Introduction
Every industry, from automotive to aerospace or goods manufacturing, needs to manage the transport of heavy materials. Moving a heavy load requires specialized equipment. Most injuries in workplaces like these occur due to negligence. Using frictionless methods for the smooth movement of heavy loads is achieved by using Air film movers, air casters, and battery-powered Machine skates. Using these Machines can make the movement almost frictionless. This article is of interest to industrial manufacturers, logistics managers, equipment handling professionals, and companies in the industry. By understanding the features, applications, advantages, and limitations of each piece of equipment, they can make an informed decision based on their needs.
What are Air Film Movers?
In heavy-load moving industries, such as automotive, Aerospace, and goods manufacturing companies, moving heavy loads of 10 to 600 tons is often done using Air film movers. These air film movers can be customized to meet the specific needs of the industry. The air film movers have sensors that are activated as soon as they are working. They can sense the presence of any kind of hurdle or anything that can cause damage to the air bearing.
How Air Film Movers Work
The operation of the air film movers is quite efficient; they utilize compressed air to form a micron-level air cushion. The formation of an air cushion between the floor and the air film mover is responsible for the frictionless movement of heavy loads. A minimum energy is required to move heavy loads, ranging from 10 tons to 600 tons, with a single air film mover. Manufacturers can obtain an air film mover tailored to their industry’s specific needs.
Main Features
Air film movers have many features, such as:
- This equipment can help reduce the friction involved in moving heavy loads, thereby protecting the ground from damage.
- The load-bearing capacity of the air film movers can be customized by increasing the number of air film mover stations.
- These can be used for indoor small movements. It features omnidirectional movement, allowing it to move in any direction.
- Air film movers must have a constant supply of pressure of 4.5 bars and an air intake diameter of 3/4”.
- The size of the plate ranges from 450-1220 mm.
Applications
Air film movers can be used two or more at a time. These can be used in many industries, like:
- Ship manufacturing industries

- The weight of the object is evenly distributed on an air film mover.
Limitations
Specific requirements must be fulfilled for using air film movers:
- Air film movers require a smooth floor surface for their operation, which is why these can be used only indoors.
- Regular screening for any leakage in the air pressure system is required.
- A constant air supply is required for moving heavy loads; still air film movers have limitations when it comes to moving the maximum heavy loads.
What are Air Casters?
An air caster, also known as air bearings, forms a thin air film between the heavy load and the floor. This results in reducing the coefficient of friction to nearly zero. It is a pneumatic or ergonomic solution for moving heavy loads ranging from 10 to 120 tons.
How air casters work
The operation of the air casters is quite simple and similar to that of the air film movers. The air bearing plates or modules are arranged according to the requirements. Then, the pallets are connected to the air compressor supply, which maintains a pressure of 90 psi (6.2 bar). These air skates can move heavy loads above the floor surface, and the air film reduces friction.
Main Features
The air bearing modules have features that are as follows:
- The load-bearing capacity of a single module ranges from 2.5 tons to over 36 tons, which can be increased by adding more modules.
- The dimensions of air modules are 380*380*50mm to 686*686*50 mm.
- The company’s air compressor must have a pressure of 7 kg/cm² and a volume of up to ≥12.0 m³/min.
- The air caster can move in any direction, provides ergonomic support, reduces friction, and features even weight distribution to protect the floor surface.
Applications
The air caster can be used outside of the industry, so they have applications in many industries, like:
- The locomotive manufacturing industry.
- Air casters can move 1000 tons of a transformer.
- It can be used in electric Machine skates for working and for moving large Machinery.
Advantages
- Air casters feature a high-precision control console with 4-6 buttons to adjust pressure and volume as needed.
- They are reliable and keep the floor intact, and the logistics can use them for more than 8 years.
- The accessories of the air castor movers are easy to install or replace.
Limitations
- The airbag used in the air caster may become damaged and require immediate replacement.
- Air casters required a constant and maintained supply of air from the company’s compressor.
- It is not suitable for rough surfaces.
What are Battery-Powered Machine Skates?
As the name suggests, it is a heavy-load moving Machine operated with a lithium-ion battery. You can move the heavy loads by using a remote which have complete power to control the skate while moving a heavy load. These skates can easily move objects weighing 10 tons to 100 tons.
How Battery-Powered Machine Skates Work
For understanding the working of the battery-powered Machine skates, first you need to know the components used in the operation:
- Tractor unit
- Follower skates
