Heavy duty and economy from Palfinger
By Alex Dahm08 November 2011
Easy maintenance and cost effectiveness are primary features of a pair of new heavy duty knuckle boom loader cranes, according to manufacturer Palfinger.
The PK 44502 and the PK 48002 EH High Performance are designed to be cheap to run with minimal environmental impact. A highlight of the PK 48002 EH is its fly jib. Three versions are available initially. In addition to the PJ080 and PJ125 fly jib models is the new PJ100.
Larger of the two is the 46.5 tonne-metre PK 48002 EH and the PK 44502 is rated at 41.9 tonne-metres. They can have up to six hydraulic extensions giving both cranes an hydraulic outreach of 16.3 metres.
The EH version has HPLS where extra capacity is available at a lower working speed. Several crane functions can be performed at once thanks to electronic regulation of the main valve block. Powerlink is fitted as a mechanical means of smoothing out power delivery through the working range. Its reverse linkage allows the boom to be angled upwards by 15 degrees, for example, to improve access in confined spaces.
Another feature is the maintenance-free extension boom system. "The expenditure for servicing is considerably less due to the maintenance-free extension boom system. This is because the use of sliding elements made from special synthetic material combined with time-tested KTL cathodic dip painting means that the operator no longer needs to service the boom system," the manufacturer said.
