Safer digging under pressure with trailer-mounted vacuum excavators
7 August 2015
Increasingly rigorous safety requirements and the adoption of mining specs in civil applications are driving customer demand for advanced equipment hire performance, especially on work sites with limited access or working area.
Coates Hire has met the need for safety-compliant non-destructive digging solutions that can be deployed in problem work sites by adding 29 new Vermeer VX250 trailer-mounted vacuum excavators to its national fleet.
“The process that the units use is a combination of jetting higher pressure water that creates a slurry in the ground that the vacuum then pulls out of the hole,” National Product Manager Mark Forbes says. “It reduces the risk of damaging in-ground services that can be cut by mechanical excavation.”
The VX250 excavation system is designed for work in the water, gas, fibre optic and construction markets, with a self-contained trailer-mounted 986 litre vacuum excavation system powered by a 30 horsepower diesel engine, a 575cfm blower with 381Hg of vacuum and a 3000psi water pump.
Forbes says that the units are extremely versatile, with applications ranging from potholing to emptying sump pits, with the ability to handle solids up to 60 to 70 millimetres in diameter, and can also be used for dry vacuuming.
“The fact that they are trailerised provides access to restricted locations and confined areas, compared to truck-mounted versions,” he points out.
He says the Vermeer units’ performance plus the add-ons that Coates Hire delivers tangible customer benefits.
“We’re always looking at and addressing customer markets – where they are working and need to take those units – to remove the limitations, and also from a safety perspective to provide the best OH&S solutions.”
