HSCP Series S/A Hydraulic Pull Cylinders
Engineering Overview & Structural Features
The HSCP Series Single-Acting Hydraulic Pull Cylinders deliver dependable tensile pulling force from 2.5 to 50 Metric Tons at full 700 Bar (10,000 PSI) working pressure. Designed for tough structural alignment, shipyard plate joint pulling, cable tensioning, and heavy machinery positioning, HSCP cylinders utilize precision-wound internal return springs to achieve fast, uniform stroke reset. Fitted with replaceable drop-forged clevis links or collar/base fixture threads, the series provides versatile, fail-safe pulling strength across demanding construction and industrial maintenance environments.
Structural Features & Engineering Advantages
Heavy-Duty Spring Return Mechanism
Pre-stressed heavy-duty straight-pull internal springs provide rapid, smooth piston extension upon hydraulic pressure release, significantly shortening cycle reset times in repetitive tensile operations.
Hardened & Hard-Chromed Pull Rod
Precision-ground high-alloy pull piston rod undergoes induction hardening and dense hard chrome plating, protecting sliding contact surfaces from abrasive grit, scoring, and atmospheric corrosion.
Integral Safety Relief Valve
Built-in safety relief valve prevents dangerous over-pressurization and limits accidental cylinder over-extension at maximum stroke travel, safeguarding structural assemblies and operators alike.
Removable Clevis Eyes & Threaded Mounts
Configured with heavy drop-forged alloy link eyes on both ends or standard collar and base threads, allowing direct connection to tension cables, master links, chains, and custom pulling fixtures.
Monobloc Body & Baked Enamel Coating
High-strength monobloc forged alloy steel body withstands extreme tensile reaction forces without barrel deformation, finished with an electrostatic baked enamel coating for long-term corrosion resistance.
Standard High-Flow Quick Coupler
Comes standard equipped with a high-flow 3/8"-18 NPT quick coupler and heavy-duty dust cap, preventing contamination ingress and ensuring maximum hydraulic flow rate during high-cycle pulling operations.
Dimensional Engineering Blueprint
Dimensional designations (A: Collapsed Height, B: Extended Height, D: Outside Diameter, J: Link Height, L: Link Opening, M: Link Thickness, N: Link Width, T: Slot to Link End) correspond directly with factory technical selection parameters.
