Introduction
Assemble
Health and safety legislation states that construction equipment users should formulate a
site specific Safe System of Work to undertake any work they are planning. This brochure was
designed to oer basic instruction of Shoring Equipment Systems including the assembly,
installation and extraction of the Drag Box. The correct sizes and weights of the components will
also be shown so that use of equipment can be planned ahead. It is necessary that users enforce
the appropriate safety practices of excavations and trenching throughout installation.
The users of Shoring Equipment should be familiar, confident and competent when handling
and installing boxes and accessories. Altrad Generation Hire and Sale excavation systems can be
supplied with a full range of additional safety products including ladder access and guardrails as
well as various other ancillary products. These products are designed to act in accordance with
the practice of Shoring Equipment and meet the requirements of the Lifting Operations & Lifting
Equipment Regulations, Work at Height Regulations and the Confined Spaces Regulations.
Personnel should make themselves aware that certain conditions such as the close proximity
of structures, site roads, railways and excavated materials near the trench can all increase
surrounding earth pressures. If in doubt please seek advice.
For additional details please contact your local Altrad Generation Hire and Sale branch.

Safety Tips
•Please refrain from using the box on unstable ground and within close proximity to structures
due to increase in Earth Pressure.
•Plan all excavations ahead of time to ensure that the correct lifting operations can be used.
•Ensure that all personnel required to install this equipment are suitably trained and supervised
whilst assembly and installation is in progress.
• Inspect all components, including lifting points, struts, clips and pins.
• Boxes should never be left ying above the base of the excavation.
•Leave 100mm of the box above ground level on the base/top box.
•Refrain from bearing weight with the bucket in the middle of the panel during installation.
•Only access the box via ladder access.
•Never move the box whilst personnel are inside the excavation.
•Do not use any un-supported part of the trench as access.
•Top Boxes and extension panels are not to be removed before the top of the base box is above
ground level.
•To minimise damage do not lift the box via the struts or laterally load them.
