2, structure is complicated, and how relatively costly accessory is.
3, there is congenital deficiency in design concept:
A, motor and change speed gear box rotating speed are very fast, but actual effect is whole ladder completes the operation time about 60 seconds, do not meet Quick rescue requirement.
B, tooth bar length about 5 meters and width only 10 millimeters, be fixed on aluminium section bar by mosaic mode it is difficult to ensure that tooth bar flatness (junction of especially every toothed rack), produce and roll during operation, upper and lower jitter phenomenon.
C, due in the middle of wheel and rack the speed of service very fast, not only noise is big and does not has enough moments of torsion to make load less, load capacity ＜ 120 kilograms.
D, owing to using air spring to reduce lower slip resistance, can glide suddenly when ladder center of gravity runs to vehicle rear, when air spring starts to act on, has there is slippage phenomenon in sliding force, this is the relatively hazardous situation of ratio, the lighter damages tooth bar, air spring can be twisted off time serious cause and tumble, damage to personnel and equipment.
E, control system are simple, and the most upper and lower two travel switches, as spacing, be once in an emergency and cannot effectively be disposed.
Above-described this device does not meets fire-fighting and rescue industry high security, high reliability, requirement rapidly and efficiently completely.
