Blue Adjustable Height Hydraulic Truck Dock Leveler

Product Description:

The Hydraulic Dock Leveler is a heavy-duty, high-performance loading dock solution designed to streamline warehouse operations. Featuring a robust steel construction and hydraulic-powered lifting (+400mm/-300mm stroke), it ensures smooth, precise alignment with trucks for efficient loading/unloading. Customizable voltage (380V or other) and frequency (50Hz/60Hz) make it adaptable to global standards, while its 495mm anti-slip lip plate and 8T–20T load capacity guarantee safety under heavy use. With push-button controls, pit or surface mounting options, and 1-year warranty, this dock leveler combines durability, flexibility, and ease of operation—ideal for logistics centers, warehouses, and industrial facilities seeking reliable, long-term material handling efficiency.

Here’s a highly detailed technical breakdown of the Hydraulic Dock Leveler in English, covering specifications, installation, maintenance, and customization options:

1. Core Structure & Working Principle

Key Components

• Hydraulic System

  • Cylinder: High-strength steel, pressure-resistant (≥20MPa), ensures smooth lifting.

  • Power Unit: Motor (2.2–4kW, customizable), with overload relief valve.

• Lip Plate

  • Dimensions: 495mm (length) × 0.5" (thickness), anti-slip steel with diamond tread or coated surface.

  • Hinge Mechanism: Spring/hydraulic auto-return for tight truck sealing.

• Control Panel

  • IP Rating: IP65 (water/dust-proof).

  • Buttons: Up/down/emergency stop; optional remote control (30m range).

Operation Flow

1. Docking: Lip extends to bridge the gap between dock and truck.

2. Leveling: Hydraulic adjustment (±10mm precision) to match truck bed height.

3. Loading: Forklifts/pallets move safely with even weight distribution.

2. Technical Parameters (Deep Dive)

3. Installation & Commissioning

Pre-Installation

• Foundation: Concrete ≥200mm thick (C30 grade), anchor bolts pre-positioned (tolerance ≤5mm).

• Electricals: Dedicated circuit breaker (32A recommended), grounding resistance ≤4Ω.

Step-by-Step Installation

1. Pit Prep: Verify dimensions (W1870×D500×H2280mm), clear debris.

2. Positioning: Use forklift/crane to place leveler, check levelness (≤2mm/m deviation).

3. Final Fixing: Bolt down, connect hydraulic hoses/power (ensure correct phase sequence).

Testing

• No-load Test: Cycle 3–5 times to purge air from hydraulics.

• Load Test: Verify with weights (8T–20T); deflection ≤1/500 of span.

4. Maintenance & Troubleshooting

Routine Care

• Weekly: Check hydraulic oil level (ISO VG46), lubricate chains (lithium grease).

• Monthly: Clean guide rails, tighten bolts (torque ≥50N·m).

Common Issues

5. Customization & Selection Guide

Key Considerations

• Load: Light (<8T) = mechanical; heavy (>15T) = reinforced cylinder.

• Frequency: High-use (>200 cycles/day) → add oil cooler.

• Environment: Cold climates → low-temp hydraulic oil (-40°C).

Optional Features

• Safety: LED warning lights, guardrails.

• Integration: Weighing system (±1% accuracy), PLC automation.

• Dimensions: Lip extendable to 600mm (wide trucks) or narrowed to 1500mm.

6. Advanced Applications

• Cold Storage: Stainless steel construction + anti-freeze oil.

• Smart Warehouses: PLC + WMS compatibility (RS485/Modbus).

• Hazardous Zones: Explosion-proof motor (ATEX certification).
