Last Saturday marked the 50th anniversary of the Apollo 11 moon landing. To commemorate this achievement in human events, we wanted to revisit our own contributions to space exploration. In this article we will see how our air handling dolly aided NASA in the Space Shuttle program.
Hovair Systems prides itself on providing heavy load moving solutions, and what better challenge to test that ability than with rocket assembly? In 1978 we designed a Rocket Motor Case Handling Dolly, which was used in the assembly of solid rocket motors.
This dolly had a 12 ft diameter, and a weight capacity of 70,000 lbs. Despite the mass of the fuel containment vessel, it is nearly weightless when cradled in the dolly. This effect is due to our air bearing systems, which use compressed air to lift a heavy object away from a surface. Underneath the vessel are a series of rubber pads that allow free movement of the rocket. The dolly itself rests on a set of air bearings, which allowed engineers to float the entire rig across the factory floor.
In this photograph you can see the record-shaped rubber pads on the air bearings. This is where compressed air escapes and creates an air-film seal between an object and a surface. The same technique is also applied beneath this dolly so it can move to other locations. This transporter was 13×36 feet, and could move Rocket Motor Case Segments weighing 360,000lbs.
Here we see multiple units coming together in the assembly process. With machines this big there is no room for error. Hovair assembly equipment allowed for six degrees of freedom and provided movement within a few thousandths of an inch. This is just one example of the many industries we have helped throughout history. If you enjoyed this article, please leave a comment or share it with a friend.

In a nutshell, air casters are pneumatic tools that make it easy to move large and heavy equipment and machines without damaging the floor. Traditionally, facilities and warehouses have made use of roller equipment, lift trucks, and cranes to move heavy equipment. Not only are such measures impractical, but prove costly for the business and dangerous for nearby employees. Continue reading “How do Air Casters Work?”
It is difficult to overstate the importance of maintenance for heavy machinery especially in industries such as mining, agriculture, and construction. For businesses operating in these industries, large equipment is the backbone of their operations and its optimal performance is necessary to ensure maximum efficiency. Any breakdowns or malfunctions with such equipment would result in significant financial losses and also put workers at risk of injury.
Pneumatics refers to the science of using compressed air to transmit energy and force. A basic example of utilizing pressurized air for the desired function is something as simple as blowing air into a balloon and then letting it zoom around the room. Pneumatic tools are essential components behind things such as drilling machines, machinery that transports heavy objects, and even jet engines! Continue reading “A Brief History of Pneumatics”
Warehouses are typically used to store large volumes of manufactured goods, the management of which isn’t possible without specialized industrial equipment. Whether you’ve recently acquired a warehouse or constructed one from scratch, you’ll need certain tools to get it up and running. Continue reading “4 Industrial Equipment You Need In Your Warehouse”
Despite recent improvements in workplace safety, the material handling industry still remains a dangerous place to work in. According to the Bureau of Labor of Statistics, 2017 saw 5,147 deaths in the workplace, with the warehouse industry experiencing five injuries per 100 employees. Fortunately, almost all of these injuries are easily preventable by implementing a few safety measures that don’t require considerable amounts of investment.
There are always risks involved when working in the vicinity of heavy machinery and equipment. A small malfunction caused by lack of maintenance, human error or any other reason could have potentially fatal consequences.
When it comes to workplaces, health and safety of workers should always be among the top concerns.
According to a research conducted by Bureau of Labor Statistics – United States Department of Labor, a total of 5,190 workers died from fatal work-related injuries in 2016 in the U.S.. While there are multiple threats to the health and safety of employees at work, incorrect lifting and handling of material is perhaps among the leading causes of workplace-related accidents.
