Product Introduction

TYD-S Series Double-Acting General Hydraulic Jacks are professional high-pressure hydraulic tools for industrial heavy-duty lifting, pushing and pulling operations. Equipped with dual oil ports, both extension and retraction are driven by hydraulic oil, featuring fast retraction speed and much higher working efficiency than single-acting cylinders, capable of bidirectional lifting, pressing and pulling work. The cylinder barrel is made of high-strength alloy steel, precisely machined by imported CNC lathes, drilling and grinding machines after premium heat treatment. With anti-corrosion coating on the surface, imported sealing kits and dust-proof rings, the cylinder is wear-resistant, leak-proof and durable. NPT 3/8” male high-pressure connectors with dust caps are installed on both ends. Heat-treated anti-slip grooves on the plunger head eliminate the need for a saddle seat. Compatible with double-circuit electric hydraulic pump stations, it is widely used in steel structure correction, heavy equipment pushing & alignment, bridge maintenance, mold disassembly, locomotive overhaul and all working conditions

Feature

• Double-acting hydraulic circuit design enables hydraulic forced retraction with fast return stroke, greatly improving overall working efficiency.

• Anti-corrosion surface treatment with glossy finish, effectively preventing rust and oxidation during long-term indoor and outdoor service.

• Constructed from high-strength alloy steel with advanced heat treatment, precision processed by imported CNC machines for solid structure and stable pressure resistance.

• Hydraulic forced retraction is not limited by load weight; the plunger retracts steadily and rapidly under both light and heavy loads.

• Imported sealing assemblies reduce friction loss, supporting long-time continuous operation with low risk of abrasion and oil leakage.

• Built-in dust-proof sealing ring blocks dust and impurities to avoid internal contamination and extend the cylinder service life.

• Both ends of all models are fitted with NPT 3/8” male high-pressure connectors and matched dust caps to protect thread fittings from dirt and impact damage.

• Heat-treated anti-slip grooves on the plunger head provide strong friction, no saddle is required for lifting operations.
