Hydraulic hole digger : TRH
Hydraulic Hole diggers for excavators up to 8 tons or telescopic handlers.
Ideal for public works and outdoor landscaping, hydraulic augers from the TRH range are suitable for all hydraulic equipment such as mini-excavators from 0.8 to 8 tons, compact loaders, wheel loaders, backhoes, or telescopic handlers through a universal quick coupler.
Driven by a hydraulic motor, the TRH auger operates with two hoses: pressure and return, requiring no drainage, for a drilling equipment that allows for quick and cost-effective setup! The compact motor block allows it to penetrate up to the coupling hitch for deep drilling without the need for an auger extension.
Mounted on a suspension cardan, the hydraulic auger is pendular, allowing for a well-vertical drilling despite slopes.
Designed to adapt to all types of construction sites: drilling soils, foundations, post and fence installation, plantations… the hydraulic auger on a mini-excavator offers a wide range of augers from 100 to 600 mm in diameter.
Robust, the thickness of the spiral is the same throughout its length. The assembly is continuously welded above and below for maximum reliability. Its upper part features an interchangeable centering pilot.
These augers are mounted on the drilling auger through a hexagonal coupling hitch allowing for easy and fast changes without requiring tools.
Robust and powerful, TRH augers guarantee high reliability and quality work!
