AUTOMATIC GARBAGE GRAB CRANE FOR WASTE AND WASTE-TO-ENERGY PLANTS
The issue of overloading landfills is a significant problem for major cities today.
The daily waste generation in Vietnam is approximately 50,000 tons.
Urban areas account for about 35,000 tons per day, representing 70% of total waste, while the remaining waste comes from rural areas. In major cities like Hanoi and Ho Chi Minh City, the waste output ranges from 7,000 to 8,000 tons.
The predominant waste treatment method is landfilling, which accounts for 80% of the process, but it causes substantial pollution. It is important to note that the urbanization rate is about 30%, with over 1,000 urban areas nationwide.
The total annual waste output is 15 million tons, with 11.8 million tons of municipal waste generated annually.
Therefore, landfilling is no longer a sustainable solution in the current environmental conditions.
Vietnam has proactively collaborated with many countries such as Japan, South Korea, and European nations in adopting waste-to-energy technologies and methods for waste incineration to generate electricity.
In waste incineration technology, the waste handling process before entering the incinerator must ensure capacity, sorting, and continuity. Therefore, waste handling equipment such as the garbage grab crane plays a crucial role in this environment.
With the advancement of Industry 4.0, today’s automatic garbage grab cranes in waste-to-energy plants operate fully automatically, allowing the plants to function continuously without being affected by the environment, such as odors, toxic gases, and acids.
For waste-to-energy plants, special attention must be given to the following features when ordering automatic garbage grab cranes:
Sensor Technology:
- The automatic garbage grab crane must be equipped with 3D sensors, position sensors, and travel sensors. Typically, these sensors are produced by countries like Germany, the US, and Japan.
Weight Control Technology:
- The process of feeding waste into the incinerator must ensure the correct and sufficient quantity according to the requirements, with detailed reporting during operation. Therefore, the garbage grab crane must provide all necessary data reports to the control center.
Anti-Sway Technology:
- Anti-sway mechanisms must be particularly emphasized when using garbage grab cranes to avoid load swinging.
Operating Mode and Speed in Waste-to-Energy Plants:
The garbage grab crane in waste-to-energy plants must meet the A8/M8 working class (the highest class for industrial cranes).
Lifting speed: 50~70 m/min
Hoist travel speed: 70 m/min
Crane travel speed: 70~100 m/min
Depending on the incineration capacity of the plant, the garbage grab bucket overhead crane must be capable of handling from 500 tons/day to 1,000 tons/day.
The hoist design must be open-type: motor, gearbox, and brake are separate to operate in high-intensity, dusty environments with continuous operation.
The electrical power system for the garbage grab crane must utilize high-quality cables from reputable countries.
The garbage grab bucket used in waste-to-energy plants is a hydraulic electric grab bucket. It opens and closes hydraulically and operates fully automatically from the control center.

The link between the grab bucket and the crane’s hoist must ensure anti-twist, especially measures to prevent rotation of the grab bucket.
Key Components for Garbage Grab Bucket Overhead Cranes:
Lifting motor: SIEMENS
Gearbox: Sumitomo, Bonfiglioli
Hydraulic brake: South Korea, France, Germany
Steel cables: South Korea, Japan, Thailand
Grab bucket: South Korea, Germany, Italy
Automatic control system: Beckhoff, Sick, Mitsubishi, Siemens
Operational Notes:
The garbage grab crane in waste-to-energy plants must always be ready. Therefore, every project must always have one operational crane and one backup crane.
Spare equipment must always be ready to replace faulty components, ensuring the garbage grab crane remains in working condition.
In response to these equipment requirements, VINALIFT has successfully provided numerous automatic garbage grab crane projects for waste-to-energy plants worldwide.
As an experienced manufacturer of garbage grab cranes, VINALIFT is undoubtedly the right choice for contractors worldwide looking for reliable equipment for waste-to-energy projects.
