Heavy-Duty Mobile Yard Ramps for Forklift Container Unloading

DoorHan mobile loading ramps provide a flexible, heavy-duty cargo handling bridge that allows forklifts to drive directly from ground level into the bed of a truck, trailer, or sea freight container. Ideal for logistics yards, temporary distribution depots, and industrial sites without dedicated raised concrete loading docks, mobile yard ramps enable fast, single-operator loading and unloading anywhere on the yard.

Featuring an integrated hydraulic height adjustment system (available with manual dual-speed hydraulic pump or electro-hydraulic power pack), DoorHan mobile ramps adjust effortlessly from 900 mm to 1,650 mm to match all commercial transport trailer heights.

Key Technical Specifications & Engineering Standards:

  • Heavy Load Capacities: Standard dynamic load capacities of 6 tonnes (60 kN), 8 tonnes (80 kN), and 10 tonnes (100 kN) dynamic forklift rating.
  • Anti-Slip Expanded Steel Grating: High-grip hot-dip galvanized steel mesh driving surface provides superior traction for forklift tires in all weather, allowing snow and dirt to fall through.
  • Dual-Speed Hydraulic Adjustment: Manual hydraulic pump allows quick height leveling by a single operator in under 2 minutes.
  • Safety Chains & Wheel Chocks: Heavy-duty forged steel safety chains lock the ramp securely to the truck chassis to prevent separation during vehicle loading.
  • Integrated Transport Wheels: Heavy-duty polyurethane wheels and tow bar attachment allow a single forklift to move and position the ramp across the logistics yard easily.

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 mobile yard ramps offer an immediate, versatile, and high-ROI solution for freight operators demanding flexible loading logistics.
