Building construction machinery and equipment - Safety
requirements of drill rigs
1 Scope
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.;
d) Casing or drilling fluid may be used to stabilize the drill hole.
Self-propelled drill rigs includes equipment with a movable chassis such as a
truck, tractor or other wheeled chassis, a tracked chassis, a walking chassis, a
sliding chassis (pulled by a winch), etc. Drill rigs using a truck, tractor, trailer
chassis or other wheeled chassis can travel at a higher speed on the road. Its
design and manufacture shall comply with the standards and regulations for both
drill rigs and road transport vehicles.
If the main machine of the drill rig is an excavator, crane, etc., this type of main
machine shall comply with its own standards when the requirements of this
Standard are not applicable.
If the drill rig is equipped with additional working devices other than the drilling
components specified in this Standard, such as piling devices, these additional
working devices shall also comply with their own safety standards.
Drill rigs used in explosive gas environments shall comply with the provisions
of relevant standards for equipment used in explosive gas environments.
This Standard does not apply to drill rigs used in the petroleum and natural gas industry,
or drill rigs used in open pit and underground mines.
2 Normative references
The terms in the following documents become the terms of this Standard by reference
to this Standard. For dated references, all subsequent amendments (not including errata
content) or revisions do not apply to this standard. However, parties to agreements that
are based on this Standard are encouraged to study whether the latest versions of these
documents can be used. For undated references, the latest edition applies to this
Standard.

The materials used in drill rigs shall not be harmful to the safety and health of exposed
person. The material shall be suitable for the intended ambient temperature. The
manufacturer shall indicate the designed operating temperature range of the drill rig in
the operating instruction manual.
5.1.7 Manual operation of drill rig and its components
The lifting points or lifting aids for the complete drill rig or parts shall be clearly
specified. The lifting points or lifting aids can also be used for fixation and protection
during transportation. The lifting points shall be clearly marked.
The articulated chassis shall have a mechanical locking device to lock the hinge point
during lifting and transportation. The locking device shall comply with GB/T 22355.
Drill rig parts that need to be operated by hand shall be designed to be safe for manual
operation.
If the weight and/or shape of a component prevents safe manual operation, it shall be
designed so that a lifting device can be used safely.
