Foreword
This document (EN 14653-2:2005) has been prepared by Technical Committee CEN/TC 53
“Temporary works equipment”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by October 2005, and conflicting national standards
shall be withdrawn at the latest by October 2005.
This European Standard with the general title Manually operated hydraulic shoring systems for
groundwork support consists of the following parts:
Part 1: Product specifications
Part 2: Assessment by calculation or test
These standards are to be read in conjunction with EN 12811-2 and EN 12811-3.
This document includes a Bibliography.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech
Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy,
Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia,
Spain, Sweden, Switzerland and United Kingdom.
Introduction
Manually operated hydraulic shoring systems comprise prefabricated equipment to support sheeting
to the sides of excavations. This document covers two types of equipment whose adjustment is by
hydraulic or a combination of hydraulic and mechanical means:
a) hydraulic bracing frames;
b) hydraulic waler frames.
A variety of components exist which when assembled forms a full system. The instruction manual
provides all the necessary information in the safe use of the systems.
The prefabricated components are used to make frame assemblies of different dimensions and
structural capacities.
This equipment is frequently used in conjunction with supplementary equipment, e.g. knee braces and
intermediate hydraulic bracing struts.
1 Scope
This document specifies methods of calculation and test to assess the conformity of manually
operated hydraulic systems for groundwork support whose performance is specified in EN 14653-1.

5 Requirements
5.1 General
All manually operated hydraulic shoring systems and components and their associated instruction
manuals shall be assessed to ensure conformity to all of the requirements of EN 14653-1.
5.2 Structural configurations to be assessed
Manually operated hydraulic shoring systems and components shall be assessed under the structural
configurations, that will induce the most severe loading effects specified by the manufacturer.
5.3 Loading configurations to be considered
Manually operated hydraulic shoring systems shall be assessed all under the loading configurations
specified in EN 14653-1:2005, 7.4.
5.4 Testing or calculation
5.4.1 Assessment shall be carried out by calculation in accordance with ENV 1993-1-1
(Eurocode 3) for steel or ENV 1999-1-1 (Eurocode 9) for aluminium. For cast iron ENV 1993-1-1 shall
be used, subject to 6.2 of EN 14653-1:2005. When appropriate calculation models are not available,
structural testing shall be undertaken.
5.4.2 Assessment shall be carried out by structural testing for the following circumstances:
a) when a calculation model is not available to represent a particular structural component or
assembly;
b) when there is a degree of uncertainty in the validity of the model chosen;
c) when verification of structural performances is required by EN 14653-1.
The following shall be assessed by structural testing:
1) the axial compressive resistance of hydraulic waler struts with spigot type extension bars as
defined in EN 14653-1:2005, 3.13.1 c).
2) the axial compressive resistance of rams and struts with restraints conditions not conforming
to those described in EN 14653-1:2005, 8.5.
3) mechanical locking mechanisms on waler struts as defined in EN 14653-1:2005, 3.12.1.
4)  Non-proprietary valves as defined in EN 14653-1:2005, 8.8.
6 Assessment by calculation
The internal forces and moments shall be calculated using elastic analysis methods. No plastic
redistribution of moments and forces are permitted.
The influence of the deflections on the internal forces and moments shall be determined either by
using second orde
