  Cabin     High standard cabin,safe,comfortable,healthy&environmental Safety performance I. Cabin adopt high-strength steel impact molding,protective screening cover the top and the window II. Stalinite window,the door’s open angle is 180°,with Full open positioning system,the lock could be opened up or down on the equipment. III.  360° field of vision in all directions,with suspension aero seat,meanwhile the control element’s layout is rational,easy to control;world top air conditioner ;full-sealed cabin, low noise,low pollution invasion,make the driver more comfortable. Hydraulic system for LG922 drilling rig I. Rotary drive motor,main/auxiliary winch motor adopt originally germany production,stable working performance II. world top brand Rexroth  Rotary drive motor,main/auxiliary winch motor&gearbox are adopt Rexroth, originally imported from germany,which is reliable;world top brand Bosch Rexroth LUDV Hydraulic control system,which significantly reduce energy consumption III. Electric Hydraulic Proporting Control&pilot control make sure the flexible and the safety of the whole system. IV.Main winch with remarkable pull force,also equipment with ‘touchdown protector’ and winch rope ‘antiwind’ function.

      Rotary Drive Adopt Roxroth double motor drive,more powerful Jib lubbing mechanism 1. adopt rhomboid adjust mechanism,and triangle uniform loading structure, to make sure the accurate of the drilling rig,meanwhile,it will not affect the perpendicularity. 2. adjust mast's working range and the hight of the machine during transport Mast 1. adopt box structure,make sure the anti-twist&resistant to bending abilitys 2. the whole mast is able to fold,easy to transport main winch 1. adopt original germany roxroth motor&gearbox,stable working performance 2. holding rope implement for coiling roller can avid wirerope's overlap,slip-away ,extrusion,wearout and listed them in good order,   Friction or locking-type drill pipe optionable 1. Friction drill pipe: Advantage:easy to operate,high drilling depth;during the lifting up time of the drill pipe,there will be no Inside and outside layer of the drill pipe to take off the lock,high efficiency Disadvantage:low pressure,not suitable to drilling into the hard stratum 2. Locking-type drill pipe High anti-twisted abilities,no pressure loss when passing the pressure to the drilling rig,suitable to drilling into the hard straum  Soil drilling bucket,Saturated sand drilling bucket,Spiral drilling bucket are optionable 1.  Soil drilling bucket.applicable to sludge,clay,Weathered soft rock ETC. The structure is not easy to loose,low strength stratum 2. Saturated sand drilling bucket.applicable to incompact soil,sandy soil with high water content ETC. looseness of structure,low strength stratum 3. Spiral drilling bucket.hard solum,sand gravel stratum,weathered rock formation Hard permafrost ETC. high strength stratum.
