain lifted
or clamped for a longer period of time.
• The operator may start moving the load only after he has checked
that it has been attached correctly and all persons are clear of the
danger zone.
• When attaching the unit, the operator must ensure that during opera-
tion of the hoist neither the hoist, the supporting equipment nor the
load pose a danger to himself or other personnel.
• Fixed or obstructed loads must not be lifted.
• Loads must not be turned during operation. If it is necessary to turn
loads during operation, anti-twist swivels must be provided and/or the
manufacturer must be consulted.
• Avoid excessive inching operation by frequent, brief actuation of the
control switch.
• For lifting the load from the ground, always use the lowest available
lifting speed. The rope must first be tensioned at this speed; it must
not be slack when the load is lifted from the ground. If the winch has
two speeds, the low speed must only be used for short distances.
• It is forbidden to use the hoist for the transportation of persons.
• Welding work on the hook and the rope is strictly forbidden. The rope
must not be used as earth conductor for welding work.
• Before starting assembly, check all parts for completeness and fault-
less condition.
• Only use perfect Yale endless winches, ropes, electrical cables and
lifting tackle.
• Only use the original Yale wire rope in appropriate condition. Only use
common multi-purpose oil or grease for lubricating the winch and wire
rope. Do not use any lubricants which contain molybdenum disulphide
(MoS2) or PTFE! Using any other wire rope voids all warranty claims
against Yale Industrial Products.
• Yale endless winches and Yale safety lock systems must only be fas-
tened at the fixing bore holes provided for this purpose.
• Yale endless winches must be fastened in such a way that the loaded
suspension rope enters vertically from all directions.
• Overloading Yale endless winches is strictly forbidden.
• Inspections or repairs must only be carried out by Yale Industrial Prod-
ucts or by a hoist service company authorised by the manufacturer.
• The electrical connection of Yale endless winches and of electrical
accessories must be carried out by qualified electricians in accord-
ance with EN60204-1 or -32. Inspections and repairs of the electrical
equipment must only be carried out by qualified electricians or by a
hoist service company authorised by the manufacturer.
• Yale Industrial Products does not accept any liability for damage result-
ing from the use of other than the original parts or caused by conversion
and modification of units supplied by Yale Industrial Products.

2. Description of the winch
2.1 Correct operation
Yale endless winches of the YMT-M series are electrical hoisting equip-
ment for lifting and lowering loads in accordance with EN14492-1 up to
the specified load capacity and by means of Yale wire ropes. The load
capacity indicated on the unit is the maximum working load limit (rated
load) that must not be exceeded.
For trouble-free and safe working with Yale endless winches it is impera-
tive that an original Yale rope be used.
Yale endless winches with an operating speed of 9m/min are classified
in group of mechanisms M3/1Bm, and with 18 m/min in M2/1Cm in
accordance with ISO4301-1 / DIN15020.
2.2 Winch operating mode
On the control system, there is a pushbutton for UP and one for DOWN
travel.
The Yale endless winch does not collect the wire rope but moves it
through the winch at a constant speed. Therefore, the rope length, i.e.
the lifting height, is virtually unlimited.
All Yale endless winches for transporting material can be fitted with an
optional overload switch-off.
If the load capacity of the Yale endless winch is not sufficient in direct
pulling it can be increased based on the pulley principle.
2.3 Original Yale rope
Yale endless winches must only be operated with the original Yale rope:
Marking on the tag as follows:
Front: CMCO + batch number
Rear: Nominal diameter + rope length (for the relevant nominal rope
diameters, see the technical data in section 2.5).

2.4 Yale control systems
Yale endless winches can be provided with different control systems. They
are connected to the mains network by wiring in the control system or by
means of a CEE plug.
The control elements comprise a pushbutton for ‘UP’, one for ‘DOWN’ and
an emergency-stop pushbutton.
A lockable main switch and a change-over switch for simultaneous or sepa-
rate control of two endless winches are available as options. Limit switches
and emergency-limit switches can also be connected to the control system
as options.

