grab crane also called grab bucket crane is a lifting device for waste and garbage management in garbage incineration plant, which is also named waste crane or garbage crane. The grab crane is a type of overhead crane, mounted on top of the waste storage pit, mainly responsible for garbage feeding, handling, mixing, extract and weighing.
According to different standards the grab crane can be classified into the following type generally:
Single girder grabe crane for log handling
Single Girder Grab Crane is lightweight grab bridge crane supporting the use of grab trolley, divided into general type and hanging type, lifting mechanism is optional electric hoist grab. Applicable to tunnel, corridor, etc. and the places with small space, low height and limited conditions, widely used in railway stations, coal yard, warehouse, construction site, thermal power waste plant, biomass power generation coal washing, slag and many other industries.
Double Girder Grab Crane is developed and evolved from double girder bridge crane, suitable for metallurgy, steel mills, brewing, building materials, chemicals, coal and other industries or outdoors across fixed span, engaged in minerals, steel scrap, wine tank, slag, coke, coal, sand and other parts or granular materials lifting and handling work. Equipped with rain-proof device during outdoor operation. It belongs to heavy duty, lifting capacity including the weight of the grab.
Grab is a kind of hoist lifting spreader which can grab varieties of bulk materials, divided into four rope type, double rope type, single rope type, electric type, discs type, shear type, hydraulic type and log type, etc.
Crane spreaders for grab cranes: Single rope grab, Double rope grab, Four rope grab
Single rope grab apply to the crane only have one lifting reel, freely opened and closed during loading and unloading of bulk materials, the whole crane is easy to use and disassembly, suitable for underwater operations grab and stack. Single rope grab unable to open in the air, hand and remote control type can be realized to open in the air.
Suitable for double hoisting mechanism crane, apply to grab all kinds of loose debris. Two hoisting mechanisms, one is responsible for grab lift, another is for grab opening and closing.
With good strength, light weight, reasonable structure, material grab finer and smaller. Blade plate using special wear-resistant plate, enhancing the degree of impact and friction, multi-layer sealing process using on pulley, dust and water can be operated underwater, blade plate seam gap is small which can reach 0.3mm, can maintain a cleaner workplace, the overall structure is not easy to deform, four rope grab can also be designed to double rope grab.
Crane spreaders for grab cranes: Electric stainless steel grab Log crane , Scissor Grab
Designed specifically for the brewing industry, grab help brewing koji, sauce, and sauce making, etc., reduce the labor intensity of the workers, is conducive to the clean and sanitation of production floor.
It is suitable for lumber yard, large wood products factory, paper mills, ports and other industries, for loading and unloading, stacking. The structure is divided into four types: single rope, double rope, four rope and electric type. It can be also designed and manufactured according to your needs.
Scissor Grab relies on wire rope retractable to close and open the grab jaw. its closing moments increased gradually during closing process, does not leak and clean material when crawling materials, mostly used for ship unloader.
Design and manufacturing according to FEM / DIN standard, import the main hydraulic components. Big Grasping force, high degree of automation, it is ideal handling tools for large pieces of ore, pig iron, scrap, waste, iron, straw, slag and other materials. It is mainly used in iron and steel, mining, forest farm, coal mining, harbor dock, scrap steel acquisition, garbage disposal, bioelectrogenesis and other industries.
Depending on different industries, using occasion and the grab materials, electro-hydraulic grab divided into discs type and two discs type. Orange Discs type is divided into circular and rectangular, its claw including closed, semi-open and open type.
