This range of explosion-proof winches provides the solution for pneumatic winch applications demanding lightweight construction. The use of vane type motors and inherently safe self-braking wormgears ensures trouble-free operation and low maintenance. These winches find their use in general industry, oil and gas exploration, and in many places where compact, hoisting gear is required. The range includes two fast speed types, the LV 256 and LV 508, which also have optional carrying handles, and slower speed types up to 1700 kg of lifting capacity. The self-braking properties of the wormgear drive combined with closed ports is suffi cient for almost all hoisting purposes. An additional brake may be necessary for accurate positioning of a load. Please consult the factory in this case.

Standard features

• Self-braking wormgear transmission
• Rotary vane motor
• Steel drum (not grooved) with cable fixing point at flange
• Two drum supports
• Double layer 2-component conservation according ISO 12944 category C2-Low, colour RAL 5010
