Telescopic boom cranes can be hydraulic extended and retracted without a knuckle function. These cranes should always be executed with a hoisting winch installation.
1.Telescopic Marine Crane is composed of base, arm frame, tower, hydraulic winch, telescopic oil cylinder, Amplitude oil cylinder, hydraulic rotary mechanism, operating platform, hydraulic transmission parts, electric controlling part and etc.
2.The base is cylinder structure, can be welded on the deck, also can connect with deck by high strength bolts. Connection mode must to be marked.
3.Arm frame and tower are box structure. Hydraulic winch controls the goods rising and drop. Telescopic oil cylinder controls level the telescopic crane boom. Amplitude oil cylinder controls goods correct hook-on point and landing point.
4. Swing mechanism for controlling crane turning right or left turn. Operation platform is used for operation and maintenance debugging. Hydraulic transmission parts for the system to provide pressure oil; The electrical control system mainly control motor stops, operation.
