Mini hoist for tower crane installed outside
1, single cage
2, maximum capacity:200kg or 400kg
3, Middle speed:33m/min
4, Main part welded by robot

The mini building hoist is set up with fixed speed and single cage, used for the lifting of tower crane driver and some minor tools.

Every cage has one or two suits of independent driving mechanism. According to the size of tower crane mast sections, the

mini building hoist can be chosen to install inside or outside of the tower crane.

Driven by rack and pinion can speed up and slow down steadily. It has features such as:

1. Reduce the labour working intensity of tower crane driver, especially for the tower crane height upto 100m.
2. The lifting speed can be tailored if client prefers using frequency inverter.

We can provide tailored design, backing on the strong technical strength of China Academy of Building Research.

Building hoist:
1). Cage load capacity: 2, 000kg
2). Lifting speed: 36m/min, 0 - 63m/min, 0 - 96m/min
3). Mast section: Painted or hot dipped zinc

Mini Hoist for Tower Crane

Q: How does the construction lift fall without electricity: This is not calculated according to the distance, it is calculated speed, when the anti-pendant achieves the rated speed, the pendant should be held automatically. It can't go on.

Q: Is there a specification requirement for the floor door of the elevator to the floor? How high: The door locks must be in the direction of the elevator, and the people on the floor are not allowed to move at will, only the driver will be able to move. The other is that the height of the door must be 1.8 meters high, so that the workers' heads don't reach out to the danger.

Q: How many meters or how many layers should the construction elevator be installed?: Construction elevator is also called construction lifter, alias outdoor elevator or people dual-purpose ladder. The country is not clear how many meters or how many layer must be used, but in some coastal developed cities are now more than 30 meters using construction elevator, some cities also issued relevant rules more than 30 meters must use construction lifter, gantry and hoist is no longer used.

Q: Where is the location of the elevator in the project: Hard to answer, I think should combine the construction plan, adjacent to roadway facilitate material transport, and combining with the construction progress, do not put in sample area, in addition to combined with the construction interface classification and so on into consideration, to say.

Q: How many floors are built to use the construction elevator? With six floors?: The construction elevator, the average layer height above 12 floors need to be used, the hoist machine is not to go up to use the construction elevator to send a person to carry a few light things upstairs.

Q: Safety device for construction elevator: 1. The governor To prevent the hanging basket construction elevator overspeed or fall and set up a safety device, is divided into a unidirectional and bidirectional type two kinds, the one-way speed limiter can only along the direction hoisting cage falling within the speed limit, two-way speed limiter can up and down along the hoisting cage speed effect on two directions. The speed limit shall be tested for performance in accordance with the prescribed time limit. 2. The buffer spring Buffer spring in spring seat connected to the base frame, so that when hanging cage fall accidents, reduce the impact of the hanging basket, at the same time ensure crane cage and weight drops landed into flexible contact, slow down the hoisting cage and the impact of weight landing. The buffer spring has a cone winding spring and a cylindrical spiral spring. Usually, there are two or three cone coiled springs or four cylindrical coils on the base of each cage.

Q: When building tall buildings, the machine that USES to lift concrete to wait for tall building: It should be the ground pump, the center is the tower crane, the construction face is the concrete pump of the cloth machine to the construction method. The advanced cloth machine is the arm bracket of the pump car, can operate with the remote control, is as convenient as the pump car.

Q: There are differences between the construction elevator and the construction elevator: When it comes to the construction elevator, people will immediately think of construction lifter, the construction elevator and elevator is just a different name or have their own respective working principle? By below small make up to you to introduce: construction elevator is often referred to as construction lifter, but construction lifter, including the definition of a broader platform construction also belongs to the construction lifter series.

Q: The maximum allowable deviation of the vertical is the vertical degree when the construction elevator is installed: The maximum allowable deviation for the installation of the elevator rail frame is the following: The height of the elevator rail is less than 70 meters, and the vertical deviation should not be greater than one thousandth of the height of the guide frame. 2, the guide frame height is greater than 70 meters is less than or equal to 100 meters, the deviation is less than or equal to 70 mm. 3, the guide frame is larger than 100 meters is less than 150 meters, the deviation is less than or equal to 90 mm. 4, the guide frame is larger than 150 meters is less than or equal to 200 meters. The deviation is less than or equal to 110 mm. The guide frame is greater than 200 meters and the deviation is less than 130 mm.

Q: What is the need for the sc200/200 construction elevator cable?: The sc200/200 construction elevator cable line should not be below 120 square. Man's ladder 33KW, 5 * 33 = 165KW The tower is 45KW one, 2 * 45 = 90KW The pressure slag welder is estimated to be 25KW Touch welder 1OKW, 5 * 10 = 50KW Other facilities such as mixer, temporary illumination etc. 30KW Total power: 165 + 90 + 25 + 50 + 30 = 365KW One square cable is 5 minus 7A, 380V is 1KW is equal to 2A. That's 730A 730A divided by 5-7 calculates that the cable line should not be less than 120 square.
