Difference between electric hoist and crane trolley

The difference between the electric hoist and the crane trolley is that it contains different relations, different components and different driving modes.

1、 The inclusion relationship is different

1. Electric hoist: electric hoist is a light and small lifting equipment, belonging to a type of traveling crane.

2. Crane trolley: crane trolley is divided into light and small lifting equipment, bridge crane, jib crane and elevator according to its function and structural characteristics.

2、 Different composition

1. Electric hoist: electric hoist is composed of motor, transmission mechanism and drum or chain wheel. It is often equipped with running trolley and metal frame to expand the scope of operation.

2. Crane trolley: Crane trolley is composed of motor, universal coupling, flexible component and winding device, material taking device and braking device.

3、 Different driving modes

1. Electric hoist: the driving mode of electric hoist is centralized driving, that is, one motor drives the long drive shaft to drive the driving wheels on both sides.

2. Crane trolley: There are basically two types of driving modes of Crane trolley: one is centralized driving, that is, driving the driving wheels on both sides with a long drive shaft driven by an electric motor; The second is to drive separately, that is, the driving wheels on both sides are driven by an electric motor.
