Information

2022 Caterpillar Mini Excavators 302.7D CR

OVERVIEW

302.7D CR Mini Hydraulic Excavator

Features may include:

Compact Radius
  • Configured without the additional counterweight the 302.7D CR is a true zero tail swing machine with the upper body staying within the width of the undercarriage during rotation. This enables the operator to work within confined areas and concentrate on the work being performed without having to worry about the back of the machine.
Transport Weight
  • The 302.7D CR is designed with a transport weight below 2.7 tonnes (6,000 lb) with cab fitted.
  • This allows lower trailer transportation costs using a standard passenger vehicle (subject to national restrictions).
Auxiliary Hydraulics as Standard Fit
  • Machine is ‘ready to work.’ Hammer and two way lines complete with quick disconnect fittings are standard. Connections are located close to the tool to reduce hose lengths and any potential damage.
  • Additional lines options are available to further increase machine versatility.
  • Stick and bucket cylinder hoses are protected by routing them through the boom.
100% Pilot Controls
  • Delivers excellent machine control and lifetime ‘as new’ performance eliminating the need for linkage and cable maintenance.
Automatic Swing Lock
  • Safe transportation of the machine is aided by the Cat automatic swing lock which locks the machines upper body in place when the control console is raised or the engine is stopped.
Thumb Ready Stick (North American Builds)
  • Machine is configured with brackets and relief valves for simple and cost effective mounting of a hydraulic thumb.
Dozer Float
  • Ground levelling and finishing applications are fast and easier with the dozer float function engaged making site clean-up much more efficient.
Cab Comfort
  • The Cat® 302.7D CR gives the operator a large comfortable space in which to work. The ergonomic control layout, travel pedals and adjustable wrist rests are engineered to minimize operator fatigue and increase productivity.
Simultaneous Operation
  • Both machine upper body swing and boom offset can be controlled simultaneously for faster machine positioning and object handling.
Adjustable Flow Control
  • Machines configured with proportional auxiliary hydraulics include adjustable hydraulic flow control for even greater tool control. Especially useful with tools such as angling buckets.
