Crane Kits refer to overhead crane kits or overhead bridge crane kits for small capacity top-riding and underhung cranes with electric hoists and bridge controls (electrical panels), end trucks. They are the lifting equipment which are used to carry out loads lifting. With the help of end trucks, the main girder of crane kits runs along the track longitudinally, which can make full use of the space under the bridge to transport the loads, totally free from the obstruction of ground equipment.

            Crane Kits for small capacity top-riding and underhung cranes with electric hoists and bridge controls (electrical panels), end trucks. They are the lifting equipment which are used to carry out loads lifting. With the help of end trucks, the main girder of crane kits runs along the track longitudinally, which can make full use of the space under the bridge to transport the loads, totally free from the obstruction of ground equipment. Crane kits are the important tool to realize mechanization and automation in modern industrial production and lifting transportation.

           Just simply combine components hoist, end trucks and controls as a kit, it is not traditional complete crane systems. Actually, a full  and complete “crane kit set” for local bridge crane building will included all components needed less the girder. The complete components of crane kits include the main girder, two end trucks, one electric wire rope hoist with motorized trolley, one electric festoon system, one cable with quick-connect plug, one pendant controller, and one control panel with variable frequency drives. What’s more, we will provide the maintenance and parts manual to fully meet customers’ requirements.

           The average crane kits building time will roughly take  twenty (21) hours to build from start to finish. A supplied kit with tailored component packages for efficient single or double-girder and suspension crane solutions that save you time when building. Crane sets must be based on standardized components for simple and user-friendly assembly and contain plug-&-play principle eliminating wiring.

           The wire rope hoist of crane kits is exceptionally reliable. The large drum diameter provides hoist the best wheel loads and lowest headrooms in industry. Besides, it also gives exceptional heights of lift and hook approaches. The hoist motor, hoist gear box and hoist brake which are equipped with crane kits, all have a high quality and well performance. In the festoon systems, we use plug connections on cables which makes the installation, repair and replacement become more quick and easy. It extremely saves the cost of an electrician and expensive down time. Furthermore, independent C-track for pendant station provides operator a safe distance from load.

           In our crane kits, we offer pendant control to our customer. All crane motions will be controlled from convenient plug-in push button station which includes the emergency stop button. The structure is made of rectangular steel tube or steel plate. Besides, the steel’s material is national standard Q235B  or Q345B, which can provides more security to the load works and prolongs our  products service life. The end trucks offer great stability thanks to their torsionally rigid, enclosed box-section profile with a reinforced connection  plate and welded diaphragm plate. Maintenance-free drives with anti-friction bearings lubricated for life and travel wheels made of spheroidal cast iron provide for favourable travel characteristics.

           Different types of main girder are included in  our crane kits, like single girder and double girder. In order to meet the  different needs of different main girders, we supply matching components to our customers.

           They are widely used to assemble, repair, load and  unload, transport, check at workshop, construction, factory, indoor-outdoor  warehouse, metallurgy and so on. Besides, they are used in industrial and mining enterprises, iron and steel chemical industry, railway transportation, port terminals and logistics turnover, auto-mobile industry, ship building industry, electronic assembly industry, food production and mechanical production industry etc. What’s more, it is prohibited to use our crane kits in the corrosive, combustible or explosive environment.

           They are also called Bridge crane kits, Single girder overhead crane kits, Double girder overhead crane kits.

1.The reasons to order an Lightweight Overhead Crane Kit
           It can seem like a daunting task when you are ready to  purchase an overhead crane for your business. You must to do many steps to buy a crane, like check out all of the different crane companies, get quotes, schedule an install, and worry about  paying for installation. Therefore, some businesses don’t want to use overhead cranes, because they think that they can’t afford the time or the money which  it will take to set one up. But these business owners don’t know that there is an more simple way to do all of this: with an lightweight overhead bridge crane kit. Here are 5 well reasons about why business owner should purchase an overhead crane kit:

  • Customisation: If you don’t want to get message from someone about what they have in stock or purchase one out of catalogue, it is suitable for you to buy the overhead bridge crane kits which is designed specially for your business. Besides, the well-performance overhead bridge crane kits can be installed under the help of professional crane service person to meet any business requirements, large or small.   

  • Installation Costs: It is very simple to install and plug in the overhead cranes kits when they are used. Therefore, it is unnecessary to hire an electrician or experienced worker to operate it. What’s more, it also can save the installation costs for business owners, which can add up to thousands of pounds with larger cranes.

  • Faster Delivery Times: According their needs, it is convenience for business owners to choose their own shipping times and the most cost-effective shipping options. Compared with those cranes which have to be scheduled through a crane company, there is also a quicker delivery time for the overhead crane kits.

  • Respected Names in Overhead Cranes: Overhead crane kits adopt well-respected name materials as their components. Business owners can have a confidence that they are getting the highest quality materials in their crane kits by choosing from known name parts.

  • Installation When Desired: Instead of crane company arrange the assemble time, business owners are free to choose what’s the right  time to install their overhead bridge crane kits, even in the midnight.
