The calculation of the use of electricity in the construction elevator
- Use electricity in the field (1) lifting equipment class: tower crane 2, construction elevator 3; According to the table, K = 0.3 cos phi = 0.7 tg phi = 1.02 JC = 40% (temporary load) Pe = 2 times 63 + 3 times 11 = 159 (kW) And then power: PS = 2 times Pe = 2 times 159 = 201 (kW) Pjs1 = K * PS = 0.3 * 201 = 60.3 (kW) Qjs1 = tg phi by Pjs1 = 1.02 times 60.3 = 61.5 (kVA)s

Speed can be divided into low speed elevator (1 m/s), rapid elevator (1 ~ 2 m/s) and high speed elevator (2 m/s). Hydraulic elevators were introduced in the mid-19th century and are still being used in low-rise buildings. In 1852, the United States developed a safety elevator for wire rope lifting. In the 1980s, there was further improvement in drivers, such as the electric motors, which were driven by worm gears to turn the winding drum and balance weight. At the end of the 19th century, the friction wheel drive greatly increased the lift height.s
