General Introduction of TG 50 hydraulic diaphragm wall grabs
TG 50 hydraulic diaphragm wall grabs are current main equipment of diaphragm construction, and it has advantages including high efficiency construction, accurate measurement, and high quality of wall. It is mainly used in the construction of water-resisting wall, bearing wall in deep foundation engineering of large-scale construction and projects, such as metro station, basement in high rise building, underground parking, underground business street, port, mining, reservoir dam engineering and others.
Our TG50 type diaphragm wall grabs are highly hydraulic controlled, easy to relocate, safe and conformable to operate, excellent in working stability and highly cost effective. In addition, TG series hydraulic diaphragm wall grabs build the wall rapidly and requires small amount of protective mud, especially suitable for operations in areas with high urban population density or close to the buildings.
TG TG50 type diaphragm wall grabs are designed with innovative push-plate alignment system having greater structural superiority, the homing of grabs are easier and faster. With 1-cylinder connecting rod (push plate mechanism) and 2-cylinder connecting rod (4-rod mechanism) zero adjuster, the arm can be calibrated at any time in progress.

Advantages of TG50 Diaphragm wall garbs
1. TG50 Diaphragm wall garb with 1-cylinder connecting rod (push plate mechanism and 2-cylinder connecting rod (4-rod mechanism) zero adjusters, the arm can be calibrated at any time in progress;
2. TG50 Diaphragm wall garb has high-efficiency construction and a powerful grab closing force, which is beneficial to construction of diaphragm wall in complex strata;
3. Hoisting speed of winding machine is fast and auxiliary time of the construction is short;
4. Inclinometer, longitudinal rectification and lateral rectification devices are mounted can make the bearing conditioning for slot wall and can have a good rectifying effect in the construction of soft soil layer;
5. Advanced measure system: the grab has equipped advanced touch-screen computer measure system, recording and displaying the dug depth and inclination of hydraulic grab bucket. Its depth, hoisting speed and location of X, Y direction can be displayed accurately in the screen, and its measured inclination degree can reach 0.01, which can be saved and print and output automatically by computer.
6. Grab rotary system: grab rotary system can make relative boom rotary, under the conditions that the chassis cannot be moved, to complete the wall construction at any angle, which greatly improve the adaptability of equipment
7. TG50 Diaphragm wall garb has advance- performance chassis and comfortable operation system: using special chassis of CAT, valve, pump and motor of Rexroth, with advance performance and easy operation. The cabin equipped with air condition, stereo, full adjustable driver seat, with features of easy operation and comfort.
