What is portable overhead crane?

Mobile crane is widely used in warehouse for transporting the material that is heavy for labor and not convenient for big size travelling crane. It adapts to manufacture of molds, automobile factories, mines, construction sites. Compared with normal lifting crane, portable crane is smaller and easier to operate. It can be matched with manual hoist, chain hoist, and electric hoist to use together.

Four basic configurations

This section specifies the kind of equipment you require. Overhead cranes come in four basic configurations;
Top Running (T/R) – The crane bridge travels on top of rails mounted on a runway beam supported by either the building columns or columns specifically engineered for the crane.

Under Running (U/R) – The crane bridge travels on the bottom flange of the runway beam which is usually supported by the roof structure.

Single Girder (S/G) – The crane consists of two end trucks, a single bridge girder and the trolley hoist unit. The trolley runs on the bottom flange of the bridge girder.

Double Girder (D/G) – The crane consists of two end trucks, two bridge girders and the trolley hoist unit. The trolley runs on rails on top of the bridge girders.

Contact Us

A variation on these types of overhead crane are Gantry Cranes. These cranes are essentially the same as the regular overhead cranes, however, the bridge girder(s) are connected to “legs” on either side of the span. These “legs” eliminate the supporting runway and column system and connect to end trucks which run on a rail either embedded in, or laid on top of, the floor.

For some applications, only a Trolley Hoist is required. For instance, in the case of a monorail system a Trolley Hoist unit similar to the one used on single girder cranes is mounted on a beam which might be used to service an assembly line within the client’s facility. Other clients may have an existing single or double girder crane bridge and may just want to replace the hoisting unit. In most of these situations, capacity permitting, we can provide either a Wire Rope or Chain Hoist.

A large construction project will always involve the use of cranes that are able to move incredible amounts of weight, typically associated with generators, steel girders, and other components of the construction project. These can have extremely long booms allowing them to lift and position everything into place, often seen in large cities where skyscrapers are being put up. There are different types of cranes that are used and some of them are actually very lightweight and flexible, including portable overhead cranes. The following information can be used to show you how they work, and also where you can purchase them for discount prices.

Portable overhead cranes details

These are extremely small cranes, ones that can be made of steel or aluminum, capable of lifting several thousand pounds. Sometimes they are referred to as a gantry crane, having to separate sides, and a beam across the top with a hook in the middle. You will often see these in a garage where they are taking out motors that can be extremely heavy. They are designed to be extremely tough, though lightweight in construction, and can be broken down and transferred to any location. They are often used in place of forklifts, measuring no more than eight feet in width, allowing you to get into very tight or narrow spaces. It is also tall enough to walk under so you are not bumping your head, providing you with a lot of versatility for any job that you have in mind.

Components of single girder light duty overhead crane

These cranes are equipped with electric hoist and widely used in workshop, warehouse, and material stores and so on. Our factory is specialized in manufactory crane of this series.

Crane girder:

The crane girder is of welded girder construction. This result in lower dead weight with a high degree of vertical and horizontal rigidity and small wheel loads being transmitted to the crane runway!

Wire rope electric hoist is assembled by several parts: Hoisting Gear Box, Hoisting Motor with brake, Rope Drum, Electric Control Panel and Traveling Trolley. All these units are separately accessible and promptly disassembled cost and stopped.

Motor: Hoist Motor is a taper type rotor motor with braking, it is made by Nanjing special motor factory, it is of the best quality motors, it has bigger torque, so it can be adapted to moving frequently, the Maximum torque is 2.4-3 times than the rated torque.

Gear box: Hoist Gear Box has specially treated gears for high wear resistance. Each Geared Shaft assembly is supported on ball or roller bearings, to ensure smooth, low-friction operation.

Wire rope: Hoisting ropes comply with the exporting standards. The leading rope taken by the Drum does not slip sideways when slack. The factor of safety, on the nominal breaking strength of the rope is six.

Rope drum: Grooved hoist Drum, seamless pipe of adequate length to be wounded in one layer and to provide proper support for the rope to minimize abrasive wear is provided. Drum Shaft resolves on Ball Bearings for ensuring smooth running.

Control method: Pendent line with press button or remote control or both

Safety feature:

Weight overload protection device,
Top quality long time bearing polyurethane materials buffer,
Crane traveling limit switch,
Voltage lower protection function,
Emergency stop system,
Current overload protection system,

Design and construction rules:
All the standards which is required for the crane is the Chinese standard

High efficiency of portable overhead crane

Portable overhead cranes offer a convenient alternative to traditional overhead cranes. These lifting cranes, which are supported by two legs rather than being mounted directly to the building, can be moved anywhere that you need to use them. This makes them far more versatile than standard overhead cranes and also provides a great deal of convenience since they can be moved wherever they are required.

Imagine, if you will, that you have an extremely heavy object that you need to load onto a truck. There are quite a few different approaches that you could take to get the job done. First, you could have your workers try to manually lift the item onto the truck. Unfortunately, this would put a great deal of strain on their bodies. In some cases, they could even wind up getting injured if they tried to lift more weight than they could comfortably handle.

A far better option would be to use a portable overhead crane. Using one of these cranes is extremely easy. All you have to do is bring it to the area where the heavy lifting is going to be done. Next, a worker simply attaches the hoist to the item that needs to be lifted.

Depending on the type of crane that you purchase, the load is lifted off the ground either electronically or manually. With an electronic crane, the power of electricity is used to raise the load up into the air and to move it to its final destination. This is the easiest option since it requires little to no manual labor. However, these machines are quite a bit more expensive than manual machines which may not make them practical for all businesses.

Fortunately, even manual cranes make the process of lifting heavy items easy. Because the hoist does most of the work, any worker who is operating the crane has to exert very little effort. This is far easier than trying to lift something heavy without the assistance of the crane. Additionally, using one of these cranes, a single person can lift a heavy load on their own rather than requiring multiple people to help with the lifting process. This can allow you to get the work done using fewer workers. Because you have to pay fewer people, this can significantly cut your costs.

When you consider how convenient a portable overhead crane is to use, it is easy to see why they are such a smart investment. They can help your workers increase their productivity without adding any more physical strain to their workday. In fact, in many cases, these cranes can help reduce strain, making the workday easier for your employees. As an added bonus, they can also help reduce the likelihood of long-term injuries resulting from repetitive strain. This can ensure that your workforce stays healthy and strong for many years to come.

If you have any type of heavy lifting to do at your place of business, a portable overhead crane can be a convenient way to get it done.
