Overview

Efficient and Consistent Compaction

The Cat® CS20 Vibratory Soil Compactor features a smooth drum and is ideally suited for granular soil applications or cohesive soil applications with the use of an optional padfoot shell kit. A reliable propel system improves performance and efficiency and compaction technology solutions help you reach target density faster.

Benefits

Low Operating Costs

Eco-Mode, no-maintenance hitch with sealed-for-life bearings and extended service intervals help keep your operating and maintenance costs low.

Increase Efficiency with Compaction Technology

On-board compaction measurement technology indicates when specifications are met helping to eliminate guesswork, reduce unnecessary passes and minimize rework.

Exceptional Visibility and Comfort

A rear vision camera enhances visibility around the machine and a pivoting seat with integrated controls and tiltable steering console provide an ergonomic work environment.

Features At A Glance

Efficient Power

Built around a dual pump propel system, two pumps provide separate dedicated flow to the drum drive motor and rear axle motor for exceptional gradeability and traction in forward and reverse.
Powered by a Cat® C7.1 engine that meets Brazil MAR-1, equivalent to U.S. EPA Tier 3 and EU Stage IIIA emission standards.
Eco-mode limits engine RPM helping to reduce fuel consumption.
Engine Idle Shutdown Timer reduces fuel burn and unnecessary idle time by shutting down the machine after a pre-set idling period.
A variable speed cooling fan operates at the lowest possible speed for optimal cooling.

Exceptional Compaction Performance

High static linear loads and amplitudes.
Exclusive eccentric weight design provides high reliability, smooth performance and low noise.
Automatic Speed Control and Auto-vibe functions make it easy to ensure consistent, high-quality compaction.
The Variable Frequency option provides a wide range of frequencies to help maximize compaction performance.
Increase machine versatility with the addition of an oval or square padfoot shell kit, allowing your smooth drum machine to compact semi-cohesive and cohesive materials.

Safe and Comfortable Work Environment

A rear vision camera with large color touchscreen display enhances visibility for more complete operator control and safety.
The pivoting seat with integrated multifunction LCD display and control console move with the operator.
Outstanding visibility to the front and rear of machine.
Low sound levels and vibration for greater operator comfort and productivity.
Operators are protected from the elements by a standard equipped sun canopy or optional climate-controlled ROPS/FOPS cab with hinged glass windows.

Enhance Quality and Productivity with Technology

Optional Cat Compact technologies help you consistently meet compaction targets faster, more uniformly, and in fewer passes – saving on fuel and reducing rework and material costs.
Exclusive Machine Drive Power (MDP) is an energy-based measurement and can be used on all soil types.
Compaction Meter Value (CMV) is an accelerometer-based measurement for granular soils.

Virtually Maintenance Free

Maintenance-free hitch with sealed-for-life bearings.
Ground-level access to the engine compartment and cooling module for easy service and fluid sampling.
Monitor fluid conditions with regular sampling to help extend change intervals up to 500 hours engine oil, 3000 hours eccentric housing and hydraulic oil, and 12000 hours coolant.
Extended maintenance intervals not only reduce downtime but decrease the amount of fluid and filters that are replaced over the life of the machine.
VisionLink® takes the guesswork out of managing your entire fleet–regardless of size or equipment manufacturer*–by providing maintenance needs, machine hours, location, fuel usage, idle time, diagnostic codes, and more through interactive dashboards on your mobile device or desktop, helping you make informed decisions that lower costs, simplify maintenance, and improve safety and security on your jobsite.

* Data field availability can vary by equipment manufacturer and is provided through an application programming interface (API).

The Cat C7.1 meets Brazil MAR-1 emission standards, equivalent to U.S. EPA Tier 3 and EU Stage IIIA.
Cat engines are compatible with diesel fuel blended with the following lower-carbon intensity fuels* up to: 20% biodiesel FAME (fatty acid methyl ester) and 100% renewable diesel, HVO (hydrotreated vegetable oil) and GTL (gas-to-liquid) fuels. Please consult your Cat dealer or "Caterpillar Machine Fluids Recommendations" (SEBU6250) for details.
*Tailpipe greenhouse gas emissions from lower-carbon intensity fuels are essentially the same as traditional fuels.
A well-trained operator is worth the investment. Skilled operators benefit your bottom line by maximizing productivity, avoiding costly downtime, and maintaining jobsite safety - which can help to improve fuel efficiency and reduce greenhouse gas emissions.
Extended maintenance intervals not only reduce downtime but can decrease the amount of fluid and filters that are replaced over the life of the machine. Extend change intervals up to 500 hours engine oil, 3000 hours eccentric housing and hydraulic oil, and 12000 hours coolant.
Performance and safety can be augmented with standard and optional cameras that are viewed on in-cab displays.
Cat Compact technologies help you consistently meet compaction targets faster, more uniformly, and in fewer passes - saving on fuel and reducing rework and material costs.
Cat Scheduled Oil Sampling (S•O•S℠) Services helps reveal excessive wear, contaminated fluids or other "unseen" issues that can shorten component life. In many cases, you can extend oil and coolant change intervals by using fluid monitoring. Consult your Cat dealer or the machine's operation and maintenance manual for more information.
