GIS expands entertainment hoist range

Electric chain hoist manufacturer GIS AG has expanded its LP electric chain motor series for the entertainment industry with the addition of two new models, the LP1600 and LP2500. The latter takes the capacity range to 6,300kg. At the same time, the new GHF/GMF generation of manual and motorized trolleys is also being put to market.

The LP1600 lifts 1,600 kg in the D8+ version, the LP2500 2,500kg.

The manual (GHF model) and motorized (GMF model) trolleys, meanwhile, are available in four sizes, and are adapted to the new LP motors. The push trolley with manual parking brake is available especially for the entertainment industry. Both the LP series electric chain motors and the GHF/GMF trolleys are Swiss made and offer the combination of functionality, reliability and durability. Compared to the previous models, the hoists are designed for up to four times and the trolleys up to two times the service life, guaranteed by an extended warranty of three years.

Capacity increase

A second brake can be easily mounted on the existing shaft without the need for a housing extension. The hoists can be used as climbing or stationary motors and can easily be supplemented with incremental as well as absolute encoders for path measurement, load sensors, temperature or brake monitoring. The two motors can thus be configured in accordance with the application and country-specific requirements.

Encoders for path measurement can be mounted on the chain wheel or on the rotor shaft. Special eye and hook suspensions allow easy installation of a load sensor.

Widmer pointed to other standout features of the new LP electric chain hoist models, including the case-hardened, manganese phosphated profile steel chain. In comparison to the conventional round steel chain, it offers a 15 per cent greater load-bearing capacity with the same nominal diameter.

As with the existing LP models, protection class IP65 is standard, guaranteeing both dust-tightness and protection against water jets. With compact, robust design, every LP chain hoist is suitable for outdoor applications, even in the most demanding conditions. The self-contained, helical geared three-stage transmission with permanent grease lubrication ensures the quietest possible operation, while the powerful flange-mounted motor with high power reserve ensures excellent synchronization for group trips.
