AN ELEVATOR SYSTEM (FOR SILOS, RESERVOIRS, WIND AEOLIAN STRUCTURES, ELECTRIC TOWERS, RADIO TOWERS AND FREQUENCY SIGNALS TRANSMISSION TOWERS, ANY OTHER TOWERS AND ANY OTHER HIGH STRUCTURES) WITH TWO EMERGENCY BREAKING SAFETY DEVICE, A SHOCK-PROOF SYSTEM, A MOTORISED (OR ENGINE OR ELECTRIC) WINCH AND TWO LATERAL GUIDING TRACKS

摘要

An elevator system consisting of a platform guided on two lateral guiding tracks. The elevator is operated by a radio-frequency remote control transmitting to a motorised winch at the ground level of structure. The motorised winch unrolls an operating cable to allow the descent of the elevator platform. The operating cable drives a pulley fixed on a driving shaft at the top of the structure, the driving shaft has an inertia brake attached to a safety cable attached to a hook fixed to a shockproof plate attached underneath the elevator platform by compression springs. A second safety braking device is engaged when two spur gears on driving on a gear track collide together due to compression of the springs when the safety cable is activated.
