Dual-Scissor Synchronized Lifting System: Solving Heavy-Duty Industrial Assembly Challenges with Millimeter-Level Precision

Project Overview

Customized for industrial manufacturing/assembly, this dual-scissor synchronous lifting platform raises 3000kg loads to 4m height via synchronized hydraulics, replacing manual handling and boosting efficiency/safety.

Basic Parameters

Product Model	SJG3.0-4.0
Lifting Platform Size	2000*750mm
Space Required Size	2100*850mm
Stroke Height	4000mm
Rated Load	3000kg
Equipment Self-Height	800mm (includes wheel height, four universal wheels)
Lifting Speed	2-3m/min
Overall Painting	Yellow + Black
Structure	Two Scissor Forks + Synchronous Motor + Hydraulic Pump Station + Control System
Scissor Fork Structure	Single Span, Three Layers

The Challenge

Synchronization Accuracy: Dual scissor arms must lift synchronously (deviation ≤2mm) to prevent load tilt or hydraulic overload.
Safety Compliance: CE certification requiring FMEA reports and 150% overload tests.
Compact Integration: Housing hydraulic and control units within 2100×850mm footprint (800mm self-height with casters).

Solutions

Closed-Loop Hydraulics: Synchronous flow divider + displacement sensors achieve <1.5mm deviation.
Safety Redundancy: Balance valves + mechanical locks for power failure safety; 120% load tested with SGS reports.
Space Optimization: Hydraulic/control units embedded in scissor base with cooling ducts for 40℃ environments

Advantages

✅ Sub-2mm Sync: Ensures load stability and extends lifespan.
✅ Full Compliance: CE-certified with test reports for global clients.
✅ Labor-Saving: 2-3m/min speed reduces 3 labor-hours per cycle, cutting timelines by 30%.
✅ Space-Smart: Casters + low profile fit tight spaces.
✅ Heavy-Duty: Manganese steel + chrome-plated rods for 100k cycles over 10 years.
