This Standard specifies the safety requirements for the design, manufacture, use and maintenance of drill rigs, mainly involving the important operational safety and ergonomics of drill rigs. This Standard applies to drill rigs, including casing, for surface and underground hole formation in building, tunnels, railways, roads, hydropower stations and water conservancy projects. Note: This Standard includes the major hazards of drill rigs under the conditions of intended use and foreseeable by the manufacturer. However, this Standard does not include all mechanical, electrical, hydraulic, pneumatic and other device hazards, nor does it include all hazards involved in general standards. Hazards not included in this Standard shall be subject to the relevant provisions of GB/T 15706.1 and GB/T 15706.2. The drill rigs to which this Standard applies mainly has the following characteristics: a) There are three types of drilling methods: impact, rotary and rotary impact; b) Chassis types include fixed, towed and self-propelled; c) Mainly used to form pile holes, anchor holes, blasting holes and drainage holes, etc. Specifically including the following models: ● Drill rigs for pile formation, mainly including impact drill rigs, rotary drill rigs, long spiral drill rigs, forward/reverse circulation drill rigs, swing/rotary casing drill rigs, pile top drill rigs, down-the-hole hammer rock drill rigs, etc.; ● Drill rigs for anchoring, mainly rotary and rotary impact drill rigs; ● Drill rigs for blasting holes, mainly including rock drills (cars), down-the-hole drills, rotary drills, etc.; ● Drill rigs for other purposes, including rotary spindle drill rigs, rotary and rotary impact drill rigs for surface/underground drilling, forward/reverse circulation drill rigs, horizontal directional drill rigs, etc.; GB 26545-2011 www.ChineseStandard.net  Buy True-PDF  Auto-delivery.
