- The driver of the elevator ladder cage is driven by two or three worm gear reducers, which carry heavy lifting parts, and gravity is carried by the rack. At rest, the force point is in the meshing of the gear and rack. It is the main balance between the rewire rope and the ladder cage and the relative motion. For heavy can improve dynamic performance, a heavy on the ladder cage running more smoothly, when a fall, fall of heavy can slow down the ladder cage speed, it should be said that safety performance is better.s
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
