TG70 Hydraulic diaphragm wall grabs

The TG 70 hydraulic diaphragm wall equipments are underground structural elements principally used for retention systems and permanent foundation walls. As a result of their undoubted strength, simplicity and low runningcost, our TG Series cable-operated grabs for diaphragm Walls are widely used in the construction of foundations and trenches. Rectangular or semicircular jaws with their relative guides are interchangeable on the actual grab body. Unloading is done by taking advantage of the grab body’s weight. When released by the rope, the grab descends with considerable force, thus helping unload material from the jaws.

• Stability undercarriage
• Adopting the Hyundai chassis from South Korea, the quality is stable, the performance is reliable, the cabin space is spacious, and comfortable.

• International standard Key parts
• The winch reducer are selected from Germany’s Zolon, equipped with Rexroth motors and balance valves, ensuring stable quality and high efficiency of the winch; The walking reducer adopts Brevini brand and is equipped with a German Rexroth walking motor;

• Hydraulic system
• The main pump uses Kawasaki hydraulic system, which increases efficiency by 20%, has high efficiency, and saves energy consumption
• The hydraulic isolation system with innovative design for environmental protection and emission reduction separates the main hydraulic system from the hydraulic system of the opening and closing bucket. Even if the hydraulic system of the opening and closing bucket is contaminated by mud, it will not affect the main hydraulic system. The only contamination is the hydraulic oil in a section of the closed circuit pipeline, reducing the treatment of contaminated hydraulic oil

• Excellent performance
• Super II (III) type bucket head. The capacity of the bucket has increased significantly, resulting in a large excavation capacity and high excavation efficiency. Suitable for construction in complex geological formations, with a long service life; Wall brushes can also be configured for convenient construction. Configure a hydraulic impact excavation device that can impact the surrounding flow.

• Multi functional heavy-duty impact bucket body with strong compatibility.
• On the basis of the original H800 grab bucket, the upgraded heavy-duty HDC800 multifunctional bucket body can be compatible with bucket heads that were previously widely circulated in the market;
• The mast lifting structure is convenient and fast. T The mast lifting device of TG70 equipment has been redeveloped and designed. When transported and disassembled, it can be placed on the mast without any disassembly work. The operator can lift and place the mast by sitting alone in the cab, making mast lifting convenient, reducing labor intensity, and ensuring safety and reliability;

• Powerful correction push plate system
• The stiffness of the push plate increases, making it less prone to deformation; More reasonable structure and greater thrust; Long journey, good correction effect; Larger space, less likely to get stuck during construction with gravel, pebble, cement blocks, etc;

• Intelligent control
• Device data management. The touch screen computer in the driver’s cab monitors, displays, records and stores various data during the construction process in real time; The inclination trend of the bucket body in the X and Y directions; Various pressures, lifting and lowering speed of the winch, collision of the opening and closing bucket (with optional hydraulic isolation system), weight of the grab bucket, depth of excavation, depth of footage, inclination angle of the mast, status of the slewing brake, and display reminders for problems.
