Daily operation, maintenance and maintenance of truck cranes

The rotation rig is a construction machinery that is suitable for hole -forming operations in the basic engineering of the construction. It is widely used in infrastructure construction projects such as municipal construction, highway bridges, high -rise buildings and other places, and cooperate with different drillings, which are suitable for hole -forming operations of dry (short spiral), wet type (rotation) and rock formation (rock diamond). The rotary rig drilling machine is mainly suitable for the construction of soil layers such as sand, viscous soil, and powder soil.

 It is widely used in various foundation infrastructure such as irrigation piles, continuous walls, and basic reinforcement. The rated power of the rotor rig is generally 125-450kW, the power output torque is 120-400kn · m, the maximum hole diameter can reach 1.5-4m, and the maximum hole depth is 60-90m. Essence The rotary rotor drilling machine has the characteristics of large installed power, large output torque, large axial pressure, flexible maneuverability, high construction efficiency and multi -function. It has been widely used in various drilling pile projects. Construction process: The rotary rotor drilling rod adjusts the drill rod, combined with the drill head to cut into the soil layer, and then the drill tube lifts up the soil, and finally pores.

Scope of application: 

(1) Suitable for various soil layers, sand layers, pebble layers, etc., which have the characteristics of fast pores, convenient movement, and small environmental pollution, low noise.

(2) The construction difficulty of the rock layer is relatively difficult, and due to the limitation of the drill rod length, the pile length and the pile diameter will be greatly limited.
