Wire Rope Electric Hoist

Wire Rope Electric Hoist

Description

CD type Electric Wire Rope Hoist is a small-sized lifting equipment.Which can be mounted on all types of cranes,such as gantry crane,overhead crane,jib crane and other special crane to lift all types of material.With a small modification,it can also be used as a winch.What's more,it can be installed easily with different heights by hand control.

As a kind of general lifting equipment,model CD1/MD1 electric is equipped with Upper/Lower limit protector to ensure safe operation.It is widely used in material handling and cargo transloading in factory,mine field,railway paving site,goods station and warehouse.It is a good performance lifting mechanism in raising working efficiency and improving working condition.

As a small-sized lifting equipment,it has the advantages of compact structure,light weight,small volume,International Dimensions,easy-to-operate etc. Reducer adopts hard tooth surface driving design,which enjoys the long life span and high mechanical efficiency.The motor adopts  taper rotor brake motor,with the upper and down two-way security limit device.

There is only one CD Electric Wire Rope Hoist lifting speed;MD1 Electric Wire Rope Hoist is fast and slow two kinds of hoisting speed,steadily and accurately,for more precise assembly.

CD type Electric Wire Rope Hoist has only one normal speed,which can satisfy normal application while MD type Electric Wire Rope Hoist owns two speeds:normal speed and low speed.

When the MD type are in low speed,it can do precise loading and unloading,mounding of sand box,maintenance of machine tools etc.Thus model MD Electric Wire Rope Hoist is more widely used than model CD.

Features

Roller

The roller is made of high-quality seamless pipes and transmits power through spline. Its case is made of welded steel plate. This is the core part of the hoist.

Hook

The hook is forged and connected to the pulley assembly through thrust ball bearing, so the hook can rotate freely.

Hooks no more than 5ton lifting capacity are of single-pulley style and above 10ton is double-pulley style.

Wire rope

Adopts high strength wire rope with tensile strength of 1770 Mpa,, good safety performance and long service life.

Rope guide

Standard rope guide is made of Q235b steel.

Hoisting motor

The hoisting motor with large tractive force is employed to comply with the frequent direct traveling during course of working discontinuously.

CD1 model wire rope electric hoist is equipped with ZD style single speed motor, while MD1 is equipped with ZDS style double speed motor.

The difference between the usual speed and the low speed is 10:1.

Reducer

The gear and axes are made of alloy steel or qualified carbon-steel. All reducers adopt 3-level bevel gear. Proper heat treatment is conducted to ensure their reliability and service life. Finally, the box-body and box-cover are made of cast-iron. Both are well shake-reducing and sealed tightly.

Electrical equipment

The electrical mechanism consists of electric control box, limiter, button switch, connecting wire etc.

According to the marked direction on the button switch, press the button correctly and control the hoist through the on-and-off of the relay in the control box. The operating voltage is usually 36V.

Safety protection

* The accurate gear drive limiter is used as upper and lower limit, which can reliably cut off power circuit if hook moves to the upper or lower limit so as to stop the motor.

* Overload protector: the electric wire rope hoist is using electronic overload protector, so that the total lifting weight will not exceed the rated lifting weight; if the pulling force of steel rope is more than 105% of the rated capacity, the overload protector device would automatic cut off lifting loop.

* Emergency stop protection

* Over-heat protection of hoisting motor

* Over-current protection

* Phase protection

* Voltage lower protection
