Designed with four-point synchronized lifting and rubber-tyred travel, this rubber tyred gantry crane provides a lifting capacity of 20 tons at each lifting point and a total lifting capacity of 80 tons. It is suitable for the stable lifting, horizontal transfer, and precise positioning of large components. No fixed rails are required, allowing the crane to travel freely on prepared hard surfaces while combining heavy-duty lifting capacity with the mobility needed for demanding site conditions.

This project involves a 4×20 ton Rubber Tyred Gantry Crane featuring a multi-point synchronized lifting system and a total lifting capacity of 80 tons. The rubber tyred gantry crane is mainly used for lifting large components, short-distance transfer, and material handling within the working area.
Unlike conventional fixed rail-mounted lifting equipment, this crane uses a rubber-tyred travel system and does not require fixed rails to be installed in advance. Its travel route can be adjusted according to the actual requirements of the site. This makes it particularly suitable for construction sites, precast component yards, industrial logistics areas, and other projects where the equipment needs to move frequently between different work zones.
The crane adopts a “Π”-type gantry structure, with the crane trolley mounted on the main girder. The trolley allows the load to move horizontally, while the lifting mechanism provides precise vertical positioning. The four lifting points work together to maintain good stability when handling large, long, and heavy components.
This Rubber Tyred Gantry Crane is equipped with four 20-ton lifting points, providing a total lifting capacity of 80 tons. The multi-point synchronized lifting system coordinates the movement of each lifting mechanism according to the load condition, helping reduce tilting and swinging caused by uneven loading during the lifting of large components.
For steel structures, large precast components, machinery, and other heavy units, the synchronized lifting system allows the load to be lifted as a whole while maintaining stability during transfer.
The rubber tyred gantry crane features a stable “Π”-type gantry structure, providing a reliable load-bearing frame for the crane trolley and lifting mechanisms.
The transverse traveling trolley can move horizontally along the main girder, allowing the lifting position to be adjusted rather than being limited to a fixed lifting point. Combined with the travel capability of the rubber-tyred crane, the system can achieve multi-directional positioning through the coordinated movement of the complete crane, trolley, and hook. This helps improve the efficiency of lifting and positioning large components.
The rubber tyred gantry crane is equipped with large industrial rubber tires and can travel directly on prepared hard surfaces without the need for permanent rails.
The travel system supports 360° steering, crab steering, and lateral movement, allowing the operator to select the most suitable travel mode according to the available space. With a minimum turning radius of approximately 6–8 meters, the crane can turn and reposition itself even in relatively narrow construction areas.
For projects with several separate working zones, the equipment can be moved according to the construction schedule, reducing the limitations that fixed lifting equipment can place on site layout.
Large lifting equipment often requires considerable operating space, while actual construction sites do not always provide wide and regular working areas.
To address this challenge, the 4×20 ton Rubber Tyred Gantry Crane places particular emphasis on overall mobility. The crane can perform crab and lateral movements, allowing its position to be adjusted quickly by changing the travel direction in narrow passages, construction areas, and sites where multiple pieces of equipment are operating at the same time.
In restricted areas such as passages approximately 10 meters wide, the crane can make use of its relatively small turning radius to complete turning and repositioning operations, providing a more flexible solution for the on-site handling of large components.
When lifting large components, sufficient lifting capacity is only part of the requirement. Stable control of lifting speed, load conditions, and stopping operations is also important.
The equipment is fitted with a dual braking lifting system. In addition to the normal working brake, the additional braking arrangement provides further protection and helps improve load safety during suspension and positioning.
The lifting and travel systems also use Variable Frequency Drive (VFD) control. The operating speed can be adjusted according to actual working conditions, allowing smoother starting, acceleration, deceleration, and stopping while reducing the impact of sudden movements on the crane structure and suspended load.
The combination of synchronized multi-point control and VFD technology enables the crane to handle the precise lifting and transfer of large components more smoothly.
Traditional rail mounted gantry cranes require the rail foundation and travel route to be planned in advance. Once the working area changes, the usable range of the equipment may also be restricted.
The 4×20 ton Rubber Tyred Gantry Crane, on the other hand, uses a self-propelled rubber-tyred chassis and requires no fixed rails. As long as the working area provides a prepared surface with sufficient load-bearing capacity, the crane can move independently around the site.
This design is particularly suitable for projects with long construction periods, changing working areas, or frequent equipment relocation. The crane can be repositioned as construction progresses, reducing the impact of permanent foundations and rail infrastructure on the overall site layout.
The 4×20 ton Rubber Tyred Gantry Crane is designed for engineering projects that require both high lifting capacity and strong mobility. It can be widely used in the following applications:
The 4×20 ton Rubber Tyred Gantry Crane combines an 80-ton total lifting capacity, multi-point synchronized lifting, and highly mobile rubber-tyred travel in one piece of equipment. While meeting the requirements of heavy-duty lifting for large components, it also addresses the limitations of conventional fixed rail-mounted equipment in terms of site adaptability and relocation.
With no fixed rails required, multi-directional travel capability, a relatively small turning radius, VFD control, and a dual braking system, the crane provides smoother lifting and travel performance across a range of working environments, including construction sites, precast component yards, industrial manufacturing facilities, and logistics areas.
For projects that require large components to be lifted, transferred, and accurately positioned within limited working areas, this 4×20 ton Rubber Tyred Gantry Crane provides a heavy-duty lifting solution that combines load capacity, operating efficiency, mobility, and safety.
