Structure of SC300/300 Building Lifter Description

 

To serve the increasing demand for highrise construction, we developed the high speed VF hoist, with a max.lifting speed of 96 m/min.

It has the following structure:

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/F control: the speed control precision can reach ±2~3%. Realizes accurate low speed positioning of the hoist and avoids 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 energy 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 System applies the special software for hoists developed by our company, making the operation more safe and reliable.

FAQ of SC300/300 Building Lifter

 

Q: What is the building hoist main purpose? 

A: Building hoist equipped with double or single cabin to transport the materials and labors up and down. It's the ideal 

construction equipment for vertical transportation in the field of construction.

Q: What is the main structure of building hoist? 

A: The P/M construction hoist mainly contains metal structure, driving system, electrical control system, cable guide & protection system, electrical top crane and safety device.  

Q: What is the meaning of the building hoist’s code?

 A: Take SC200/200 for example: “SC” stands for rack and pinion hoist, “200/200” stands for double cage and capacity is 2 tons per cage. “SC200” stands for single cage and capacity is 2 tons. 

Q: What is the dimension of the cage? 

A: Normally the cage dimension is 3X1.5X2.5M (L/W/H) for 2t type hoist. Details should be checked according to our quotation sheet. Also, the size can be customized according to the factual site condition.  There are two doors (entrance& exit doors) for each cage, It can be produced as up & down sliding or ramping model for safety and convenience.

Q:Why is the construction elevator not so close to the structure?
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:The staff on the construction platform shall not exceed the number of people
Different models have different load rating and platform lift platform size, this depends, suzhou new aluminium alloy elevator, Lin professional aluminum alloy lift platform.
Q:How does the elevator operate
Responsible for operating elevator, maintenance, maintenance and safety. See what kind of elevator and workplace you are working on.
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:6 layer of brick and concrete construction project, have tower crane still need construction elevator?
Very cow! Six floors of brick and concrete construction projects have tower cranes. No construction lifts are needed.
Q:Is the elevator detail a construction plan? Do you have a detailed picture of the elevator?
You're talking about the elevator or the elevator shaft, the elevator is the equipment, the elevator manufacturer has the working paper. As for the elevator well according to the data of zxtech figure design, general construction diagram and structure diagram, industry make a steel cylinder or cone steel structure party sometimes out construction diagram, according to the structure of the construction
Q:The elevator is banned from using elevators for more than a class of high winds
When the wind speed is more than 13 meters per second, the installation and disassembly is forbidden. When the wind speed exceeds 20m/s and the weather, such as hail, the elevator should not be used. This is the norm M/s is about 8, and 13m/s is about 6
Q:How to set up the construction elevator?
According to drawings, find the embedded at the scene near the level of architectural axis positioning and high elevation line (50 wire or 1 m wire) location and double-check, axis dividing levels as much as possible in accordance with the size distribution. Find out after each axis, measuring building contour, and map measure the buildings, and building construction drawing contrast, timely transfer measurement results to the designer, designer analyze the error and make changes
Q:How many guides are in the construction elevator
The guideway hydraulic platform is a non-shearing hydraulic platform, which is suitable for the transport of goods between low floors. The product hydraulic system sets the emergency anti-falling, the upper and lower door interaction chain each floor and the elevating platform work mesa both can set the operation button, achieves multi-point control. The hydraulic electric appliances have optional safety configuration: emergency stop, overload alarm, deceleration adjustment block, leakage proof overload protection, etc. The product structure is strong, the load is large, the elevation is stable, the installation maintenance is convenient, is the economical and practical low floor space to replace the elevator's ideal cargo transport equipment. According to the installation environment and usage requirements of the platform, the different configuration can be selected for better use. Features: minimum height of 150-300mm, suitable for unexcavated pit, at the top without lifting, is the preferred lifting device for transporting goods between lower floors.
Q:How does the driver of the construction elevator do the search for a sudden power failure
There are clear rules for the safety of construction machinery (JGJ33-2001). 6.12.17 when the elevator is running in an existing abnormal condition, it should stop immediately and take effective measures to reduce the cage down to the ground level, and keep running after the failure. When the electric is out of control in operation, the stop button should be pressed immediately. The stop button is not allowed until the failure is ruled out. 6.12.20 when elevator in the operation of the midway stop due to power outages or other reasons, can be manually, the end of a motor brake electromagnet manual release slowly shake handshandle pull outward, slowly slide down the ladder cage, ladder cage fall shall not exceed the rated speed, manually drop must be conducted by professional maintenance personnel manipulation.
