The assessment outline for the theoretical knowledge of the crane operation commander

Crane commanders play an important role in the work of hoisting machinery. They must cooperate with the crane driver to complete the lifting of heavy objects. They need to pass the assessment of relevant departments before they can take up their posts. The editor has compiled the theoretical knowledge assessment of the lifting machinery operation commanders. Share the scope with everyone.

G1 professional basic knowledge

G1.1 Basic knowledge of mechanics

Including the concept of force, the basic law of force, the synthesis and decomposition of force, the force analysis of the object's gravity and the center of gravity, the calculation of object mass, etc.

G1.2 Basic knowledge of cranes
