SELECTION
The chart below shows the maximum working load and breaking strength of 7 X 19 Galva-
nized AIRCRAFT Grade Wire Rope in various diameters. The breaking strength is 3-1/2
times the maximum working load. Do not use wire rope with a Maximum Working Load rating
less than the single line capacity of the crane. Use of wire rope diameter larger than the size
furnished with the crane will reduce the fatigue life of the wire rope.

INSTALLATION
1. Unwind coil of rope by rolling it along floor. This will prevent kinking.
2. Most VENTURO Cranes are provided with a slot in the winch drum side plate for attaching the
end of the wire rope with a stop collar. A hole in the housing allows access for the end of the
wire rope when inserted thru the slot.
The ET20K(X) & ET25K(X) Cranes have a clamp built into the winch drum and do not use a
stop collar.
3. THERE MUST ALWAYS BE AT LEAST (3) TURNS OF WIRE ROPE ON THE DRUM WHEN
UNDER LOAD.
