Key Features and Benefits
Lightweight and Highly Maneuverable: The aluminum main structure significantly reduces dead weight, allowing a single operator to easily move and reposition the lift—perfect for fast job-site changes.
Precision Mast Guide Rollers for Smooth, Reliable Lifting: Specially designed guide rollers between the masts minimize sway during operation, ensuring a stable platform and greater operator confidence.
Compact Footprint for Superior Access: The transport dimensions are small enough to fit inside standard elevator cars and navigate through regular doorways and narrow access systems, making it ideal for finished indoor spaces.
Double-Protection Outriggers for Enhanced Safety: The outrigger system provides dual safety protection, allowing the lift to be positioned close to the work surface for secure and stable operation.
Optional Manual or Electric Telescoping Masts: Depending on the entry height at your site, the lift can be customized with either manual or electric mast-telescoping mechanisms, solving the challenge of low doorways.
Working Principle
The SJYL series twin-mast lift operates on an electro-hydraulic drive principle. An electric motor drives the hydraulic pump station to generate high-pressure oil, which is delivered through the hydraulic pipeline to the hydraulic cylinders within the twin masts. This pressure extends the mast sections sequentially, raising the work platform smoothly. For lowering, the Solenoid Directional Valve opens the oil return circuit, allowing hydraulic oil to flow back to the oil tank under gravity, resulting in a controlled and uniform descent.
Precision guide rollers between the mast sections maintain Coaxiality and Perpendicularity during telescoping, preventing jamming or swaying caused by uneven loads. Dual operation panels—one on the platform and one at ground level—give the operator flexible control from either position.
Structural Composition
The lift is composed of the following core structural components:
Twin-Mast Aluminum Column Structure: Constructed from high-strength aluminum alloy profiles in a multi-section nested design, with an anodized surface finish for corrosion resistance and reduced weight. Guide rollers between the masts ensure smooth telescoping action.
Hydraulic Lifting System: Comprising the Hydraulic Pump Station, Hydraulic Cylinder, Solenoid Directional Valve, hydraulic hoses, and oil tank, this system delivers stable lifting power with uniform, controllable ascent speed.
Work Platform: A welded platform made of anti-slip checkered steel plate, equipped with guardrails and a toe board around the perimeter for safe work at height. Platform dimensions are 1.35 × 0.6 m or 1.47 × 0.6 m depending on the model.
Chassis and Outrigger Mechanism: A steel chassis supports the entire structure, with adjustable outriggers at all four corners providing double safety protection. The chassis is fitted with swivel casters and fixed wheels for easy movement and precise positioning.
Electrical Control System: Dual operation panels (platform and ground) feature lift/lower buttons, an Emergency stop switch, and a power indicator light. The system supports dual voltage supply (220V/380V) for simple and safe operation.
