OY1058-2 3Ton Steel Aluminum Floor Jack (Dual pump)

OY1058-2 3Ton Steel Aluminum Floor Jack is the highest-capacity model in the hybrid aluminum-steel jack subgroup, rated at 3 tons with a construction that integrates a steel internal load-bearing structure within an aluminum-body chassis.
At 3-ton capacity with a lifting range of 85mm to 490mm, the OY1058-2 competes directly with all-steel 3-ton floor jacks in load performance while benefiting from the corrosion resistance of its aluminum outer components. The steel-reinforced ram and cylinder assembly are built to withstand the higher cyclic stress of sustained heavy-duty use more effectively than a purely aluminum equivalent.
The dual-pump system is tuned for the steel-reinforced internal hydraulic circuit, delivering controlled, progressive lifting at full rated load. The main frame casting is thickened at joint zones compared to the lighter 2.5-ton hybrid sibling, reflecting the increased structural demands of the 3-ton rating.
Integrated safety systems include a calibrated overload valve and a positive-locking descent control. The rubber saddle is appropriately dimensioned for the wider contact area of heavier vehicle undercarriage points.
Best suited for workshops requiring 3-ton steel-grade lifting performance in environments where corrosion protection of exterior components is a consideration, offering more structural resilience than a pure aluminum equivalent of the same capacity.
