Advantages of Rotating crane hook blocks
(1) perform upper-air counterpoint by oneself.
This kind of hook can make the hanging object revolve around the plumb line at high altitude, and reach the requirement of position.
(2) bad environment harmful to the health of hoisting workers.
If high temperature, much dust, have gas and radiative place, use electric to turn hook can finish hoisting operation, need not hoisting worker.
(3) used in units with tight labor force.
The use of electric rotating hooks can shrink staffing, reduce costs and improve productivity.
The crane driver operates in the driver's cab on the above occasions, and rotates the object around the plumb line on the way of hoisting, so that the hook will not rotate after positioning.
