Concept and characteristics Kelly rope Leader top for Kelly rope Kelly Leader top for auxiliary rope Rotary Inclination device Casing driver Auxiliary winch Radius adjustment device Crowd winch Casing oscillator Kelly winch Undercarriage Counterweight 22,49 lbs The robust universal machine for a wide variety of applications: The solid undercarriage offers excellent stability and low ground bearing pressure. The uppercarriage with its small swing radius enables operation in restricted space. der. The rigid leader absorbs high torque and is fitted with a rope crowd system for high pull forces. All winches are mounted on the leader, which provides a direct view of the main winch from the operator s cab. The rotary drive of the BAT series combines exceptional torque with optimum operating comfort. The powerful Liebherr diesel engine is low in emission and economical through SCR technology. The Litronic control with assistance systems supports the operator: Sophisticated solutions provide safe operation and maintenance of the machine: Liebherr Kelly s feature strongly overlapping elements resulting in less wear. Precise and robust Liebherr casings and drilling tools provide excellent drilling performance. 2 LB 24-27 23.5

Technical description Engine Liebherr D 936 A7-4 Fuel tank 185 gal capacity with continuous level indicator and reserve warning Hydraulic system displacement pumps work in open circuits supplying oil only when needed (flow control on demand). The hydraulic pressure peaks are absorbed by the integrated automatic pressure compensation, which relieves the pump and saves fuel. Pumps for working tools 34 gal/min 159 gal The cleaning of the hydraulic oils occurs via an electronically monitored pressure and return filter. Any clogging is shown on the display in the cab. The use of synthetic environmentally friendly oil is also possible. Crawlers loaded multi disc brake, maintenance-free crawler tracks, hydraulic chain tensioning device.

Certain recordings, e.g. for a particular day or jobsite, can be found using filter functions. Viewing data - The data in each record is displayed tabularly. Combining several recordings provides results, available for quick analysis. Generating reports - A vital element of PDR is the report generator, which allows for the generation of thickness or even the desired logo can be configured.
