10-Ton Four-Link Scissor Lift Platform for Shipbuilding Industry

Overview

Client Background

A leading marine equipment manufacturer with 60+ years of experience, specializing in custom heavy-duty industrial equipment for shipbuilding.

Client Pain Points

Multi-ton components require precise height adjustment during crane positioning. Standard scissor lifts lack the torsional rigidity for eccentric loads. Operators must work close to the platform during coordination, creating safety risks. Floor space is limited and cannot be blocked.

Application

Installed in a pit, the platform sits flush with the floor when retracted. After crane placement, operators fine-tune height remotely to align components precisely. When idle, the platform resets flat — efficient, safe, and unobtrusive.

Solutions

1. Four-Link Scissor Mechanism — Engineered for Heavy Eccentric Loads

Unlike standard single-scissor configurations, this platform employs a four-link scissor mechanism with 250×100×6mm rectangular tube arms, delivering exceptional rigidity against both bending and torsion. The structure simultaneously handles 10-ton vertical loading and 4-ton lateral force along the platform’s length axis — directly addressing the unavoidable eccentric load conditions encountered during heavy marine component positioning and transfer.

2. Deep-Stroke Pit Installation — Zero Floor Obstruction

With a 3,200mm stroke and only 1,050mm collapsed height, the platform sits flush with the workshop floor when retracted. Heavy components can be loaded at ground level with no threshold barriers, a critical requirement in shipyard environments where large-scale components are moved by crane or forklift and floor clearance is essential.

3. Dual-Mode Local/Remote Control

The control system features seamless switching between local panel and remote operation. Remote inputs use industrial passive contact signals (pump start/stop, up/down commands, emergency stop), allowing operators to control the platform from a safe distance — particularly important when coordinating with overhead cranes or positioning large components.

4. Multi-Level Safety Protection

Automatic anti-runaway hold when hydraulic or power failure occurs; controlled descent allowed
Auto-hold at current position when payload exceeds 1 ton during unloaded ascent
Red non-self-reset E-stop for instant full power cutoff
Comprehensive motor protection: overheat, overload, and phase-loss

5. Low-Noise Power Unit

The hydraulic power unit incorporates dedicated noise reduction measures across motor/pump mounting, pipework routing, oil tank, and base frame design — ensuring the platform meets the strict noise control requirements of precision manufacturing environments.
