XQV Synchronous Lifting Jack – Hydraulic Synchronous Jacking System for Heavy Lifting
Multi‑Point Synchronous Lifting with High Precision & Real‑Time Load Monitoring
- Synchronous lifting jacks (multi‑unit): High‑strength steel strand jacks with built‑in displacement sensors.
- High‑pressure hydraulic pump station: Variable frequency control for precise oil flow regulation.
- PLC central control unit: Real‑time data acquisition and logic control.
- High‑precision displacement & pressure sensors: Accurate feedback of lifting stroke and load.
- Steel strands & distribution manifold blocks: Force transmission and synchronous distribution.
🎯 High Synchronization Accuracy
PLC closed‑loop control ensures multi‑jack displacement error ≤±1 mm, ideal for precision positioning of large components.📈 Unlimited Stroke Capability
The steel strand system allows unlimited lifting height by repeated clamping and unclamping, breaking the limitation of traditional jack stroke.⚖️ Load Monitoring & Overload Protection
Real‑time monitoring of each jack’s load; automatic pressure regulation to prevent uneven lifting or overload.🖥️ Remote Control & Data Logging
Touch‑screen interface on the pump station, with optional wireless remote control and full data recording for traceability.🛡️ Fail‑Safe Safety Design
