Grab Crane Waste Crane And Garbage Overhead Crane For Wastes Management

Wastes management, grab crane, waste crane, or garbage crane is a heavy duty overhead crane equipped with grab bucket, which is used to handle refuse incineration facilities, and machines for refuse-derived fuels, and for sorting and recycling. The semi-automatic grab crane for waste handling is the core equipment of the municipal solid waste incineration plant's garbage supply system. It is located above the rubbish storage pit and mainly takes charge of the feeding, handling, mixing, taking and weighing of garbage.

Features of Garbage Disposal Overhead Crane

1. High lifting height with anti-sway operation. 2. Real-time dynamic measurement. 3. Grab status monitoring, fault diagnosis alarm and report statistics. 4. Adapt to harsh working conditions: high temperature, Humidity, more Dust and Gas corrosive. 5. Heavy work load: average 8,000h working time per year, High load rate, high work frequency. 6. Reliable work: less failed, guarantee smooth production. 7 .Strong beams: The crane beams are of welded construction,this result in lower dead weight with a high degree of vertical and horizontal rigidity and smaller wheel loads. 8.. End carriage: Crane travelling system,motor-reducer wheel driven system! Motor used soft start motor which result in very stable starting!

advantages

Feeding When the garbage in the incinerator inlet is insufficient, the crane grabs the fermented garbage in the garbage pit and runs it to the top of the feed inlet to feed the feed hopper of the garbage incinerator. Handling The waste near the discharge gate is transported by garbage grab crane to other places in the pit, avoiding the jamming of the discharge gate, adjusting the amount of waste in the pit, and storing it for 3 to 5 days. Stirring Due to the high domestic water content of domestic waste and the low combustion value, garbage needs to stay in the storage pit for a certain period of time. Through natural compression and partial fermentation, the water content is reduced and the calorific value is increased. The mixing of old and new garbage can shorten the fermentation time. In addition, due to the complex composition of domestic garbage and large variations in the content of ingredients, in order to avoid excessive fluctuations in the nature of incoming waste, it is also necessary to carry out necessary agitation and mixing of the refuse in the pit. Picking Inadvertently enter the pit, but it is not suitable to remove the incinerated object. Weighing In order to count the actual incineration amount of garbage, before the garbage is put into the inlet of the incinerator, the garbage input to the inlet is weighed and measured by garbage grab crane. Due to the high level of work of the garbage grab crane and the characteristics of the crane itself, it brings great challenges to the stable and reliable operation of the system. Our company has developed and summarized the operational characteristics of garbage grabs in the work of the lifting industry and developed A frequency conversion speed control method designed for garbage grab cranes was designed to enable the crane to operate stably and reliably. A crane handling system consisting of two garbage grab cranes (one work and one spare) is used to complete the garbage loading, dumping, mixing, material transfer, and breaking of materials for garbage incineration power plants. Each crane has its own independent electrical control system, operation console and HMI display panel, which can provide manual and semi-automatic control systems according to the needs of users. Hand, automatic switching is quick and easy.
