Mtrac endless winch
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 di 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.
