Report: Digger Derrick Operating Costs Grow by 81% Over 10-Year Cycle

October 05, 2015

Utilimarc’s newly released digger derrick report shows that the vehicles are driven about 6,000 miles per year, get less than 5 miles per gallon, and are on average 8.5 years old.

Utilimarc collected data from more than 50 of its utility and municipal fleet benchmarking clients and their active digger derricks. The sample shows the average of nearly 12,000 vehicles weighing less than or equal to 55,000 GVWR. The average purchase price of a 2014 digger derrick was $237,225, according to the company.

The graph below shows the operating cost (all parts and labor) net of fuel per mile for digger derricks. As the vehicles age, operating cost per 1,000 miles also increases.

The overall operating cost for digger derricks in year one was $1,430 per 1,000 miles, while in year ten it was $2,589 per 1,000 miles, an increase of $1,159 or 81% over the 10 years. The average operating cost per 1,000 miles for the digger derrick over the same 10-year period was $2,132.

    I think automatic lubrication should be a mainstay on electrical line trucks like the digger derrick or bucket trucks. The 4x4, 4x6, and 6x6 all need this because of the off road environment they go in. That wont eliminate the driveline components needing to be lubed but will definitely cut down on some of the maintenance. That coupled with installation of the Courtsara EZ Lube Spindles for the front axle will make is so the front wheel bearings and axle bushings stay lubricated. That is another area of constant failure and costly expenditures. If a mechanic only has to grease the drive line there is a lot less time spent on a truck to maintain it. The lubrication systems would work great for winter plow trucks too. There is heavy maintenance on these trucks during times of heavy snow and a lot of them are using driven front axles too.
