it is economical. Mr.Reed. two people operate the CAT-1 generally. the machine has digital hydraulic controls and a wide-vision cab that gives the operators clear vision and maximum flexibility at all times. it has a 350-horsepower GMC engine that operates at five different speeds. perhaps the maintenance efficiency is also an attractive feature. there is a computerized cyinder cooling system that prevent damage to the cylinder walls. this feature is a significant improvement over your current boring machines. the machine can bore 5 1/2 feet below ground level and can bore up to 30 linear feet at a time. the total height of the machine is 10 feet. what's more,it passes all of ALDOT's (Alabama Department of transportation) requirements for highway projects.
