Mobile ramp with three-sided loading, 3SRM series (China)

Mobile yard ramps are specifically designed to provide ground to dock ramp access to high dock warehouses or trailer beds. They do not require special preparation to operate allowing for loading/unloading operations to be performed without construction of a traditional concrete ramp. All DoorHan ramps have a similar principle of operation, i.e. a ramp is lifted by a mechanical or hydraulic drive, equipped with safety system, and is easily transported to the warehouse dock or the trailer with a fork lift. If a ramp has legs then it is set on them, if the trailer bed is used as a support for the ramp then it is lowered onto it. After the loading/unloading operations have been completed the ramp is raised and transported to the place of storage. Mobile ramp with three-side loading allows servicing three trailers at a time.
Application:
  • Warehouses and Logistics Centres
Advantages
Provides easy access for a lift truck from the ground to the car body.
Possibility of direct transshipment of goods from one truck to another.
Ability to work with three trucks at the same time.
Execution with various types of drives makes it possible to use the ramp without power supply.

Don’t operate the ramp until its working zone is clear of people and goods.

Do not drive forklift on the ramp unless the lip is securely on the truck bed and has a minimum of 250 mm overlap on its surface.

Don’t overload the ramp. The permissible load corresponds to the total weight of the forklift with the load and the driver.

Don’t lift the mobile ramp with goods lying on it.

After the loading/unloading operations have been completed put the ramp into the stored position.

Don’t turn off the power from control unit during the whole loading/unloading cycle (for mobile ramps with hydraulic drive).

Don’t exceed the forklift speed (not more than 5 km/hour).

Don’t drive the forklift on the ramp until you are sure the lip is securely on the truck bed (for mobile ramps with hydraulic drive).

Make sure the WORK button is pressed, and the power switch of the control unit is ON during the whole loading/unloading cycle. Otherwise the hydraulic pump may be damaged (for mobile ramps with hydraulic drive).

Prior to operation take off the shipping fasteners. Attention! During loading/unloading operation the ramp with hydraulic drive and ramp with support on the trailer bed automatically follows the trailer bed height fluctuation. The ramp without support on the trailer bed has a lip which follows the truck bed movement (maximum deviation from the horizon is ±100 mm).

DoorHan mobile yard ramps can only be used with forklifts having inflatable wheels. Don’t drive hydraulic trolleys and loaders with polyurethane wheels having high point load onto the ramp.

Additional Information print

All the DoorHan products are loaded with hydraulic crane or fork-lift truck with 2 m long forks. Customer or installer is recommended to use similar equipment. When lifting with crane or other lifting device use slings of corresponding lifting capacity.

Warranty print

DoorHan warrants the three-side loading yard ramp to operate properly for a period of 1 year from purchase date for retail orders and for 2 years from purchase date for dealer orders.
