1. PreambleIn the construction of bridges in hard geological areas, the commonly used pile foundation construction methods are hand-dug pile method and percussion drilling method. Manual drilling method is gradually eliminated due to the long pile construction period, backward technology, and the ne Read More

Only by making preparations for the transportation, assembly and disassembly of the rotary drilling rig and the positioning of the machine can we improve the drilling speed and prevent hidden dangers.What are the points of safe transportation?1.orientationBefore the upper board car, first understand Read More

The power head is the core component of a rotary drilling rig, responsible for providing rotational and lifting force to ensure efficient operation of drill rods and drill bits under various geological conditions. However, during construction, the power head may experience insufficient torque issues Read More

Rotary drilling rigs are advanced construction equipment widely used in foundation engineering projects such as bridges, buildings, and docks. Their efficiency and ability to adapt to complex geological conditions make them essential for deep foundation construction. However, to ensure smooth operat Read More

Desert environments are characterized by dryness, sand, strong winds, and significant temperature variations, all of which impose strict maintenance requirements on rotary drilling rigs. Without proper maintenance tailored to these conditions, equipment is prone to accelerated wear or even premature Read More
