There are not that many equipment with tires within the harbors as most cranes are on tracks, but you do have some for additional flexibility. The RTG cranes will have special RTG tires. Wear resistance is key as RTG tires are not he easiest of tires to change, so you will need to make sure that this is as infrequent as possible. For the tires to be cost effective more relates to that they can exhibit a long service life with limited maintenance.
In addition to the RTG cranes and straddle carriers, you will have a lot of terminal tractors that can move around the container trailers around the terminal. The terminal tractor tires need to be able to handle the heavy load of a full container while it maneuvers around the terminal where you need predictable handling as you move the containers around. A terminal tractor will generally have 6 tires, 2 front tires and 4 rear tires that are double mounted. The tires tend to be designed with low profile, so that they can work in cramped environments with limited vehicle heights. As you maneuver in these tight spaces, you will need tires that allow for precise driving response with predictable handling.
In material handling you will also have forklifts that can handle very high loads, you will have your reach stackers and telescopic loaders. You can also have specialty machines like a timber handler, which has special claws to grip the logs so that you can load them onto a truck or then off a truck for further transportation of use of the timber. All the vehicles that are working within the harbors and material handling field will rely on the durability of high quality tires. Tire failure and downtime tend to outweigh the cost difference between cheaper and the high quality tires.
To ensure that you select the right tire for the right equipment that you plan to use for the material handling, you should check the technical tire manual to make sure that the tire you plan to purchase is intended for the use you are planning. You can find the right dimensions from the manual as well as find out the load limits and the correct tire pressure for the intended tire.
