danger.
5.2 Basic Safety Requirements for Situations without Driver’s Cab
5.2.1 The control mechanisms shall have plates indicating their actions.
5.2.2 The operator’s operating position setting shall comply with ergonomic principles.
5.2.3 The control platform shall be set up in a location that is convenient for observation.
5.2.4 Under working conditions, when the ambient noise in the operator’s control area is greater
than 85 dB(A), a noise reduction device (earplugs or headset) shall be provided.
5.2.5 Under working conditions, when there are splashing objects in the control area or when
the dust concentration is excessively high, the operator shall wear a helmet and dust mask.
5.3 General Safety Requirements
5.3.1 All slewing and moving parts, except for the drill rod, propulsion mechanism and
traveling mechanism, shall be equipped with protective measures if they are dangerous to the
operator. Any dangerous areas or components, such as. transmission, high temperature, circuits
and fragile parts, that may be touched by the operator shall be isolated with protective devices
(such as. protective covers and protective plates, etc.). The design of the product protective
devices shall comply with the requirements of GB/T 8196.
5.3.2 The rated pressure of pipes, hoses and pipe joints shall be not less than the design pressure
of the system. The hoses shall be pressure-resistant, oil-resistant, wear-resistant and flexible,
and shall be free from damage and aging, etc. Short and complete hoses shall be used as much
as possible, and the hoses shall be marked with the allowable working pressure. Hoses or pipes
near the driver’s operating position shall be equipped with protective guards in accordance with
the requirements of JB/T 3249, so as to prevent the pipes or hoses from bursting and injuring
the operator.
5.3.3 The energy source of the drilling rig shall be independent, and each independent
component shall have a device for disconnecting from the energy source. This type of devices
shall be clearly marked. If re-connection may endanger those around them, they shall be able
to be locked. After the drilling rig cuts off the energy source, it shall be able to safely release
the energy left or stored in the circuit, so that there is no danger to people around it. Certain
circuits may remain connected to the energy source in order to clamp workpieces, store
information and provide internal lighting. Under this circumstance, special measures shall be
taken to protect the safety of the operator.
5.3.4 If there is a risk of contact with hot or cold surfaces, these surfaces shall be equipped with
guardrails or covers. The design of sharp edges, corners and protruding parts shall comply with
the requirements of GB/T 15706.2.
5.3.5 The design of the handle shall make it easy for the operator to control the entire machine,
and shall ensure that it does not cause injuries, for example, hand pinching, when used.
5.3.6 Various pipeline valves shall be properly sealed, flexibly opened, and shall not leak after
closing. Various pipe joints, including the air inlet (oil, water) joints and th...
