Overview of double girder eot crane

What is a double girder eot crane?With double girder crane design, the overhead travelling cranes adopts two girder beams to make up the crane travelling bridge which are supported by an end truck / end carriages on each side. Frequently, the double girder overhead crane are designed in top running crane configuration in which the hoist trolley or open winch trolley run on a rail or track installed on top of the bridge girders. With a double girder design, overhead cranes help to gain the depth of the cross girder if the hoist is placed between or on top of the cross girders.

Double girder overhead travelling cranes are widely recommended for heavy-duty material handling with heavier lifting capacities and longer spans. Because of this, the crane parts and components of the double girder crane system, including the hoist trolley and open winch trolley, are more complex in design which makes double girder overhead travelling cranes more expensive than a single girder overhead crane.

With double girder design, the overhead bridge cranes can be added with specialized features like crane walkways and maintenance platforms,etc. Due to more materials are adopted for double bridge beams and runway system, the installation of double girder overhead travelling cranes have to take the supporting structure of the building into consideration and if necessary extra tie-backs or supporting columns can be added. Double girder overhead travelling cranes with process crane configurations and specifications will be the best fit material handling solutions for your particular applications.

General parameters & specifications of double girder overhead crane

Double girder bridge cranes are designed for heavy material handling with capacity of more than 20 tons, thus, a double girder overhead bridge cranes also can be referred as a heavy duty overhead crane. With various below the hook devices, the double girder eot cranes are widely used in various industrial applications. Among them, the hook double girder overhead travelling crane is one of the mostly used heavy material handling crane equipment with the lifting capacity from 5 ton to 550 ton, working class up from A4 to A7.

• Crane type: Double girder overhead travelling crane with top running crane designs
• Lifting capacity of double girder overhead crane: 5 ton, 10 ton, 20 ton, 30 ton, 40 ton, 50 ton, up to 100 ton
• Span of double girder overhead crane: 7.5m~35.5m
• Working class of double girder overhead crane: A5,A6

double girder overhead travelling cranes can offer low headroom configurations designed with European standards of FEM, DIN and ISO, for heavy loads handling with features of lower deadweight, larger hook height and longer crane span, which are particularly good solutions for general manufacturing, workshops, warehouse and assembly lines,etc. Process double girder overhead travelling cranes are available. Please contact us to get free consultation, double girder eot crane drawing, and overhead crane brochures, etc.

Top running crane vs. Under hung cranes

Double girder overhead travelling cranes can be designed either in top running crane or under running crane configurations. A top running double girder bridge crane will provide the most overhead room, as well as the greatest hook height. An under running double girder overhead travelling cranes are mounted on a runway structure that has been integrated into the ceiling structure of the building which are an effective solutions for low headroom or tight headroom clearance applications.

Top running double girder overhead travelling crane

Under running double girder overhead travelling crane

Usually, the double girder underhung bridge cranes are difficult and expensive. For various conditions, the double girder overhead travelling cranes usually are adopted the top running crane designs.

Hoist trolley crane & Open winch cranes

Double girder overhead travelling cranes are the first choice for heavy duty material handling in workshops which needs a very large range of crane spans, hook height and travelling speed range. Generally, the double girder eot cranes are available with multiple hoisting systems including Hoist trolley system & Open winch trolley system, depending on the wight of lifting loads and lifting requirements.

Double girder hoist trolley

Crane hoist trolleys are designed for double girder crane and are widely used for heavy duty lifting operations with higher safety and stability. The hoist trolley are runs on along the top of edge of two girders and the wire rope with hook will descend between the two girders to handle the load, which enables the maximum possible height of lift under the beam girder, however, on the hand more roof space will be required above the crane beams or girder, due to it sits on the top of crane beam girders.

Chinese style hoist trolley-The Chinese style hoist trolley adopts the CD/MD wire rope electric hoist trolley or electric chain hoist with frame as the lifting mechanism and lifting capacity is from 5 ton 32 ton, and the double girder electric hoist overhead travelling crane is much stronger, safer in use compared with that of single girder overhead electric crane. Notice: The Chinese style hoist trolley also can meet the European crane standards and operation requirements. Contact us to learn more.

European style hoist trolley-European standard FEM/ DIN standard low profile hoist trolley with lifting capacity are up to 80 ton. The European low profile hoists trolleys are used on double girder cranes configurations, such as, types of overhead crane & A frame gantry cranes, etc. With low profile hoist designs & double girder designs, the hoist hook can be placed on and between the two main beams which offers a larger lifting height comparing with the double girder cranes with Chinese traditional designs. With compact structure and low profile design, the European FEM / DIN standard crane hoists can be used in workshops with limited space with reliable and stable performance,which offer you a chance to save investment on workshop construction initially.

Double girder open winch

Build up open winch and electric winch trolleys are adopted on double girder cranes as the lifting system for handling heavy loads with capacity from 5 ton 500 ton. According to different design style and features, the overhead open winch crane can be grouped in the following types:

Open winch with Chinese traditional design-These types of open winch and electric crane winch trolley are frequently adopted on the Chinese traditional heavy duty double girder cranes with capacity from 5 ton to 500 ton,with the features of safe, flexible, powerful, reliable & stable.

European open winch crane design - European crane winch is a process crane components for heavy duty double girder overhead travelling cranes and overhead gantry cranes. The European winch trolleys are tailored to meet the specific requirements of your application and process cranes. The process winch trolleys are vary versatile and applicable to a variety of industrial applications.

General configuration of double girder eot cranes

• Box section double beam girders, low deadweight, reducing investment.
• Crane girders can be processed to fit the requirements of building structure and application conditions.
• Best utilization of the available height and space due to compact hoisting trolley design with minimum approach dimensions and large hook path.
• End carriages, welded box-shape structure with torsionally rigid,
• Modular design of end trucks and crane wheel sets. Adjustable wheel group can effectively prevent the gnawing of rails.
