Through the efforts of the designers, the design and development of a simple and adjustable main beam crane has been successful, solving a gap in the application of domestic cranes. Cranes always encounter insurmountable obstacles during lifting,

These obstacles to some extent hinder the normal use and operation of the crane, and there are many places that the crane cannot pass through during operation. This situation solves the obstacle crossing problem of the crane during operation,

The maximum design tonnage is 5t.

The maximum span is 10 meters.

The maximum lifting height is 10 meters.

The maximum lifting height is 1.5 meters, which is one-third of the total lifting height.
