Municipal Solid Waste Handling Cranes

Waste Power Station Double Girder Grab Crane

Kinocranes Domestic Garbage Crane is a crane dedicated to waste incineration power plants. Adopting the intelligent identification technology independently developed by our company, it can realize manual, semi-automatic and fully automatic control modeThe full-automatic mode can not only intelligently identify the height of the reclaiming point, intelligently level the material pile, but also control the process sequence, automatically control the operation of the garbage crane, and complete all the processes such as incinerator loading and domestic waste material yard reclaiming, stacking, and mixing. process. At present, domestic garbage cranes have made standardized designs, which can realize the overall processing and assembly line production of domestic garbage grab cranes.

Technical Data

MSW Handling Cranes Features

1. Bridge: The semi-deviated box-shaped main beam is welded to the end beam and transported in the middle section of the end beam. The trolley track is connected to the main beam with a pressure plate. When the track is worn, the track can be easily replaced.

2. Long travel trolley driving mechanism: adopting separate driving arrangements, the wheel set and the "three-in-one" drive unit are installed on the end beam, and the "three-in-one" drive unit adopts German Flanders products. Composed of brake motor.

3. Trolley: 1 motor drives 4 steel ropes on 2 reels to lift 4 lifting points hydraulic grab buckets through 2 hard toothed surface reducers. The reducer and the reel are connected by a reel coupling, which reduces the requirements on the installation accuracy of the reel and the rigidity of the small frame, and improves the life of the low speed shaft seal of the reducer. The trolley is double-layered, which improves the weighing accuracy. The trolley uses the "three-in-one" transmission produced by Flanders, and a position encoder is installed on the driven wheel axle.

4. Grab bucket: 4 hanging points multi-lobed hydraulic grab bucket, hydraulic center imported from Germany, and driven by 380 V AC voltage. The power supply of the grab bucket is synchronized with the hoisting drum and is arranged on the trolley.

5. Weighing system: The computer measures and prints the report. The weighing sensor is installed on the roll bearing seat. The weighing system also has the function of overload alarm and automatic peeling.

6. Power supply: cable trolley power supply system is used for both large and small cars.

7. Control method: The electric control operation is concentrated in the fixed control room, and manual control and semi-automatic control are used. During semi-automatic control, the processes of stacking and feeding can be automatically repeated.

8. Electrical control: adopts a programmable logic controller (PLC) with powerful logic operation function. The drive uses AC frequency conversion to regulate the speed, which can make the hoisting, trolley, cart and other institutions run smoothly and accurately. The three-dimensional coordinate detection is adopted. Encoder indirect addressing mode. The operation adopts master command control or touch screen. The level of automation is high.

Grab Crane Applications

Domestic Garbage Crane Selection

1. Waste incineration power generation treatment process (the treatment process of waste incineration power generation currently has two types: fluidized bed treatment and grate furnace treatment);

2. Quality of domestic waste (water content, calorific value, ash content);

3. Disposal volume of domestic garbage (considering the growth rate of domestic garbage and the subsequent transformation of the waste incineration power generation system);

4. The characteristics of the garbage pool (single pool or double pool);

5. Number of garbage grab cranes (not more than 3 garbage ponds);

6. Whether there is domestic garbage sorting and crushing process (there is no sorting and crushing process that has a great impact on the efficiency of the garbage grab crane);

7. Grab volume. According to the design specifications of waste incineration power generation engineering, the number of garbage grab cranes has the following regulations: a waste incinerator power plant with less than 200T / D uses a garbage grab crane. Waste incineration power plants with a capacity of more than 200T / D and less than 800T / D use two garbage grab cranes. More than 800T / D waste incineration power plants use three garbage grab cranes.

With the increasing number of domestic waste incineration power generation system construction and renovation projects, the scale of treatment is also increasing. The choice of garbage grab crane should be considered in order to ensure the convenience and reliability of the operation of the waste incineration power generation system in the future. In order to facilitate the selection of the waste incineration power generation system, the domestic garbage grab cranes provided by Henan Kinocranes, mainly include 5t, 6.3t, 8t, 10t, 11t, 12.5t, 15t, 16t, 18t, 20t and 25t.
