In the process of foundation construction, the drilling depth and diameter of the rotary drilling rig are the key indicators determining the suitability of the project. These two capabilities are not fixed values but are the result of the combined effect of equipment model, geological conditions and Read More

During the infrastructure boom of skyscraper construction and extended transportation networks in cities, the "environmental friendliness" and "efficiency" of construction equipment have gradually become the core standards for evaluating engineering quality. Traditional drilling equipment of Read More

Second-hand rotary drilling RIGS, due to their long service life and high frequency of parts replacement, often face problems such as high prices and delayed supply of imported parts. With the upgrading of domestic manufacturing technology, many components have achieved reliable domestic sub. Read More

The operation records of second-hand rotary drilling RIGS are not merely "running accounts", but rather the core basis for equipment condition monitoring, maintenance planning and construction efficiency optimization. By standardizing records and applying them reasonably, not only can fault risks be Read More

Second-hand rotary drilling RIGS, due to their long usage time, have a higher probability of component aging or wear. During construction, they are prone to problems such as stuck drill and insufficient power. If not dealt with promptly, it may lead to equipment damage or project delays. The followi Read More
