Track Asphalt Pavers(Non Current)

Caterpillar offers a broad range of Cat® asphalt pavers that compete in the rubber tire, steel track and rubber belted markets. High horsepower and excellent mobility help operators place the mat where they want it. All models are equipped with independent feeder systems designed to reduce segregation and handwork. The ventilation system draws fumes away from the conveyor tunnel as well as the auger chamber and redirects them away from the operator for a more comfortable working environment. Electronic self-diagnostics on the propel and feeder systems maximize maintenance efficiency and reduce machine downtime. Cat screeds feature hydraulic variable-width adjustment and electrically heated screed plates. They are available in rear-extender and front-extender models.

BB621E Asphalt Paver

With a single operator, the BB621E meets all requirements for small and medium sized jobsites. Easy, simplified driving - with controls which give precise, immediate response. The BB621E is a compact, extremely versatile paver finisher, ideal for small jobsites in urban centers. For sidewalks, cycle paths, playgrounds, trench back filling and all maintenance and repair work, where it shows its notable qualities and features. This paver is designed to operate in limited spaces, thanks to its compactness and exceptional maneuverability.

The machine’s tracked undercarriage, fitted with heavy-duty rubber bonded pads, provides excellent stability and weight distribution minimising the negative effect of an uneven base. Track tension is assured by two grease pistons with a shock absorbing system.

Cat C2.2 Engine

Reliable Cat C2.2 engine provides ample power and is EU Stage IIIb emissions compliant.

RB260 Electric Screed

The electric heated screed is powered by an onboard generator with independent temperature control in all four sections. Three heating elements for each screed section ensure uniform heating over the entire screed plate.

Material Feeding System

The hoppers are hydraulically operated and independently controlled facilitating applications close to walls or other vertical objects. The asphalt mix is carried to the screed by a heavy-duty steel conveyor and is distributed by two independently controlled augers, with reversible rotation. Three automatic material feed sensors provide correct amount of material to the screed. Augers can be hydraulically raised to avoid obstacles, facilitate machine loading on trailer and assembly of the paving width reduction option group. Conveyor and augers are reversible.

Operator's Platform

The operator drives the paver from the platform positioned behind the screed. The console panel is fully equipped with comprehensive controls allowing a single operator to conveniently monitor all machine functions. The operator platform is fitted with an operator presence detector enabling machine functions when the operator is in the driving position.


The BB621E ensures excellent access to all machine parts requiring scheduled maintenance. Large access doors provide quick and easy inspection of main components.
