Engineered A-Shape Lattice Gin Pole for Heavy Load Lifting
Features:
The A-Shape Lattice Gin Pole is a heavy-duty lifting system specifically engineered for transmission tower erection, maintenance, and high-voltage line installation. Its distinctive A-frame design provides superior stability and load-bearing capacity compared to single-pole systems. Key features include:
High-Strength Construction: Available in galvanized steel or lightweight aluminum with corrosion-resistant coatings
Modular Lattice Design: Interlocking sections allow quick assembly and height adjustment (typically 6m to 25m)
Wide Base Stability: A-frame configuration prevents tipping during heavy lifts
Integrated Rigging Points: Multiple attachment points for precise load control
Safety Locking Mechanisms: Automatic pawl systems prevent accidental release
Optional Accessories: Including load cells, guy wire kits, and rotation systems
Working Principle:
The A-frame base is secured to the tower foundation or supporting structure
Guy wires (when used) provide additional lateral stability
A hoisting mechanism (manual chain hoist or powered winch) is mounted at the apex
The load is lifted vertically between the two legs of the A-frame
Guiding rollers ensure smooth operation and prevent load swing
Applications:
Transmission tower erection and component installation
High-voltage conductor stringing operations
Substation equipment lifting and placement
Cell tower antenna installation
Bridge cable installation projects
Advantages:
✔ Superior Stability - A-frame design resists side loads and wind forces
✔ Higher Load Capacity - Typically 1.5-2x capacity of single-pole systems
✔ Precision Control - Excellent for aligning heavy tower components
✔ Adaptable Configuration - Modular design suits various project needs
Service & Support:
Site-specific engineering calculations available
Custom fabrication for special applications
Complete inspection and maintenance manuals
Explain:
The head part of the Gin Poles is inverted,and the base part of gin pole is semicircle or square.And it should be noted when ordering.
03361-03445 is aluminum alloy material.03611-03615 is manganese steel material.
