Manhole Ring Lifter

Manhole Ring Lifter

This universal mechanical attachment allows Manhole Rings and cones to be safely gripped internally for precise transportation and installation. Reducing the need for manual intervention, and keeping operatives clear of the slewing excavator, means the Manhole Ring Lifter introduces greater safety in handling operations by assigning much of the control to the excavator driver.

Manhole Box

Manhole Box

A manhole box is similar to a trench box in it's basic function, but they incorporate integral end return panels for extra ground support when placing pre-cast manhole rings, as an alternative to sheets and frames. There are five available sizes catering to common manhole ring sizes. They can be quickly assembled and installed without an operator needing to enter the unsupported excavation, supporting trenches up to 5.5m using the base module and various struts. Ideal for most ground conditions.

Single Acting Manhole Brace

Single Acting Manhole Brace

The Single Acting Manhole Brace range consists of a series of non-modular, (single piece) hydraulically adjustable legs which are connected together to support square or rectangular excavation sizes ranging from 1.15m to 3.0m.

Backhoe Manhole Box

Backhoe Manhole Box

The Backhoe Manhole Box is lightweight and ideal for installing pre-cast manhole rings and trench runs, without the need to alter the trench width. It has a typical base weight of 912kg, and is suitable for excavations up to 4.0m deep. It has a simple pinned strut arrangement, with a range of strut lengths available for non-square configurations and a 1.2m clearance under the bottom strut. End closure panels are available to support the open ends of the box, and handrails can be added for extra safety.Browse more of our Trench Boxes