2.6 Safety features
The following equipment is available to ensure the safety of Yale units:
A) Emergency stop
By pushing the emergency-stop button, the whole control system is switched
off in event of an emergency. By turning and pulling the button in the direction
indicated by the arrow, it is unlocked again.
B) Motor brake
All Yale endless winches are provided with an electro-magnetically released
spring brake, which closes automatically when the pushbutton for UP/DOWN
travel is released and in the case of a power failure.
C) Manual descent
In the event of a power failure, the brake can be released manually by
means of the lever.
Pull the lever out of the handle of the winch, insert it in the bore hole of the
motor brake and push it upwards.
D) Overload switch-off (optional)
The overload switch-off available as an option switches off UP travel in the
event of an overload. At the same time a warning signal (buzzer) is trig-
gered which only stops, if the cause of overloading has been eliminated.
Possible causes for switch-off:
• the winch is overloaded, e.g. owing to unfavourable load distribution or
• the load has been caught during upwards travel.
After a switch-off, reduce or redistribute the load until overload has been
eliminated or travel downwards until the load is freed from the obstacle; it is
essential to remove the obstacle before restarting.
E) Phase sequence monitoring (optional)
Yale control systems with an integrated phase sequence monitoring feature
prevent the winch from operating in the case of an incorrect phase sequence,
since an incorrect assignment of the UP/DOWN direction buttons may render
limit switches or any fitted overload switch-off features inoperative.
Possible correction: change over two of the phases of the plug or turn the
phase changer in the plug through 180°.
F) Emergency limit switch UP (optional)
For safety reasons, at least one limit or emergency-limit switch should be fitted
at the top for each Yale endless winch which, when triggered, immediately
stops all movements of the load.
For this purpose, a stop plate must be fitted on the suspension rope under
the rope swaging which triggers the limit switch.
Maintain a safety clearance of at least 1.0 m to the winch.
If there are any obstacles protruding into the path of the load, the stop
plate must be lowered so that the winch always stops early enough.
When an emergency-limit switch has been approached, no further electri-
cal movement is possible.
This means that the winch then must be lowered with the manual descent
(see section 2.6 C) until the actuating lever of the emergency-limit switch
is free again.

2.7 Information on remaining risks
Remaining risks exist which cannot be covered by the
design of Yale endless winches:
• Since the optional overload switch-off is normally set to the maximum
load capacity of the winch in the factory, the operating company must
check, if the useful load of the lifting tackle also corresponds to the
value of the overload switch-off and/or to the useful load of the winch.
If this check shows that a lower value is required, the overload switch-off
must be adjusted accordingly, either ex-works or by a trained person
or the specified useful load of the winch must be reduced.
• If no Yale safety lock is fitted on an additional safety rope, a failure of
the winch or a broken rope may result in dropping of the load.
3. Putting the winch into service
3.1 Basic principles
The operating company is responsible for ensuring that the suspension
structure for the winch and the lifting tackle comply with all relevant
regulations.
3.2 Necessary components
• Yale endless winch(es) with appropriate useful load;
• Original Yale rope(s) with an appropriate length
• Connection cable with an appropriate length
• If necessary, rope sheave(s) with an appropriate useful load for return-
ing/reeving the rope (not included in the scope of supply).
3.3 Fixing of the Yale endless winch
A) Mounting material
Yale endless winches of the YMT-M series can either be fixed with two
M10 bolts (for the double-shear connection use two of the four boreholes
dia. D that are not diagonally arranged!), with four M10 bolts (for the
single-shear connection use all four boreholes dia. D) or with one M16
bolt (use borehole dia. C!) and by applying self-locking nuts.
Bolts must be long enough so that they only carry by the barrel and
never by the thread (use spacers if necessary).
The strength class must be at least 8.8. Higher strength classes (10.9
and in particular 12.9) should not be used since these bolts, especially
the galvanized version, tend to become brittle.
Instead of the M10 bolts, studs or similar with at least the same strength
may also be used.
A load bolt with a dia. of 16 mm is included in the scope of supply of
every winch.
B) Fixing of the Yale endless winch
Fix Yale endless winches in such a way that the loaded
suspension rope always enters the winch vertically from
all directions!
We recommend that Yale Industrial Products be contacted for planning the
fastening arrangement of the winch, as required.
In any case the structure for suspending the suspension rope as well as the
component on which the winch is fixed must have at least 2.5 times the
load capacity (lasting deformation not permissible) compared with the useful
load of the winch in order to meet the requirements of standard EN14492-1.

