Description

The DR-285 rotary drilling rig is a versatile and powerful solution designed for small to medium-sized projects. Engineered with a friction type and mechanical locking drill pipe system, this rig ensures exceptional stability and reliability, thanks to its robust KOMATSU chassis. This multi-purpose rotary pile driver is capable of performing effectively in various working conditions, making it an ideal choice for diverse construction needs.

Equipped with options for Weichai or Cummins engines, a Kawasaki hydraulic system, and a DOOSON rotary drive reducer, the DR-285 provides flexibility and efficiency on the job site. It is compatible with various drill bits tailored to specific construction environments, allowing for adaptability based on project requirements. For instance, contractors can start with a spiral drill for concrete surfaces and follow up with a barrel drill for sandy layers. In harder soils, the rig’s capability to inject water with a small-diameter two-way open-tube drill bit enhances its functionality, achieving the desired depth before expanding the hole width as necessary. Furthermore, the Kelly bar drill rod can be customized to meet individual customer specifications.
