Product Description

20t Lifting Machine Trackless Portable Mobile Rubber Tires Gantry Crane for Material Handling

The rubber-tired gantry crane (RTG) is a type of gantry crane that uses a tire-based traveling mechanism instead of traditional fixed rails. With its excellent mobility, flexibility, and operational efficiency, it has become a key equipment for material lifting in modern logistics systems.

Its core features include:

• The tire chassis design allows it to operate without fixed rails, enabling free movement, flexible steering.
• The optimized body structure, combined with a reasonable counterweight system, ensures stability when lifting heavy loads.
• Some advanced models are integrated with intelligent control systems, supporting remote operation or automated operation.

Rubber-tired gantry cranes are mainly used for cargo loading and handling in warehouses, ports, steel plants, power stations, bridge construction sites, shipyards, and other venues.

(2)Advantages & Limitations

Advantages	Strong Site Adaptability: Eliminates fixed rails, moves freely across yard zones, maximizing space utilization.
	Independent Operation: Performs stacking, loading, and unloading autonomously. No supporting equipment needed.
	High Transfer Efficiency: Swift zone-to-zone transfer. Accelerates response to operational commands.
	Stable Structure: Counterweight system and rigid gantry balance hoisting forces, ensuring heavy-load stability.
	Lower Initial Investment: No dedicated tracks required vs. RMGs. Reduces civil works and infrastructure costs.
Limitations	Stringent Ground Requirements: Demands extremely high ground flatness and load-bearing capacity in workshop.
	Frequent Maintenance: Tires is wear-prone walking components, require regular replacement.

(3)Product Structure 

Gantry Structure

1. Composition
   • Main beam: Constructed from I-beam or U-steel.
   • Legs and cross beams: Welded from Q235B or Q355B steel.
2. Functions
   • Supports the entire crane structure.
   • Transmits loads during operation.
   • Connects to the rails for stable movement.
3. Structural Feature
   • One side of the legs is directly supported on the ground.
   • The other side is fixed to the building via brackets or corbels, forming a semi-gantry configuration.

Lifting Mechanism

1. Composition
   • Primarily includes an electric hoist, which contains a motor, reducer, and steel wire rope/chain.
2. Function
   • Drives the vertical lifting and lowering of materials via the motor.
   • Serves as the core execution component for completing handling operations.

Electrical system

1. Composition
   • Includes motors, reducers, brakes, and control boxes.
2. Function
   • Precisely controls lifting and moving actions to ensure operational safety.
3. Advantages
   • High intelligence level for automated operation.
   • Strong protection performance against electrical faults and environmental factors.
   • Convenient maintenance for reduced downtime and cost.

Solid Tires

1. Application Scenarios
   • Outdoor harsh road conditions or heavy-load scenarios with gravel and sharp objects on the road, such as construction sites and mining yards.
2. Core Features
   • Non-pneumatic structure: Resistant to punctures and crushing, avoiding tire blowout risks caused by gravel and sharp objects.
   • Maintenance-free: No need for inflation or tire patching; offers strong stability and a longer service life than pneumatic tires.
   • Hard material: Mostly rubber or composite materials. Better load-bearing capacity than polyurethane tires, but higher operating noise.

Safety Devices

1. Rubber buffer: Absorbs impact energy to avoid rigid collisions.
2. Audio-visual alarm: Emits light and sound warnings during startup or abnormal conditions.
3. Overload protector: Monitors lifting weight and cuts off power when overloaded.
4. Contactor: Controls circuit on/off for crane operation and provides under-voltage/voltage-loss protection.
5. Circuit breaker: Automatically trips to cut off power during overload, short-circuit, or under-voltage faults.
6. Seamless slide wire: Ensures stable power supply with enclosed design.

(4)Purchase Recommendations
