The speed limiter operating the car safety gear device should occur at a speed equal to 115% of the rated speed. However, it should be less than: a) 0.8 m/s for the instantaneous safety gear device except for the non-detachable roller type; b) 1.00 m/s for the non-detachable roller type safety gear device; c) for the rated speed A progressive safety gear device of less than or equal to 1.00 m/s is 1.50 m/s; d) is a progressive safety gear device with a rated speed of more than 1.00 m/s of 1.25+0.25/v. For elevators with rated speeds exceeding 1.00 m/s, it is recommended to check the operating speed at the above upper limit. Article 9.9.4 stipulates that when the speed limiter is operated, the tension of the speed limiter rope shall not be less than the following two larger ones; a) 300N, b) twice the force required for the safety clamp device to function.
Pulling the safety gear connecting rod pull arm with 300N pulling force, the whole mechanism is flexible, and the interlocking switch can also operate at the same time. After releasing the arm, the mechanism should be able to respond quickly, but the linkage switch should not be reset. As the linkage moves, the wedge should be able to slide flexibly within the jaws. Under normal circumstances, the gap between the wedge and the rail side working surface should be uniform and should be within 2-3mm.
The above content fully discusses the necessary conditions and basic requirements for the operation of the speed limiter safety clamp system. However, in the inspection of the limit safety gear, it is found that some elevators are not properly maintained due to poor maintenance, which makes the safety device fail to meet the normal working requirements. The main problems are as follows:
1. Because the speed limiter spring is in a state of repeated expansion and contraction for a long time, the speed of the setting movement is changed;
2. The rotating parts are short of oil for a long time, and the increase of the resistance causes the centrifugal swaying part to be inflexible;
3. Due to the extension of the wire rope itself, the tensioning device touches the ground, so that the tension of the wire rope is insufficient and slippage occurs;
4. The connecting part of the connecting rod of the safety gear is lack of oil and rust, so that the lifting force greatly exceeds 300N;
5. The distance between the end of the active lever and the safety clamp linkage switch is too large. When the pull arm is lifted, the switch cannot move at the same time;
6. The clearance between the wedge and the working side of the guide rail is too large, and the wedge can not catch the guide rail when the connecting rod is lifted up;
7. There is too much oil in the wedge. After the arm is released, the wedge cannot be reset, causing damage to the guide rail. The existence of these problems not only makes the system a device, but also makes people feel psychologically paralyzed and potentially harmful. Therefore, it is necessary to strengthen the maintenance of the speed limiter and safety gear to prevent the occurrence of major accidents.

You could replicate theprocedure before going to bed. Last year's game featured 38 episodes of 2KTV. Each of those episodes gives players a chance toearn VC for answering questions and participating in surveys. You can generally earn near 400 VC in the show, and it is prettyinformative overall. When playing as DJ, you'll encounter NBA 2K18's "The Neighborhood." At a MMO-lite twist, it is possible towalk round with multiple (hundreds, possibly, if servers fill up) of other player-controlled DJs, playing pickup games, tradingscores in MT NBA 2k18 minigames or socializing. The existence of other players is generally pointless outside of light rivalry, however; Iended up only ignoring the audience.
2K has gone out the sports gaming genre before to grab new ideas, and with the growth of thisuber-popular Fortnite, it may be time to look outside the sports gaming universe because of its next bit of inspiration. Playersthat have outstanding dribbling skills can feast on the bottoms of competitions who lack the ability to slow their drives to thebasket. Sports Gamers Online made a tutorial video moving over a collection of 2K stick commands, in-game parameters and real lifebasketball principles. Fortnite puts you in and out of matches quickly. If you're not as excellent as the group you are playingagainst, it won't take long to wind up back in the lobby and on the lookout for another match. NBA 2K desires a manner that givesplayers that kind of quick restart.
By way of example, if you find a hoop next to the building your MyPlayer lives in, you couldmove all the way back to the Gatorade gym and attempt to sink long-range bombs. Creating this type of shot would result in asignificant number of points for your total. Cross Play I'm happy you asked. Mind you, even if the NBA 2K18 MT Coins player you're controlling hasreduced evaluations in lateral quickness, it will still be difficult to shield a player with great dribble moves, speed, andagility. less
