適用範囲

This standard specifies safety requirements for piling equipment used for foundations, continuous walls, or foundation support structures, as well as pile extraction and drainage pile construction. It covers equipment using piles made of wood, concrete, or steel. This standard is mandatory for all manufacturers and suppliers of piling equipment in China. It applies to piling rigs, pile installation and extracting equipment, and accessories. It also covers continuous wall construction equipment (see Appendix C). If the carrier machine is an excavator or crane, it must also comply with its own standards.

技術要求

The standard outlines comprehensive safety requirements across several categories. It mandates stability verification through calculations considering the stability angle and stabilizing moment. Manufacturers must verify stability before delivery and specify safe operating conditions in the manual. Requirements for ergonomics, protection from hot/cold surfaces, and hydraulic/pneumatic systems are specified in accordance with GB/T 3766 and GB/T 15706. It details strict criteria for pulleys, drums, and wire ropes, including minimum diameter ratios and safety factors depending on the working condition (e.g., general lifting, free fall hammer). Wire rope safety factors must not be less than the specified values in Table 1. Winches must have working and parking brake systems, and free-fall operations require dual independent controls. The standard also covers operator cabin safety, requiring protection against noise, dust, and weather, including FOPS (Falling Object Protective Structures) compliant with GB/T 17771. Fire prevention measures mandate portable fire extinguishers based on the equipment's rated power. Emergency stop devices must be easily accessible and comply with GB 16754.

試験方法

Verification of safety requirements must be conducted through calculation, inspection, and possible testing before delivery to the user. Manufacturers must provide identification documents and test reports for all emergency stop and safety stop functions. All lifting and lowering systems must be tested under their rated load. Stability, braking, noise, and vibration must be confirmed even if verification items are not explicitly detailed. Noise measurement in the operator cabin must follow GB/T 16710.3, and vibration assessment must comply with GB/T 13441.1.
