HCL506, 550 kN Capacity, 150 mm Stroke, Single-Acting, High Tonnage, Lock Nut Hydraulic Cylinder

Enerpac HCL506 is a robust single-acting high tonnage lock nut hydraulic cylinder designed for heavy-duty lifting and load holding in industrial maintenance, construction, and foundation leveling tasks. Delivering a 62 US ton (550 kN) advance capacity over a 150 mm stroke, this model ensures positive mechanical load holding independent of hydraulic pressure, operating at up to 10,150 psi with 10% side-load resistance, hardened surfaces for cyclic wear, and weather protection for reliability in harsh environments.
