Typifying the current boom in the loader crane market is Dutch manufacturer Hyva which extended its range of hydraulic loader cranes with three new models at the end of 2017. The new models are the HC951, HC1151 and HC1651, rated at 95, 115 and 165 tonne-metres, respectively. Typical applications are in the rental service sector for multi-purpose loading activities with specialist driver-operators, explained Davide Catellani, Hyva director, cranes. “They also meet the requirements for heavy equipment and materials lifting in the oil and gas, mining, logistics, defence and construction sectors,” Catellani continued.
All three new cranes have continuous slewing with two slewing motors, the Liftrod Articulating System (LAS) for constant capacity through the radius range and the Extra Extension Speed (EES) and Smart Extension Sequence functions for faster operating speed, shorter load cycle times, and more precise and safer operation, Hyva said.
Another feature of the design is an integral base that allows the crane to be mounted directly to the truck chassis, reducing height and lowering the centre of gravity. As an example, the HC1151 with eight hydraulic extensions has a reach of 19.52 metres. Included is an automatic lubrication system to simplify maintenance and help maximise resale value.
In Sweden, buoyed by the success of its ePTO electric plug-in-system and Moffett E-series electric truck-mounted forklifts, on-road load handling equipment provider Hiab has continued focusing on maximising the eco-efficiency of its loader cranes. At the end of 2017 it launched the cyclone oil tank which, it claims, reduces oil usage, weight, space and running costs. “The patented technology introduces a new generation of efficient hydraulic oil tanks,” says Joakim Andersson, Hiab senior vice president, loader cranes. “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 reduced. 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, we can now fit a 100 litre cyclone tank. This reduced size and weight allows the truck to reduce its fuel consumption and lower its carbon dioxide emissions by up to 600 kg a year. 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.”
