We delivered a PK PRS400 four-axle trailer to Čistoća, a branch of Zagreb Holding. We designed and manufactured the trailer in-house at PK to transport machinery, commercial vehicles and accommodation containers.

The trailer has a permissible payload of up to 30 tonnes and a loading height of 900 mm. The loading deck is 2,540 mm wide and can be extended to approximately 3,000 mm. Manual twist locks secure 20-foot accommodation containers to the deck.

Two folding, two-section hydraulic ramps make it easier to load and unload machinery and vehicles. Each ramp is 4,100 mm long when fully extended. The ramps can be moved sideways hydraulically to adjust the spacing for different vehicle and machine widths.

The first and second axles turn with the drawbar, the third is a lift axle, and the fourth is a steering axle. The drawbar is adjustable in length and height and features a 40 mm towing eye for easy coupling to the towing vehicle.

An odometer is fitted to one of the axles, and the WABCO SmartBoard displays the trailer’s total weight. The chassis is hot-dip galvanised for corrosion protection and finished in orange.

Čistoća collects mixed municipal waste and biowaste in Zagreb and provides separate waste collection through bins, recycling centres and mobile recycling centres. It also cleans and washes public areas, including roads, pavements and squares.
