FEATURE DESCRIPTION

1. General
>>Safe working load 0.5t - 80t
>>DIN/FEM/ISO standard, lightweight construction
>>Silent operation
>>Lower hoist frame, building cost saving
>>Modern design of motor, fan, gear, drum, brake combined with construction of the hoist
>>Optimum cooling, cooling improved up 30%, resist 170°C as standard
>>Ambient temperature -10℃ – +40℃
>>Painted with 140μm epoxy paint for maximum resistance against climatic conditions, extending the hoist’s working life


2. Lifting motor
>>Asynchronous squirrel cage motor (Synchronous speed 3000rpm)
>>Two-speed pole changing or frequency invertor for stepless control
>>Heavy duty, 60% ED rating
>>F class insulation, IP55 pretection
>>Lifting gear box
>>Sealed gearbox housings are made of aluminum
>>Totally enclosed semi-fluid, lifetime designing
>>Helical type, hardened and ground gears


3. Lifting brake
>>DC Electromagnetic disc brake
>>No adjusting requirement for brake lining, maintenance free
>>Motor and brake working together, brake torque is at least 1.8 times higher than the nominal torque of the motor, not slip at any point of starting or stopping of the hoist or lower motions
>>Fully covered, dust proof
>>Heavy duty brake
>>Adjustable brake toque
>>Brake linings are asbestos-free
>>Super life time, 1 million normal braking times, 500 emergency braking times


4. Rope Drum
>>Large diameter rope drum, Drum dia /rope dia=46, and rope pulleys extend the rope’s lifetime
>>Ensures accurate load positioning, hook drift +/- 4mm per 1m
>>Min. two dead rope turns while the hook is in the lowest position
>>Rope guide is wear resistant, heavy-duty, made of spheroidal graphite cast iron
>>A spring operated guide roll in the rope guide prevents slack rope


5. Steel Wire Rope
>>High tensile steel wire rope, wire strength 2160N/mm2
>>All galvanized as standard


6. Hook
>>DIN 17200 standard Hook, quenched and tempered 34CrMoV steel
anti-friction lifetime lubricated bearings and rotate freely 360 degrees
>>Spring-loaded sturdy safety catch, ensuring slings not release


7. Safety feature
>>Overload protection: equipped self re-setting overload protector, the hoist motion is stopped if overloading occurs, but lowering is permitted, making the crane safe
>>Lifting limit switch: adjustable, geared 4-step rotating limit switches, self re-setting, slow down and stop
>>End stop: energy-absorbing rubber buffers
>>Wireless anti-collusion limit switch: infra-red type
>>Overheating protection: equipped with imbedded bi-metallic thermal switch (or thermistors) in the windings to protect against overheating
>>Electrical braking is provided in all circumstances and the mechanical brake is used only as a holding and emergency brake
