TG50 Diaphragm Wall Grab

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.

TG50 type diaphragm wall grabs are highly hydraulic controlled, easy to relocate, safe and comfortable 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.

Frequently Asked Questions
Q1: What are the main applications of the TG50 diaphragm wall grab?
A1: The TG50 is primarily used in deep foundation engineering for constructing water-resisting and bearing walls in projects such as metro stations, high-rise building basements, underground parking, underground business streets, ports, mining, and reservoir dams.
Q2: What type of chassis and key components does the TG50 utilize?
A2: The TG50 is built on a special CAT chassis and incorporates high-performance Rexroth valves, pumps, and motors, ensuring excellent operational stability, efficiency, and reliability.
Q3: How does the calibration and rectification system of the TG50 work?
A3: The TG50 is equipped with a 1-cylinder connecting rod (push plate mechanism) and a 2-cylinder connecting rod (4-rod mechanism) zero adjuster, allowing the arm to be calibrated at any time. It also features inclinometers, along with longitudinal and lateral rectification devices for effective correction in soft soil layers.
Q4: What are the performance capacities of the TG50 in terms of wall depth and closing force?
A4: The TG50 has a maximum wall depth capability of 80 meters, a wall thickness range of 0.8 to 1.5 meters, and delivers a powerful grab closing force of 120 tons, making it highly effective in complex strata.
Q5: What measurement system is installed on the TG50 for accuracy?
A5: It features an advanced touch-screen computer measurement system that records and displays parameters like dug depth, hoisting speed, and coordinates (X, Y direction). The system can measure inclination degrees up to 0.01 accuracy, which can be saved, printed, or output.
Q6: Does the TG50 allow construction at different angles?
A6: Yes, the TG50 is equipped with a grab rotary system that enables relative boom rotation. This allows the operator to complete wall construction at any angle even when the chassis remains stationary.
