Hiab launches Cyclone oil tank

8 January 2018 by Sotiris Kanaris


Hiab, part of Cargotec, has launched a new oil tank for its loader crane and forestry crane models which uses cyclone technology.

The manufacturer said this technology is the first of its kind in the industry and introduces a new generation of hydraulic oil tanks.

The tank uses a cyclone system to remove air from the hydraulic oil returning to the tank, which is up to ten times more efficient than standard systems. The technology allows oil to be circulated and filtered more often, so that the size of the tank can be significantly reduced.

“This means that the volume of oil required is also significantly reduced, plus the slight over-pressure in the system's outlet prevents cavitation in the oil pump, leading to a longer operational lifetime for the pump, oil and hydraulic system,” said Hiab.

Markus Sjöqvist, Hiab's product manager, loader crane accessories, added: “Because the cyclone removes air from the oil up to ten times more efficiently, we can work with a much more compact oil tank. So, for example, instead of the 250 or 300 liter 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.

“The tank size and weight reduction also gives additional cargo capacity, plus the advantages of lower oil usage of up to 60%, and a more durable hydraulic system, so operating costs are reduced too."

The cyclone tank technology works with most Hiab crane models. It can also be mounted directly onto the crane, and will be included in the crane's warranty package. The higher mounting position on the crane enables better operating conditions for the pump, and installation costs are lower than the truck-mounted option.
