The LP 650/750 is a forward/reverse running, two-drum roller that is ideal for the compaction of earth
and asphalt compounds. The machine consists of a welded lower frame with a vibrator element located
between the two drums. Transmission to the vibrator element is made with the aid of hydraulic power
and propulsion is also hydraulic via chain drive to the drums. Infinitely regulated speed control
facilitates operation. The machine is equipped with a 56 litre (15 gallon) sprinkler system to permit long
shifts without the need of refilling. The water cock is well protected and easily accessible for the opera-
tor. The water tanks are made of plastic to avoid corrosion and the filler caps are large in order to
facilitate refilling. The lower part of the machine has a small overhang to allow the roller to be run
close to obstructions, eg, walls. The upper part is suspended by four rubber dampers and is secured to
the lower part with safety straps. The engine is fitted with a centrifugal clutch to relieve the hydraulic
system when idling. The machine is also equipped with a safety frame to protect the engine during
transport and work, and the frame is provided with a single-point hoisting bracket for easy loading and
unloading. The handlebar is retractable to facilitate transportation. The machine is equipped with a
dead-man’s handle. Electric starter, and push-stop to reduce the danger of crushing, are available as
optional accessories.
The machine and its accessories may only be used for their intended purpose. The LP rollers
are designed for operation in well ventilated spaces, as all combustion engine machines.
