APASEAL LTD. Bowes House Hailsbam, Sussex.
USE of the tool's weight to assist tyre removal
is the object of the Apaseal Roadall beadbreaker. The edge of the tool is placed on top of the bead underneath the wheel rim, and by releasing a trip lever the end tool slides down over the fixed end of the tool, giving an impact thrust to the tyre bead.
The Roadall can be used with the wheel flat on the ground or raised clear using a dummy hub. The operator moves round the wheel changing the position of the tool until the bead is completely free.
EachRoadall is supplied with one of four end tools—No.1 for large tyres; No.2 for small tyres only; No.3 (with blunt end tool) alternative to No.1 for large tyres; and No.4 (with swan-necked end tool) for heavy earthmoving tyres.
For giant tyres up to 9.00-20 Apaseal offers the David II removal tool. Its enormous pressure on the bead of the tyre is distributed evenly round the entire circumference, preventing damage or distortion. The David 11 is also useful for fitting remoulds or tyres with a high ply rating.
The Fejo-Continental air-operated commercial tyre remover is compact and portable and powerful enough to speed removal of even the most stubborn tyre without risk of damage, say the makers.
