01 · Overview

Telescopic Dock Leveler at a Glance

The RAX Telescopic Dock Leveler is a pit-installed hydraulic leveling bridge with a sliding (telescopic) lip that extends directly onto the trailer floor, rather than hinging down onto it. The telescopic lip architecture is one of the two dominant EU pit-leveler designs alongside the hinged-lip variant [SOURCED] hoermann.cn. The sliding lip is preferred for cold-storage docks (it maintains the cold-chain seal by not breaking the insulation envelope), high-throughput positions and docks where trailers cannot reverse fully to the dock face.

Like the hinged-lip leveler, the telescopic variant uses a hydraulic power pack to raise the platform and a lip that extends onto the trailer floor — but the lip slides out (telescopes) rather than folding down. This allows full float to follow trailer bed movement during loading, with the lip remaining in continuous contact with the trailer floor. Market-typical capacity classes match the hinged-lip range: 6–12 tonnes on platforms of 2,000×2,000 mm or 2,500×2,000 mm [SOURCED] industry reference data. RAX manufactures each telescopic leveler to your pit dimensions and duty cycle — from prototype to full production runs, with pit-recess drawings.

Key Features & Benefits

Sliding Telescopic Lip

Lip extends (telescopes) out onto the trailer floor rather than hinging down — maintains continuous contact without breaking the dock seal or insulation envelope [SOURCED: hoermann.cn].

Cold-Storage Optimized

The telescopic lip does not penetrate the dock seal, making it the preferred leveler type for cold-storage and frozen-food docks where the insulation envelope must be maintained [ESTIMATE].

High-Throughput Rated

Smooth hydraulic operation with full float to follow trailer bed movement; ideal for distribution centers running 200+ cycles/day [ESTIMATE].

Same Capacity as Hinged-Lip

Market-typical 6–12 t capacity on 2,000×2,000 mm or 2,500×2,000 mm platforms [SOURCED: industry reference]; RAX confirms your rating from forklift data.

One-Button Hydraulic Operation

Push-button raise / lip-extend / lower sequence; automatic float follows trailer bed; optional interlock with dock door or vehicle restraint.

Install-Ready Package

English installation manual + pit drawings + wiring diagrams; power pack pre-wired and bench-tested; FOB Tianjin or Qingdao.

Sizing note: Telescopic-lip levelers are preferred for cold-storage and high-throughput docks. If your dock is ambient-temperature with standard trailer access, the hinged-lip Hydraulic Dock Leveler is more cost-effective. Send your dock layout and temperature requirement for a lip-type recommendation.

How to Specify (Buyer Guide)

1. Temperature Requirement

Cold-storage or ambient? Telescopic lip maintains the insulation envelope; hinged lip is cost-effective for ambient.

2. Forklift Fleet

Heaviest forklift model, rated load and typical carried load. This sets the leveler capacity class.

3. Dock & Trailer Heights

Dock height above yard, and trailer bed height range — defines the required working range.

4. Pit or No Pit

New build: send pit-recess civil drawings. Retrofit without a pit: see our Dock Lift or Adjustable Dock Plate.

05 · Customization

OEM / ODM & Customization

RAX supports full private-label production of the Telescopic Dock Leveler: custom platform sizing, RAL colors, branded control boxes, packaging printing and installation-manual translation (EN/ES/FR/AR/RU). Start with an OEM sample and scale to container-load branded production. Custom Tooling records are archived for up to 5 years — no extra tooling fee on repeat orders, all under strict NDA.

06 · Compliance

What is the difference between a telescopic-lip and hinged-lip leveler?

Both are standard EU pit-leveler architectures [SOURCED: hoermann.cn]. The hinged lip folds down onto the trailer bed; the telescopic lip slides out onto the trailer floor. Telescopic is preferred for cold-storage (maintains the seal) and high-throughput docks; hinged is more cost-effective for ambient docks.

Is the telescopic leveler suitable for cold-storage docks?

Yes. The telescopic lip extends through the dock seal opening onto the trailer floor without breaking the insulation envelope, making it the preferred leveler type for cold-chain and frozen-food docks [ESTIMATE].

What capacity telescopic leveler do I need?

Market-typical capacity is 6–12 tonnes on platforms of 2,000×2,000 mm or 2,500×2,000 mm [SOURCED: industry reference]. Capacity must cover your forklift’s dynamic axle load. Send your heaviest forklift model and we calculate the required rating.

Is the leveler CE-marked to EN 1398?

EN 1398:2009 is the harmonized EU standard for dock levellers [SOURCED: antpedia.com]. RAX’s held CE scope covers the door range (EN 13241 / EN 12453); leveler-specific EN 1398 documentation is confirmed per project at inquiry.