3.4 Yale control systems
A) Contactor control
Access for the mains cable and the control cable is provided on the
contactor control system. Always make sure that the control cable is
provided with a strain relief arrangement.
Important: This control system is only suitable for stationary operation
B) Control system with phase sequence monitoring
A CEE-16A plug is provided on the control system with phase sequence
monitoring for power supply to the endless winch. The control cable is
connected by means of a cable union. Always make sure that the control
cable is provided with a strain relief arrangement.
Motor and, if required, emergency-stop limit switch can be connected
to the control system by means of plug connectors.
C) Control system for two endless winches
A CEE-16A plug is provided on the control system for two endless
winches for power supply to the endless winches. The control elements
for operating the endless winch and the emergency-stop pushbutton are
arranged on the door of the switching cabinet of the control system. The
main switch of the endless winch is also located on the control system.
The two motors and, if required, emergency-stop limit switches can be
connected to the control system by means of plug connectors.
3.5 Power supply
The operating company is responsible for the connection of the Yale endless
winches. It is essential that the circuit diagrams included in the supply be
taken into account.
Complete the electrical connection of the winches in ac-
cordance with EN 60204-1or EN 60204-32. Always pull
the power plug before opening any control system.
1) Always check whether mains voltage and motor voltage match
Three-phase current: 400 V (3P+N+PE), 50 Hz with 16 A CEE plug
2) For min. cross sections of the supply cables, comply with the following
table!

4) Always use heavy rubber cables with strain relief!
5) Always use a cable sleeve or similar, if the drooping cable is longer
than 30 m!
6) If a generator is to be used for power supply, it must have at least 3
times the rated output of the winch motor.
3.6 Fitting the wire ropes
A) Preparation
Caution when handling wire ropes:
Always wear protective gloves.
1) Only use original Yale wire ropes.
Example for the marking of the Yale 8.4 mm rope
(tag on the thimble):
Front Rear
2) Make sure that the wire rope has the correct diameter and an ap-
propriate length.
3) Always unwind the wire rope orderly and without twisting (by also
turning the winder). Otherwise the wire rope may be rendered unus-
able as a consequence of rope slings.

4) Examine the condition of the wire rope:
• Thimble/swaging undamaged?
• For ropes with hook: undamaged safety cover, hooks not bent open?
• Proper rope head, without any obvious damage along the entire length?
Never use the towing rope as an attachment rope and
never wind it around the load! Ensure unrestricted rope
lead-off from the winch! Never pull the rope over edges!
The rope must always be slightly lubricated!
Use common multi-purpose oil or grease for lubricating.
Do not use any lubricants which contain molybdenum
disulphide (MoS2) or PTFE.
Always attach the ropes at the top of the suspension
before letting them run into the winch!
B) Fitting the suspension rope
Insert the head of the wire rope from above as far as possible into the inlet
tube of the Yale endless winch.
• While pushing the UP button, push the rope as long as it winds on by itself
and exits again at the bottom.
Running in the rope with the DOWN button may take
the overload switch-off (optional) out of operation.
If the rope does not run in, check whether the rope head is in order and
whether the UP button has been pushed.
C) Loose end of the rope
• The rope must always be able to run out unhindered! The loose end of
the rope must hang freely to be able to untwist or it must be collected
appropriately and must not form any loops.
• In order to prevent the unloaded wire rope from being damaged, fit a return
sheave or another suitable rope guide, if required!

4. Operation of the winch
4.1 Safety checks before initial operation
(by a competent person)
Prior to initial operation, a competent person must:
• carry out the checks described in sections 4.2 and 4.3,
• perform a trial run of the system with max. useful load and
• actuate the emergency-stop button
=> The load must stop immediately. Turn the emergency-stop button
clockwise for restarting. Travel on and
• check the emergency-limit switch:
during upward travel, press down the actuating lever by hand:
=> The load must stop immediately.
Document and file the results of the safety checks before initial operation.
4.2 Daily checks by the supervisor
• Check the correct fastening of the Yale endless winch on the suspen-
sion.
• Check functioning of UP and DOWN buttons as well as emergency-
stop button.
• Check functioning of the upper emergency-limit switch: During upward
travel, press down the actuator by hand:
=> The load must stop immediately.
• Make sure that no person stays under the suspended load or may be
able to stay there.
4.3 Weekly checks
Since defective ropes are a hazard to safe operation,
check suspension ropes and safety ropes for damage
at weekly intervals in accordance with section 6.2 A
and replace them, as required.
In order to increase the service life of the wire ropes, make
sure that they are clean and slightly lubricated. Check
supply cables and control cables at regular intervals and
replace them, as required.
4.4 UP / DOWN operation
A) Stop and emergency stop
a) For stopping the load, release the UP or DOWN pushbutton.
If the winch does not stop:
b) Press the emergency-stop button => the endless winch must stop
immediately
If the winch still does not stop:
c) Pull the CEE plug!
Stop working immediately if the load does not stop
as described in a)! Arrange for a qualified electrician
to carry out inspection and repair.
B) UP / DOWN operation
a) For switching the control system on, turn the red emergency-stop
button clockwise until it pops out.
b) Press the UP button for travelling upwards and the DOWN button for
travelling downwards. Release the button to stop the winch.
For lifting the load from the ground, always use the
lowest available lifting speed. The rope must first
be tensioned at this speed; it must not be slack
when the load is lifted from the ground. If the winch
has two speeds, the low speed must only be used
for short distances.
If operation is not possible check whether the inte-
grated phase sequence monitoring feature blocks
control because two phases in the supply line have
been changed over. Turn the phase changer in the
plug through 180°, as required.
c) The motor brake of the winch stops the load safely in every position.
4.5 Manual descent
In the event of a power failure, the brake of the winch motor can be
released by hand.
To do this, pull the lowering lever out of the handle on the rear side of
the winch and insert it through the opening of the cover of the motor
into the bracket of the brake.
Pull the lever upwards to start lowering the winch in a controlled manner.
A built-in centrifugal brake ensures that the lowering speed is limited.
Release the lowering lever to slow down. Always put the lever back into
the handle after use.
Using the manual descent in the case of an
overload is prohibited!
Using the manual descent as a replacement
for electrical lowering is prohibited!

