Advantages of 20T electric rotary hook blocks
(1) Complete high-altitude alignment by yourself. This kind of hook can make the hanging object rotate around the vertical line at high altitude to meet the requirement of alignment.
(2) Used in the harsh environment of harmful lifting workers. Where high temperature, dust, toxic gas and radiation are used, the electric swing hook can be used to complete the lifting operation without hoisting workers.
(3) Used in units with tight labor. Electric rotary hooks can be used to reduce the number of employees, reduce expenses and increase labor productivity.
In the above-mentioned occasions, the crane driver operates in the driver's cab, and the hanging object is rotated around the vertical line during the lifting operation, and the hook is not positioned after the alignment.
