Crane company Hiab has released a new-generation hydraulic oil tank designed to reduce oil usage, weight, space and running costs.

The tank uses a cyclone system to remove air from the returning hydraulic oil – a process which Hiab says is up to 10 times more efficient than standard systems.
The on-road load handling company says this technology allows oil to be circulated and filtered more often, so that the size of the tank can be significantly reduced. This, in turn, reduces the volume of oil required.
In addition, the slight over-pressure in the system’s outlet prevents cavitation in the oil pump, which should lead to a longer operational lifetime for the pump, oil and hydraulic system.

“Our new cyclone oil tank is a game-changing accessory for use in a truck-mounted or crane-mounted application,” Hiab loader crane accessories product manager Markus Sjöqvist says.
“Because the cyclone removes air from the oil up to 10 times more efficiently, we can work with a much more compact oil tank. So, for example, instead of the 250 or 300-litre oil tank you would expect to find on a standard truck mounted with a loader crane or forestry crane, we can now fit a 100-liter cyclone tank.
“This reduced size and weight allows the truck to reduce its fuel consumption, and lower its CO2 emissions by up to 600kg a year,” he says.
“The tank size and weight reduction also gives additional cargo capacity, plus the advantages of lower oil usage of up to 60 per cent, and a more durable hydraulic system, so operating costs are reduced too.”
Hiab, which is part of Cargotec, says the new tank can also be mounted directly onto the crane and will be included in the crane’s warranty package.
