GIS Launches New Chain Hoists, Trolleys
Swiss electric chain hoist manufacturer GIS AG has launched two additions to its GP series and a new generation of trolleys.
The GP1600 and GP2500 electric chain hoists expand the capacity of the range to 6,300kg, while the GHF/GMF manual and motorised trolleys match-up with higher capacity in addition to optimised, quiet running and extended service life.
The GP2500 is a first in the company’s 60-year history in that it enables an increase in capacity from the previous 5,000kg in two-fall operation and lifts 3,200kg in a single fall. The GP1600 boasts a lifting capacity of 2,500kg (one fall) or 4,000kg (two falls). The range now extends from the 12kg light GPM250, with 320kg lifting capacity, up to the two new powerhouses—available immediately.
As with existing GP models, protection class IP65 is standard, guaranteeing dust-tightness and protection against water. With its compact, robust design, every GP chain hoist is suitable for both dusty environments and outdoor use. All shaft-hub connections are manufactured to a self-centring polygonal design.
Erich Widmer, sales and marketing manager at GIS AG, said: “Disassembly and assembly during maintenance work is therefore faster and requires no special tools, which reduces service costs. The low-wear DC spring-loaded brake, as well as a contactor control without sensitive electronics, ensures further operational safety.”
For applications with an exceptional duty cycle in addition to high switching frequency (multi-shift operation) a version with a frequency converter is available. Variable speeds and a soft start ensure precise, gentle positioning of the load. ATEX versions (dust or gas protected) of the GP1600 and GP2500 can be used in explosive environments.
The new trolley generation, meanwhile, consists of manual (GHF model) and motorised (GMF model) versions, with a 26% higher capacity compared to previous models. A stepless, variable flange width facilitates on-site installation.
The GHF/GMF trolleys are designed for maximum flexibility and durability. They are available in four sizes with capacities of 1,250kg, 2,500kg, 5,000kg and 6,300kg. The helical gear and flat or convex rollers, with a larger diameter, can be tuned to the wing to ensure a longer service life.
Widmer said: “The flange width is steplessly variable thanks to a new type of adjustment system and can be fixed positively by means of a locking function.”
Importantly, the trolleys are matched-up to the GP chain hoists and form a compact complete unit. The product can also be used as components for end carriages of underslung overhead travelling cranes and are available with frequency converters for movement of the load without overshooting.
Widmer said the trolleys feature side plates made of grey cast iron with integrated fall and climbing protection and are also available in a corrosion-resistant version up to 1,250kg capacity for the food; chemical and pharmaceutical; wastewater treatment; and outdoor applications.
He added: “Both the electric chain hoists of the GP series and the GHF/GMF trolleys are made in Switzerland; they are robust and designed for tough, everyday use.”
Both products are guaranteed by an extended warranty of three years.
