رافعة جسرية كهربائية بإطارات مطاطية

An Electric Hoist Rubber Tyred Gantry Crane is a mobile lifting system that pairs a rubber-tyred gantry structure with an electric hoist. This equipment has a lifting capacity ranging from 1 to 50 tons and a span of up to 35 meters. It is commonly used in precast concrete plants, steel structure manufacturing workshops, and steel yards.

What is an Electric Hoist Rubber Tyred Gantry Crane?

This equipment is a lifting device that utilizes a rubber-tired travel mechanism. Its hoisting mechanism is equipped with an رافعة كبل كهربائية or chain hoist, with a rated lifting capacity of 1 to 50 tons and a duty class ranging from M3 to M6. Unlike container rubber-tired gantry cranes (RTG cranes), which are specifically designed for continuous stacking operations, this model is primarily used for general industrial lifting operations in precast concrete plants, steel structure manufacturing workshops, and various storage yards. Because its gantry legs use rubber tires rather than fixed rails, operators can flexibly reposition the crane within the site without the need to lay tracks, thereby saving on track installation costs.

Types of Electric Hoist RTG Crane

This RTG crane, which uses an electric hoist as its lifting mechanism, is available in both single-girder and double-girder configurations, which differ in lifting capacity and main girder design.

Single Girder Rubber Tyred Gantry Crane

Double Beam RTG Crane

Single Girder Rubber Tyred Gantry Crane: The single-girder type typically handles 1 to 20 tons using one box-girder bridge on two rubber-tyred legs. Depending on the required clear height and working class, users can choose to configure either a CD/MD-type wire rope electric hoist or a European electric hoist as the lifting system.

Double Beam Rubber Tyred Gantry Crane: This double-girder structure has a load-bearing capacity of 5 to 50 tons and features two parallel box girders, providing greater structural strength and rigidity. For precast beams of equal length or asymmetrical loads, where optimal load distribution is required, users can choose to install a single hoist trolley above the main girder or install one independent electric hoist at each of the four corners to achieve synchronized multi-point lifting.

المزايا

This electric hoist rubber tyred gantry crane is characterized by high mobility, high efficiency, and strong adaptability to various site conditions. Compared to rail-mounted gantry cranes, it does not require the installation of fixed tracks and can be moved freely on rubber tires, making it suitable for different work areas and temporary stockpile sites. Their key features include:

Specifications vary by girder configuration, with capacity ranging from 1 to 50 tons and span from 6 to 35 meters.

Parts and Components

This electric hoist rubber tyred gantry crane consists primarily of a main girder, rubber-tired gantry legs, an electric hoist, a travel mechanism, an electrical control system, and safety devices. The various subsystems work together to perform lifting operations.

• العارضة الرئيسية: The main girder forms the load-bearing structure. This component ensures sufficient resistance to bending and torsion under rated loads.
• Gantry Legs: The gantry legs support the main girder using an A-frame or rigid leg structure.
• رافعة كهربائية: The electric hoist is a lifting mechanism installed above or below the main girder. Optional configurations include CD/MD-type wire rope hoists, European-standard wire rope hoists, or, for double-girder models, hoist trolleys and four hoists operating in synchronized mode.
• آلية السفر: This component consists of drive wheels, a motor, and a gear reducer and is primarily responsible for propelling the crane across the ground. The system employs variable-frequency drive technology to effectively suppress load sway during material handling.
• نظام التحكم الكهربائي: The electrical control system uses a control cabinet to manage hoisting, travel, and safety interlock functions via a pendant controller or wireless remote control.
• أجهزة السلامة: Safety devices include overload limiters, hoisting limit switches, anti-collision buffers, and emergency stop controls.

الأسئلة الشائعة

What does an RTG Crane with an electric hoist do?

Users employ this equipment to lift and transport heavy loads between precast concrete plants, steel structure manufacturing workshops, and storage yards. Unlike bridge cranes, it does not require the installation of fixed tracks and offers a high degree of mobility and flexibility.

How does this crane differ from a container RTG crane?

Unlike container RTG cranes, which are specifically designed for handling containers, this equipment is intended for general industrial lifting applications. It features a lighter-duty cycle and a smaller footprint, and offers lifting configurations suited for precast concrete, steel, and manufacturing environments.

Can the hoist configuration be customized on a double girder crane?

Yes, double girder models accept either a single hoist trolley or four independent electric hoists positioned at the corners, allowing synchronized multi-point lifting for long or asymmetric loads such as precast beams.

Is a rail foundation required for installation?

No, because the crane travels on rubber tyres rather than fixed rails, installation generally needs only a level, load-bearing surface, which reduces civil engineering costs and the time needed before operation begins.
