The elevator manufacturer introduces the application and development of the elevator. The elevator is a construction machine that uses a cage to carry people and carry objects along the guide rails. It is mainly used in the construction of high-rise and super-tall buildings, as well as in the vertical transportation of fixed facilities such as warehouses, docks and towers.
The lift was used in construction in the 1970s. In the actual 70s, Zhongqi developed the 76-type construction elevator, which adopts single drive mechanism, Wudang vortex speed regulation, cylindrical worm gear reducer, pin-type coupling and mechanical block-type speed limiter. The rated lifting speed is 36.4m/min, the maximum rated load is 1000kg, and the maximum lifting height is 100m, which basically meets the needs of high-rise building construction at that time. In the 1980s, with the rapid development of China's construction industry, the continuous increase of high-rise buildings put forward higher requirements for elevators. More elevator manufacturers emerged in an endless stream. Based on the introduction of digestive imported elevators, SCD200/200 was developed. Type construction lifts.
The machine adopts double drive type, special motor, plane double enveloping worm gear reducer and conical friction bidirectional speed limiter. The maximum rated load is 2000kg and the maximum lifting height is 150m. The machine has high transmission efficiency and nowadays. The anti-falling safety device also increases the rated load and lifting height, and achieves the technical performance of similar foreign products, basically meets the construction needs, and has gradually become the basic model of the most used construction elevators in China.
In the 1970s, due to the continuous emergence of super high-rise buildings, the operating speed of some elevators could not meet the construction requirements. Some elevator manufacturers produced higher speed elevators, and the hydraulic elevators and frequency conversion speed elevators were born. Its maximum lifting speed has reached more than 90m/min, and the maximum lifting height has reached 400m. However, the overall performance of the hydraulic lift is lower than that of the variable frequency speed control, so the application is very small.
In the same period, in order to meet the construction requirements of special buildings, inclined and curved elevators appeared.

Fiberglass Mesh is based on Glass Fiber woven fabric as substrate, the polymer emulsion coated with immersion resistance. So it has good alkali resistance, flexibility and latitude to highly tensile resistance,can be widely used for building internal and external wall thermal insulation,waterproof, anti crack.
It has Good chemical stability. Alkali resistance, acid resistance, water resistance, anti erosion,cement and other chemical corrosion; and resin strong adhesion, easy to dissolve in the styrene. High strength, high modulus, light weight.Good dimensional stability, stiff, smooth, not easy to shrinkage, good positioning capability.Good toughness. Anti impact performance is good.Mildew,pest control.Fire prevention, thermal insulation, sound insulation, insulation.
Application
(1) Fiberglass mesh for marble reinforcement
The fiberglass mesh for marble reinforcement is characterized by excellent fitting positioning, high strength, etc. Fiberglass mesh is woven by fiberglass yarns, which is coated by alkaline resistant latex.
This kind of product is usually used to do reinforcement for stone, mosaic, cement, wall materials, roofing, plaster, etc.
(2) Resin coated fiber glass mesh
Resin coated fiberglass mesh has the functions of waterproof, erosion resistance, long service life, etc.
The special resin coating on the fabric can minimize the distortion, and is compatible with various materials.
It is an ideal engineering material to be used in broad construction fields, such as marble & mosaic backing,road surface, water-proof and preventing cracks, etc.
(3) Fiberglass mesh for concrete
The fiberglass mesh is made of glass fiber. Special technique for weave is required to obtain this kind of
product. This kind of product has strong alkali erosion resistance and stability, long service life, etc., and
it is widely used in the field of decoration and construction.
(4) Fiberglass mesh for wall
Fiberglass mesh for walls is characterized by alkali resistance, stable dimension, good toughness, fire
protection, etc.
It is commonly used in the field of GRC wall panel, wall insulation, fire resistant board, reinforced cement
products, other decoration material, etc. Different sizes are available according to customers`
requirements.
(5) Fiberglass mesh for gypsum board
Fiberglass mesh for gypsum board is a very popular in the construction and decoration industries.
Many of its merits build and enhance its good fame, such as strong bonding with resin, thermal insulation,high modulus, light weight, excellent durability, etc. This kind of product can be used in the field of gypsum board and some related fields.(Fire board, interior and exterior walls, asphalt roofing, rubber products, etc.
