provided by bent-tube tyre cages is offered by the Ammco heavyduty inflation chamber marketed by HTC (Nottingham).
The chamber is completely enclosed with a viewing window of 12.5mm (1/2in) bullet-proof polyc.arbonate sheet. It is constructed of 6.3imm (3/4in) steel reinforced with four rib rings of 50mm (2in) square angle iron. This is claimed to be secure against wheel, rim and tyre explosions, split-rim shrapnel and air blasts.
An added safety feature is a delay mechanism in the door lock that prevents it being opened for three minutes after tyre inflation has been completed.
Two versions of the chamber are available. One is for tyres up to 1.2m (48in) in diameter; the other is for larger ones.
