3  ton electric wire rope hoist  with  EUROPEAN  TYPE

It employ motor of hoisting mechanism and reducer imported from Germany . the integrated and compact design of hoisting motor. Reducer, reel and limit switch saves space for the user.modular design increase the reliability of mechanism meanwhile reduces the time and cost for maintaining.

 It has more and faster hoist speed and various pulley ratio which can be selected. the standard traveling mechanism of trolley is controlled by converter, with speed of 20m/min, which makes  a title swing and accurate position if hoisting items while trolley traveling as well as valuable items reliably.

1: Reel

The reel is made of high-quality seamless pipes and process by numeral control machine, after the special finishing ,the rope groove on reel works coordinately with rope guide to efficiently  prevent rope loose and tangling

2: steel rope

Employ importing steel rope with high strength which has tensile strength of 2, 160kn/mm2, with good safety performance and long service life .

3: rope guide

 Standard rope guide is made and processed by engineering plastic with strong abrasion resistance and good self-lubricating performance .which greatly reduces the wear of steel rope as main force safety of hoisting mechanism.meanwhile ,direct to different use condition ,the heavy-grade rope guide made of nodular cast iron is also allowed.

4: motor of hoisting mechanism

The hoisting mechanism employs double-winding squirrel –cage pole-changing motor to achieve speed ratio of 1: 6 shell of motor is made of aluminum alloy by extruding, which has good dissipation .the fan is installed to the end of motor on order to enhance cooling effects. Thermal resistor (or thermal switch ) is embedded into winding group of motor to prevent probable motor overheating.

The motor has F insulation level and protection level IP54.

  As to the variable –frequency motor of hoisting mechanism , encoder is allowed to install ,which is ordinarily installed to fan shaft end of motor.Technical feature :

It has low current for start and large torque .

With soft starting and good performance in speed up  

have long service life

the technical parameter comply with standard of FEM and HMI

with high rotational speed and low noise

5: brake

  The motor of hoisting mechanism is provided with double-disc electromagnetic brake. brake integration locates at the end of motor. The brake will automatically close if the motor power off in order that avoid load slipping off .the brake clearance doesn't need to be manually regulated (which can be regulated automatically by brake spring ) after being initially set ; if the thickness of brake pad is lower than the setting, it will automatic alarm through additional monitor switch in order to remind user to replace it. Double-disc electromagnetic brake Iis safe and reliable ,the brake torque is higher than 1.8 times of rated torque, the number of braking gets to 1, 000, 000 times and it doesn't need maintenance in the safety service circle.

  Technical feature :

  Have fast movement and high reliability.

  It's maintenance –free and self-regulated.

  Employ dustproof design and long service life.
