Handling oversized tunnel segments and welding them into structural pipe barrels introduces extreme tipping hazards and crane bottlenecks. This custom 20-ton 90-degree hydraulic pipe upender delivers a rigid, dual-platform cradle engineered to rotate Ø6.6m to Ø7.8m assembled pipe segments smoothly within 5 minutes.
Heavy-Duty Capacity: 20,000 kg rated payload engineered for continuous structural fabrication cycles.
Dual-Platform Architecture: 3000×4800 mm and 4800×7800 mm structural steel frames withstand asymmetric dynamic loads.
Integrated V-Cradle: Multi-radius bolt-locking interfaces accommodate Ø6.6m, Ø7.2m, and Ø7.7m pipe outer diameters.

The machine frame is fabricated from heavy-gauge J300×200×10 mm structural rectangular tubing, reinforced with 4 mm anti-skid carbon steel deck plates to withstand localized impact during segment positioning. Dual high-pressure hydraulic cylinders (bore/rod diameter Φ150/105 mm) utilize hard-chrome plated piston rods and polyurethane dual-lip seals, preventing internal pressure leakage under static loads up to 20 metric tons. All structural weldments undergo thermal stress relief and sandblasting to Sa 2.5 standard, finished with a heavy-duty PB11 peacock blue polyurethane topcoat resistant to industrial shop abrasion and outdoor environmental exposure.
Hydraulic circuit manifolds integrate pressure-compensated flow control valves and localized grease fittings on all high-load pivot bearings, enabling routine inspection without disassembling structural members. GRADIN provides a 12-month structural and hydraulic warranty, complete CAD/hydraulic schematics, and rapid dispatch of replacement seal kits and solenoid valves to minimize downtime during critical tunneling project timelines.
The 15kW electro-hydraulic power pack delivers synchronized lifting control through a centralized floor-mounted control console and a redundant handheld pendant station. Multi-position bolt-hole fixtures along the platform edge allow rapid changeover across Ø6.6m, Ø7.2m, and Ø7.7m pipe barrel diameters without external rigging tooling. The complete 90-degree tilting cycle is executed smoothly in under 5 minutes, maintaining a total vertical standing height within 8.9 meters to clear standard overhead crane limits.
Dual hydraulic pilot-operated check valves lock cylinder motion instantaneously in the event of power interruption or pressure decay. Mechanical hard stops, limit switch trip bars, and hydraulic counterbalance valves prevent over-rotation beyond 90 degrees. For adjacent component manufacturing solutions, facilities can deploy complementary heavy-duty mold upenders along their preparation line. The equipment strictly conforms to international industrial safety directives:
OSHA 1910 Standard for General Industry Machine Guarding and Hydraulic Power Safety
ASME B30 Safety Standards for Material Handling and Load Rotation Equipment
ISO 12100:2010 Machinery Safety – General Principles for Design and Risk Assessment
CE Machinery Directive 2006/42/EC compliance for heavy structural tilters

For this heavy-duty series, we can engineer load capacities up to [300] tons, with platform dimensions and lifting heights customized to your operational envelope. Requirements exceeding our standard engineering matrix will undergo a Finite Element Analysis (FEA) by our engineering team to ensure structural viability before proposing a solution.
To initiate the engineering proposal, please provide the following baseline data:
Rated Load Capacity
Maximum Lifting Height & Closed Height
Platform Dimensions (L x W)
Duty Cycle (e.g., operational cycles per hour/day)
Environmental Conditions (e.g., indoor/outdoor, washdown, explosion-proof)
Pit depth or overhead clearance constraints
Yes. The control systems can be equipped with standard communication protocols (e.g., Profinet, Modbus, Ethernet/IP) utilizing [Siemens / Allen-Bradley / Omron] PLCs. This ensures seamless I/O signal synchronization with upstream/downstream conveyors, AGV/AMR units, and your central control room.
Every custom unit undergoes a mandatory Factory Acceptance Test (FAT) prior to dispatch. This includes continuous operational testing at 100% rated load, static overload testing at [120% / 125%] capacity, and the physical triggering of all mechanical anti-fall and hydraulic safety interlocks. FAT documentation and video proof are included in your engineering package.
Upon final approval of the General Arrangement (GA) drawings, the manufacturing lead time is typically 4 to 8 weeks. Oversized structural components are engineered with a modular design to fit into standard shipping containers (20FT/40HQ). On-site assembly utilizes pre-engineered bolted flange connections and heavy-duty aviation plugs, strictly eliminating the need for field welding.
We provide a standard [12/24]-month warranty covering the structural frame and primary hydraulic/electrical components. To minimize operational downtime, a comprehensive set of standard consumables (e.g., cylinder seal kits, travel switches, relays) is shipped alongside your equipment. During the warranty period, replacement parts for non-human-induced failures are dispatched via priority air freight (DHL/FedEx) within 48 hours.
Beyond the warranty, we guarantee lifetime engineering support. Your custom equipment's CAD drawings, electrical schematics, and BOM (Bill of Materials) are permanently archived in our system. This ensures you receive uninterrupted remote troubleshooting, maintenance guidance, and exact spare parts matching for the entire lifecycle of the equipment.
