Installing a bridge crane can be difficult if your building lacks overhead space or has several overhead barriers or difficulties needs be solved.  However, there are cost-effective alternatives for applications requiring overhead material handling hoist and crane in a building with restricted headroom.

Under-running bridge cranes are appropriate for applications requiring overhead hoist and crane in a plant with limited production space or low headroom. Under slung bridge cranes are supposed to be versatile and functional. While top-running cranes are built to lift heavy loads, under-running cranes are built with an ergonomic design that provides versatility and usability. Because under-running bridge cranes travel beneath the runway, you can increase the distance between the ground and the hook.

Under-running cranes use end trucks that move on the crane runway's bottom flange and can be suspended directly from the overhead building structure without the use of interfering support columns. A long under-running system may readily function using many runways—even in very large bays—than a top-running system. This reduces the depth of the bridge girder while also reducing the weight of the operational equipment, resulting in lower equipment costs and lighter design requirements for the building or support structure.

If your application requires the use of an overhead bridge crane system but you're concerned about insufficient headroom, too much weight on your support structure, or maximizing lift distance, an under-running, enclosed track workstation bridge crane may be the ideal option. Let's take a look at some of the benefits of a high-performance workstation bridge crane, as well as some potential drawbacks—depending on your application.

Underslung bridge crane of 5 tons for concrete batching plant in Canada

With the development of fundamental constructionin recent years, the usage of concrete batching plants has grown in popularity. One of Langley City's concrete batching factories is looking for a more effective material handling crane solution for their production lines. Every day, the company produces thousands of cubic meters of concrete to suit the region's demand for construction projects.

To ensure the efficiency of concrete production and improve productivity, they ordered a 5 ton underhslung bridge crane with a European electric hoist.

Overview of 5 ton underslung bridge cranes

• Date: February 25, 2023.
• Applications: 5 Ton Underslung Bridge Crane Used for Concrete Batching Plant.
• Project Service:From crane design, manufacture, and installation of a 5 ton bridge crane with European style. The overhead crane was widely used for a concrete batching plant, to transport and raise concrete blocks and other goods, etc.
• Production time: The project will be completed within three months.
• Project location: Langley City, Canada.

The 5 ton European style single girder underslung bridge crane is an important part of the plant's production line. It's used to hoist and transport raw material like cement, sand, and aggregate to the mixing area, where they're mixed together to make concrete. The single girder underhung crane is also used to move finished concrete to storage locations for further processing.

The single girder 5 ton under running bridge crane is suitable for handling heavy loads during the concrete batching process. With its high load capacity and precision control, the overhead crane can rapidly and efficiently lift and transport enormous amounts of concrete, saving time and labor expenses.

Main Features of European style underslung bridge cranes

• The suspension single girder bridge crane has a compact structure and low headroom, which saves space and lowers the building's height. It can also function in tight spaces and corners, and it has a versatile configuration.
• An underhung bridge crane is light and quiet, reducing the load on the building structure and improving the working environment. It also moves smoothly and precisely, ensuring the safety and effectiveness of material handling.
• The NR-type European style electric wire rope hoist features a modular design and a wide range of capabilities, ranging from 1 to 32 tons, that may be adjusted based on the customer's needs and application. It also has a long service life and a minimal cost of maintenance.
• The FEM style electric wire rope hoist features a high lifting speed and variable speed control, which increases the underslung bridge crane's productivity and energy savings. It also consists a reliable braking mechanism and an overload protection device to assure the operator's and the load's safety.
• Because of the vast scale and complex layout of the concrete batching plant, a flexible and efficient material handling system is required. An underslung bridge crane with an European style hoist with a long span and a large coverage area can meet this demand. It can also be combined with other pieces of machinery such as conveyor belts, hoppers, and silos.

Benefits of undeslung bridge crane

• Save Space: Save space and lower the plant's footprint. A underhslung bridge crane with a FEMstyle electric hoist can be put on a single or double girder crane to span a big area while taking up little ground space. This can open up additional room in the plant for other equipment and activities.
• Increase efficiency: It can improve the batching process's efficiency and accuracy. A underhslung bridge crane with a FEM style electric hoist may carry concrete materials from one area to another rapidly and precisely, such as from the mixer to the storage silo or from the silo to the truck. This can save waiting time and material waste while also improving the quality and consistency of the concrete.
• Improve worker safety and comfort: It can improve worker safety and comfort. A European standard underhslung bridge crane can be operated remotely or automatically, reducing physical work and human error in large load lifting and transportation. Accidents and injuries caused by falling objects or collisions can also be avoided.
• Environmentally friendly: Furthermore, a underhslung bridge crane with FEM electric hoist can reduce noise and dust pollution in the factory, resulting in a more comfortable working environment.
