Truck crane is installed on the chassis of the car, can be in a certain range of vertical lifting and horizontal movement of heavy loads of multi-action crane, also called truck crane, belongs to special equipment vehicles, foreign truck crane mainly Sweden, Italy, Austria, Germany, the United States, Japan, Canada and other more than a dozen companies.
CNS crane is produced by the hydraulic transmission principle to achieve a variety of mechanical actions. We commonly use car power to drive the hydraulic oil pump through the force extractor and connect the hydraulic valve to achieve work. If there is no car power, the power source can be provided by the oil pump electric unit. Oil pump electric unit is in the field, docks, ships, workshops and other conditions without car power, through 380V voltage to drive the motor work. If it is a field operation, it also needs a generator to generate electricity, and the oil pump is driven by the motor.
CNS crane is made up of lifting arm, column, frame, leg and hydraulic components. The boom of the crane is the main device to lift the goods during lifting. The column is an important part connecting the boom and the frame, and the goods mainly rely on the column when rotating left and right. At present, the domestic straight-arm crane can reach 360 degrees of full rotation, and the frame is mainly connected and fixed the column and leg components. The main function of the leg is to maintain the balance of the crane during crane operation to ensure that more goods will not overturn. The hydraulic system is composed of oil tank, oil pump, oil cylinder, multi-way reversing valve, hydraulic lock, balance valve, relief valve, sequence valve, reducer, motor, rotary center joint and pipeline. In addition, there are hoisting machinery, rotary mechanism and so on. In order to meet the safety needs of users, there are alarm devices, hook wire rope devices; And in the telescopic form of the boom, rotating structure, the manufacturers have made innovation, diversified forms.