In section 6.2 B
Use common multi-purpose oil or grease for lubricating.
Do not use any lubricants which contain molybdenum
disulphide (MoS2) or PTFE!
C) Motor and motor brake
The electro-motor of the winch is maintenance-free.
Clean the motor cover if it is extremely dirty to make sure that the motor
is supplied with enough air.
The motor brake is maintenance-free; it must, however, be kept free of
oil and grease!
Only clean in the case of exceptional operation conditions and in the case
of strong dirt accumulation.
6.1 Maintenance and servicing
A) Rope drive and gearbox
Rope drive and gearbox are almost maintenance-free.
Lubricating the ropes on a regular basis provides the rope drive with
sufficient lubrication.
The service life of the rope drive is considerably increased
by lubrication. The traction of the rope is not affected by
proper lubrication.
B) Wire ropes
• Wire ropes must always be slightly lubricated. Ensure that they are
clean, i.e. do not deposit them on dusty ground or in dirty surroundings.
• Never use wire ropes to fix a load.
• Always wind and unwind the wire ropes properly on/from the reels.
• Never pull wire ropes over edges.

6.2 Regular checks
A) Ongoing checks
Before and during operation always make sure that all components
used, i.e.
• Yale endless winches
• Yale safety locks
• Yale wire ropes
• Rope return sheaves
• Sling gear, etc.
are correctly fitted and are free of detectable defects.
Stop working immediately if defects occur during opera-
tion.
All type and instruction plates must be fitted and legible. Any missing or no
longer legible type and instruction plates must be replaced immediately!
Wire ropes must be replaced immediately if a defect
according to DIN15020 sheet 2 or ISO4309 has been
detected during the weekly check:
– more than 11 broken wires over a length of 24 cm (dia. 8) / 27 cm
(dia. 9) / 30 cm (dia. 10)
– Strong formation of rust on the surface or inside
– Heat damage, indicated by burning discoloration
– Reduction of the outer diameter to less than 7.6 mm (dia. 8 mm) /
8.5 mm (dia. 9 mm) / 9.4 mm (dia. 10 mm)
If damage is detected on the insulation or on the cable connections during
the weekly check of the electrical cables, replace or repair supply and
control cables immediately!

B) Safety check by a competent person
A competent person has been enabled to carry out safety checks on Yale
endless winches by adequate training at the manufacturer’s.
Safety checks of Yale endless winches must be carried out at least once
a year by a competent person.
Exceptional ambient conditions or conditions of operation may require
additional safety checks according to the relevant accident prevention
regulations for “Hoists, lifting and towing devices” (BGV D8) and the
standard “Cranes – Power driven winches and hoists” (EN14492-1).
Yale endless winches with M2/1Cm group of mechanisms must be
subjected to a general overhaul after 200 hours at the latest, and Yale
endless winches with M3/1Bm group of mechanisms after 400 hours of
operation, at the latest, by the manufacturer.
All results of the annual and extraordinary inspec-
tions must be entered into a log booklet.
This is the responsibility of the operating company.
6.3 Repairs of the winch
Any repairs on Yale endless winches must only be carried out by Yale
Industrial Products or a hoist service company authorised by Yale; only
original spare parts must be used for repairs.
Only use gear oil type Mobil SHC 632 for refilling or for changing the
gear oil!
