Definition:
The telescopic offshore crane is composed of base, boom, tower, hydraulic winch, telescopic cylinder, amplitude cylinder, hydraulic rotary mechanism, operating platform, hydraulic transmission part, electric control part, etc.
The base is a cylindrical structure that can be welded to the deck or connected to the deck by high-strength bolts. The connection mode must be marked.
The boom and tower are box-type structures. Hydraulic winch controls the lifting of cargo. The telescopic cylinder controls the level of the telescopic crane arm. The amplitude cylinder controls the correct hook point and landing point of the cargo.
The swing mechanism that controls the right or left turn of the crane. The operating platform is used for O&M debugging. The hydraulic transmission part provides pressure oil for the system; The electrical control system mainly controls the stop and operation of the motor.
Boom cranes are impressive, due to their exceptional weight/power ratio and their ease to maintain.
Their slender design and ability to attach additional winches make them attractive to operators of working, passenger and marine vessels.
Demountable crane booms simplify transport.
