Telescopic Lip (HTL) Dock Leveller

Telescopic Lip (HTL) Dock Leveller

The hydraulic dock leveller with telescopic lip (700 mm or 1000 mm) is available as pit model, dock box model and hang-in frame model to allow easy configuration to suit your existing pit (e.g. replacement dock levellers) or newly constructed (prefabricated) concrete pit, it is ideal for refrigerated installations and side loading of vehicles. The durable platform is raised by two lifting cylinders with a build in velocity fuse to rapidly stop platform descent in case of an emergency. The microprocessor controls can be adjusted to meet your specific operating requirements. The safety features include return to dock position, velocity fuse free-fall protection, full range toe-guards with painted yellow/black warning stripes and a maintenance support strut.

Features & Benefits
• Micro-processor controls with return to dock position– allows easy adjustment to meet your specific operating requirements, standard equipped with return to dock position to enable safe fork-lift truck cross-traffic.
  • Durable platform construction– Box construction with welded support beams and anti-slip chequer plate.
  • Designed to compensate for canted truck beds– up to 100 mm and remains flush with the rear of the pit.
  • Telescopic lip– Standard design includes four maintenance free roller bearings to reduce friction. Standard lengths are 700 and 1000 mm. Tapered lip if nominal width is over 2000mm.
  • Smooth transition– Constant-radius rear hinge, two-point crown control on the front lip hinge, and an extended lip chamfer help provide the smoothest transitions for your operators, forklifts and products as they move in and out of a trailer.
  • Reliable hydraulic system– Automatic height adjustment. Two main lifting cylinders with build in velocity fuse (free-fall protection). Power pack is fitted to front of platform for easy maintenance.
  • Lip cylinder– The lip is extended with a double acting lip cylinder.
  • Maintenance support bolts– to support the platform and lip during service and maintenance.
  • Integral toe-guard– with painted yellow/black warning stripes.

The standard Telescopic Lip Dock Leveller employ two lengths of lip, 500mm and 1000mm enabling extended reach over tail lifts and with its precise control making it possible to unload vehicles with pallets right at the very back.
The HTL model is in full compliance with BS EN 1398.
The HTL Telescopic Dock Levellers are designed in 3 installation styles to suit your loading bay.

Traditional pit mounting: Where the pit is bounded with previously cast-in pit edge angles and the dock leveller sits on a solid pit base, the dock leveller is welded in at the back and front.
Suspended versions: Are available usually for new build projects or to replace existing suspended dock levellers. As their name suggests the dock leveller is suspended from its top edge allowing the underside of the pit to be clear for access by tail lifts; this enables the dock leveller clear access into the deck of the vehicle.
Box style: Dock levellers are designed to provide quick and easy installation in existing buildings. To install a box leveller an oversize pit is required complete with a flat base, the box model leveller is positioned and fixed down and concrete poured around it. Once the electrics are connected the leveller is ready to go.

Operation: The Platform rise button is held depressed; the platform can rise to the top of its range, and then by pressing the lip extend button and the lip will move forward to the desired loading position, by then pressing the platform lower button the lip will descend onto the bed of the vehicle. As standard the HTL telescopic lip dock leveller comes with an auto-park function, by pressing this button the platform will rise and the lip retracts fully, the platform then lowers itself back to the cross traffic position to complete the loading process.

Finish: Galvanising is an effective treatment to ensure a durable anti-corrosion protection. Especially in the food industry the application of a hot dip galvanised dock-leveller is preferred. The life span of a zinc coating can vary between 10 to 50 years, all depending on the atmosphere to which the galvanised steel is exposed. After the galvanising process, the dock levellers are primed and painted in the standard colour Black RAL 9005. It is possible to supply the dock-leveller in any other (non-metallic) desired colour. A non-slip paint is available as a platform finish.

Typical Applications
• Pharmaceutical Industries
• Food Processing Plants
• Chilled Distribution
• Warehousing
• Heavy Industry
Dimensions & Ranges
Our HTL models range from 2000mm to 3500mm overall width. The length is dependent on the vehicle and dock height with a gradient of no more than 12.5% during loading/unloading, lengths range from 2000mm to 5000mm rising in 500mm increments. Box style depths range from 595mm to 895mm depending on installation and pit type.
Depending on the dock-leveller length it is possible to achieve a max loading height of 750mm above FFL and a minimum of -690mm below FFL, with our vast range of dock-levellers there is a suitable option for any application.

Our dock-levellers are manufactured and to be used in accordance with BS EN 1398
Standard capacity 60 kN
Maximum gradient of the platform 12,5 %
Minimum contact area per wheel of 150 x 150 mm on the platform
Maximum driving speed lengthways 7 km/h
