Legs are constructed from high yield steel sections and incorporate a double acting hydraulic ram. This means the legs can be both expanded and retracted hydraulically which aids the installation and removal process. In addition, some legs have a pinned rough adjustment which increases the operating range of the legs.

Leg Ref. External Working Range Leg Weight (kg) Beam Width (mm) Clear Opening (m)*
  Min Max     Min Max
A 2.0 3.0 260 180 1.64 2.64
B 3.0 4.0 305 180 2.64 3.64
C 4.0 5.0 390 180 3.64 4.64
D 5.0 6.0 445 180 4.64 5.64

* These ranges do not take into account the potential deflection of the waling beam, which will be dependent upon applied load and upon span. As such, the actual clear opening achieved is likely to be smaller than the values quoted above. 

These figures should be used as a rough guide and should not be relied upon to provide an accurate assessment of clear opening.

Mechshore Double Acting Series

Mechshore Double Acting Series

The Mechshore Double Acting Manhole Brace range consists of a series of non-modular hydraulically adjustable legs which are connected together to form a mid-range load capacity bracing system to support square or rectangular excavation sizes from 1.5m to 8.3m.

Larssen Sheet Piles

Larssen Sheet Piles

Larssen Piles are a type of sheet piling that has an interlocking section which forms a sheet piling retaining wall. Each sheet pile section is connected at 180 degrees from the previous one to form a uniform wall with alternating troughs and peaks. Larssen Sheet Piles are typically used in temporary or permanent cofferdams, retaining walls and foundation construction.

Trench Sheet (Standard)

Trench Sheet (Standard)

Groundforce Shorco offer a comprehensive range of cold formed lapped trench sheets and interlocking light pile sections to provide a cost effective solution for most excavation support applications. Many of the sections are produced from high yield steel which provides an exceptional strength-to-weight ratio resulting excellent durability whilst driving and resistance to on-site damage.

Maxi Brace

Maxi Brace

The Maxi Brace is a mid-range, heavy duty, hydraulically adjustable bracing system suitable for supporting clear span square or rectangular excavations ranging from 3m to 12m in size. Higher load capacity and/or longer spans can be achieved by incorporating either cross strutting of knee bracing. Modular extensions are available to further extend beam lengths, however cross strutting is required with these leg configurations.
