The bucket features a large soil inlet combined with an open shell structure, allowing excavated material to enter and discharge more efficiently. This design minimizes clogging, improves spoil removal, and significantly increases drilling efficiency, especially in cohesive soil conditions.
Manufactured from high-strength alloy steel, the bucket body is reinforced with wear-resistant ribs and guide plates to withstand heavy impact and abrasion. The robust construction extends service life, reduces maintenance frequency, and delivers reliable performance in demanding construction environments.
Specially designed guide strips reduce the vacuum effect generated during drilling, preventing the bucket from becoming stuck or difficult to lift. This feature ensures smoother drilling cycles, improves operational stability, and reduces unnecessary wear on both the drilling tool and the rotary drilling rig.
The optimized bucket geometry and cutting layout provide efficient soil penetration with lower drilling resistance. The open-bottom design enables faster unloading, helping contractors improve productivity and shorten project completion times.
The Open Bottom Drilling Bucket is suitable for a variety of geological formations, including:
It is an ideal drilling tool for foundation engineering, bridge construction, highway projects, railway infrastructure, and high-rise building foundations.
The bucket is equipped with replaceable cutting teeth and wear-resistant components, making routine maintenance quick and cost-effective. Replacing worn parts instead of the entire bucket helps reduce operating costs and maximize equipment uptime.
Designed to fit most leading rotary drilling rig brands, including SANY, XCMG, Zoomlion, BAUER, Soilmec, Casagrande, IMT, MAIT, and Liebherr, with customized Kelly box dimensions available upon request.
Different bucket diameters, shell lengths, cutting tooth configurations, and Kelly box sizes can be customized according to customer requirements, ensuring optimal performance for specific drilling conditions and equipment.
