Product Details
Function
The core hydraulic actuator that supports the slewing motion of the boom and drives the boom to adjust the slewing angle
Cylinder diameter
60-180 mm
Advantages and Characteristics
Extreme pressure bearing capacity:
working pressure of 24-34 MPa, peak pressure exceeding 40 MPa, single cylinder can provide 18-28 tons of thrust, stably carrying the composite load of the crane arm and lifting heavy objects, and coping with complex lifting conditions.
Impact resistance and stability:
The reinforced cylinder/piston rod material (such as 27SiMn alloy steel) and multi-layer sealing system are used to absorb the instantaneous impact of the boom amplitude start stop, suppress hydraulic oil leakage, ensure a smooth amplitude process, and avoid the shaking of the lifted object.
Safety redundancy design:
Equipped with a built-in buffer valve and emergency pressure protection device, the boom slowly retracts in case of sudden pressure loss to prevent the object from falling; The cylinder body is equipped with an overload protection structure to avoid the risk of overpressure damage and safeguard the safety of lifting operations.
