Address:Industry Park, Changyuan, Henan, P.R.C


Garbage Grab Crane is the core device of garbage incineration plant feeding system; it is grab overhead crane, mounted on top of the waste storage pit, mainly responsible for garbage feeding, handling, mixing, extract and weighing.
Feeding: When incinerator feed port is insufficient of garbage, crane grab fermented garbage in the garbage pit and run to the above of the feed port to feed the filling hopper of the garbage incinerator.
Handling: Transported the garbage close to discharge door to the storage pit, avoid congestion of the discharge door, regulating the garbage amount in the pit.
Mixing: In order to improve the speed of garbage fermentation and garbage composition homogeneous combustion, necessary stirring and mixing of garbage in the pit is needed.
Extract: Removed the object of unfavorable incineration. e.g.: Take large garbage out, put it into the crusher for crushing and then feeding, which avoid feeding port congestion.
Weighing: For statistical actual amount of garbage incineration, weighing the garbage before put it into the incinerator feed port.

Garbage Grab Crane

Weihua Crane is professional material handling equipment manufacturer and servicer with largest production in global. Provide you with overhead crane, gantry crane, electric hoist, etc. of safe, reliable and efficient crane solutions and services.


Garbage grab crane with high working requirements, including the following specifics:
Operation under harsh environment: high temperature, high humidity, dusty and strong corrosive gas.
Heavy workloads: long working hours, high full load, frequent work.
Maintenance difficulties: poor working conditions, a variety of harmful gases garbage rotting increased difficulty of the work.
High reliability: If unable to compensate in crane failure, which will affect the incinerator feed, resulting in garbage incineration plant shutdown.
According to the above requirements, Garbage Grab Crane components have the following strengthened features:
Box girder connected with end beams by high-strength bolts, it is with lightweight structure, strong anti-fatigue capability, high precision assembly and convenient in manufacturing, installation and transportation.
Electrical Device
Garbage Grab Crane using powerful logic operation functional controller-PLC control (programmable logic controller), drive use frequency control, control the lifting, trolley and crane three structures, to make them traveling smooth, stopping accurately. Crane and trolley power supply and control cables using cable pulley.
Crane traveling Mechanism
Adopt respectively driving form, wheels and the "three-in-one" drive unit are mounted on the end beam; consisted of hardened reducer, brake and motor. Driving form has characteristics of high transmission precision, light weight, good sealing, low noise and maintenance free. Equipped rotary encoder on the driven wheel set connected to the PLC.
Trolley traveling mechanism
Adopt centralized drive arrangement, "three-in-one" drive device. Driving form has characteristics of high transmission precision, light weight, good sealing, low noise and maintenance free. Equipped rotary encoder on the driven wheel set connected to the PLC.
Main lifting mechanism
Motor drive the wire ropes on the two rolls through hardened reducer to grab spreader, rope spacing with wide above and narrow below, that makes the grab with anti-swing features, which can stop at accurate position.
Weighing Sensor
Mounted on the reel bearing support, with overload alarm function, load reaches 90% by rated, issued with reminder alarm; when the load reaches 110% of rated, issued with alarm and stop the crane; weighing system uses computer measurement to print report and automatically measure the net weight of load.
Control mode
Electric control operations concentrated in the fixed control room, with manual control and semi-automatic control mode, when the semi-automatic control, it can automatic repeat inverted stack, feeding and other processes. And with monitoring system monitoring the operation work on real-time.
In addition to have brake device, limit protection, electrical safety protection and other protection measures as the same as general double girder bridge crane, garbage grab crane also has the following technical specifications
1. Regional protection measures. The Crane can only move within a set range; within a specified area during unloading garbage, grab is not allowed staying.
2. Measures to prevent grab hit the wall of the garbage pit.
3. Slack rope prevention means is provided, when the rope slack, in order to prevent grab tilting, turning off the grab dropping.
4. Wire rope with anti-winding device.
5. When power failure, grab cannot open on its own.
6. Lifting mechanism with overload protection and detection device, after the grab action is completed, testing equipment automatically check whether it is overweight of the garbage, such as overweight, if it is overweight, the grab unloading it and re-grab.
7. Automatic weighing and recording function.
8. With motor overheat protection device.
