This platform raising cylinder series is the core power component for the drill floor lifting system of truck-mounted rigs, workover rigs, and modular drilling units. It smoothly raises the drill floor (complete with rotary table, drawworks, etc.) from a low transport position to working height, and safely lowers it back. Designed with a high-thrust, long-stroke multi-stage telescopic configuration, it achieves vertical lifting strokes of several meters up to nearly ten meters from the carrier’s compact installed length, easily bearing the immense total weight of the drill floor and all attached equipment. Integrating a high-strength lightweight structure, low-friction long-life seals, and integrated safety locking valve packages, it ensures stable lifting and zero-drift locking even in extreme environments such as desert, Gobi, or coastal salt spray, significantly improving rig mobility and operational safety.

Features & Benefits

High-Thrust, Long-Stroke, Lightweight Design
Finite element structural optimization and high yield-ratio quenched & tempered alloy steel allow precisely calculated wall thicknesses, achieving ultra-long strokes and thousands of kN of thrust from an extremely compact retracted length. Weight is reduced by 10%–15% compared to conventional designs, lowering chassis load and improving road safety.
Anti-Drop Safety & Synchronized Control
Standard integrated high-flow counterbalance valve or hydraulic lock allows the drill floor to be safely stopped and locked at any height. The cylinder instantly self-locks even if a hose bursts or system pressure is lost, preventing accidental floor drop. Optional multi-cylinder synchronized lifting control valve packages and built-in displacement sensors (±0.5 mm accuracy) enable coordinated, smooth raising/lowering without platform tilt or distortion.
Ultra-Low Friction & High Side-Load Resistance
Wide, one-piece high-capacity composite guide rings at every stage, combined with low-friction filled PTFE seals, achieve breakaway pressure down to 0.4 MPa. Even under off-center platform loads or wind forces, the cylinders extend and retract smoothly with no stick-slip or judder, and without rod scoring.
Comprehensive Surface Protection
Piston rods are available with hard chrome, Ni/Cr alloy plating, laser cladding, or ceramic spray. The barrel exterior receives corrosion-resistant weatherproof coating, maintaining a rust-free appearance and lasting performance in coastal salt spray, desert sandstorms, and arctic conditions.
Wide-Temperature-Range Reliable Sealing
Standard -40℃ low-temperature seals prevent hydraulic fluid gelling and seal embrittlement in extreme cold; high-temperature seal upgrades for desert surface heat ensure year-round, all-weather smooth and reliable platform raising.
Maintenance-Free & Intelligent Monitoring
Self-lubricating composite bushings in both clevis or spherical bearings eliminate grease fittings and last through the equipment overhaul cycle. Optional integrated pressure and displacement sensors enable real-time load and height monitoring, supporting remote equipment health management.
