A low-loading hook-lift trailer that can “squat” to take on a multitude of bodies has been developed by Swedish manufacturer Ivarssons, for its Metsjo product range.

The 7.5m-long trailer, which can accommodate bodies of 5-6.5m, is based on the company’s long-established MetaFlex 50-65 model, but with hydraulic suspension.

When lowered to the full extent with a deck height of 95cm – up to 40cm lower than other hook-lift trailers, the company reckons – it makes it easier to haul interchangeable bodies aboard.

Axles are mounted apart, one at about the centre of the chassis, the second towards the rear (to distribute loaded weight and allow a higher payload), and the rear axle has castor steering to maintain manoeuvrability and low tyre scrub.

Both axles are carried on pivoting trailing arms, with double-acting hydraulic cylinders providing the “springs”, and with the air brake actuators mounted high up to give adequate clearance.

The deck can be adjusted through 35cm on these cylinders to load or off-load bodies at a reduced angle, before being raised to the regular running height.

Faster body changes and greater stability are two benefits of the trailer’s configuration, says the manufacturer.

The MetaFlex 50-65 Low, priced at around £46,000, is built from high-strength steel to keep its net weight down to 4.3t. The chassis unit’s carrying and body tipping capacity is rated at 22t.

In addition to several hook-lift chassis models, Ivarssons also builds Eucon hook-lift bodies with flap-type or hydraulic lifting tail doors for grain and other crops, and a grain chaser body with a high-capacity discharge auger.

Grass and maize silage bodies, heavy-duty earth/gravel bodies, and flat decks for transporting bales, potato boxes, machines and so on, are also produced.
