GSE Overview

Also referred to as air carts, these units provide conditioned (i.e., cooled and heated) air to parked aircraft when their main engines and auxiliary power units (APU's) are off. They are commonly utilized at non-contact gates, or when fixed-gate or centralized pre-conditioned air (PCA) units are not present.

Air Start Units deliver compressed air to an aircraft to help start the engines during instances when the on-board APU is not operational or there are no other means for starting the engines.


Belt loaders are vehicles with conveyor belts that serve to facilitate the loading and unloading of baggage and other payloads between an aircraft's baggage/cargo compartments and the baggage/cargo carts.

Baggage Tractors are among the most common and recognizable type of GSE at an airport. Baggage Tractors are typically used to move carts containing passenger baggage and/or cargo between aircraft gated on the apron and terminal baggage processing facilities. Some Baggage Tractors can be used to push/tow smaller aircraft, depending on size. The typical airport baggage type towing tractor is rated at 4,000 DBP (Draw bar pull), so it can safely tow and stop around 40,000 to 50,000 lbs. All of these tractors can also have their rated draw bar pull increased by simply adding the necessary counterweight. A 5,000 lb. DBP rated tractor can safely handle loads up to 60,000 lbs approximately. Things such as terrain, weather conditions, and grade will obviously have negative effects on the tractors DBP. We can help determine the right size/capacity tractor based on the customer's needs.

Passenger Boarding Stairs can be towed, pushed, or driven into position (e.g., stair trucks). Boarding Stairs provide a means of loading and unloading passengers at hardstands (i.e., remote parking positions) and in the absence of jet bridges at the airport terminal gate.
