Foreword
This document (EN 14653-1:2005) 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shall be withdrawn at the latest by October 2005.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 hydraulically 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
Hydraulically operated shoring systems comprise prefabricated equipment that supports sheeting to
the sides of excavations. This document covers two types of equipment whose adjustment in length is
by hydraulic or by a combination of hydraulic and mechanical means:
a) hydraulic bracing frames;
b) hydraulic waler frames.
A variety of components which when assembled form a full system. The prefabricated components
are used to make frame assemblies of different dimensions and structural capacities.
Hydraulic bracing frames and waler frames have two strength classification classes - Class A and
Class B.
Class B hydraulic bracing frame legs have a further restriction limiting the length of a single leg to
20 m.
The instruction manual is intended to provide all the necessary information on the safe use of the
systems.
This document gives specific requirements on the main characteristics of manually operated hydraulic
pumps, hoses and associated equipment, but does not provide requirements for their specification or
assessment in EN 14653-2.
This equipment is frequently used in conjunction with supplementary equipment, e.g. knee braces and
intermediate hydraulic bracing struts.
The characteristic resistance values specified in this document form various reference levels.
Annex A gives information about the values of Partial safety factor for materials γ and Partial safety
M
factor for actions γ . Annex B gives information on their use under site conditions.

1 Scope
This document specifies constructional and structural requirements for manually operated hydraulic
shoring systems made from steel and aluminium for groundwork support.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
rams
3.1.1
hydraulic ram
adjustable component that withstands force and whose length can be varied by the application of
hydraulic pressure (see Figure 1, Figure 2 and Figure 3)
NOTE 1 A separate manually operated pump activates the ram.
NOTE 2 The term ‘ram’ has been adopted to distinguish the component from the more general term ‘cylinder’.
Rams only receive static loading from ground pressure and do not require specific duty cycles or cycle rates.
3.1.2
single acting ram (SA)
hydraulic ram that under hydraulic pressure only extends and cannot retract hydraulically
NOTE 1 A single acting ram can only support compressive forces.
NOTE 2 There are three types of single acting ram available a, b and c (see Figures 1 and 2).
a) Displacement type (D) see Figure 1 a);
b) Piston type (P) see Figure 1 b);
c) Multi-stage rams; these rams may be piston types, displacement types or a combination of both (M).
NOTE 3 A single acting ram may be supplied with a mechanical spring return (SR), which provides a double-
acting action without the requirement for a hydraulic return. The spring takes effect when the hydraulic pressure
is released, (see Figure 2).
