industrial electric overhead travelling crane is horizontal frame in the workshop, warehouse and open storage yard above, used to lift all kinds of objects of mechanical equipment.

The explosion proof bridge crane is a type of lifting equipment specially designed for lifting in explosion hazardous environments. explosion proof overhead travelling crane is widely used in the chemical, oil, gas and mining industries where explosive gases, vapors or dusts are present. 

We often see some double-girder crane models such as QD16/3.2. 16 and 3.2 both have lifting capacity. One is the main hook and the other is the auxiliary hook.

The operation of semi gantry crane is very simple, which makes many users think that the hoisting operation of the crane is not technical, but this is not the case.

Semi gantry crane, as the name suggests, is a deformation of the traditional gantry crane, and it is a kind of lifting machinery equipment between bridge crane and gantry crane.

Since the first 5t cantilever semi-gantry crane independently designed by Sevencrane was put into use, all performance indicators have been good and met the design requirements.
