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.

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
