129829717139843750_5Introduction to left and right combination of grab bucket or multiple jaw opening crawl and Sling for unloading bulk materials, made up of more than one jaw grab is also called gripper. Grab classification by shape classification by shape and orange can be divided into the bell-shaped grab grab, which is made up of two full buckets, which are composed of three or more's jaw. Classification in the drive way driveCan be divided into hydraulic grab bucket and two kinds of mechanical grab.
Diablo 3 CD-KEY, Hydraulic-hydraulic grab-grab itself with retractable structure, usually driven by hydraulic cylinder, made up of more than one jaw hydraulic grab bucket-also called a hydraulic claw.
Hydraulic grab broader application in the special device for hydraulic, hydraulic excavators, hydraulic lifting Tower. Special hydraulic excavator grab into Rotary andTurn two, without rotating clamshell excavator bucket cylinder oil, without adding hydraulic valve block and pipe; with rotary hydraulic valve block and grab to add a pipeline to control.
Special hydraulic excavator grab for application: 1, building the foundation of deep Foundation pit excavation, trenching and soil, sand, coal, gravel loading. 2, suitable specially in the ditch or restrictedMining and loading space on one side.
3, suitable for loading and unloading of ships, trains, cars.
-Mechanical, mechanical grab grab the second closing itself has no configuration structure, usually made of rope or rod driven by external force
SWTOR Credits, operating characteristics and can be divided into two-rope grab single rope grab, the most commonly used is the double rope grab. Double support ropes and rope grab closing rope, respectively around supportReconstruction and opening-closing Agency on drums. Figure 1 is a double rope grab: a is the support ropes and falling while closing rope, open mouth insert pile. B closing rope tightening, jaw closed merge to crawl the material. C is the support ropes and after closure of grab closing rope at the same time increase. D to support ropes fixed, closing rope drop, mouth open and remove the material. Reliable double rope grab operationSimple, high productivity, widely used.
With two sets of double rope becomes a four-rope grab, work processes with the same double rope grab. Support ropes and single rope grab closing rope with the same wire rope. Through special locking device so that the rope turns from role to support and close.
Single rope grab winding mechanism is relatively simple, but low production rate, when a large number of loading and unloading operations are rarely used. GrabAccording to the density of crawled items are divided into light (such as grabbing cereals), medium (such as crawling grit) and heavy (such as grab iron ore) of class 3; number of jaw and jaw is divided into two-jaw grab grab, the most common is two-jaw grab. For lump ore, scrap iron and scrap steel multi-jaw grab should be adopted, because it has the characteristics of claw, cuts a sharp, easy to insert materialTo get better crawl effect. Also has a imitation scissors structure principle of cut type caught bucket (Figure 2), it of crawl force can with jaw Board of closed and gradually increases, in closed ended Shi reached maximum value; its bucket mouth of open of and cover material of area also than General caught bucket for large, improve has crawl ability, conducive to cleaning material field and cabin, but for large material due to its initial crawl force smallAnd less effective. Hydraulic grab bucket made of hydraulic grab is a product of hydraulic structure, consists of a hydraulic cylinder, bucket (jaw), connection column, ear, ear covers, bucket teeth, tooth, comprising spare parts, hydraulic grabs for welding is the most critical manufacturing processes, welding quality directly affects the structure of hydraulic grab strength and service life. Hydraulic cylinders are also the most criticalDrive units. Hydraulic grab bucket is a dedicated industry equipment parts, requires special equipment to efficient, high quality jobs, such as: CNC plasma cutting machine Groove milling machine, boring machine, bending machine
