Autumn has arrived. The editor invites you to follow in the author's footsteps and appreciate the elegance of CRRC Beijing Heavy Industry's TR400 and 460F rotary drilling rigs.
The TR400F rotary drilling rig adopts the CAT349 chassis, and the TR460F rotary drilling rig adopts the CAT374 chassis. Caterpillar Inc. is the world's largest manufacturer of construction machinery and equipment. Its construction machinery chassis features high reliability, high efficiency, and convenient after-sales maintenance. The CAT chassis is compact in structure and more compact than chassis of the same model from other manufacturers, making it easier to meet construction requirements in special spaces. The advanced load-sensing control technology enables optimal matching under different working conditions, making control intelligent and improving the working efficiency of the drilling rig.
Both the TR400F and TR460F rotary drilling rigs adopt a rear-mounted main winch with dual motors, dual reducers, and a single-layer large drum design. The drum is jointly driven by two reducers and two motors through a drum-shaped gear coupling, avoiding the "rope biting" phenomenon of double-layer winding. Both the TR400F and TR460F rotary drilling rigs adopt a large triangular support structure, which reduces the slewing radius and enhances the construction stability of the drilling rig.
Both the TR400F and TR460F rotary drilling rigs adopt a patented hole depth measurement device, improving depth measurement accuracy.
The TR400F drilling rig adopts a wire rope pressurization method with a pressurization stroke of 14 meters. It has high pressurization force and a long pressurization stroke, facilitating the installation of casings. The TR460F drilling rig can meet the requirements of extra-large piles and rock penetration.
The TR400F and TR460F rotary drilling rigs are upgraded products based on the company's TR400D and 460D products. The new models continue the mature design and process technology of previous rotary drilling rigs in the main winch system, hydraulic system, and cab, maintaining the advantages of the TR400F and TR460F rotary drilling rigs, such as good power performance, high production efficiency, and good economic benefits. The product upgrade includes quality improvement designs for the overall appearance, operating comfort, cab sealing, and noise reduction, resulting in a significant overall performance improvement.
It is precisely because CRRC Beijing Heavy Industry has always prioritized the needs of frontline users over the years and practiced the marketing service philosophy of "only by creating value for customers can we create value for ourselves" that it has been recognized by a wide range of users and has loyal users who firmly choose only CRRC Beijing Heavy Industry products.
