Double Acting Manhole Brace

The Double Acting Manhole Brace is a four-sided hydraulic bracing system used with trench sheets or sheet piles to support light to medium excavations.

Available in two versions (V1 and V2) to suit varying project requirements, our range can span sheet to sheet dimensions from 1.4 metres to 7 metres – see specification tables and technical documents in the tabs below for details. On-site engineer support is available from our technical sales team and temporary works designs can be acquired by contacting our hire desk team.

Description

FEATURES

  • Legs
  • Adaptors
  • Pins
  • R-Clips

BENEFITS

  • Able to extend both ways, the legs can be positioned without precise pre-measurement,
    reducing setup time and labour during installation.
  • V1 can span from 2 metre to 7 metres. V2 can span from 1.4 metres to 6 metres.
  • Controlled expansion in both directions makes it easier to apply the exact pressure required against excavation walls, improving stability and reducing the risk of over/under-loading.
  • Consistent and adjustable pressure enhances excavation support, preventing the risk of wall collapse and providing a safe environment for personnel to work in.
  • Particularly effective in manholes, shafts, trenches and other tight areas where traditional
    support systems are rigid or difficult to install.
  • Maintains even pressure distribution across excavation walls, reducing the likelihood of
    misalignment or localised failure points.

Why would I choose a Double Acting Manhole Brace over other excavation support methods?

Double Acting Manhole Braces are preferred to alternative methods like timbering or single-acting hydraulic struts, due to their superior safety, more efficient installation and greater load capacity in deep excavations. They are quick to assemble, suitable for a variety of excavation shapes and sizes and feature hydraulic rams that can retract making them easier to remove than Single Acting Manhole Braces.

What sizes of excavation can they span?

Conquip offer two variations of Double Acting Manhole Brace that can span excavations from 1.4 metres to 7 metres, sheet to sheet.

Are Double Acting Manhole Braces suitable for varying site conditions and ground pressures?

Yes they are. A Double Acting Manhole Brace can be precisely adjusted as they are installed and removed and they also offer high resistance after installation is complete.
