General Manual Electric Winches with UMPH rope-English Rev.1.1 – 10-12-2014
24. Limit switches are installed as a safety device; they are not suited to be used as positioning devices;
25. Swinging loads will significantly increase the products load and must be avoided;
26. Do not handle wires without accident prevention gloves and never try to move wires under tension;
27. Make sure that wire size and features are compatible with winch ones and check the correct fastening
of the wire to the drum. Always maintain three or more wraps of rope on the drum:
28. Check the wire winding sense on winch drum for correctness and conformity to the one stated on winch
data sheet. The correct winding contributes to extend wire's operational life;
29. Check wire integrity and absence of broken strands or kinks which may cause wire breaking;
30. Check safety device operation and efficiency;
31. Make sure that working conditions conform to winch features;
32. Never lift loads exceeding maximum safe working load (W.L.L.).
33. Beware of snatch loads on the winch. Any sudden loading can cause excessive acceleration forces on
the winch system, resulting excessive wear or even complete failure. Snatch loads are usually only
found in pulling applications or traversing systems. One way of avoiding them is using a rope leader of
sufficient safety factor (usually SF6) which will stretch when loaded.
34. Some applications such as windlasses, mooring winches and towing winches require significantly
higher than normal break loads. Ensure that the winch is suitable for these applications.
35. When ropes become slack on the drum, they will tend to expend, resulting in: "cutting in" of wire when
the winch is loaded again or the wire coming of the drum and jamming elsewhere on the winch (e.g.
around the winch shaft). Both situations will cause serious damage to the wire requiring replacements.
36. Do not try to move fixed or obstructed loads
37. With winches for lifting and lowering suspended loads, side-pull of load is not allowed.
38. Excessive inching (e.g. giving short pulses to the motor) shall be avoided.
