The ROPS/FOPS cabin has electric power window, electro-hydraulic hoist lever, trainer's seat, front brake cut-off switch, backlit LED gear numbers, and optional heater and air conditioner. The hoist lever is electro-hydraulic and fingertip actuated, providing low impact body-down snubbing.
(1) Four-gauge cluster - coolant temperature, oil temperature, brake air pressure, fuel level (2) Tachometer, digital speedometer, actual gear indicator (3) Message center module
Standard and fully adjustable, including an adjustable right-hand armrest. Steering wheel's ergonomic grip improves comfort and control. Low effort steering system and foot-operated retarder reduce operator fatigue. Turn signal lever includes high beam actuator and electric windshield wiper controls.
Exceptional all-around viewing area reduces fatigue and improves operator confidence and productivity. Cab is resiliently mounted and sound-suppressed for a quiet, protected work environment, and is radio-ready.
The four stroke design uses long power strokes for complete fuel combustion and optimum efficiency. High displacement/low speed rating extends engine life and meets China Nonroad Stage II Emissions Standards.

High lugging force during acceleration and less downshifting on grade or rough underfoot conditions. Also effectively matches gear shift points for maximum efficiency.
Electronically monitors operator and machine inputs to optimize engine performance. Independently controls injection pressure, timing and duration over the engine operating range. Rate shaping technology modifies the heat release characteristics of the combustion process for significant decreases in sound and exhaust emission levels.
The ECM monitors key functions and logs critical indicators. The Electronic Technician can access this diagnostic information for easier maintenance and repair.
Final drive and differential torque multiplication of 17.48:1 further reduces stress on the drive train.
Full floating axles are shot-peened to relieve internal stresses and increase durability. Rolled splines also provide increased service life. Cast rear wheels and center-mount rims are mounted using studs and nuts for maximum reliability.
Electronic control of the engine and transmission improves efficiency, lowers operating costs and extends machine life.
Accesses engine and transmission data stored by the Cat Data Link System, and displays the status of all engine parameters.
Displays information on request, and alerts the operator to abnormal conditions with a three-category warning system.
1) Parking/Secondary Piston, 2) Service/Retarding Piston, 3) Friction Discs, 4) Steel Plates, 5) Actuating Springs, 6) Cooling Oil In, 7) Cooling Oil Out
Cat multiple disc brakes use continuous forced oil-cooling. The optional ARC and TCS utilize the oil-cooled rear brakes to enhance truck performance and increase productivity.
Designed and built for reliable, adjustment-free operation providing superior performance and service life in comparison to shoe-type and dry-disc systems. The system combines service, retarding and parking brake functions in a single unit. If hydraulic system pressure drops below a certain level, the spring applied secondary piston automatically applies the brake.
Absorbing the braking forces by shearing oil and carrying heat away, this design extends brake life.
Spring-applied, hydraulically released, oil-cooled disc brakes are located on the rear axle. The front brakes will activate as part of the secondary system, even if switched out of service.
Spring-applied, hydraulically released parking brakes use wet disc brakes in the service system. A toggle switch activates the parking brake.
A Caterpillar patented, two-piston design combines the service, secondary and parking brakes, along with retarding functions.
The ARC electronically controls braking on grade to maintain approximately 2,230 rpm (engine rpm is adjustable from 2,150-2,300 rpm in increments of 10 rpm). ARC is deactivated when the operator applies the brakes or throttle.
With the accelerator depressed and/or ARC turned off, ARC will automatically activate at 2,475 rpm to help avoid potentially destructive and often costly engine overspeeds.
Senses if rear wheel slip exceeds the set limit, and automatically applies rear brakes to slow the spinning wheel.
An on-dash indicator shows the operator that TCS is engaged.
Utilizes normal differential action to provide superior maneuvering in poor underfoot conditions. Also reduces tire scuffing as compared to positive lock differentials used on other systems.
TCS divides torque equally to reduce stress created on final drives and axles when torque is transferred to one side.
Should sensors fail, the normal differential action is still available to maintain control and steering.
Maximum payload in 3-5 passes with matched Cat loader in material over 1700 kg/m³ (2,900 lb/yd³).
Efficient in most construction and mining applications, but excels on rough haul roads and steeper grades.
The 773E frame uses 20 castings in high stress areas with deep penetrating and continuous wrap-around welding. Mild steel provides flexibility, durability and resistance to impact loads even in cold climates.
The ROPS attaches securely to four castings welded into the frame.
Open design reduces overall removal and installation time, lowering repair costs. Repairs can be made without preheating in ambient temperatures above 16° C (60° F) using readily available welding supplies.
Four independent suspension cylinders absorb shocks. Rear cylinders allow axle oscillation and absorb bending and twisting stresses. Front cylinders act as steering kingpins, for maneuverability and reduced maintenance.
Allows 30-50% faster engine service (changing most oil and filters). Improves service scheduling, allows servicing during normal work hours and reduces total engine service time.
The machine platform provides access to the air tanks, brake master cylinder and make-up tank; engine oil level; air filters; steering hydraulic tanks; and battery compartment.
Easy to change, radial seal filters reduce air filter maintenance times.
Simplified servicing and the elimination of spillage are benefits of vertical, spin-on filters.
The Caterpillar worldwide computer network locates parts instantly to minimize machine downtime.
