Reliable power
- Manufactured in some of the world's most modern and highly-automated production facilities, the Cat® C1.1 is proven to deliver durable power and offers a wide range of customization options that refuse to compromise quality and durablity.
Compact size
- With a 18.4 kW (24 hp) power rating, the C1.1 and the C1.1 turbo allows OEMs to consider different installation, operating and commercial requirements. These models are particularly adapted to machines where power from a smallpackage is crucial. And for jobs that require that extra bit of power, there's a turbocharged option that delivers in almost any condition, at any altitude.
Quiet work
- The stiff block and indirect injection system in the C1.1 were built for quiet so worksites are safer, operators are lessfatigued and noise levels in regulated areas aren't exceeded.
