HSCT Series Multi-Stage Telescopic Cylinders
Engineering Overview & Structural Features
The HSCT Series Single-Acting Multi-Stage Telescopic Cylinders are engineered specifically for precision lifting in extremely confined overhead clearances where minimal collapsed height and extended cumulative stroke are critically required. Operating at 700 Bar (10,000 PSI) working pressure with rated capacities from 10 to 50 Metric Tons, the multi-tier telescopic plunger design maximizes effective lift height (up to 64 mm) from a collapsed profile as low as 42 mm, eliminating repetitive manual shimming, packing, and multi-step cribbing operations.
MULTI-STAGE TELESCOPIC EXTENSION
Sequential multi-tier plunger architecture substantially multiplies effective stroke without increasing body height, enabling long-travel lifting in narrow apertures and eliminating hazardous progressive cribbing.
ULTRA-LOW FLAT BODY GEOMETRY
Ultra-compact flat profile starting at just 42 mm closed height and 1.5 kg total weight provides seamless insertion into restricted machinery gaps, turbine baseplates, and bridge expansion joints.
SPECIALIZED SURFACE HARDENING
Cylinder body and telescopic pistons undergo proprietary surface conversion treatment, offering superior abrasion resistance, corrosion protection, and endurance against aggressive jobsite contaminants.
HIGH-FLOW COUPLER & SPRING RETURN
Standard single-acting spring-return mechanism ensures positive and rapid plunger retraction, paired with an industry-standard quick-connect hydraulic coupler and aluminum dust sealing cap.
Dimension codes (A: Collapsed Height, B: Extended Height, D: Outside Diameter) correspond directly to the Engineering Specifications table below.
OEM Cross-Reference & Dimensional Interchangeability
Single-acting spring-return multi-stage telescopic flat hydraulic cylinders rated for 700 Bar (10,000 PSI), engineered for extended stroke lifting in extremely confined overhead clearances without repetitive shimming across 10 to 50 Metric Ton capacities. 10 - 50 Ton / 25 - 64 mm Multi-Stage.

Which models are available in the HSCT series?
The specification table lists 4 models: HSCT-100, HSCT-200, HSCT-300, HSCT-500. For non-standard requirements, please describe them in the inquiry form.
Q4How is the HSCT tested before shipping?
expand_more
How is the HSCT tested before shipping?
Each unit is tested at 125% of its rated pressure before shipping (700 Bar rated, 875 Bar test pressure). This is above the 100% rated-load test required by ASME B30.1.
Q5What are the lead time, warranty and shipping options for the HSCT?
expand_more
What are the lead time, warranty and shipping options for the HSCT?
Lead time is typically 2–3 business days when the model is in stock and 7–35 business days otherwise. Warranty is 12 months after receipt of goods. Shipping is available by sea freight, air freight or international express (DHL, FedEx, UPS). Send your requirements through the inquiry form for an exact quotation and delivery date.
