- Motor and Brake System: The hoist is powered by a motor, usually electric or hydraulic, depending on the crane’s design. A braking system ensures the load can be securely held in place during lifting or lowering.
Trolley System
The trolley is the part that moves horizontally along the main girder, carrying the hoisting mechanism. The movement of the trolley allows the crane to position the load accurately. The trolley system typically consists of:
- Trolley Frame: A robust frame that carries the hoist.
- Wheels: These are mounted on the trolley and run along tracks on the main girder to facilitate horizontal movement.
- Trolley Motor: Powers the horizontal movement of the trolley along the girder. Like the hoist, this is usually an electric motor equipped with a brake for accurate load positioning.
Rubber Tires and Steering System
- Rubber Tires: Typically, RTG wheeled gantry cranes have four, eight or more large, heavy-duty rubber tires designed to support the crane’s weight while providing smooth movement across different surfaces.
- Steering System: The rubber tire crane’s steering system allows the crane to maneuver in tight spaces. Depending on the rubber tyred gantry crane model, it can offer multiple steering modes as mentioned previously.
- Anti-Skid Design: The steering mechanism combined with anti-slip control ensures stable movement, even on uneven or slippery surfaces, contributing to safer crane travel.
Control System
The control systems ensure smooth, precise operation. They include:
- Cabin Control: The operator’s cabin is usually mounted high on the crane, offering a clear view of the working area.
- Remote Control System: Some rubber mounted gantry cranes are equipped with remote control systems, allowing operators to control the crane from a distance, improving safety and flexibility.
- Programmable Logic Controllers (PLC): The intelligent PLC-based control system automates crane functions and integrates with variable frequency drives (VFD) for smooth, efficient, and accurate load handling.
