How To Choose A 10 Ton Single Girder Bridge Crane?

The daily operation of manual single-girder suspension cranes requires professional operators, and electric single-girder cranes also require professional operations.

First of all, starting from the definition, a manual single-girder crane refers to the operation of the crane, and the work of the lifting organization is completed by manpower. Generally, chain drive and large sprocket drive are used to achieve labor-saving effect. Manual cranes now have standard products.

Electric cranes have two modes of ground operation and cab operation. Electric operation is selected for ground operation, and the operation of the cab is similar to that of a manual single-girder crane.

Theoretically speaking, the primary difference between a manual single-girder crane and an electric single-girder crane lies in the different power principles.

As long as the manual single-girder crane has a reasonable structure, theoretically horizontal movement does not require too much force. Simply put, without lubrication and wheels, people only need to pay 15 percent of the weight to move; when using bearings and wheels, theoretically only need 0.1 percent -0.3 percent of the weight.

However, during the operation of the manual single-girder crane, when the height is too high, it is difficult to pull it by hand, and the working efficiency of this crane is low.

SL type manual single-girder crane refers to a single-girder crane driven by manpower. The biggest difference between this type of crane and the electric single-girder crane is that the power source is different.

The manual single-girder crane consists of main parts such as single-girder bridge frame, trolley running mechanism, manual monorail trolley, and chain hoist. The trolley operation and trolley operation are all driven by manual chains.

SL-type manual single-girder crane is used in warehouses, workshops or equipment maintenance without power supply where the handling capacity is not large and the efficiency and speed are not paid much attention to. The working environment temperature of this product should not be lower than -25 degree .

Electric single-girder overhead crane refers to a single-girder overhead crane driven by electricity.
