A bridge and gantry crane functions as an overhead crane. Bridge and gantry crane operation moves cumbersome things from one place to another in a safe and precise way. These cranes operate in manufacturing, shipping, and warehouses.
Enhancing Material Handling with a Bridge and Gantry Crane
Gantry crane, overhead bridge, and gantry crane appear synonymous because they describe a crane that straddles its load. Gantry and bridge cranes are overhead cranes that differ in structure and versatility.
A gantry crane moves on rails using wheels and is supported on its frame. They can be moved to different indoor and outdoor locations and are easy to assemble. However, they are less robust for heavy lifting than bridge cranes.
The bridge crane remains fixed into the roof or walls of a building as a permanent installation. It is mounted on girders that support the structure of the building. The rafters are runways along which the crane moves. It has a hoist and trolley that run alongside the bridge.
An efficient bridge and gantry crane remains key in boosting productivity in industries and large-scale storage and transportation businesses. The crane performs heavy-duty operations in shipping, relocation, and staging.
The benefits of this crane include:
- Significant reduction of workplace accidents due to the elimination of human input in lifting materials
- They improve workflow and boost productivity
- They are eco-friendly
- Lower operational costs
- Reduced material and production damage
With proper maintenance, they can last over 40 years, sometimes outliving the company or the structures that used or housed them.
They are installed as overhead equipment inside buildings or hoisting loads of a specified capacity. At locations where a bridge and gantry crane operates, there are computerised or manual controls to match the correct type and size of load to the crane’s capacity.
Some functions of a bridge and gantry as an overhead crane include:
- Delivering raw material into a machine during manufacturing processes
- Moving heavy materials to different locations or positions
- Shifting containers at a railyard or shipyard
- Loading or unloading trucks
- Moving parts at assembly lines in industries
The cranes must be appropriately sized and installed to perform their operations without harming the operators and loads they handle. Such risks arise from broken or malfunctioned components due to poor maintenance. Another risk is overloading the crane and using inexperienced or untrained operators.
Training in Bridge and Gantry Crane Operation
Worksite managers should ensure all workers have adequate training, relevant certification, and information to operate overhead cranes. Crane operators require a High-Risk Work (HRW) Licence as part of qualification to work as a crane operator.
They must also have a Certificate 111 in Crane operations showing they have received instruction from a Registered Training Organisation. These are mandatory and nationally recognised qualifications. The TLILIC0023 is a licence that allows those who attain it to operate slewing mobile cranes of up to 60 tonnes.
There is funding for the training for those eligible for the support. The training blends theoretical and practical learning, usually done at a crane operating site. The training usually takes about a week to complete, and the types of licences issued depend on the type of crane and its capacity. The approved training institutions have an RTO number. A crane operator’s HRW licence requires renewing every five years at a fee.
Conclusion
Businesses and industries that require hoisting and moving extremely heavy loads find it prudent to invest in an overhead crane. They should ensure the cranes undergo periodic evaluation and maintenance. Then, they can expect safe and efficient operations and increased productivity.
