7.5 Ton Grab Bucket Overhead Crane Kit for Garbage Handling Indonesia
Short Video Description
This video shows a 7.5 ton grab bucket overhead crane kit supplied for garbage handling in Indonesia. The project includes 3 sets of grab overhead cranes for lifting, transferring and feeding waste in a garbage handling facility.
The 7.5 ton grab bucket crane is designed for repetitive bulk waste handling. The crane uses an overhead bridge structure, electric grab bucket and lifting mechanism to pick up garbage from the waste storage pit and discharge it into the required hopper, feeding system or processing equipment.
For waste handling applications, the crane and grab bucket are selected according to garbage density, grab volume, lifting capacity, lifting height, crane span, working cycle and required throughput. The actual load can vary significantly depending on the type and moisture content of the waste.
Yuantai engineers can supply the complete overhead crane kit, grab bucket, hoisting system, travelling mechanism, electrical control system and commissioning service according to the customer's waste handling plant layout.

How Does a 7.5 Ton Grab Overhead Crane Handle Garbage?
A grab bucket overhead crane for garbage handling uses a motorized grab to pick up waste from a storage pit or unloading area. The loaded grab is then lifted and moved by the crane to the required hopper, waste feeder, furnace or processing line.
After reaching the discharge position, the grab opens and releases the garbage. The empty grab then returns to the waste pit for the next handling cycle.
This repetitive lifting process makes the 7.5 ton grab crane suitable for waste transfer stations, municipal solid waste facilities, refuse handling plants and waste-to-energy applications.
7.5 Ton Grab Crane for Waste-to-Energy and Garbage Handling
A garbage handling overhead crane is commonly used above waste storage pits where large quantities of refuse must be moved continuously. The grab bucket allows the crane to handle loose and irregular waste without slings or pallets.
- Municipal solid waste handling
- Waste transfer stations
- Waste-to-energy plants
- Garbage storage pits
- Waste bunker feeding
- Refuse loading and unloading
- Waste sorting and processing facilities
- Industrial waste handling
Why Use a Grab Bucket Overhead Crane for Garbage Handling?
A grab bucket overhead crane is well suited to garbage handling because the grab can directly collect loose waste from a storage pit and discharge it at the required location.
The overhead crane arrangement also keeps the lifting equipment above the waste pit, allowing the crane to cover a large working area while supporting repetitive waste transfer and feeding operations.
For a high-throughput facility, the crane can be designed for frequent grab cycles and coordinated with the waste feeding process.
3 Sets of 7.5 Ton Grab Cranes for Indonesia Project
This project involves 3 sets of 7.5 ton grab bucket overhead cranes for garbage handling in Indonesia. Supplying multiple cranes requires consistent equipment configuration, electrical coordination and commissioning procedures across the complete project.
Yuantai can coordinate the crane structure, grab bucket, hoisting mechanism, travelling system, electrical control and commissioning for multiple crane sets according to the plant layout and operating sequence.
Grab Overhead Crane Installation and Commissioning
For a garbage handling crane project, installation and commissioning are important parts of the complete supply scope. The crane must be checked after installation before entering regular waste handling operation.
- Mechanical installation inspection
- Crane bridge and end carriage inspection
- Grab bucket assembly inspection
- Electrical connection and control inspection
- Hoisting and travelling direction checks
- Limit switch and emergency stop testing
- Load testing and functional testing
- Grab opening and closing tests
- Operator control and commissioning
- Final operating inspection
How Yuantai Designs a 7.5 Ton Garbage Handling Crane
Yuantai engineers design the grab bucket overhead crane around the actual waste handling process and plant layout.
- Confirm waste type and density
- Determine maximum grab load
- Select suitable grab bucket volume
- Confirm 7.5 ton crane capacity
- Determine crane span and lifting height
- Check waste pit dimensions
- Confirm hopper or feeding positions
- Select suitable duty class
- Check crane wheel loads and runway structure
- Configure cabin, radio remote or PLC control
- Plan installation and commissioning requirements
This engineering approach helps match the 7.5 ton grab crane with the required waste handling capacity, working cycle and facility layout.
FAQ: 7.5 Ton Grab Bucket Overhead Crane for Garbage Handling
Common questions about grab overhead cranes, garbage handling cranes, waste pit cranes, crane kits and commissioning for waste handling plants.
1. What is a 7.5 ton grab bucket overhead crane?
A 7.5 ton grab bucket overhead crane is an overhead bridge crane equipped with a grab bucket for lifting and transferring loose garbage and other bulk waste materials.
It is commonly used in waste handling plants, garbage storage pits, transfer stations and waste-to-energy facilities.
2. Can a 7.5 ton grab crane handle municipal solid waste?
Yes. A grab overhead crane can handle loose municipal solid waste, provided the grab bucket, crane capacity and duty class are selected according to the actual waste characteristics.
Waste density and moisture content should be considered when determining the maximum lifted load.
3. Why is a grab bucket used for garbage handling?
A grab bucket can directly collect loose waste from a storage pit without using slings, pallets or manual loading equipment.
The grab can then discharge the waste into a hopper, feeder, furnace or other processing system.
4. What information is needed for a 7.5 ton garbage crane quotation?
Provide the waste type, approximate density, required grab volume, crane capacity, span, lifting height, waste pit dimensions, working frequency and discharge position.
A plant layout showing the waste pit, hopper and feeding equipment helps Yuantai engineers determine the required crane working envelope.
5. What duty class is suitable for a garbage handling overhead crane?
The duty class depends on the number of grab cycles, operating hours, lifting frequency and required service life.
Yuantai engineers select the appropriate ISO/FEM duty classification according to the actual waste handling schedule rather than applying the same class to every project.
6. Can the 3 sets of grab cranes be supplied and commissioned together?
Yes. Multiple 7.5 ton grab overhead cranes can be engineered and supplied as a coordinated project, including crane equipment, grab buckets, electrical systems and commissioning support.
For a three-crane project, consistent equipment configuration and coordinated commissioning help simplify installation, operation and maintenance.
7. What experience does Yuantai Crane have with grab bucket cranes?
Yuantai Crane has engineering and manufacturing experience with grab bucket overhead cranes, double girder overhead cranes, bulk material handling cranes and waste handling lifting systems.
For garbage handling projects, Yuantai engineers review the crane bridge, grab bucket, hoisting system, travelling mechanism, control system, waste characteristics, working cycle and plant layout together before finalizing the crane configuration.
