| 摘要 | A rescue apparatus comprising a carriage serving as a support for a seat, which can run by gravity on the carrier cable of an overhead cable installation. A brake system permits the regulation of the velocity downward travel on the cable. The carriage and the brake system are so devised as to permit the passing of the grips from which are suspended the loads on the cable and also of the towers. | ||||||
| 权利要求 | 1. A rescue apparatus for an overhead cable transport installation on a gradient wherein the cable is supported by arms fitted on spaced towers and supports loads coupled on the cable, comprising: a carriage with loose carrier wheels able to run on the cable, a lateral suspension articulated on the said carriage devised so as to provide sufficient clearance for the apparatus to pass by the loads, a braking system fixed on to the said carriage with a pair of mobile jaws able to grip the said cable and brake the running of the said carriage on the cable, mechanical means for mechanically linking the said jaws and having a first spindle with eccentric mounted so as to rotate for moving together or away the said mobile jaws and control braking, an operating lever fixed to the said first spindle with eccentric to impart a rotary movement to the spindle, an elastic means for biasing the said jaws into the braking position. 2. An apparatus according to claim 1, further comprising, associated with said jaws, respectively a first and a second jaw-holder lever each having two arms, one of which is pivotally mounted on the said carriage, the said mechanical linking means being designed to link the other arms of the first and second jaw-holder levers and to control the pivotment of the later levers, the said first spindle with eccentric being mounted so as to rotate on said other arm of said first jaw-holder levers. 3. An apparatus according to claim 2, further comprising: a second spindle with eccentric mounted so as to rotate on said other arm of said second jaw-holder lever, a safety lever coupled with said second spindle with eccentric, a connecting rod mechanically linking the first and second spindles with eccentric so as to impart a moving away or together of the said other arms of the jaw-holder levers, when said operating lever is rotated in one direction or the other and a moving together of the said other arms when said safety lever is rotated. 4. An apparatus according to claim 3, comprising a seat and pivot fitting on the said suspension to permit the turning of the seat in the direction of travel of the carriage. 5. An apparatus according to claim 3, comprising A connecting rod mounted so as to rotate on one of the said spindles with eccentric and with a hook capable of engaging the other of the said spindles with eccentric. 6. An apparatus according to claim 5, comprising a mechanical link between the said jaw-holder levers to impart a symmetrical pivoting of the latter and an elastic component pulling the said jaw-holder levers into the position in which the jaws are separated. 7. An apparatus according to claim 1 for an overhead cable transport installation having walkways supported by said towers and extending along a section of said cable. |
