A terminal tractor, known in the United States as a shunt truck, spotter truck, spotting tractor, yard truck, yard dog, yard goat, yard horse, yard jockey or mule, is a semi-tractor intended to move semi trailers within a cargo yard, warehouse facility, or intermodal facility, much like a switcher locomotive is used to position railcars.
Distinctions between a terminal tractor and a regular road truck are several and noticeable:
- A single-person cab offset to the side of the engine.
- A full-height, sliding rear door for easy access to trailer connections.[3]
- A very short wheelbase, usually with a solidly mounted rear axle.
- A low-power diesel or alternative fuel engine, usually with an automatic transmission.
- A fifth-wheel coupling with an integrated lifting mechanism allows the semi-trailer's legs to remain in the lowered position during movement. 15 inches (380 mm) and 70,000 lb (32,000 kg) of hydraulic lift is typical.
- 12-gauge steel side wall cab construction with 1⁄2-inch (13 mm) steel floors for protection in abusive and dangerous work environments.[4]
- 360-degree view to facilitate five to six moves an hour.
Since off-road versions do not have to drive on roads at highway speeds, a typical top speed is just 25 miles per hour (40 km/h). It is rare for these vehicles to be on highways, so it was very unusual when a pedestrian was accidentally struck and dragged by a yard truck at an intersection in Bellevue, Washington, in February 2014.[5]
Autocar, Capacity Truck, Hoist Liftruck[6], Tico, and Kalmar Ottawa terminal tractors are manufactured in North America. Orange EV manufactures pure-electric terminal tractors in Missouri.[7] Effenco manufactures hybrid systems that can be retrofitted on yard tractors. One of many European manufacturers is Dutch company Terberg who now has distribution in Florida.
