BL-800鉆機(jī)為全拖懸掛式，整體運(yùn)輸方便。 機(jī)械傳動，轉(zhuǎn)盤回轉(zhuǎn)，傳動平穩(wěn)；鉆機(jī)采用雙卷揚(yáng)結(jié)構(gòu)，塔頭平移可使副卷揚(yáng)中心自動對中，接卸鉆桿方便快捷。鉆塔整體液壓起降，鉆機(jī)整體液壓支腿調(diào)平，孔口板液壓開合，省力便捷；增加機(jī)械副支腿使鉆機(jī)更加安全、穩(wěn)固。鉆機(jī)最低轉(zhuǎn)速可至21r/min，適合空氣潛孔錘鉆進(jìn)。
主要用于工農(nóng)業(yè)水井鉆鑿、水文地質(zhì)勘查和橋樁工程孔等。
BL-800 drilling rig is trailer-type drilling rig and eady to transport.it is mechanical transmission and its rotary table rotate back and teansmit eery smooth.This rig adopts double winch structure and its tower head translation can make the auxuliary winch alignment automatically to the center.it is concenient to install and uninstall the drill rod The whole derrick is hydraulic landing, the whole rig hydraulic support leg adjust level and the plate is hydraulic open and close which is convenient： It also add equipment more safe and stable. The minimum revolution speed of this drilling machine can bo up to 21r/min and it is suitable for air DTH hammer drilling. Mainly used in industrial and agricultural water well drilling, hydrological geological exploration and pile construction.
