Net orders for commercial truck trailers dropped 30 percent in April from March after climbing for 18 straight months, according to ACT Research.
The trailer manufacturing industry backlog topped 100,000 units, and is 141 percent higher than a year ago, the Columbus, Ind.-based research firm said.
Net orders for heavy trucks surged 31 percent in April from March, an ordering pace that is creating a bulging backlog that will strain truck production lines.
The April decline in net trailer orders followed a 21 percent month-to-month increase in March and follows a typical order pattern, ACT Research said.
Trailer makers usually have a strong first quarter followed by a mid-year lull, said Frank Maly, director of commercial vehicle transportation analysis and research.
“April net orders were the start of that seasonally anticipated lull,” Maly said. In the first quarter, trailer shipments were up 109 percent year-over-year.
