  <h2>Überladebrücke Serie DLHH mit Klappkeil – Stationärer Höhenausgleich</h2>
  <p>Die elektrohydraulische Überladebrücke der Serie DLHH mit schwenkbarem Klappkeil dient dem Höhenausgleich zwischen stationärer Laderampe und LKW-Ladefläche. Das System wird elektrohydraulisch betätigt: Über Hydraulikzylinder hebt sich die Plattform an, woraufhin der Klappkeil ausschwenkt und auf der Ladefläche des Fahrzeugs abgelegt wird. Während des Verladens folgt die Brücke den vertikalen Federungsbewegungen des Lastkraftwagens.</p>
  <p>Die Serie DLHH ist als Kastenmodell ausgeführt und für den festen Einbau in eine vorbereitete Grube der Laderampe konzipiert. Der integrierte Tragrahmen nimmt die auftretenden Kräfte auf und sorgt für eine feste Verbindung mit dem Baukörper. Die Plattform und der Klappkeil bestehen aus rutschhemmendem Stahl-Tränenblech, was eine griffige Kontaktfläche für Flurförderzeuge bei wechselnden Witterungsverhältnissen gewährleistet.</p>
  <p>Die Bedienung erfolgt zentral über eine Steuereinheit, die den Hebe- und Senkvorgang per Knopfdruck steuert. Umlaufende Warnmarkierungen und seitliche Schutzbleche an den Rahmenkanten decken die Öffnungsspalte während des Betriebs ab.</p>

Advantages

Multipurpose Platform

This platform is a typical transfer dock solution for different buildings.

Immediate stop in case of an emergency

The hydraulic safety system stops the platform when a hose breaks or the machine leaves during operation.

Tilt behind the car body

When working with a vehicle with a skewed body, it is possible to tilt the platform to the side up to 100 mm.

Safety elements

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

Wide operation temperature range

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

Resistance to corrosion

Shot blasting of the metal before powder coating.

Side sealing between deck and frame

DCUH-1 control unit. Standard. 380V 3 phase power supply. Operates a dock leveler via a constant-pressure push-button. Returs the dock leveler to stored position via a constant-pressure push-button. Blocks the dock leveler when the door is closed.

DCUH-2 control unit. With advanced functions. 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.

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.

Photo electric 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 bay. 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 door vertical angle. Available in any diameter from 100 to 159 mm.

Traffic lights Traffic-light-LED. Help manage safe traffic of trucks and forklifts during departures/entries and loading operations. Can be connected to control units of DCUH-2, DCUH-3 series.

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 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.
