WARNING!
Never allow the rope to override on the Winch drum. This can cause the rope to jam and prevent
the load from being lifted/lowered. To eliminate override, reduce the tension of the load on the rope.
This procedure has a risk of serious injury or death if the load falls or becomes uncontrollable.
3. Pass the rope between the two rope grabs. To facilitate the operation, lift the cover (see figure
17.4).
WARNING!
Make sure that the rope is correctly positioned on the stripper arm and inside the spring pre-loaded
self-locking rope grabs (see figures 17.6-17.7).
LIFTING (ALL VERSIONS)
1. Start by turning the handle counter-clockwise (see figure 17.8). The gears are engaged automatically
according to the direction of rotation.

gear (faster = less power): turn the handle counter-clockwise.

2. When the handle becomes difficult to turn in 1st gear, invert the direction of rotation to engage the
2nd gear (see figure 17.9). A higher power ratio (2

NOTE!
The maximum inlet speed of the Top-Crank LokHead Rigging Winch 500 is 60 rpm.
LOWERING LOADS (ALL VERSIONS)
To lower the load, grab the rope coming out from the Winch with a hand and the knob with the other
hand. Rotate the knob slowly clockwise (see figure 17.2).
The sheaves will open and to allow the rope to slide over the Winch drum and ensure a controlled
descent of the load. To adjust the descent speed, check the opening of sheaves manually through the
knob.
To stop load lowering, release the knob completely.
During lowering/descent of the load, avoid loosening the rope between the anchorage point and the
person.
