A cold planer is heavy equipment used to rip materials such as roads and sidewalks. It has an adjustable head that can accurately cut to the desired depth. Large projects include a container to collect the material. It requires skill to operate and protective gear should be worn.
A cold planer is heavy equipment that is used to rip materials such as sidewalks and roads. Suitable for asphalt and asphalt pavements, cold planers are most commonly used by road construction crews. Large construction companies may retain them for specific projects, and they are also sometimes available through companies that provide equipment rental. The cost of a cold milling machine, new or used, varies depending on the type and available features it offers.
The cold planer has a head that can be used like a drill to break up the material so it can be removed. The angle and depth can be adjusted to allow the cold planer to accurately cut to the desired depth. This allows crews to do things like remove the top layers of a road while leaving the bottom layers intact, controlling this stage of the project with a high degree of precision. Readers who have watched roadside personnel remove some of the roadway may have noticed that when the underlying layers are exposed, they are often gouged. This is the result of the cold milling machine drill head.
Large projects include a container that is used to collect the material torn off by the planer. In other cases, crews have the option of loading a second machine such as a dump truck with the material as it is torn, or pushing it aside into so-called “swaths” for later disposal or collection. The cold milling machine can be designed as an attachment for a tractor or other piece of equipment, or as an enclosed motor vehicle that is driven or pushed across pavement to tear it up.
Alternative names for cold planers include pavement recyclers, routers, and pavement planers. Several heavy equipment manufacturers produce cold planers along with accessories and replacement parts that can be used during maintenance operations to keep a cold planer in good working condition.
Using a cold planer requires some skill, because the operator must be able to set the machine to the proper depth and control it. Also, ear and face protection should be worn when using a cold planer because the devices are noisy and chunks of flooring material can be slammed into the operator’s face. Nearby workers should also exercise caution to avoid being injured by the device.
