Henkels & McCoy, a utility contractor based in Blue Bell, Pa., purchased two hybrid diesel/electric trucks using Eaton's patented hybrid solution to continue reducing emissions and fuel usage. The vocational trucks work as medium-duty personnel lift/material handlers and will be used to install power lines. The hybrid trucks are assigned to Henkels & McCoy's operations in eastern Pennsylvania and southern California. Henkels & McCoy is No. 231 on Construction Equipment's Giants list.
The hybrids convert energy generated through braking into stored battery power. The stored battery power is used to assist the truck's power train. The hybrid system is also used to power the hydraulic system of the personnel lift. During the personnel lift operation mode, the batteries are recharged by the diesel engine. The system will decrease fuel usage, emissions, and maintenance for a lower lifecycle cost. The system also reduces noise to enhance the public's satisfaction, and it is capable of supplying up to 25 kilowatts of auxiliary power.
