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 drill pipe of a rotary drilling rig is the core component for transmitting torque and axial force. As two mainstream types, the machine lock rod and the friction rod have significant differences in structural design and applicable scenarios. Understanding the differences between the two can help Read More

As the "underground pioneer" in infrastructure projects, the rotary drilling rig's traveling part bears the weight of the entire machine and enables operation movement, which is a key link to ensure construction efficiency. However, during long-term high-intensity operations, the components of the w 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

As the core equipment in foundation engineering, the construction efficiency of rotary drilling RIGS is directly related to the project progress and cost control. However, in actual operation, multiple factors will work together, causing the equipment to fail to perform at its best. Understanding th Read More
