Working duties: A7, A8, heavy duty
If the requirements are more than above-mentioned, pls tell us for special design! 
Control mode:
Wireless control, cabin control. 
Trolley
It consists of metallurgy motor, gearbox, hydraulic brake, coupling, wheels, and wire drum. 
Equipped with special motor for metallurgy, class of insulation is H; 
Matched with two sets hydraulic brakes(double brake)
Trolley have double drive mechanism, reducer's gear is drived on hard-toothed surface
Features: 
--China Top assembly with best prices. 
--Strong box type, welding by machine hand
--Thermal-protective coating is added at the bottom of the main girder. 
--Crane wheels are vacuum casting, machined by CNC machines, medium-frequency quenching, top quality control. 
--Wirerope drum, gears, couplings shafts are machined by CNC manchines, top quality control. 
--Heavy duty slipring motor, or, squirrel cage motor with VVVF, IP 54 or IP44 with insulation class F or H, soft starting and smooth running, could meet frequent using. 
--Siemens or Schneider main electric parts are used for durable working and energy saving! 
--Soft starting and stopping, smooth running
--High working efficiency, commfortable and safe operation
--Low maintenance, low cost mainteannce
Safety: 
Weight overload protection device
Top quality polyurethane buffer
Crane travelling limit switch and lifting limit switch
Voltage lost protection function, when power is failuire then it needs reset all function to start working. 
Emergency stop system, in case of emergency, the operatore could use emergency stop button to cut off power and stop the crane operation immediately to protect human and relevant property. 
Current overload protection function. 
Phase protection function.
 
Painting:
