摘要： An elevator comprising a first governor (121) for braking an emergency stopper (10) engaging a guide rail by restricting the circulation movement of a governor rope (13) suspended in an elevator shaft (1) when the speed of a cage (8) ascending/descending the elevator shaft (1) reaches a first over speed. The cage (8) is also provided with a second governor (42) which brakes the emergency stopper (10) when the cage speed reaches a second over speed lower than the first over speed. Furthermore, an end region drive means (55) is provided in the elevator shaft (1) in order to drive the second governor (42) when the cage (8) ascends or descends an end region. When the cage (8) is descending at an over speed in the end region of the elevator shaft (1), the emergency stopper (10) is actuated by an over speed lower than the emergency brake over-speed in the intermediate region of the elevator shaft (1). Consequently, marginal distance of the cage (8) can be shortened at the end of the elevator shaft and the construction cost of the elevator shaft (1) and the manufacturing cost of a shock absorber (111) can be saved.

摘要： There is provided a first governor (121) which restrains the circulatory movement of a governor rope (13) suspended in a hoistway (1) when the speed of a car (8), the car ascending/descending a hoistway (1), has reached a first overspeed, thereby causing an emergency stopper (10) engaging a guide rail to perform braking operation. The car (8) is provided with a second governor (42). When the speed of the car has reached a second overspeed lower than the first overspeed, the emergency stopper (10) is caused to perform braking operation. Further, end region drive means (55) is provided in the hoistway (1), and the second governor (42) is driven when the car (8) ascends or descends across the end region.
By means of such a construction, when the car (8) descends at an overspeed in the end region of the hoistway (1), the emergency stopper (10) performs braking operation at an overspeed lower than an emergency braking overspeed which would be achieved in an intermediate region of the hoistway (1). As a result, a buffer ascending/descending distance of the car (8) at the end of the hoistway can be shortened, thereby curtailing the cost for constructing the hoistway (1) and the cost for manufacturing a buffer (111).
