Product Details
Function
The core hydraulic execution unit that drives the vertical extension and retraction of the support legs, achieving vehicle leveling and stable support
Cylinder diameter
φ 100-300 mm
Advantages and Characteristics
Ultra high pressure vertical bearing capacity:
working pressure of 30-50 MPa, peak pressure up to 55 MPa, single cylinder can provide 38-88 tons of vertical support force, suitable for heavy load scenarios such as wind power hoisting and bridge construction, and can still maintain support stability in a 10 level strong wind environment.
All terrain intelligent leveling system:
Combined with a laser level and an electro-hydraulic servo valve, the synchronization error of the multi leg vertical oil cylinder is ≤ 1mm (when the support height is 10 meters), and it supports independent leveling of one leg. It can achieve precise adjustment of the vehicle's levelness ≤ 0.3 ° on uneven ground with a slope of ≤ 7 °.
Anti impact and anti eccentric load design:
The cylinder barrel is made of 50Mn forgings and ultra precision honing, and the surface of the piston rod is plated with hard chromium and ultra precision ground, which can withstand eccentric load torque within 3.5 °;
Extreme environmental durability:
The sealing system adopts a combination of metal bellows and fluororubber, with a temperature resistance of -55 ℃~+180 ℃, combined with ceramic coating on the inner wall of the cylinder, and a service life of ≥ 200000 cycles in marine salt spray and high-altitude sand and dust environments;
The surface of the piston rod is coated with nano composite coating, which has a wear resistance 3.5 times that of traditional chrome plating and is suitable for frequent support operations.
