The overhead crane for garbage disposal is with a garbage grab, which is import equipment in city waste incineration plant. Overhead crane for garbage disposal is installed over the garbage pit for garbage charging, transport, mixing and weighing. This garbage disposal grab crane can be manual, semi-auto and fully auto type, carrying out automatic grabbing, automatic repeat feeding, automatic repeat dumping, and automatic parking.
Due to the high working level of the garbage grab crane and the characteristics of the crane itself, it brings great challenges to the stable operation of the system. Our company has developed a new product through the accumulation of work in the lifting industry and summarizing the operation characteristics of the garbage grab. A set of frequency conversion speed regulation control method specially designed for garbage grab crane is proposed, so that the crane can run stably.
The crane handling system composed of two garbage grab cranes (one working and one standby) is used to complete the work of garbage feeding, stacking, mixing, moving and breaking of waste in the waste incineration power plant. Each crane has its own independent electrical control system, operation console and HMI display panel, and manual and semi-automatic control systems can be provided according to the needs of users. Hand, automatic switching is convenient and quick.
Manual Type:
Operator controls the crane with the linkage console.
Semi-Auto Type:
The grab operation is manual control, and the auto-controlled part includes the moving to charging port, weighing and charging.
Fully-Auto Type:
Once the crane receiving the charging signal from the charge port, the crane starts to do every move automatically, moving to the garbage, lower the grab, grabbing the waste, lifting the waste, moving to the charging port, weighing, charging, and returning the position. It will repeat the same motion automatically.
Basic Operation:
1. Feeding. Grab and feed Fermented garbage into waste incinerator.
2. Lifting and transport. Lift and transport the waste near the discharge door to avoid blocking the discharge door. Control the quantity of garbage in the waste pit to keep the inventory within 3~5d.
3. Mixing. Mix the garbage to extract water content and shorten the fermentation time, as well as keep safe of incineration.
4. Fetching. Fetch non-flammable objects in the pit.
5. Weighing. Weigh the garbage before being dump into the incinerator.
