The Caterpillar 446D is specifically designed to aid in heavy workloads like building bridges or completing road works. It is a combination of power and sophistication as seen on its features:
Pilot Operated Controls
The power machine is comfortably controlled using joysticks, adding this excavator technology to the 446D is really a sensible engineering move. Like other CAT backhoes, the 446D utilizes stabilizer controls which make manipulation of the heavy machinery seem effortless. The controls are also ergonomically designed to guarantee low fatigue and stress to the operator.
Loader Performance
The Caterpillar 446D backhoe has increased lift and breakout forces compared to its predecessors of the B and C series. All lifting actions are aided by hydraulic which is designed to do the heavy work smoothly.
Backhoe Performance
The 446D has a design which combines superior bucket power and rotation, excavator style boom, and an extendible stick. The 446D has an increased digging power of 10% compared to the earlier series of CAT backhoes. The depth of digging is also increased by 4 feet because of the extendible sticks.
Work Tools
The 446 D can also be optimized with other work tools to make work easier during construction. It can be coupled with the multi-purpose bucket, loader forks, broom, plate compactor, hydraulic hammer, and a lot more.
The Caterpillar 446D backhoe is powered by a CAT 3114 DIT engine that has an output of 110 horsepower. In coordination with the superb hydraulics the 446D has the following specifications:
- Dig Depth = 16’ 1” up to 21’ 2”
- Bucket Dig Force= 16,950 lbs.
- Stick Dig Force= 11,430 lbs.
- Stick lift force= up to 13724 lbs.
- Loading Height= 14’5” up to 16’7”
- Loading reach= 6’10” up to 10’5”
- Bucket Capacity = 1.5 cubic yards with lift capacity of 9,572 lbs and breakout force of 13,838 lbs.
The engine can also be switched from a 2WD to a 4WD for that extra power. If you are not convinced or needs help with the machine, the CAT customer service is available to help you out with your Caterpillar 446D backhoe.
