Drilling and foundation equipment - Safety - Part 4: Foundation equipment EN 16228-4:2014+A1:2021

Publication date:   Apr 14, 2022

Scope

This European Standard, together with part 1, deals with all significant hazards for foundation equipment when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer associated with the whole life time of the machine (see Clause 4).
The requirements of this part are complementary to the common requirements formulated in EN 16228-1:2014+A1:2021.
This document does not repeat the requirements from EN 16228-1:2014+A1:2021 but adds or replaces the requirements for application for foundation equipment.
In this document the general term "foundation equipment" covers several different types of machines used for installation and/or extracting by drilling (machines with a rotary torque greater than 35 kNm), driving, vibrating, pushing, pulling or a combination of techniques, or any other way, of:
- longitudinal foundation elements;
- soil improvement by vibrating and soil mixing techniques;
- vertical drainage.
NOTE Some foundation equipment may have an additional rotary head with a torque less than 35 kNm for pre-drilling applications; this equipment is covered by this standard.
Machines with one or more of the following characteristics are not covered by this standard, but are covered by EN 16228-2:
- machines that have a main rotary head torque of less than 35 kNm;
- machines that have multi-directional drilling capability;
- machines for which adding and removing rods or digging and drilling tools etc. is usually required during the installation/extraction process.
Typically the process of foundation techniques involves the installation of longitudinal elements such as concrete piles, steel beams, tubes and sheet piles, injection elements as tubes and hoses and casings for cast in situ.
