Document Type and Number:
WIPO Patent Application WO/2005/115907
Kind Code:
A1
Abstract:
A belt device for driving an elevator having an increased standstill holding capability to maintain the stopped state of a car even if oil or water is adhered between a belt and pulleys. The belt (4) is wrapped around the plurality of pulleys (1), (2), and (3) and rotated by the rotation of the pulleys (1), (2), and (3). The coefficient of friction of the contact surface of the belt (4) on at least the driving pulley (1) is set to 0.6 to 3.0, and the contact surface is formed of a wear-resistant rubber having a hardness (IRHD) of 65 to 95 and a Taber abrasion (requirements specified in ISO547-1-1999: wear ring: H18, load: 1 kg, speed: 1000 rpm) of 5 to 300 mm3.
