Features:
The Cat® CP56B features a padfoot drum and is ideally suited for cohesive
and semi-cohesive soil applications:
n Comfortable and ergonomic operator station features pivoting
seat with integrated multifunction LCD display and control console,
outstanding visibility to the front and rear of machine, low sound levels
and vibration for greater operator comfort and productivity.
n World-class propel system built around the exclusive Cat dual pump
propel system, two pumps provide separate dedicated flow to drum
drive motor and rear axle motor for exceptional gradeability and
traction in forward and reverse. New electronic propel control enables
more precise machine control.

Padfoot drum
Vibratory Soil ComPaCtor
n Virtually maintenance free due to maintenance-free hitch bearings
and extended maintenance intervals for vibratory system and hydraulic
system, providing more uptime and lower maintenance costs.

n Cat
Compaction Control - Machine Drive Power (MDP) Option helps
the operator determine when compaction has been completed to spec
for greater productivity and uniform compaction quality.
n Enhanced compaction performance due to more weight at the drum
and greater amplitude. Automated propel and vibratory system
functions make it easy to ensure consistent, high quality.
n Involuted Oval Padfoot Design provides deeper compaction than
square faced pad designs. Square pad design also available.
