Electro-Hydraulic Dock Levelers with Hinged and Telescopic Lip
DoorHan electro-hydraulic dock levelers are engineered to create a smooth, safe, and stable bridge between the warehouse concrete loading dock and trailer beds of varying heights. Constructed from high-strength teardrop anti-slip steel deck plates supported by longitudinal I-beam structural ribs, our dock levelers effortlessly absorb the high dynamic forces generated by loaded 3-wheel and 4-wheel forklifts during intensive 24/7 freight handling.
Available in two primary configurations: the DLHH series with a hinged (swing) lip for standard commercial fleets, and the DSH series with an electro-hydraulic telescopic lip extending up to 1,000 mm with millimeter precision.
Key Technical Specifications & Engineering Standards:
- Dynamic Load Capacity: Rated for standard 60 kN (6 tonnes) dynamic load with optional heavy-duty packages up to 100 kN (10 tonnes) per European standard EN 1398.
- Dual Hydraulic Cylinder Geometry: Compact hydraulic power unit featuring twin main lift cylinders and a separate lip actuator cylinder for balanced, vibration-free platform positioning.
- Safety Velocity Fuses: Immediate hydraulic line rupture protection locks the platform in position if a truck pulls away prematurely during forklift loading.
- Torsion Deck Flexibility: Engineered platform flexibility compensates for up to 100 mm of lateral trailer tilt caused by uneven cargo weight distribution during loading.
- Versatile Sub-Frame Mounting: Available in pit-mount, box-mount, and suspended frame configurations for new construction or pit retrofits.
Quality Assurance & Engineering Compliance:
DoorHan dock loading systems, hydraulic levelers, and external dock houses comply strictly with European standard EN 1398 and CE Machinery Directive 2006/42/EC. Each leveler platform is factory proof-tested for dynamic point load capacities up to 100 kN with built-in emergency velocity fuses to prevent platform free-fall during unexpected truck departures. Full architectural pit installation drawings, civil foundation guides, and hydraulic line diagrams are available for engineering teams.
DoorHan dock levelers deliver bulletproof structural reliability, ensuring smooth material flow and eliminating equipment downtime across high-traffic freight terminals and intermodal logistics centers.
