Drilling Rig LB 4-7 EN LB 3.5
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 1. t LB 4-7 The robust universal machine for a wide variety of applications: Kelly drilling Auger drilling Full displacement drilling Double rotary drilling The solid undercarriage offers excellent stability and low ground bearing pressure. The uppercarriage with its small swing radius enables operation in restricted space. Parallel kinematics with a large working area allow to fold the leader back. 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. LB 4-7 3.5
Long leader, foldable Counterweight x 6 t LB 4-7 with optional equipment The Litronic control with assistance systems supports the operator: Cruise Control for the drilling process Joystick control for all machine functions Automatic shake-off function for working tools Leader inclination memory etc. Liebherr Kelly s feature strongly overlapping elements resulting in less wear. Precise and robust Liebherr casings and drilling tools provide excellent drilling performance. Sophisticated solutions provide safe operation and maintenance of the machine: Cab design for optimum visibility Acoustic and optic warning Walkways on the uppercarriage Safety rails on top of the uppercarriage Rear and side view cameras etc. LB 4-7 3.5 3

Technical data Engine Power rating according to ISO 949, 3 kw (49 hp) at 17 rpm Engine type Liebherr D 936 A7-4 Fuel tank 7 l capacity with continuous level indicator and reserve warning Engine complies with 97/68 EC Stage IV and NRMM exhaust certification EPA/CARB Tier 4f. Swing Consists of triple-row roller bearing with external teeth and two swing drives, fixed axial piston hydraulic motor, hydraulically released multi disc holding brake, planetary gearbox and pinion. Selector for 3 speed ranges to increase swing precision. Swing speed from 3.4 rpm continuously variable. Hydraulic system The main pumps are operated by a distributor gearbox. Axial piston variable displacement pumps work in open circuits supplying oil only when needed (flow control on demand). Hydraulic pressure peaks are absorbed by the integrated automatic pressure compensation, which relieves the pumps and saves fuel. Pumps for working tools Separate pump for kinematics Hydraulic oil tank Max. working pressure x 7 l/min 13 l/min 6 l 35 A system of electronically monitored pressure and return filters cleans the hydraulic oil. Any clogging is displayed in the cabin. The use of synthetic environmentally friendly oil is also possible. Control The control system developed and manufactured by Liebherr is designed to withstand extreme temperatures and the many heavy duty construction tasks for which this machine has been designed. Complete machine operating data are displayed on a high resolution monitor screen. A GSM/GPRS telematics module allows for remote inquiry of machine data and operational conditions. To ensure clarity of the information on display, different levels of data are shown in enlarged lettering and symbols. Control and monitoring of the sensors are also handled by this high technology system. Error indications are automatically displayed on the monitor in clear text. The machine is equipped with proportional control for all movements, which can be carried out simultaneously. Two joysticks are required for operation. Pedal control can be changed to hand control.

At the same time the PDE is operated using this touchscreen. The operator can enter various details (e.g. jobsite name, pile number, etc.) and start and stop recordings. A recording of every start-stop cycle carried out in the PDE is established on a CompactFlash memory card. The PDE can be configured in a number of ways, e.g. for the connection of external sensors and/or for the generation of a simple protocol as graphic file. Process data reporting - PDR (additional equipment) Comprehensive data evaluation and generation of reports on a PC is possible using the software PDR. Recordings management - The recordings generated by the PDE system can be imported and managed in PDR. The data can be imported directly from the CompactFlash card or via the Liebherr telematics system LiDAT. Certain recordings, e.g. for a particular day or jobsite, can be found using filter functions.

Combining several recordings provides results, for example, regarding the total concrete consumption or the average depth. Furthermore, a diagram editor is available for quick analysis. Generating reports - A vital element of PDR is the report generator, which allows for the generation of individual reports. These can be printed out directly or stored as pdf files. In the process the size, colour, line thickness or even the desired logo can be configured. Moreover, the reports can be displayed in different languages, e.g. in English and in the national language. 18 LB 4-7 3.5
