When it comes to 'piling experts' in construction engineering, the rotary excavator is definitely an indispensable piece of equipment. Perhaps some newcomers might ask: Isn't it just drilling a hole and pouring a pile? Can't ordinary drills do that too? Why is the rotary excavator always the first c Read More

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

In the construction of second-hand rotary drilling RIGS, the verticality of the borehole directly affects the project quality, and this requires a close coordination between the performance of the accessories and the operation specifications. The following breaks down specific guarantee methods from Read More

In the construction of rotary drilling RIGS, the drill bit is the core component. The drill bits of second-hand rotary drilling RIGS, due to their longer usage time, are more prone to wear and tear. If new drill bits are directly replaced, the cost will increase. However, reasonably repairing and re Read More
