Cabs with the door option installed feature an automatic lock-out switch that prevents accidental damage by disabling the loader functions when the door is open.
High-Efficiency Climate Controls
Operating in extreme temperatures can be more comfortable with the optional cab air conditioner and heater installed. Airflow is directed through six adjustable vents. Vents make defrosting the optional front door and side windows easy. The heater and air conditioner can be ordered separately or together.
Cat Skid Steer Loader instrument panels and gauges are simple, easy to use and reliable. Bright indicator lights and audible warnings signal any critical system situation. Positive feel switches, with status lights, control most on/off functions. An engine air cleaner restriction indicator is now in the cab for easier monitoring.
Operating ease and productivity are enhanced on the Cat Skid Steer Loader with excellent visibility. The wide cab opening offers an exceptional view of the work tool. The sloped angle of the engine compartment allows excellent visibility to the rear of the machine. A standard convex rearview mirror gives the operator a panoramic view of the machine's rear and sides. For better visibility in low-light conditions, the standard forward lights are adjustable 10 degrees in any direction.
The Cat Skid Steer Loader cab is designed to make machine operation simple, productive and comfortable. Getting in and out of the cab is easy through a wide opening with three point grab irons and skid-resistant steps. Tilt cylinders are neatly located under the lift arms so not to interfere with operator access and egress. Plenty of uncluttered floor space makes stepping into the cab even easier.
Several cab packages and options are available. The standard cab offers features such as an adjustable contoured seat, cushioned armbar, dual throttle controls, pilot operated joysticks, 12 volt DC power socket and optional cup holder.
High Performance Power Train
Caterpillar hystat power train delivers aggressive performance and easy operation.
Cat Diesel Power
The heart of the Cat Skid Steer Loader power train is the Caterpillar C3.4 DIT diesel engine. This rugged, reliable, four cylinder engine offers aggressive performance and a fast torque curve for quick response. It is also a low emission engine and is Interim Tier 4 compliant.
Dual Engine Throttle Controls
The hand and foot throttles allow the operator to match engine speed to the task. The hand throttle is ideal for jobs requiring consistent engine speed - such as cold planing, trenching or snow blowing. The foot throttle lets the operator vary engine speed and minimize fuel consumption for other tasks such as load and carry, truck loading, grading and dozing.
The anti-stall system on the Cat Skid Steer Loader allows maximum power to the wheels while minimizing engine stalling. This system helps maximize productivity for experienced operators and makes it easier for novice operators to become productive.
Variable-Displacement Piston Pumps
The dual, variable-displacement, axial piston pumps are driven directly off the engine and provide hydraulic flow to the drive motors via a closed loop system. Drive motors transfer mechanical power to the wheels via two high-strength, pre-stressed chains per machine side. Chains run in an oil bath for constant lubrication and long life. Chains are adjustable through slots in the axle housings.
The drive axles are forged and induction hardened for maximum life. They include a unique lip and outer seal to help prevent debris such as wire and twine from wrapping around the axle and destroying the seal. An inner seal is used for permanent lubrication of axle bearings so no daily axle service is required.
Advanced Hydraulic System
Hydraulic system has built-in reliability and provides exceptional lift, breakout and auxiliary power to work tools.
Power and Reliability
Maximum power and reliability are built into the Cat Skid Steer Loader hydraulic system. In addition to providing power to drive the wheels, this system also provides the loader lift and tilt functions, powers the auxiliary circuit to drive work tools and drives the engine cooling fan.
The hydraulic pumps are driven directly off the engine for maximum hydraulic performance and reliability - no belts are used. Pumps are fixed-displacement and provide flow to the loader and auxiliary circuits at 60 L/min (15.6 gal/min) at high idle. Maximum system pressure for the loader and auxiliary circuit is 23 000 kPa and 3335 psi.
Standard auxiliary hydraulics to power work tools is available through quick connect hydraulic couplings that are rigidly mounted to the loader arm. The Caterpillar line of high pressure XT ES and ToughGuard XT hoses as well as O-ring face seals help assure a leak-free system.
Reliability and Cleanliness
Hydraulic system reliability and cleanliness are improved by using single components in place of multiple components, such as the monoblock hydraulic valve and monoblock pumps. Fewer leak points improve reliability and result in a cleaner machine. In addition, hydraulic oil flows through a 5-micron, spin-on filter. A filter restriction indicator is located in the operator station. A 74-micron screen in the hydraulic tank prevents larger debris from entering the system and causing damage to the hydraulic components.
Hydraulic Oil Cooler
A high-efficiency, hydraulic oil cooler lets the Cat Skid Steer Loader work longer and harder in higher ambient temperatures, even when using continuous high flow work tools. The high capacity, hydraulic oil reservoir also helps keep operating temperatures lower.
The Caterpillar Skid Steer Loader heavy duty structures are engineered for years of use in extreme applications.
The SSL main frame consists of two fully welded, heavy duty structures, the upper frame and lower frame. Weld bosses and links are used throughout the frames and provide chafe-free attachment points for hydraulic tubes, hoses and electrical wiring harnesses to prevent damage.
Lower Main Frame
The lower frame has an internal fuel tank incorporated into the design that is protected from external damage. A removable section has been placed in the floor of the lower frame for cleaning ease. The chain boxes are positioned on either side of the frame, allowing easy access to the power train and hydraulic components.
Upper Main Frame and Lift Arms
Careful attention was given to the placement of components within the frame for favorable weight distribution. The upper frame forms the loader towers and fenders and serves as the attachment point for the rear-tilting cab and tilt-up cooling package. The loader lift arms allow for an excellent viewing area to the work tool. The lift arms also protect the tilt cylinders and associated hydraulic lines and facilitate cab access and egress. The loader arms are designed to handle heavy loads without twisting and bending.
Radial Lift Loader Linkage
The radial lift linkage is the most durably designed structure in the industry. Engineered for years of use in the most extreme applications, radial machines have proven to be the longest lasting frames in any situation. From crushing through deep cement with a hammer to breaking through hard clay, these loader arms are designed to take on the more aggressive applications with ease and maximum reach at eye level.
The rear door, which now opens on the right hand side, and the upper engine enclosure is made of thick gauge steel to protect the back of the skid steer loader from impact damage and to house the taillights. The bumper is made up of fabricated sections and incorporates two conveniently located tie-down points for transporting the machine. An optional counterweight is available to add 45 kg (100 lb) to the rated operating capacity. The bumper sits slightly outward from the rear door to protect the body of the machine from dents and scratches to help increase the machines resale value.
All chassis and cab components are corrosion protected using a process called electro-depositioned paint or e-coat. This method is used throughout the automotive industry as a way of providing superior rust prevention and long life. An acrylic topcoat is then applied before the components are assembled on the line for additional protection and durability. Hydraulic tubes and hardware are plated for long life.
Quick Coupler and Cat Work Tools
