Ultra-Low headroom chain hoist with geared trolley CR type
The ultra-low manual chain hoists CR type with running on the lower flanges of the beam, are planned only to lift free weights in the space, straight up in condition and controlled efficiency, in according to the measures and limits of use as described in the instructions of use and using accessories that the grip element (lifting hook) and the upper base (hanging hook) allow.
TECHNICAL AND CONSTRUCTION CHARACTERISTICS:
Structure: compact and light
Reducer: coaxial with high-resistance cylindrical steel gears. Module toothing entirely supported on a ball bearing closed in a carter permanently lubrificated
Load sprocket: with four pockets, molten, thermally treated for a perfect running of the carrying chain.
Chain guide and extractor: guarantee a precise housing and a perfect extraction of the carrying chain either in raise or in descent.
Brake: with a safety jump to stop the weight in the wanted position. The brake is automatic at weight pression and has two friction joints free from asbestos.
Carrying chain limit switches: composed of two steel plates fixed on the discent side of the chain that avoids the chain going out.
Hanging and lifting hooks: high resistant, in tempered steel, turning with ball bearing, with a safety davice to avoid unhitching.
Carrying chain: in high resistant steel, with round links, superficially, hardened, cpvered with zinc to obtain a high resistance to wear, corrosion, ageing.
Moving/hand chain: in roud steel, running on a pocket pulley. Chain and pulley are protected by a steel sheet side cover.
Sides: in steel sheet, above which the pins of the motion.
Wheels: in cast iron mechanically worked, with a rolling strip appropriate to the expected running beam. The wheels are supported on permanently lubricated ball bearing (simple or double). Two wheels are idle and two wheels are driving.
Hoist control: the hoist is activated by pulling manually one of the descent falls of the moving/motion chain.
Trolley control: the trolley is activated by pulling manually one of the descent falls of the moving/motion chain.
