Storage and Handling
STORAGE AND TRANSPORTATION OF OFF-THE-ROAD TIRES
Tire stock is divided into new, used, and worn-out tires. This classification facilitates
Example of Grouping
- New tires (Not mounted on rims)
- New/used tires (Mounted on rims)
- Demounted tires ... Unexamined tires Examined tires (worn-out, to be repaired, to be recapped and spare)
- Spare tires (Mounted or not mounted on rims) (re-usable, repaired, recapped)
- Scrapped tires.
Methods of Storage
- New tires:
- Indoor storage ... a cool, dark, dry place.
- Outdoor storage ...ideally covered where possible
- Tires should stored vertically where possible.
- Keep away from motors, power switch boxes and cables, fuels and lubricants.
- Keep a fire extinguisher ready for use.
- Storage methods are the same as those used for new tires.
- Remove stones and nails from tires before storage.
- c.Repair tires if necessary.
- Attach a tag showing the tire's outer diameter for easy reference when the tire isused again.
- If possible, place the vehicle on jacks to keep the weight off the tires.
- Cover tires where possible.
- If the vehicle cannot be placed on jacks, move the vehicle once a month to prevent permanent distortion of tires, and keep the inflation pressure as prescribed.
- Do not paint tires.
- New tubes should be kept packaged and in a cool, dry place.
- Used tubes should be deflated, cleaned and stored.
- Arrange tubes in storage by size.
Methods of Transporting and handling Tires
- Transport tires as they are packed.
- Ideally a tire grab should be used for handling large tyres (29 inch and above) (Fig22.2).
- When using a standard forklift, lift the tire from its outer circumference. Do not insert the forks through the centre or inner of the tire. (Fig. 22-2). Ensure fork tynes are of sufficient length and set wide enough apart to lift on the outer circumference (Fig 22.2)
- Ensure fork tynes are blunt at the ends and free of any sharp edges or slivers
- Lift and chock the front of the tyre before inserting the fork blade underneath. Water can be poured on the tynes as a lubricant. Care must be taken with this task.
- When lifting tires with cranes use wide fibre sling or belts. Do not use ropes. (Fig. 22-1)
Handling of Rims
- Keep rims free from rust. If rusted, take off the rust with wire brushes.
- Handle rims carefully to avoid scratching the beads and distorting rim flanges.
- Do not place a lever or equivalent in the valve holes to lift rims.
