300H

• The rotary head is equipped with three reducer motors, with large torque, high speed, and strong rock entry capacity.
• The hydraulic system is provided with load sensing technology plus total power and limiting power control technology, rendering higher efficiency and saving more energy. A large-flow pump valve is adopted so that the main winch is lifted and lowered rapidly, with high construction efficiency.
• The newly optimized pipeline layout reduces pressure loss, enlarges the space, and facilitates maintenance. The drilling mast transition pipeline is arranged in a single row to prevent wear between oil pipes.
• The slewing brake technology of patent platform applied for rock entry working conditions, in conjunction with drilling masts made of high-strength materials, wide and large double-boom luffing mechanism, and new reinforced special extendable chassis, enables high fatigue resistance and long service life.
• A large-diameter roller is used to realize single-layer winding of steel wire rope under full drilling depth, increasing the service life by 50%.
• Concealed auxiliary outriggers at the bottom of the mast can assist in the placement of the hole casing and facilitate the maintenance of the chassis.
• Fault self-diagnosis alarm, real-time display of control parameters, and dedicated one-key locking of the electromagnetic handle save work and efforts of operation; Sunward Cloud mobile APP realizes synchronous transmission of construction data and real-time monitoring of equipment status.
• It can be equipped with the industry's pioneering wireless remote control device to realize remote control trawling, luffing, and other functions. Under special working conditions, it is placed "outdoors", so the field of vision is wider to ensure safety.
• Its machine functional extension and strong technical practicality can realize multiple functions of one machine. It can be used for the construction of CFA long spiral drilled press-grouting pile, visible and controllable enlarged bottom cast-in-place pile, and large-diameter non-uniform piles. It can be modified into DTH hammer for construction and equipped with slewing joint device, which can realize the reverse circulation and efficient rock entry of extra-large-diameter and ultra-deep hole DTH hammer.
• This model won the Gold Award for Market Performance and Start Product Award of the top 50 China construction machinery annual products in 2020.
