The inertia application of the safety is not required. This device must be installed in traction elevators and roped hydraulic elevators. >> /Length 5668 The actuation mechanism may be a set of flyballs or flyweights adapted to extend radially when a predetermined level of centrifugal force is applied to them. Although a solution may be to provide a special door or hatch to access a governor in a hoistway, such a solution adds cost and space requirements. 1282.

Governors shall be resealed after each test. 18 0 obj The tripping assembly actuates a mechanism to stop the governor rope. The present invention is directed to an overspeed switch system for an elevator where a first switch located in the governor is tripped in response to detected overspeed, and the tripping of the first switch causes a second, remotely located switch to be tripped, whereby when either or both switches are open, power to the elevator system is shut down. Conventional elevator safety equipment includes an overspeed governor for restricting elevator car movement when a predetermined speed is exceeded. 4.A leader in Mainland DC Elevator Parts Lift Gearless Traction Machine, Elevator Spare Parts Lift Gearless Traction Machine, Lift Motor 500kg General Elevator Gearless Motor. endobj Radial extension of the flyballs or flyweights causes them to contact an overspeed switch. <>>> Braking of the governor rope causes the safeties to be engaged and thereby stop the car.

Bistable switches, as opposed to differential circuit breakers, reduce the possibility of problems associated with mixing of different types of signals, such as alternative and/or continuous while providing a fast and reliable signal response. The first switch of the first set, for example, may be for the purpose of tripping the remote overspeed switch while the second switch of the first set may be directly in the safety chain. stream (1) On Type B safeties in which the maximum retarding force does not depend on the pull in the governor rope, the tests shall be of the drop-test type or of the overspeed type.

An old abandoned GoldStar enclosed governor from 1994. Speed governors for car safeties shall be set to trip at over speeds as follows: (i)At not less than 115% of rated car speed. 4 0 obj If desired, a software-based switch may be implemented that is triggered by the overspaced switch on the governor and remains latched until a service technician resets them. When a predetermined speed is exceeded conventional actuation means, such as centrifugal flyweights, trigger a first set of switches and, if the car speed continues to increase, cause actuation of conventional mechanical means to impede elevator car movement. The first set of switches may comprise one switch or any other number of switches, depending on various factors such as the degree of safety redundancy desired or the number of different components dependent upon overspeed conditions. (ii)At not more than the tripping speed listed opposite the applicable rated speed in the following table: Maximum Speeds at which Speed Governor Tripsand Governor Overspeed Switch Operates. These tests shall be conducted to demonstrate that the safety device will function satisfactorily within the range of loads and speeds for which the safety is to be approved.

(2) Figures 3106 A1 to 3106 A7 show the maximum and minimum stopping distances from various governor tripping speeds. I received the Elevator Governor Tripping Speed Chart with lightning delivery. The test shall consist of a physical examination of the escalator parts together with a running test of the escalator without load, including a test of all the safety features prescribed in 7.324 (relating to safety equipment). The sheave drives a shaft or spindle coupled to an actuation mechanism.

(5)Broken rope safeties shall be drop tested. The monostable contacts are configured to maintain contact, in a closed position, during normal operation. When the first set of switches are tripped, they cause tripping of a second set of switches. For reostatic control elevators, the safeties shall be tested by tripping the governor. It is an object of the present invention to provide an overspeed switching system that operates safely and reliably while reducing the time and cost of restoring an elevator tooperation after the overspeed switch has been tripped.

A runaway test is acceptable in lieu of the free drop test when approved safety devices are installed. ])]] Overspeed governors include a switch that opens when the elevator reaches a predetermined velocity such as 110% of rated speed [3]. The tripping of the first set of switches causes them to open and, as a result, the power to the elevator machine and brake is cut, and mechanical braking means in the elevator machine impede elevator car movement. << /Filter /FlateDecode <> (b)Existing installations shall be tested as follows: (1)The car safety of existing installations shall be tested with rated load in the car by tripping the governor by hand at rated speed, within five years of effective date and at least every five years thereafter by a reputable elevator company.

On such tests the governor tripping speed need not exceed 280 feet per minute. In conventional elevator systems having machine rooms the switch to be re-set is conveniently accessible in the machine room by a technician. Excellent., "- "-" , "Control the standard by the details, show the energy by quality". In more recently developed "machine room-less" elevator systems, where the conventional machine room is eliminated, the governor and various other components are located in the hoistway. : US3327811[2]). 3 0 obj Parts of safeties, except springs, shall have a factor of safety of not less than 3.5, and the materials used shall have an elongation of not less than 15 percent in a length of 2 inches. Thus, the first set of switches may be provided with automatic re-setting means and configured to remain open long enough to cause tripping of the second set of switches The automatic re-setting means may comprise, for example, a spring-loaded mechanism and/or a timing control. The system is configured so that when both sets or either set of switches are open, the elevator is inoperable. (4) On Type C safeties, the tests shall be of the overspeed type. The second set of switches is remotely located, preferably in a convenient and easily accessible location such as a control panel in an elevator landing or in a building managers office or a security office.
