Electric chain hoist with motor trolley 15t-25tons

OVERVIEW

Electric Chain hoist is a kind of light and small lifting equipment, which consists of motor, drive mechanism and sprocket. The chain electric hoist is produced in accordance with international standards. The body is beautiful in shape with strong and durable characteristics. Internal gears are all quenched at high temperatures, increasing the wear resistance and toughness of gears. Adopt international advanced technology, fine workmanship, tight fit between gears. Advanced structure and performance, small size, light weight, reliable performance, easy operation. The electric chain hoist can be controlled by the operator with pendant button on the ground or by wireless remote control.

DETAIL

1.Clutch

As emergency overload protection,Clutch will functions and motor will slip when abnormal load

2.Cooling fan

Cooling fan prevent motor over heat when long time continuous usage.Hollowed-out fan cover and cooling fin not only enhance fan heat dissipation capacity,but make fan operated more quietly.

3.Limit switch without guide frame

No guide frame ensures hoist lift and drag the weight diagonally.

4.The shell

Except for connecting case,all other parts hoist body adopt aluminum,light weight,but exceptional rigidity,as well as high dust-protection and water-protection

5.Side magnetic braking device

The magnetic force generator is the latest design which is featured for generating magnetic force.It allows instant brake as soon as the electric power is cut off.Thus the braking safety while loading is guaranteed.

6.Dual speeds hoist adopt built-in inverter

Adopt built-in inverter to make hoist in Dual speeds will reduces swing in operation,helps hoist start steadily and stop slowly.The speed ratio can be adjusted,the standard speed ratio is 4:1,if special requirement,please inform when inquiry.

7.Antiphase protector

Advatages : When power-supply wiring mistake, the control circuit is unable to move to protect motor
from being berned.

8.Hooks

It is hot forging with perfect strength that is hard to break.The operation safety of the lower hook is ensured by its 360 degrees rotation and safety tongue piece

9.Chain

High grade :It is made of Japanese FEC80 ultra strong heat treatment alloy steel.
Advatages: It is safely approximately when used in the rain water, the sea water, under the
chemical and other bad conditions.

10.Hand switch

An ergonomic shape design ensures hand switch operated friendly.The button with a light soft operating sensation satisfied the operator not fatigued after a long period operation

11.ISO

M4 /FEM: 1AM(M5 customized available)
Insulation grade: F
