Airman Products gave members of the media their first glimpse of its new Automated Landing Gear Deployment and Retraction Technology during a press conference at the 2020 ATA Technology & Maintenance Council Annual Meeting in Atlanta, Georgia.
With the flip of a switch, Airman’s patent-pending device eliminates the manual cranking required to raise and lower a trailer’s landing gear, reducing driver exposure to a variety of musculoskeletal injuries, including damage to shoulders, knees, the back and upper body.
Jim Babbitt, vice president of sales for Airman, told reporters that the 15-pound, electrically driven unit can be OEM-installed or retrofitted in less than an hour and is compatible with all existing landing gear makes and models. Using the new technology, a driver can effortlessly deploy and retract landing gear in less time than it would take to do either operation manually.
“The fleets we’ve surveyed tell us that shoulder, back and rotator cuff injuries are at the top of their list for workers’ comp claims, and that cranking landing gear up and down can cause or exacerbate these injuries,” Babbitt said. “Truck driving is already a physically demanding profession, so our automated system focuses on one primary stressor, making trailer drops and hookup operations safer and faster, while improving the truck driver experience and as a result, driver retention.”
Babbitt said the sheer repetitive motion of cranking can tax muscles, tendons and joints, particularly in the case of aging drivers, and the fact remains that the median age of truck drivers continues to rise.
“Depending on the equipment and circumstances, it can take between 50 to 60 crank arm rotations to get the legs on a trailer’s landing gear to the ground, and this task can keep some otherwise great drivers from working or coming back to work,” added Shane LaHousse, vice president of engineering for Airman. “Operating the crank arm can be awkward and physically taxing, even if the driver is young and uses the proper technique for landing gear operation, so we’ve taken this task out of the driver equation by automating it.”
LaHousse said the Automated Landing Gear Deployment and Retraction system also makes it possible to increase lot utilization, by enabling trailers to be parked closer together. Because no crank arm needs to be accessed, and the controller is mounted just under the trailer apron, tighter trailer positioning is possible.
Easy to Install
According to Babbitt, the system comes complete in kit form with all components and mounting hardware included. Installation is simple. It requires the removal of just two bolts on the landing gear crossbar, the attachment of the Airman landing gear actuator and the reinstallation of the crossbar.
The electrical interface is uncomplicated, requiring only a simple 12-volt power supply. The unit’s solid-state unit control box mounts under the trailer, and its two-way toggle switch user interface mounts to the side of the trailer frame rail for easy access.
Once installed, the unit requires no maintenance, except periodic replacement of its dedicated battery, as needed, according to the company. Airman’s trailer landing gear actuator is self-contained and requires no lubrication.
“Some landing gear manufacturers offer automated systems now, but they are expensive, upgrading requires discarding an existing drive leg, and if the landing gear is damaged, may require complete replacement,” Babbitt said. “Not only is the Airman system about half the cost of other systems, it also works universally with all existing landing gear makes and models, and doesn’t have to be replaced if the landing gear is damaged.”
Babbitt said that currently, fleets would be able to outfit trailers with the new automated landing gear system for approximately $700 per unit.
Fleets with trailer populations made up of multiple trailer brands fitted with varying types of landing gear can now upgrade using one piece of equipment and one single source. So, whether a fleet is ordering the Airman Automated Landing Gear Deployment and Retraction Technology on new trailer builds, retrofitting its existing trailers, or both, it will still be increasing its parts inventory by just one SKU, noted the company.
During the development of the Automated Landing Gear Deployment and Retraction Technology, Airman conducted temperature, shock and endurance testing in its own lab. As part of the evaluation, units were put through the equivalent of 10 drop and hook cycles per day for a period of 10 years, or 36,000 cycles, with no observable wear and no failures.
The product is now undergoing final fleet field-testing on trailers operated by both regional and national carriers.
Automated Landing Gear Deployment and Retraction Technology is expected to be in commercial production by the third quarter of 2020, and the company can help fleets and OEMs with specification information now. The product will come with a five-year warranty standard, and a seven-year warranty is available under a fleet agreement.
