Tandem Axle

Manufacturer: Caterpillar (CQL)
Leveraging Caterpillar's design and experience on the motor grader tandem axle
Features the NO-SPIN differential in the tandem axle to ensure powerful blade pull even under bad underfoot condition
All drivetrain components in the tandem axle are oil-bath lubricated which greatly extend the service lifetime and reduce maintenance cost
4 outboard disc service breaks located at the 4 tandem wheels provide maximum brake capability and serviceability

7-Hole Linkbar

Designed to improve productivity in multiple applications
Center hole: long straight blading, most finishing and light to medium windrows
First and second hole: moving large windrows, cleaning shallow ditches
Third hole: cleaning deep ditches, cutting ditch back slopes and high bank slopes

Load sensing variable piston pump + Proportional Priority Pressure Compensating (PPPC) valves specially designed by Caterpillar
Hydraulic flow is proportioned to ensure all implements operate simultaneously allowing ease of multi-function control for optimizing working efficiency
World-class variable displacement piston pump efficiently reduces power consumption and hydraulic system heat, improving fuel efficiency
Load-sensing hydraulic system provides consistent and precise blade movement, improving equipment performance
Inboard lock check valves within PPPC, prevents inadvertent cylinder movement and potential leaks

A-frame tubular design drawbar provides maximum strength and durability against the load transferred from the blade, up to the circle and into the drawbar
Adjustable shims in the drawbar ball joint maintain the precision of blade positioning
Replaceable drawbar ball (bolted - not welded) for less service time and cost

Designed to take high stress load and wear
Large throat clearance allows material to flow freely along the blade curve reducing driving resistance

(optional)

The standard cooling package provides high reliability in 43° environment temperature and adjustable up to 50° if needed

Feature adjustable shims in the ball studs to keep the tight tolerance for a longer service time before replacement

Flanged box section design removes weld from high stress areas, improving reliability and durability
Top and bottom plates running from the front bracket all the way to the articulation hitch provide maximum consistency and strength
Provides optimized distance between the frame and drawbar for maximum blade positioning and operation

3-point contact for safe mounting and dismounting
Mounted on the front frame providing exceptional visibility for the operator for the critical line of sight to the front wheels and to the moldboard even when the machine is articulating

4 air valves on each cylinder for better fuel efficiency
Provides good high land operation performance, low fuel consumption, low noise, reduced pollution emissions, high reliability, and durability
