Before using the jib crane, the operator should ensure that the hook should be of sufficient height without any obstructions. Before the crane hoisting materials, the jib should be moved in place so that it is above the hoisted object. Lift and accelerate gradually, then move the arm slowly. When approaching the position where you want to stop the arm, slow down.
