Rig should always check the item 1, the end of the steel cord to conduct inspections of consolidation; the contents of the wire rope inspection is: number of turns of wire rope safety, Shandong Engineering rig, wire selection, installation, lubrication, wire rope defect inspection, such as wire rope diameter and wear, broken wire number; 2, ready to rig a pulley system checks, the main test items are: a pulley body condition, transition pulley anti-skipping devices; 3, ready to rig running systems checks, mainly check project: pile driver walking tubes, pallets and hook pipe system status, laying sleepers rotary drilling rig is how it works, what works? Currently rotary drilling rig works the drill pipe in the form of multi-use connection bucket dig and dig slag slag during drilling mud circulation mode to use more mud lubricant for such rigs, support, replacement and carry the role of drill slag. With the urban construction and environmental protection requirements become more stringent, the traditional rig face greater crisis. The rotary drilling rig power head form, works with the rig use, while rotary drilling rig working principle is to use a short screw drill or auger bucket, using the powerful torque directly to the soil or gravel mining and other rotary drilling residue, and then quickly make holes outside , without the need to support the mud dry construction can be achieved, even in the case of special needs Slurry Wall formations, engineering rig, mud only play supporting role in the drilling mud content is very low, which makes pollution greatly reduced, thereby reducing the construction cost, but also improve the construction environment, high efficiency into the hole. This is the rotary drilling rig with good environmental properties. Engineering drilling rig manufacturers | engineering rigs | Long industry machinery supplied by Shandong Machinery Co., Ltd.
