BOEING 737-400F
The larger, longer-range version of the workhorse 737. Known for its efficiency and payload capacity, this aircraft is a popular choice for short- and medium-haul transport.
High Capacity, Low Maintenance
An Efficient, Medium-Haul Freighter
The Boeing 737-400 is a narrow-body jet powered by two wing-mounted turbofan engines. In its role as a commercial airliner, the aircraft was stretched 10 feet over the 300F and seated up to 188 passengers. The dedicated freighter version, known as the 737-400F, was upgraded by installing large cargo doors and structurally reinforced floor panels to support the loading and transportation of heavy cargo. Although it has slightly less range and higher fuel burn, it can hold more cargo and is preferred for higher-capacity routes, especially when extra pallet positions make a significant economic difference.
The advantages of the medium-haul freighter are its payload capacity, fuel-efficient engines, and low maintenance costs due to its reliability and availability of spare parts. It can operate from smaller airports with shorter runways than wide-body jets, which increases the number of available destinations for shipping cargo.
The aircraft was designed to use relatively short paved and concrete runways typically found at small and large commercial airports. When properly modified, the aircraft can service undeveloped areas where only gravel or unpaved runways are available.

Cargo Capacity & Access
The main deck occupies the space just behind the forward passenger door and ends near the back of the fuselage. The lower deck is separated into two smaller sections located fore and aft of the wing. With the main deck and lower decks combined, the aircraft can hold 5,600 cubic feet of cargo weighing up to 45,000 pounds.
Cargo Doors: The cargo door for the main deck is 139 inches wide and 81 inches in height and located on the left side of the aircraft directly behind the first passenger door and forward of the engine. There is enough space around the door to easily maneuver service equipment. The door swings upward and clear of the doorway and cargo can be loaded using a scissor lift or cargo loader.
The lower deck is accessed through two doors approximately 44 inches wide by 33 inches in height on the right side of the aircraft, fore and aft of the wing. Belt ramps are typically used to service the lower deck.
TYPES OF CARGO
The 737-400F is well-suited for transporting a wide range of cargo, including but not limited to:
Moderate-sized industrial equipment and assemblies.
Oil and gas assemblies and components.
Replacement parts for critical machinery or vehicles.
Specialized tools for repair or maintenance.
Time-sensitive goods.
Emergency equipment for disaster-affected areas.

Range & Routes
The Boeing 737-400F has a non-stop range of approximately 2,300 miles at maximum payload, making it ideal for higher-capacity domestic routes and remote locations throughout the US, Canada, and Mexico.
Airport Requirements
The 737-400F is a narrow-body jet designed to takeoff and land from relatively short paved and concrete runways typically found at small and large commercial airports. If properly modified, the aircraft can service undeveloped areas where only gravel or unpaved runways are available.
Taxiway Width: The aircraft’s length of 120 feet and wingspan of 95 feet allows it to operate on standard commercial size taxiways with a minimum width of 75 feet.
Parking Apron Space: At the minimum, the 737-400F requires a parking apron of 150 feet x 150 feet to accommodate the external dimensions of the aircraft with additional room for ground and service equipment.
Ground Handling: The aircraft requires a scissor lift or cargo loader to lift cargo to the main deck. Belt or cargo loaders may be used to transfer cargo on the lower deck.
Fueling: Fueling may be carried out using large capacity fuel trucks or fueling systems capable of transferring large quantities of fuel. Fuel capacity is dependent on the weight of the payload carried by the aircraft and the range of travel required but can be up to 5,400 gallons.
Power and Air Support: The aircraft is equipped with an internal auxiliary power unit to provide electrical and pneumatic power when the engines are not running. The aircraft may also be connected to a ground power unit to power electrical and pneumatic systems.
Runway Requirements
Takeoff Runway Length: The minimum runway length for a 737-400F at maximum payload is approximately 8,500 feet. This requirement will vary based on altitude, temperature, wind conditions and runway conditions. High-altitude airports with elevations over 8,000 feet may require longer runways due to lower air density.
Landing Runway Length: The 737-400F at maximum payload requires a minimum runway length of 5,000 feet. Wet, icy, unpaved, gravel, or grass runways may increase the minimum landing distance required for safe operation.
Crew
The Boeing 737-400F is operated by two pilots. Additional cargo support personnel may be assigned to the flight by the carrier to monitor the cargo and coordinate seamless end-to-end delivery.

Whether it’s organizing rapid ground transport or securing dedicated air charters, we handle the logistics so you can concentrate on running your business and delivering to your customers.
The Challenge
Your company manufactures replacement parts commercial refrigeration systems used in food distribution centers and grocery stores. A large manufacturer of these refrigeration systems placed an order for 2,500 high-efficiency cooling compressors, a much larger order in a shorter time frame than your company is used to handling. This would be a great opportunity to prove your capabilities and ability to scale up, but it also came with a pretty aggressive delivery deadline. It was an “all-hands-on-deck” event and you recruited a few tried and true helpers to join in to meet the delivery date.
No stranger to shipping vast numbers of refrigeration parts and equipment around the country, you called your regular shipping company to schedule end to end pickup and delivery of the compressors. They weren’t always the most prompt or reliable, but specific delivery dates were rarely an issue, and they were certainly the cheapest. The call center rep couldn’t provide availability or pricing at that moment because their systems were down. They said they would call you back when the systems came back online, so you returned to the floor to assist your team.
The fast pace of production made the hours seem like minutes and you realized you hadn’t heard back from the shipping company. You followed up with them and connected with a different person this time. Again, you explained what you needed, and they promised to call you back as soon as the person who could make those arrangements became available.
