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.

Single 32mm diameter corner pin connection for rapid assembly on site.
Excellent structural performance makes them ideal for higher load design applications in deeper excavations.
Double acting hydraulics enable the legs to be both expanded and retracted hydraulically by a suitable installation pump unit.
Integral hydraulic lock of valve enables the pump hoses to be easily released and reconnected without fluid loss.
690,900M and 900S legs have a rough adjustment facility for greater on site adjustment.

The range consist of 5 individual legs, each incorporating a hydraulically adjustable ram unit, which provides up to 1.0m of on-site fine length adjustment. In addition, three of the legs also have a rough adjuster unit providing further course length adjustment.

Leg Ref.	External Working Range		Leg Weight (kg)	Beam Width (mm)	Clear Opening (m)*
	Min	Max			Min	Max
290	1.5	2.25	175	200	1.1	1.85
490	2.24	3.24	250	200	1.84	2.84
690	2.9	4.6	440	220	2.452	4.152
900M	4.5	6.5	585	240	4.028	6.028
900S	6.3	8.3	650	240	5.868	7.868

* 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.

GF Double Acting Manhole Brace

The GF Double Acting Manhole Brace range consists of a series of hydraulically adjustable legs which, when assembled together, form a 4-sided telescopic hydraulic bracing frame which is used in conjunction with trench sheeting to support square or rectangular excavations from 2.0m up to 6.0m long.

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.

Hydraulic Pumps

Manual Shoring Pumps provide the means to hydraulically expand, pressurise and retract Groundforce hydraulically operated shoring equipment. Hand pumps are generally recommended for use with smaller equipment where the volume of fluid within the internal rams is relatively small. For larger bracing frames and struts, motorised pumps are recommended.

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.
