RTG Rubber Tyred Gantry Crane

RTG rubber tire container gantry crane is employed to handle containers, large component at the loading/unloading places and container yard. This rubber tyred gantry crane is fitted with multiple hooking point's spreaders to meet the needs of different lifting situations. The whole crane can carry out 360° steering with flexible movement.

Rubber Tyred Gantry Crane is usually equipped with special container telescopic spreader, which can safely and efficiently handle 20ft, 40ft, 45ft containers.RTG integrates automation technology, such as automatic positioning system and anti-sway control system, which effectively improves the safety and efficiency of operation.

Rubber Tyred Gantry Crane can be divided into 2 types of diesel-electric and diesel-hydraulic, according to the driving method, and the differences are as follows:

Diesel-electric

It is powered by diesel-driven generators, electric motors drive the various mechanisms; with high energy utilization, frequency conversion speed regulation, easy maintenance, and suitable for the modern green port needs. It is characterized by high energy utilization, frequency control, easy maintenance, suitable for long-time continuous heavy load operation, and better environmental protection than pure diesel drive.

Diesel-hydraulic mode

It is driven by a diesel engine hydraulic pump, power transmission through the hydraulic system; has a compact structure, fast response, flexible layout, smooth starting and stopping, strong overload resistance, but lower efficiency, suitable for small and medium-sized or intermittent operation scenarios, maintenance complexity is higher.

Rubber Tyred Gantry Crane consists of gantry bracket, power transmission system, hoisting mechanism, traveling mechanism, trolley running mechanism, trolley running mechanism and special container spreader. The following are the functional characteristics of each component:

Portal Bracket

Heavy-duty steel structure frame to support the whole machine and provide working space, usually with box beam design, featuring high strength and good torsion resistance.

Power Transmission System

Mostly adopts diesel-electric hybrid or all-electric drive, equipped with frequency conversion control to realize efficient energy conversion and smooth speed regulation.

Lifting mechanism

It is composed of motor, reducer, reel, and wire rope, adopting a double or multiple reels design, supporting fast lifting and lowering of containers, equipped with load sensor and height limiter, providing accurate positioning and overload protection.

Traveling Mechanism

Tire-type design, equipped with a hydraulic or electric drive system, with a variety of steering modes, to adapt to the demand of flexible transfer in the yard, some models are equipped with an automatic deflection correction system.

Trolley running mechanism

It controls the longitudinal movement of the whole machine along the yard, adopts the structure of multi-wheeled balancing beam to disperse the wheel pressure and reduce the damage to the yard floor, and is equipped with anti-collision and anchoring devices.

Trolley running mechanism

Drive the spreader to move transversely along the main beam, adopting rack and pinion or steel wire rope traction mode, with a precise positioning system (such as laser distance measurement), the error of the spreader to the box is ≤±10mm.

Specialized container spreader

Equipped with a rotary locking device as standard, it can automatically or manually lock the corner pieces of containers, and supports the switching of various box types from 20ft to 45ft, and part of the spreader integrates the functions of weighing and tilt angle detection.

• Free movement: Due to the use of rubber tires, RTG gantry crane can move freely without laying tracks. It is not limited to fixed paths, and can more flexibly cope with complex operating environments.
• Cross-row capability: RTG rubber tyred gantry crane can cross multiple rows of containers without repositioning or changing positions, which improves operational efficiency.
• Independent operation: Each RTG is a complete unit that does not rely on additional infrastructure such as ground track systems, simplifying management.
• Easy maintenance: The tire drive mechanism is relatively simple, repair and maintenance are easier, downtime is short, and long-term operating costs are reduced.Space-saving: single main beam structure occupies little space, suitable for limited height of the plant or outdoor use scenarios.

• Covinicrane's RTG Rubber Tyred Gantry Crane is multi-functional and highly efficient, reducing container-handling time and enhancing overall operational efficiency in ports or logistics hubs, stable under heavy loads and reliable during long-term operation to minimize breakdown risks.
• They have an extensive operation range and remarkable maneuverability, being able to travel straight, laterally, make 0 - 90 degree turns, and turn in a place with ease to adapt to different container storage layouts and complex working environments, and are less affected by ground unevenness.
• Their operation is user-friendly with a simple interface for quick proficiency. Also, the maintenance is easy with accessible components and a clear procedure, reducing downtime and costs.

• Seaport & inland port container yard: Stacking & container transfer for shipping terminals (as shown in picture).
• Large logistics & container park: Container storage, loading/unloading for inland dry port, freight distribution center.
• Customs supervision yard & freight depot: Temporary container stacking, container truck loading operation for bonded warehouse.
