Overview
The telescopic crane is a highly efficient and flexible heavy-duty lifting equipment widely used in construction sites, logistics warehouses, ports, manufacturing, and large-scale equipment installation. Its core advantage lies in its telescopic structure design, which allows flexible adjustment of the boom length to adapt to lifting tasks of varying spans and heights, significantly improving operational efficiency and spatial adaptability.
Core Structural Components
Main Girder System
1. High-strength box-type or dual-girder structure with internal torsion-resistant ribs for enhanced rigidity.
2. Anti-corrosion coating extends service life to over 20 years.
Telescopic Boom
1.Multi-stage nested design driven by hydraulic cylinders, achieving a telescopic ratio of 1:3 for broad operational coverage.
2. Built-in limit switches and overload protection to prevent unauthorized overextension.
Lifting Mechanism
1. Wire rope hoist or electric chain hoist configurations with dual-speed/frequency conversion control, adjustable lifting speeds of 0.5–20 m/min.
2. Standard anti-sway technology reduces hook oscillation, ensuring precise operation.
Travel Mechanism
1. Rail-Mounted: Heavy-duty steel rails with gear-driven systems for high-frequency fixed-site operations.
2. Wheeled/Crawler: Independent steering systems for superior mobility in mobile tasks.
Safety Systems
1. Redundant safeguards: Overload limiter, emergency braking, wind speed monitoring, and lightning protection.
2. Real-time IoT-enabled data transmission for remote maintenance management.
