An overhead crane, also known as a bridge crane, is a large machine used for lifting and moving heavy objects in large warehouses or factories. The crane's lifting mechanism is suspended from beams that run parallel to the bridge crane's main body. An ABUS overhead bridge crane is a type of overhead crane made by the ABUS company.
ABUS overhead bridge cranes are used for the horizontal transportation of heavy goods. The bridging of the crane system, which comprises a bridge beam that runs on two parallel gantry rails, is supported by end carriages on both sides. The crane can be run manually or automatically on the ground or from a cabin or console. Power is supplied via a festoon system or continuous bus bar.
The two main types of ABUS overhead bridge cranes are the single-girder and the double-girder design:
Single-girder ABUS overhead bridge cranes
Typically, their girder is an I-beam, and they can be mounted on an elevated runway beam or brackets connected to a building column. A runway beam is a horizontal beam from which a crane, hoist, or other piece of equipment may operate to lift, lower or move materials or personnel. These cranes are better suited for lighter objects that weigh up to 5 tons and for smaller areas with limited space. A top-running crane runs on an elevated beam or rails. By contrast, an under-bracket crane runs below an I-beam to lift items. In practice, this means the end carriages ride on top of the runway beams, giving the crane a greater hook height so it can lift taller objects.
Double-girder ABUS overhead bridge cranes
The main difference between a double-girder overhead crane and a single-girder crane is the two girders supporting the hoist. This bridge crane type is usually more difficult to install, requiring a lot of room to set up. However, it can support a lot of weight and lift heavier items with a higher payload capacity. A double-girder overhead crane can lift heavier objects, typically in the range of tens of tons to hundreds of tons. Their hoist is placed between the main girders, offering the crane greater hook height and lifting capacity. Like the single-girder overhead cranes, a double-girder crane can also be a top-running or a flat-bottom running one. A top-running double-girder crane runs on top of the rails like its single-girder counterpart. In contrast, a double-girder flat-bottom crane runs on parallel rails with a runway beam.
Load Capacity:
Overhead bridge cranes can carry different weight loads. Smaller cranes may carry a few tons, while bigger industrial ones can carry dozens to hundreds of tons.
Span Length:
This is the distance between the two outer ends of the bridge. It determines how wide an area the crane can cover. Span lengths usually range from 10 feet to over 100 feet, depending on the crane size.
Lifting Height:
This refers to the maximum height the crane can lift objects. It is measured from the crane's rail/track to the highest point of the hook/lifting device. Lifting heights vary, but some cranes can reach up to 50 feet or more.
Control System:
The way an overhead crane is controlled. Common control systems include pendant controls, radio remote controls, and joystick controls.
Power Source:
How the crane gets its power. Overhead cranes can be powered by electricity, batteries, or diesel engines, depending on the model and application.
Material of construction
The structure is typically made from heavy-duty steel or aluminum to ensure it can securely support the weights and functions of lifting operations over prolonged periods.
Regular Inspections:
Scheduling routine inspections by trained technicians is a good way to maintain overhead cranes. The inspectors will examine major components like the bridge, rails, hoist, and electrical parts to ensure everything works well.
Lubrication:
Overhead cranes contain many moving parts. Lubricating them is important to prevent wear and tear. Regularly apply grease or oil to the crane wheels, hoist chains, trolley bearings, and other parts that need it.
Maintenance of Hoist:
Since an overhead crane’s hoist is responsible for lifting and lowering items, it is crucial to take good care of it. Remember to inspect the hoist brakes, direction of rotation, limit switches, and audio-visual alerts. Ensure they are all working right and do repairs if necessary.
Rail Cleaning:
The overhead crane runs on rails fixed in place, so it's necessary to keep the rails clean. Remove any dust, grease, or debris that builds up on the rail surface. This helps the crane wheels move smoothly and keeps operations safe.
Logistics Industry
In the logistics sector, an overhead bridge crane can be used for item sorting and repositioning.
Aerospace and Automotive Industries
Due to the demanding nature of their operations, the automotive and aerospace industries require highly accurate and dependable lifting solutions. The bridge crane's ability to lift heavy objects also makes it suitable for use in the aerospace industry. Such objects include aircraft body parts, titanium frames, and other high-value parts.
Workshops and manufacturing plants
An overhead bridge crane is perfect for workshops and factory floors where heavy items need regular lifting, repositioning, or assembly. Overhead cranes eliminate the need for manual lifting. They make assembly lines more seamless, efficient, and safe.
Construction
An overhead crane is widely used in the construction industry. It facilitates the efficient lifting of building components such as beams, heavy steel plates, and trusses. It is the go-to lifting machine for constructing large commercial facilities and industrial-scale housing projects.
Dock and Marine Operations
Overhead cranes are widely used for lifting and repositioning cargo containers and other bulky items at marine terminals and ports.
Wind Energy
Overhead cranes are a common sight in wind energy farms. They help to lift the turbine's nacelle and generator. Additionally, bridge cranes aid in mounting large solar panels on rooftops in urban setups.
Choosing an appropriate bridge crane is important for the safety and productivity of a business. The following factors can be taken into consideration when selecting an ABUS overhead bridge crane.
Understand the needs of the business:
Identify the intended purpose of the crane, such as whether it is used for loading and unloading materials at a dock or moving heavy equipment in a workshop. Consider the weight and size of the items to be lifted, the crane's operational environment, and frequency of use. The floor or hook-hoot height is the distance between the floor and the height from which the crane will be used to lift objects. The available space is the physical dimensions of the area where the crane will be used, including width, length, and height.
Determine the appropriate type of bridge crane:
ABUS overhead cranes are suitable for heavy-duty applications where high lifting capacities and large spans are required. Consider using an ABUS lightweight overhead crane if the lifting task involves frequent handling of lighter items or the crane needs to be maneuvered in a limited space.
Consider the control system:
An overhead crane can be controlled by a cable, remote control, or radio. Choose a crane with a control system that is user-friendly and can be used in the operational environment.
Assess the safety features:
Look at the crane's built-in safety features, such as overload protection and emergency stop buttons, to ensure a safe lifting operation.
Think about future needs:
Consider the possibility of expansion or changes in the operational environment to meet the future needs of the business by selecting a crane that has the capacity to meet those requirements.
Q: What is an Abus overhead crane used for?
A: It is a type of machine that is used to help lift heavy things. It is good at moving items that weigh a lot in a place like a factory.
Q: What are the Benefits of an Abus Cranes?
A: An Abus crane allows users to move big and heavy things easily from one point to another in the air without help from other people. It makes moving big stuff simple and saves time. An Abus overhead crane and moving big things horizontal and better than a regular crane. It is better because it does not need floor space to move. Using an Abus crane can help make space on the ground.
Q: What is the difference between Abus and overhead crane?
A: An overhead crane is a general term for a crane that is fixed above the floor level to assist with the horizontal movement of items. The Abus is a product model name.
