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. Using a cered liing sling connected to the four corner liing points, li
the panel onto some bearers and using the pins provided connect the rocker
assembly to the panel. (Fig 1.1)
2. Place all four struts onto the rockers protruding from the panel facing
upwards and secure them using the pins and R-clips supplied. (Fig 1.2)
3. Then connect the four remaining rocker assemblies to the struts using the
40mm pins and R-clips supplied.
4. Connect the sling to the liing points of the panel facing downwards and li
it into posion above the struts.
5. Lower the plate carefully, guiding the runners onto the four upright
strut assemblies.
6. Secure the struts to the panel with the remaining four pins and R-clips.
(Fig 1.3)
7. Disconnect the liing sling connecon points from the two lower liing points
and li the box to the upright working posion.
8. Connect the two free legs of the liing sling to the upper liing points of the
other panel before liing the box into the trench.

Connecng Extensions Boxes
1. The base box and extension box are connected via a connector bracket.
2. The connector bracket will t within the panel soldier of the base box and is
secured using a 40mm pin and R-clip.
3. The extension box is then placed on top of the base box. The protruding
connector bracket must lock into the top of the panel soldier of the
extension box.
4. Once in place, insert a 40mm Ø pin through the panel soldier and connector
bracket. Secure with an R-clip.

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
200mm 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 1m or deeper, as ground condions
permit.
2. Ensure spoil is discharged away from the edge of the trench.
3. Aach a cered 4 leg chain sling of the correct volume and lower the box
into the excavaon.
4. Backll against the sides of the panels.
5. The excavator operator digs progressively between the two faces of the box
panels.
6. Then uses the back of the bucket to push down on the 4 corners of the box in
turn. This is known as the ‘dig and push’ technique.
7. Connue to perform the ‘dig and push’ installaon technique unl the box is
at the required depth.
8. Conquip recommend the base box protrudes 1m above ground level before
adding an extension box to act as a safety barrier.
9. To add an extension box, aach the connectors to each corner inside the
base box and secure with pins and R-clips.
10. 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.
11. To secure the Manhole Box, add Conquip Edge Protecon panels. Complete
the nal ‘dig and push’ unl the top of the Manhole Box is at ground level.
Ensure the force is applied to the edge of the box panels, not the Edge
Protecon panels.

Extracon
1. Backll the excavaon around the Manhole Box.
2. Aach a cered liing chain to one of the liing points of the End Panel and
slowly li to loosen the ground.
3. Repeat this process on the opposite liing point, then alternate between the
two unl the top panel is 90cm above ground level.
4. Aach a suitably rated 2 leg chain to the corner liing points of the End
Panel. Slowly li it away from the excavaon and lay on mber bearers.
5. Backll inside the Manhole Box.
6. Aach a cered liing chain to one of the top liing points on the extension
box.
7. Slowly li the corner of the extension box.
8. Repeat this process for each liing point in turn unl the extension box is
90cm above the ground.
9. Loosen the telescopic clamps and remove the Edge Protecon panels.
10. Backll the excavaon.
11. Reaach a cered liing chain to one of the top liing points on the
extension box.
12. Li the corner of the extension box. Repeat this process for each liing point
in turn unl the base box is 90cm above ground level.
12. Conquip recommend using End Panels to secure the excavaon and prevent
potenal cave-ins.
13. To assemble, lay on mber bearers and connect to each other using the
plates, bolts, and nuts.
14. Aach a suitably rated 2 leg chain to the top liing points of the End Panels
and li into place. Use the back of the excavator bucket to push the End
Panel down ground level.
15. Backll against the End Panel to secure the Manhole Box.

21. Aach a suitable 4 leg chain to the top liing points on the box. Li the base
box away from the excavaon.
22. Connect a liing sling to the top liing points of the base box and manoeuvre
onto its side to prevent wind loading.
