5Ton Omnidirectional Mobile Dock Leveler | Tobacco Industry Scissor Lift

Overview

Gradin’s specialized scissor lift solves height differentials between trucks and docks in tobacco logistics.

With a 5500×3000mm platform, 700mm ultra-low profile, and 5-ton payload capacity. Integrated steerable drive wheels and 4×10-ton hydraulic legs ensure millimeter-level positioning accuracy in outdoor environments.

Basic Parameters

Parameter	Value
Model	SJG4.5-0.8
Platform Size	5500×3000mm
Min Height	700mm
Max Lift	1500mm
Rated Load	4.5 Tons (5-ton tested)
Lifting Speed	2-3m/min
Drive System	2 Steerable + 2 Passive Wheels
Stabilizers	4×10-ton Hydraulic Legs
Control	Wireless Remote (E-stop)

The Challenge

Space Constraints: Limited dock area requiring agile movement
Precision Demands: ±3mm positioning accuracy for truck docking
Safety Risks: ≤5mm platform deformation under full load, zero vibration lifting
Harsh Conditions: Outdoor rainproofing, wheel durability requirements

Solutions

Structural Innovation

Corner-mounted wheel system (clearance for scissor mechanism)
6mm smooth steel platform (diamond plate prohibited)

Omnidirectional Mobility

2× steerable drive wheels + 2× heavy-duty casters (8-ton total)
Remote control: traverse/rotate/linear modes

Stability Assurance

Auto-deploying hydraulic legs lift wheels off-ground during operation
Wheel-integrated mechanical locks
