Chip sealer unit rides on sturdy frame

Seal-Rite’s 550-gallon chip seal trailer is built on a 5-inch channel frame with diamond deck fenders. An enclosed front deck with side gates holds blower, hand tools, buckets and other miscellaneous gear. The unit rides on 16-inch tires with 6,000-pound axles and electric brakes. The four-paddle, variable speed agitation system is hydraulically driven and operates in forward and reverse. A 1.5-inch Graco air-driven diaphragm pump delivers up to 90 gallons per minute for heavy sand loads and automatically shifts to neutral when valves are closed.
