Product Information
Overview
The Conquip 3.5m Trench Box is a simple to assemble, two sided trench lining
support system designed to be installed by an excavator using the ‘dig and push’
technique, or by simply carrying out the excavaon and then lowering each box
into place.
The Trench Box is normally selected for installing ulity pipes where ground
movement is not crical. The size of the system required depends on maximum
trench depth requirements and the size of pipe secons. Extensions available for
trench depths of up to 5.18 metres and widths of up to 4 metres.
Manufactured in the UK from quality Brish and EU steel.
Conquip also supply a full range of suitable liing and extracon chains, edge
protecon and trench access accessories.

Important Assembly Notes
• Top extension boxes are to be assembled in the same way but only two
struts should be ed. Extension boxes are secured to the base boxes
using connector brackets and pins.
• Keep hands clear of naked surfaces.
Assembly Instrucons
1. Before assembling Conquip base boxes and extension boxes, lay mber
bearers on the ground.
2. Aach a cered 4 leg chain sling to the liing points on one of the panels and
lower onto the mber bearers.
3. Insert the rocker assemblies into the panel brackets and secure with
40mm pins and R-clips.
4. Lower the pre-assembled struts onto the rocker assemblies securing the struts
to the panel brackets using pins and R-clips.
5. Connect the 4 remaining rocker assemblies to the struts using pins
and R-clips.
6. Connect the sling to the liing points of the panel facing downwards and li
into posion above the struts.
7. Lower the plate carefully, guiding the runners onto the four upright
strut assemblies.
Do not detach the chains unl the panel is secured to the strut assemblies.
8. Secure the struts to the panel with the remaining four pins and R-clips.
9. Connect the liing sling to the top liing points on the Trench Box and li the
box to the upright working posion
10. The box is assembled and ready to move into the trench.

Important Installaon Notes
• All personnel involved in installaon must wear relevant personal protecve
equipment.
• Never enter an unsupported excavaon.
• Stage 6 should be carried out when the top of the base is approximately 1m
above ground level.
• It is mandatory to use edge protecon when carrying out trench support.
Installaon Instrucons
1. Excavate the ground to
approximately 90cm or deeper,
as ground condions permit.
Ensuring the spoil is discharged
away from the edge of the trench.
2. Aach a cered 4 leg chain sling
of the correct volume and lower
the box into the Trench.
3. The excavator operator digs
progressively between the two
faces of the box panels.
4. The rocker assemblies allow
vercal and horizontal movement
when the force from the bucket
is applied. This ensures the box
panels are not damaged during
installaon.
5. Connue to perform the ‘dig and
push’ installaon technique unl
the box is at the required depth.
6. We recommend the base box
protrudes 1m above ground level
before adding an extension box to
act as a safety barrier.
7. To add an extension box, aach the connectors to each corner inside the base
box and secure with pins and R-clips.
8. Aach a cered 4 leg chain of the correct volume to the extension box and
lower it on top of the base box.
9. Aach using pins and R-clips. Only once the extension box is secured can the
liing chains be removed.

11. Aach Conquip Edge Protecon panels to the Trench Box.
12. Complete the nal ‘dig and push’ unl the top of the Trench Box is at ground
level. Ensure the force is applied to the edge of the box panels, not the Edge
Protecon panels.
13. Backll against the sides of the panels to secure the Trench Box.
14. Repeat this process unl the trench has been fully excavated.
Extracon Instrucons
1. Backll the excavaon around the
extension box.
2. Aach a cered liing chain to
one of the top liing points on the
extension box.
3. Slowly li the corner of the
extension box.
4. Repeat this process for each liing
point in turn unl the extension
box is 90cm above the ground.
5. Loosen the telescopic
clamps and remove the Edge
Protecon panels.
6. Backll the trench.
7. Reaach a cered liing chain to one of the top liing points on the
extension box.
8. Li the corner of the extension box. Repeat this process for each liing point
in turn unl the base box is 1m above ground level.
10. Use the ‘dig and push’ technique unl the desired depth is achieved.

9. Aach a suitably rated 4 leg chain sling to the top liing points on the
extension box.
10. Remove the R-clips and pins to disconnect the extension box from the
base box.
11. Slowly li and move the extension box away from the excavaon.
12. Wind loading can cause instability if boxes are le upright. Conquip
recommend connecng a liing sling to the top liing points of the extension
box and lowering it on its side.
13. Remove the R-clips, pins and the connectors from the base box.
14. Backll the trench and extract the base box using the same method.
15. Aach a suitably rated 4 leg chain sling to the top liing points on the base
box and move away from the excavaon.
16. Connect a liing sling to the top liing points of the base box and lower it on
its side to prevent wind loading.
17. Once all Trench Boxes have been successfully extracted, ll in the remainder of
the trench and remove all equipment from the area.
