Mtrac winch for passenger elevation

3.3 Fixing of the Yale winch

A) Mounting material

Yale winches for passenger elevation of the YMT-P 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 winch

Fix Yale 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 and safety
rope as well as the component on which the winch and the safety lock are
fixed must have

at least 4 times the load capacity

(plastic deformation

permissible) compared with the useful load of the winch and/or the safety
lock in order to meet the requirements of standard EN 1808.

3.4 Yale control systems

A) Control system for one winch for passenger elevation with
control pendant

A CEE-16A plug is provided on the control system for one winch for
power supply to the winch for passenger elevation. 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.

For this type of control system, the mains voltage supply
must be protected by means of an overcurrent protective
device and a 30 mA current-operated earth-leakage circuit-
breaker.

B) Control system for one winch for passenger elevation

A CEE-16A plug is provided on the control system for one winch for
power supply to the winch for passenger elevation. The control elements
for operating the winch for passenger elevation and the emergency-stop
pushbutton are arranged on the door of the switching cabinet of the
control system. The main switch of the winch for passenger elevation is
also located on the control system.

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 winches for passenger elevation

A CEE-16A plug is provided on the control system for two winches for
power supply to the winches for passenger elevation. The control ele-
ments for operating the winch for passenger elevation and the emergency-
stop pushbutton are arranged on the door of the switching cabinet of the
control system. The main switch of the winch for passenger elevation 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 manufacturer of the access equipment is responsible for the connection
of the Yale winches for passenger elevation. 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!
