To determine the "age" of a second-hand rotary drilling rig, it is not only necessary to look at the factory time, but also to combine the actual usage marks. Accurately identifying the service life can help you avoid severely aged equipment. The following six methods can be used as references:1. Ch Read More

The model of a rotary drilling rig is like its "ID card", carrying the core performance information of the equipment. Understanding the basis for model formulation can help users quickly determine whether the equipment is suitable for engineering requirements. Now, let's break down the key elements Read More

In the construction of rotary drilling RIGS, curved holes and skew are common quality problems, mostly caused by complex geological conditions and improper operation. If not dealt with in time, it may lead to consequences such as the inability to lower the steel cage and uneven force on the pile bod Read More

Groundwater is a common "roadblock" for rotary drilling RIGS during construction. If not handled properly, it can easily lead to problems such as hole collapse and buried drilling, affecting construction efficiency and safety. Mastering the methods to deal with groundwater is of vital importance for Read More

In the procurement of engineering equipment, second-hand rotary drilling RIGS have attracted much attention due to their cost-performance advantages. The timing of purchase directly affects the procurement cost and the subsequent usage value of the equipment. Grasping market rules and the characteri Read More
