For many years, Undercarriage specialists in DRB produced modules and whole undercarriage systems for excavators and machines

used in various constructional and agricultural applications. With world renowned DRB Rubber Track attached, DRB Undercarriage

Systems promise to provide the best performance and services to our customers world-wide.

Total customer satisfaction is realized by reducing customer’s cost in undercarriage R & D, significant reduction of lead time, and

effective management of the components and parts. DRB strives to become the world’s best provider of undercarriage

system by its never ending innovations.

In particular, DRB introduces the world’s first

Anti-Vibration Undercarriage System which is keeping

vibration to the minimum and maximizing operator

comfort in any machine. To add to the comfort of driving

Anti-Vibration Undercarriage, it allows for longer life span of

parts and tracks due to less vibration and wear during operation.

Designed to minimize overall vibration in the use of operators by applying rubber suspension bridges instead of normal steel bridges at

the frame

Concept

Increasing the comforts over twice as much as normal undercarriage

Merit 1. Less fatigue for the operators

Comparison of track abrasion rate (Result for 300 hours field Test)

Merit 2. Increasing the life cycle of Parts

•Equal durability compared with steel bridge•The world first suspension system for excavators •Absorption of vibration→ Smoother ride(Human) & Less fatigue(Machine)

The Real Voice from Anti-Vibration Undercarriage Users

•It’s much more comfortable and less fatigue on breaking work.•Feel smoother ride when driving on pebbles particular.

- From an engineer of A Japanese excavator maker

•Feel reduction of vibration when driving on pebbles and less impact when it’s out of obstacle. It’s very wonderful.- From an engineer of B Japanese excavator maker

•I could see much less wear of rubber tracks. Also, I felt less fatigue and backache after work.- From 12 year experienced 3ton user

•Especially I feel much less fatigue on breaking work.•I think the most effective work for reducing vibration is crashing because it prevents a boom from being twisted.

I wish to purchase it.

- From 15 year experienced 5ton user
