If you are looking to upgrade your construction equipment, you might be dealing with some big decisions. The first thing you should look at is how each type of equipment is powered, since this does affect how the equipment is to be used, its reliability, and what types of job it can handle. The two main sources of power include hydraulic power and pneumatic power. Here are some differences between pneumatic- and hydraulic-powered equipment
Hydraulic Equipment Uses Liquid
The main difference between hydraulic and pneumatic types of construction equipment is how they are powered. With hydraulic equipment, it is powered by liquid that is pressurized from a pump to a motor within the various pipes in the equipment. This pressurized method allows hydraulic equipment to be used for heavier loads and bigger projects since the spring actions are minimal.
Pneumatic Equipment Uses Air
With pneumatic construction equipment, it is not powered by liquid, but pressurized air or gas. This equipment typically either uses compressed inert gas or compressed air to provide enough force for using the equipment. While this isn't as good as hydraulic equipment for large and heavy loads, it is great at providing a cleaner process. The gases are exhausted to the atmosphere and there aren't any return lines, so it isn't harsh for the environment when the equipment is being used.
Hydraulic Equipment is Better For Underwater Use
If you have a use for construction equipment underwater, such as with certain types of mining or excavation equipment, it can only be done with hydraulics. Since a hydraulic system uses liquid, this allows it to be appropriate for situations where water is a component. The compressed air component in pneumatic construction equipment is not strong enough to be used under water. Another benefit of hydraulic equipment is that the fluid can often retain heat, so there is a smaller risk of the equipment overheating due to regular use.
Pneumatic Equipment is More Affordable
When you choose pneumatic construction equipment, it tends to be more affordable. This equipment can also be lower in maintenance and last longer in its current condition, so you also save in the long-term costs.
Either way you go, you should be able to find this construction equipment either to buy new or used, or to rent or lease the equipment. This gives you options and reduces the amount of maintenance that is required. It will also be delivered to the job site for you if you decide to rent or lease the equipment.
