Caterpillar D Series
The CAT (Caterpillar) 420D and 430D backhoe loaders are the high performance machines within the D series lineup. The 420D boasts 85 HP and a backhoe digging depth of 14 feet when equipped having a standard stick.
The 430D offers 94 HP along with a backhoe digging depth of 15 feet when it really is equipped with a standard stick. By using an extendible stick, you are able to push the digging depth of the 420D to 18 feet and the depth of the 430D to 19 feet, which is very impressive to say the least.
Both D series machines are offered in IT (Integrated Toolcarrier) configurations for applications that benefit from a parallel lift loader linkage and the versatility of quick work tool changes via the use of a versatile hydraulic fast coupler. Applications consist of the use of pallet forks, material handling arms, brooms, and even buckets.
The new and improved pilot operated hydraulic backhoe and IT loader controls will support to make certain smooth, precise operation with decreased effort on behalf of the operator. These backhoes use excavator sort joystick controls, and an optional pattern change valve which allows you to choose the patern of control.
The 205 degree rotation which is offered by the backhoe bucket linkage will make it simpler to dig vertical walls and clamp material when loading trucks. The rotation with the D series is 40 degrees extra than with the C series. Now, the backhoe buckets feature a single pin position, with the bucket link featuring an integrated lifting eye too.
The optional fast coupler you are able to get for the backhoe will allow quickly changes of working tools for increased versatility and flexibility in pretty much all applications.
Both of the D series backhoe loaders use the turbocharged, direct injection, four cylinder diesel engine, with a displacement of 4.0 liters. This engine provides superior lug performance which is mostly on account of the responsive fuel injection system.
The standard power shuttle transmission provides four forward speeds and four speeds in reverse as well. Fully synchromesh in all gears will permit on the go shifting, even though the forward and reverse electric power shuttle will offer instant direction changes by means of powered clutches.
The auto shifting feature will automatically shift between second gear along with the highest gear selected for ease of operation. The auto shift feature has five forward and 3 reverse gears, having a transmission kick switch on the lever of the loader control.
With D series loaders, you’ll also have the choice of standard two wheel drive or all wheel drive, which you’ll be able to engage easily on the go, under heavy load, by pressing a switch that is located on the front console.
The D series loaders from CAT are extremely quick and versatile also, as they’ll move quicker than most types of backhoes on the market. The diesel engines are extremely fast, even though the machine has sufficient traction and control to maintain you moving even in wet or muddy conditions.
The variable load sensing hydraulic system will adjust the flow and pressure of the machine to meet the demands of work with an increased pressure of three,300 PSI. The hydraulic system is tuned to work efficiently with the engine, and it provides full hydraulic force to the working tool on hand at any engine speed you desire.
Unlike other backhoe loaders, the D series will decrease demands on the operator, cut fuel consumption in half, decrease wear on the engine, and enable for quieter operation. To create a long story short – the D series from CAT are among the most effective backhoe loaders that cash can purchase – bar none.
