Main Parts of Building Hoist

1. Adopts the most advanced VF speed control device and microcomputer programmable logic controller.

2. Stepless speed control helps eliminate the concussion during start up and braking, steady the operation process, and ensures automated leveling.

3. Adopts open loop V/Fcontrol; the speed control precision can reach ±2~3%. Realizes accurate low speed positioning of the hoist and avoid slipping during downward stopping of hoist.

4. The VF system has current-restriction function, ensuring a small current when motor start up and reducing the concussion to power supply. It reduces the engery consumption and mitigates effects to on site electric equipments.

5. The steadiness during running mitigates concussion to mechanical parts, reduces wears of rack, pinion and the brake and prolongs the spare parts'life.

6. The VF system also has the over voltage protection,low voltage protection, overcurrent, overload and anti-stalling protection functions,

7. The system applies the special software for hoists developed by our company, making the operation more safe and reliable.

Mini Building Hoist for Tower Crane

Q: The working principle of construction elevator: The construction elevator is a kind of common name, its standard name should be the construction elevator, this is a kind of crane machine equipment. Construction lifter adopts modular structure, because it is used in construction process, the elevator needs to be constantly shift with the construction project, therefore its structure must be easy to disassembly and assembly. For example, after the site is used, the elevator is disintegrated and transported to another site for reassembly of construction elevators. So how does the construction elevator work? The construction elevator mainly carries the structural self-forming system, and the construction dependence is low. It more driven by force, drive devices are installed on the hanging basket, through the gear and rack drive system, the mutual cooperation, so as to realize the rise and fall of the elevator. You may have seen gear and rack in the mechanical clock, the gear is round, the rack is straight, and the two bite together to achieve the motion. The elevator work that is common in our residential and commercial buildings is different from the construction elevator. Most of the elevator parts are fixed in buildings, which are mainly carried by buildings. Its movement is achieved through wire rope.

Q: Safe use of construction elevator: In the case of passenger and carriage, the loading shall be uniformly distributed, and the overload shall be strictly prohibited. When the elevator runs to the top and lowest levels, it is strictly forbidden to stop at the collision or lower limit. 7. The driver for leaving hanging basket and while going off work, should be hanging basket fell to the ground, to cut off the total power supply, and the door is locked point, prevent other undocumented workers start the hoisting cage without authorization. Wind up above 6, should stop using the elevator and bring the cage down to the ground. There must be good protection on both sides of the transportation channel. Floor door should be in a normally closed state, its height should conform to the requirements of the specification, anyone shall not open or head out of the door, when the floor door open, the driver shall not start the elevator. Ensure that the communication device is in good condition and the driver should be able to start the lift after confirming the signal. The driver should immediately execute any emergency stop signal on the floor of the operation. The elevator should be installed on a separate ground protection and lightning protection device. It is strictly forbidden to do maintenance work under the condition of the elevator. If maintenance is required, the power supply must be cut off and the sign of "check in, shut off" will be hung in a prominent place.

Q: The construction elevator can not operate during the use of several stages of wind power: The top wind speed is no more than 20m/s, which is level 8, the gale level 17.2-20.7 m/s, I am a tower crane and construction elevator accessories. I hope my answer will help you.

Q: There are two 18-story buildings under construction and tower cranes.: In this case, you do not need to install the construction elevator at the main stage. After the main body is finished, install the tower crane, reinstall, mainly for decorate the vertical transport of the stage.

Q: Is there a specification requirement for the floor door of the elevator to the floor? How high: Layer should be made from steel door frame, Shanghai silk screen, and is equipped with solid and reliable locking device, elevator door layer, the process should be hanging cage crew operations, shall not be under the direct control of elevator lift cage's movement. The net height should not be lower than 1.80 m, and the width of the door should not be greater than 120mm.

Q: Gear rack driven: Driven by two or three worm gear reducers, the ladder cage is a load bearing unit, and gravity is carried by a rack. At rest, the force point is in the meshing of the gear and rack.

Q: Why do you ask the construction elevator to be a certain distance from the structure? Is very close to if not you can not bother to do delivery channel security protection or something, out of the elevator out directly, and attachment should be able to get more easily, to solve. Thank you very much!!: The distance between the moving parts and the building and the fixed construction equipment shall not be less than 0.25 m. The main thing is to prevent the person from the point of view. For example, workers are on the third floor to look down, hanging cage, where is the result now hanging basket is go down from the fourth floor, if not the 25 cm, likely to brush "cut".

Q: How much cable does the construction elevator 44KVA need?: 44 kva should choose 16 + 2 * 3 * 6 square cable, 16 of the 30 ℃ safe carrying capacity is 78 a cable Current I = P/U / 1.732 = 44000/380/1.732 is approximately 67A The construction elevator will not only carry the engineering materials but also the higher frequency, the load calculation will be calculated according to the continuous working system. The cable should be used for the YGTZ special cable.

Q: How is the construction elevator installed: Construction elevator installation 1) the location of the elevator depends on the condition of the site and the equipment, so as far as possible, stay away from the overhead line and keep the safe distance specified. When the elevator is running, there is a lot of danger and should be avoided. 2) the order of installation is: 3) place the chassis on the base and the base pre-buried bolt, and the platform is placed on the chassis, and the basket is placed in the middle of the chassis. 4) to install the standard section, each installation of two standard sections (usually less than 8m) to be temporarily fixed. The wire rope shall be used for the use of the temporary cable, and the joints and supporting points shall be bolted and not tied with the lead wire. 5) the installation should alternate between the two columns. Node bolt specification must according to the aperture matching, not packing, found that the aperture position at the time, can not arbitrarily expanding, more can't to lead wire bundle, instead to avoid loose node deformation. 6) when installing the standard section, pay attention to the vertical degree of the guide, and the line of the guide line should not appear in the line of folding and too big clearance to prevent the collision from running. 7) when construction site conditions permit, it can be assembled on the ground and then hoisted on the whole to reduce the height of the work. Due to the design of the frame, the stress condition of the construction is only considered, so before the whole moving up, the counter can be temporarily strengthened to enhance the bending capacity of the nodes.

Q: Should a fire extinguisher be equipped in the construction elevator?: The temporary building area shall be equipped with fire equipment according to the regulations. In general temporary facilities, each 100m2 is equipped with two 10L extinguisher. If the total area of a large temporary facility exceeds 1200m2, there shall be a special service for fire fighting, such as taiping pail, water bucket (pool), and huangsha ponds, etc. No items shall be piled up around the facilities. Between temporary carpenter's room, paint room, wood and machine tools, each 25m2 should be equipped with a suitable extinguisher. The oil depot and dangerous goods warehouse shall be equipped with sufficient quantity and type suitable extinguisher.
