Lifting extra-long industrial pipelines and heavy structural steel beams requires dual-point elevation to prevent bending deflection and hazardous shifting. This non-standard custom heavy-duty synchronized dual scissor lift platform utilizes a centralized hydraulic pump station and flow-divider synchronous motor to drive twin 3-tier scissor tables in unison across a 4-meter elevation stroke.
Synchronized Tandem Lifting: Dual 3000kg scissor tables delivering 6000kg combined payload capacity.
4-Meter High-Reach Elevation: 3-tier scissor geometry providing 2-3m/min smooth lifting speed.
Jobsite Mobility & Leveling: Four heavy-duty swivel casters combined with mechanical screw outriggers per unit.

Engineered for demanding industrial pipeline installation, each scissor unit features heavy-duty solid steel plate pantograph arms linked by precision-machined pivot pins. The twin platform decks (2000*750mm each) provide stable two-point support for pipe bundles up to 12 meters in length. Lifting is powered by a central hydraulic unit incorporating a mechanical rotary gear flow divider, delivering equalized hydraulic volume to both dual-cylinder sets regardless of load distribution. Platforms feature an 800mm collapsed height, heavy-duty swivel casters with directional locks, and adjustable screw leveling jacks. Coated in industrial high-visibility yellow and black polyurethane finish. Structural design complies with OSHA workplace walking-working surface standards.
Designed for rapid field deployment and minimal downtime, all scissor scissor pivots and cylinder clevis joints incorporate grease zerks for routine lubrication. The centralized hydraulic power unit features quick-connect hydraulic couplings for fast jobsite teardown. Delixi electrical components inside the IP55 control enclosure include phase-loss protection and thermal motor overloads. Includes a 12-month structural and hydraulic warranty supported by comprehensive PDF/DWG technical drawings and testing documentation.
Operation is controlled through a handheld wired push-button remote box with an integrated emergency stop button. A single operator effortlessly controls both scissor lifts simultaneously with synchronous rising and lowering at 2-3m/min, eliminating the coordination errors associated with manual dual-crane lifting. Four caster wheels allow workers to roll each unit into position before deploying the screw outriggers, as demonstrated in Heavy-Duty & Sync Lifts .
Safety architecture strictly follows international ANSI/ASME scissor lift compliance protocols .
Mechanical Hydraulic Flow Synchronization: Rotary gear flow divider ensures equalized cylinder extension to prevent pipeline roll-off.
Cylinder Velocity Fuse Valves: Internal explosion-proof check valves lock hydraulic fluid instantly if pressure hoses rupture.
Mechanical Leveling Screw Jacks: Four adjustable screw outriggers on each chassis lock the lifts firmly against floor roll.
Hydraulic Pressure Relief Valves: Built-in bypass valves prevent lifting if total load exceeds the 6000kg rated limit.
Phase-Loss Protective Circuitry: Control panel automatically shuts down motor power if line phases are lost.
High-Altitude Industrial Pipe Installation: Elevating 6 to 12-meter chemical, steam, and gas pipelines for overhead flange fitting and hanger welding.
Structural Steel Beam & Truss Erection: Synchronously elevating heavy H-beams and architectural trusses to ceiling assembly elevations.
HVAC Ductwork Installation: Lifting long commercial air duct assemblies into ceiling grids in large warehouse projects.
Shipbuilding Long-Shaft Staging: Positioning marine propeller shafts and long hydraulic conduits inside shipyard workshops, as seen in Ergonomic Assembly Tables .
Clean Energy Pipeline Infrastructure: Synchronously elevating district heating pipes and hydrogen transit piping during plant construction.
Aerospace Long Tooling Staging: Synchronously supporting long composite tooling spars and rocket fuselage test sections.
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.
