Cantilever type dock leveler with rotary lip, DLHHC series

The electro-hydraulic platform with a cantilever-type rotating ramp of the DLHHC series is a typical device for loading dock equipment and is used to provide access from the warehouse area to the vehicle body. When launched, the platform rises and the ramp rotates and opens. The platform is lowered until it reaches the floor of the car body. Upon completion of work, the platform returns to its original position.

Advantages

Can be installed in pits of both closed and open type.

The hydraulic safety system will instantly stop the platform if a hose rupture or unauthorized departure of the truck during operation occurs.

Transport height - 400 mm.

Side curtain airbags prevent personnel feet from getting into the gap between the platform and the pit during operation.

Availability of specialized "winter packages" for use in areas with extremely low temperatures.

Shot blasting of the metal before powder coating.

DCUH-3 control unit. Complex control panel which operates various combinations of loading dock equipment. 380V 3 phase power supply. Operates the dock leveler via a constant-pressure push-button. Returns the dock leveler to stored position via one pressure of AUTO button. Blocks the dock leveler when the door is closed. Can be connected to indoor and outdoor traffic lights. Lights at platform area. Maintenance service indicator. Digital display. Controls overhead door operator. Controls inflatable dock shelter.

Photoeye sensor. Interlocks the dock leveler and sectional doors. The sensor blocks the dock leveler control when the door is closed to prevent its damage.

Wheel guides. They are used to direct reversing vehicles safely and quickly on to the loading docks thus preventing damages to dock shelters or the building. The guides are designed to minimise possible contact with the truck wheel rim. They are made of steel tubes with 159 mm diameter and positioned in front of the loading dock. These wheel guides are fixed to the surface with anchor bolts or embedded into a concrete foundation.

Safety fences. Fences are placed inside the premise to protect the walls from collisions with forklifts, ensuring correct and safe movement of the vehicle inside the premises and near the loading dock. Fences are made of steel tubes of 100–159 mm diameter, may have any design and be manufactured in accordance with customer’s orders.

Shock columns. Designed to prevent forklifts from damaging vertical angles of sectional doors used in loading docks. Shock columns are installed inside the premise in front of the doors vertical angle. Available in any diameter from 100 to 159 mm.

Traffic-light-LED to provide safe entering and exiting of the facility.

Standard lip 400 mm. 35 mm bevel. Whole rectangular lip for trucks with one-size load bed.

Wedge-shaped lip. 35 mm bevel. Whole, without segments. Such levelers are ideal for trucks with different-size load beds or in case a truck parks not in the center of the loading dock preventing truck damage.

Segmented leveler. 35 mm bevel. Has three segments. Folding of one or two side segments allows using the leveler with trucks whose load bed is narrower than the standard one. Applicable only with 6 000 kg capacity levelers.

Lip without bend. 35 mm bevel. Whole, without segments. Rectangular lip ideal for trucks with one-size load bed and loaders with low or very low clearance.

Conduct routine inspections and maintenance of the dock leveler to ensure its safe and smooth operation.

Keep people and goods clear of working area while operating the dock leveler.

Keep overhead door fully open while operating the dock leveler.

Make sure the vehicle is properly parked against the dock bumpers. Chock the wheels if needed.

Do not drive on the leveler unless the lip is securely positioned on the truck bed and has a minimum of 100 mm overlap on its surface.

Ensure that the control unit location allows the operator to clearly see and control dock leveler operation.

Use dock levelers with 1,3 Н/mm² point load only with standard forklifts having inflatable wheels.

Use dock levelers with 6,5 Н/mm² point load with loading machinery having high point load, including electric stackers, pallet carriers, reach trucks, order picking stackers on polyurethane wheels.
