When the elevator stops at the fully compressed pressure, at least half of the solution should be kept in the coil. 8.4.3 Only one layer of steel wire braid is wound on the conveyor. 8.4.4 The angle (releasing angle) between the steel wires shall not be greater than 4°. 8.5 The load distribution between the steel wires or chains shall be 8.51 At least one end of the steel wires shall be provided with an adjusting device to balance the tension of the steel wires. 8.5.2 The chains connected with the sprockets shall also have an adjusting device at the ends connected to the car and the opposite ends. When there are multiple reversing sprockets on the same shaft, each wheel shall be able to rotate independently. 8-5.3 If a spring is used to balance the tension, the spring shall work under compression. 8.5.4 After the adjustment of the steel wire or chain, the device shall not move violently during operation. B.6 The sprockets and wheels used for guiding and returning functions shall be equipped with protective equipment to prevent the wire from leaving the rope due to slackness and falling off the rope wheel due to looseness. The protective devices used shall not hinder the inspection and maintenance of the rope pulley or sprocket. B-7 Safety equipment
8.7.1 General
8.7.1.1 If the rated weight of the car is greater than 250kg, a safety pin device shall be installed on the car. 8.7.1.2 In the case described in 5.2b>, the safety pin device shall be installed in stages. 8.7.1.3 The safety pin device shall only be activated when descending. When the speed limiter is reached, the safety pin device shall be able to maintain the rated weight of the car and keep the speed at rest. 8.7.1.4 The safety pin device may be instantaneous. B. 7.1.5 In the case of the action of the safety pin device of the new weight, the device specified in 4.2 shall be used.4.4.7. The coils of the steel wire drive should be provided with a belt, the material of which should be compatible with the wire used. 8.4.2. When the straightener is in full compression, at least half of the tension should be maintained in the coil. 8.4.3. Only one layer of steel wire braid should be wound around the conveyor. 8.4.4. The angle (releasing angle) between the steel wires and the rope should not be greater than 4°. 8.5. The load distribution between the steel wires or chains should be 8.5.1. At least one end of the steel wire chain should be provided with an adjusting device to balance the tension of the wires. 8.5.2 Chains that are coupled to sprockets shall also have upward adjustment devices at their ends connected to the car and the opposite ends. When there are multiple reversing sprockets on the same shaft, each wheel shall be able to rotate independently: 8-5.3 If springs are used to balance the tension, the springs shall work under compression. 8.5.4 After the adjustment of the device for adjusting the wire or chain, it shall not move violently during operation. B.6 Sprockets and wheels used for guiding and reversing functions shall be equipped with protective devices to prevent the wire from being separated from the rope due to slack and the wheel from falling off due to looseness: Chain guides shall be allowed, and the protective devices used shall not hinder the inspection and maintenance of the rope wheel or sprocket.
