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.

Industrial overhead cranes play a crucial role in material handling operations across a wide range of industries. These robust and versatile machines are designed to lift and transport heavy loads with precision and efficiency.

Overhead crane trolleys are essential components of overhead crane systems, providing horizontal movement and positioning capabilities for lifting and transporting heavy loads.
