Quick Couplers Couplers To maximize performance, Caterpillar Pin-Grabber Quick Couplers are compatible with all standard work tools, enabling the operator to simply release one work tool and pick up another, maximizing productivity. The couplers are available in hydraulic and manual versions. Auxiliary Hydraulics The combined function high-pressure auxiliary lines and quick connectors are fitted as standard.

This auxiliary system includes a diverter valve which provides optimum performance when using a one-way flow hammer or two-way flow auger and thumb work tool. This feature allows the machine to adapt to a wide variety of applications without re-configuring the auxiliary lines. Versatility is further enhanced with optional hydraulic lines enabling the use of a hydraulic quick coupler. A secondary auxiliary supply circuit for work tools utilizing a rotating or other medium-pressure circuit is also available as an optional attachment.

The stiff link thumb incorporates the use of a fixed link between the thumb and the stick, requiring bucket curl to secure the load. The hydraulic thumb replaces the stiff link with a cylinder that enables movement by both the thumb link and the bucket to grab an object. A progressive link thumb works much like a hydraulic thumb with more thumb rotation by incorporating an additional link.

This additional rotation provides a better working range when securing material. The three varieties come with two lengths, one compatible with a pin-on bucket and one compatible with a pin-grabber coupler.

Undercarriage Excellent stability. Rubber Pads Offered through the dealer parts system, the mm 18 in wide shoe has four holes that attach rubber pads to the track.

This option will prevent damage to paved road surfaces minimizing noise and vibration during travel with a standard steel track system. Steel Track The standard track offering is a mm 18 in triple grouser track.

Grease-lubricated track links, split master link and sealed track rollers reduce owning and operating costs. Steel tracks provide optimum stability when lifting over the side. This track is also offered in a mm 24 in width that provides additional stability and reduced ground pressure.

Rubber Belt New to the D-Series is a mm 18 in width rubber belt. This rubber belt is a traditional mini excavator attachment providing minimal work site damage and the ability to work on multiple surfaces. Construction of this rubber track consists of embedded steel shanks which engage the sprocket and steel cables ensuring rigidity and straight travel.

Segmented Rubber Track The mm 18 in wide segmented rubber track incorporates the best attributes of both the steel track and the rubber belt. Stability is maximized due to the rigid rubber pads that bolt to the track chain. The thick rubber pads are individually serviceable, minimizing work site damage and provide long wear life.

Blade Widths The dozer blade is an important tool used for backfilling trenches, levelling, landscaping, lifting and jobsite clean-up. There are two blade options available. The standard mm 91 in blade comes with a replaceable weld-on dozer wear edge and the optional mm 97 in blade comes with a replaceable bolt-on dozer wear edge.

Both blades are constructed of hardened steel for longer life and extreme dozing ability. Tie-down Points Tie-down points are located on the blade and undercarriage for easy and safe machine tie down for transportation.

Serviceability Easy access and minimal maintenance requirements keep your machine on the job. Full steel body work panels and protected front linkage lines are routed neatly out of the way of potential damage above the boom.

Easy access to all daily service points are accessed through the rear hood and side cover. Product Link The optional Product Link system simplifies equipment fleet tracking. Using satellite or cellular technology, the system automatically reports information such as location, machine hours, active and logged service codes and security alarms. MSS uses electronically coded keys selected by the customer to limit usage by individuals or time parameters.
