A cushion tire forklift uses a press-on tire that is made with a metal band and a rubber attached to it. A solid pneumatic forklift has tires that are shaped like air tires.
Most cuhion tires will have a safety bar on the sidewall to show when they will need replacing. A general rule of thumb for all others is to replace them when the wear reaches the op of the iomprint of the size of the tire. Thre reason being is that once the tread reaches that point, 50% of the carrying cpacity is lost.
For cushion trucks, the tire is the only shock absorber on the truck. For solid pneumatic tires, the time to replace them is when all the tread is gone and the tires are completely smooth.
The holes in the sidewalls are made to provide a softer ride than standard solids. The main problem with the holes is that it diminishes the carrying capacity.
Polyurethane tires outlast rubber tires about two to one. The poly tire is designed for warehouse use only. Taking them on the driveway will result in rapid or premature tire failure. The carrying capacity of a poly tire is more than the rubber tire. Most elelctric lifts require poly because of the additional weight of the batteries used to power the lift. Poly tires will also help the batteries to last longer as they have lower rolling resistance. The biggeset disadvantage is that they are made of a harder compound, making the ride harsh.
If you have split-wheel or lock-ring type wheels, you should be able to replace the air tire with a solid tire. Any drop center wheel will not accept a solid tire. Drop center is a wheel similar to a car wheel. You can go from air to solid or vice-versa as you like.
You can move solid tires to the front of the lift and air to the back, or air to the front and solid tires to the back. You must run the same type of tire on the opposite sides of the drive and steer axles.
All tires should be solid, air, or fill. If you put solid tires inside or outside on duals with other tires, there will be a problem. Solid tires will not deflect as much as an air tire of fill tire. The end result will be that a solid tire will carry a majority of the weight and be the first to break down and have problems.
The foam fill is a liquid polyurethane material that is pumped into a tubeless or tube type tire. The material goes into the valve stem on the older style pumps and through the sidewalls on the newer pumps. The foam fill is a two-part material consisting of an A-side and B-side. When the two sides are pumped into the tire, the material mixes and cures out for 24-48 hours, depending on the outdoor temperature. The curing process can be sped up in the wintertime by preheating the fill and keeping the tires warm after being pumped. Air is realeased during the filling process by drilling a hole through the top of the tire. Once all of the air has escaped, the tire will be plugged and then pressurized. The cost of a pump alone is approximately $8,000 for the older models, and $48,000 for the newer or current model.
A foam fill tire rides almost identical to an air tire. Most people would not recognize the difference unless were told.
Adding fill is the same as having the tire water-filled.
Yes, the wheel can be reused as long as the wheel has no cracks, damaged stud holes, or any severe damage.
They are designed to travel 15 mph or slower.
In some cases there is no solid tire made to take the place of a foam-fill tire. Foam-fill tires can be used with lock ring or drop wheels while solid tres must have a flat based wheel to be pressed on. Always check ground conditions. Additonal maintenance problems may occur with solids (e.g. motor mounts, steer axle) when deciding to use solid forklift tires.
The tire size will be on the sidewall of the tire. If the tire size has worn off, you can look on the inside sidewall. have someone operate the forklift and raise the forks above your head. Drive the forklift slowly and observe the tire on the opposide side and check for the tire size. If this doesn't work, back the forklift slowly, turning the wheels to a 45-degree angle and inspect the inside for the tire size. If all fails, obtain the model, serial, and make of the forklift.
The required air pressure is located on the sidewall of the tire. If it is not there, contact us for further assistance.
Solid tires require a tire press, specialty stands, and cages to press the tires.
If there is an actual manufacturing defect with the tire, most problems will occur within the first 45 days of purchase. Problems that occur in longer periods of time are normally due to equipment misuse. Most problems include rapid starts and stops of the forklift, shoving material instead of picking it up, overloading, long runs with the wrong compound of tires, and shifting transmission into forward and reverse before fully stopping the lift.
Most reasons for spinning are covered in the tire failure section; howerver, one way to help stop some of the spinning is to make sure that the solid pneumatic tires you are buying have wire beads in the base to eliminate spinning. the wire beads are built into the tire base and when pressing, they expand as they go onto the wheel, and after pressing they snap into place and tighten the bond between wheel and tire. If the tires have been spinning for a long tiem, it may be necessary to replace both the tire and the wheel.
If the cuts are not too large, you can fill the tire without any problems. If the cuts are too large, upon filling the tire, there is a chance that the tire will fail and the fill will leak. If the tire has only a few small plugs, it is okay to fill it; however, if the tire has several plugs, then a tube may have to be placed in the tire.
Once the machine sits for an ectended period of time, a flat spot will develop in the tire.
The genteral rule of thumb is if the tire contains at least 80% of its tread left, then you will continue to get your money's worth out of the tire and fill.
No, it doesn't. The tire's carrying capacity will remain the same according to the manufacturer's specifications.
For golf carts used in plant operations, you can switch the wheels and tires for solids. The cost is inexpensive since the solid tires will last three times longer than foam fill.
Forklift wheel types consist of a "split" (two halves bolted together). Dayton rims have a lockring and no stud holes. Budd wheels have lockrings and 10 holes for studs. Most split wheels do not interchange with other makes of forklifts. The difference is theat the stud holes and the center holes cannot be aligned.
The lockring can be pressed back onto the wheel as long as the lockring wasn't damaged or sprung.
Some solid pneumatic tires are now made built right into the tire and lockrings are no longer necessary. Extra caution must be used so not to damage the base of the tire while pressing. These types include Click Tires, Quickbase, Sit, Halo, and Limpent.
No, the shock to the machine plus the wear and tear on the machine will not be offset by trying to save money on tire replacement.
A mobile tire press is a tire press that is mounted on a truck or trailer, which can then come to your location and service your equipment on the spot.
No, not all solid and press on tires can be mounted in the field. The mobile press has height and widht limitations. The larger forklift tires will have to be brought in and mounted on a large, stationary press.
Some solid pneumatic tires are now being made in wide profile (WP). There is a moticeable difference in the tread width, as well as the price.
