PROLH PROFESSIONAL LEVER HOIST

The PROLH professional lever hoist is equipped with a one-piece toothed gear and ratchet system. It has a unique double brake mechanism that automatically closes when the hoist meets the least resistance on the lower hook. This function allows you to lift, hold and lower even the lightest loads without slipping. It uses an eight-point multi-turn gear shaft, which extended the brake response time. The brake's rotational coupling acts in the direction of the load-bearing load, creating highly effective braking factors - up to 50% of the measurable difference compared to longitudinal 4-point teeth.

PROLH is used in the overhead industry, shipyards and drilling platforms, and is also suitable for use in underground mining.

PROLH lever hoists meet and exceed all requirements of BS EN 13157: 2004 + A1: 2009, ANSI / ASME B30.21, AS1418.2 and SANS 1636.
