winch
In a safe environment with no risk of falling, proceed
EN
according to the following instructions:
Install the work winch with its bracket on the mast of a
Davitrac™.
To check the correct operation of the lock, use a weight
weighing:
• 275 kg attached to the end of the cable for the work
winch;
Proceed to check the stopping of the weight following:
1. Lift the weight with the work winch;
2. Release the crank handle or button on the control
box;
3. The locking of the weight must be done immediately
without slipping;
4. Wait three minutes; and
5. Bring the weight back down.
If the lock is not immediate, if it occurs after several
jolts or if the weight goes down before the three-
minute delay, the product must not be used and
must be returned to Tractel
authorized Tractel repair center.
12.3.5.1. Additional check for the Carol MO

the lifting operation, the end of the cable must stop 50
cm below the Davitrac™ head when it is in position P1
at 700 m (according to the Davitrac™ instructions)
Non-compliance with the above check does
not necessarily mean the equipment is to be
decommissioned, but the device must not be used
until it has been repaired by Tractel or a Confined
space authorized Tractel repair center.
