Classification of steel rope

The steel rope is divided into two types hemp core and steel core.  according to the rope core. 
(1) The hemp core is divided into two types: natural fiber core (NF) and synthetic fiber core (SF).
The fiber core has the following characteristics: the fiber core wire rope is soft and has good bending performance. The fiber core acts as a buffer when the steel rope is subjected to impact and impact loads during operation. Natural fiber cores store a lot of oil. When the steel rope is working, it has sufficient lubrication inside and can slow the corrosion of the steel wire. Synthetic fiber cores (such as: polypropylene, polyethylene) have strong toughness, no water absorption, acid resistance, alkali resistance, corrosion resistance, and extrusion resistance. The steel rope is not easily deformed during dynamic load use, and the diameter is uniform and stable.
(2) The steel core is divided into two types: independent metal core (IWRC), parallel tantalum core (CFRC) and independent metal core (IWSC).
The metal cord steel rope has the following characteristics: the metal core steel rope has large breaking force, resistance to extrusion and high temperature resistance.

Brief analysis of escalator handrail

Price difference of escalator handrail belts: Handrail belts are usually composed of styrene-butadiene rubber (SBR) and natural rubber. The formula of the handrail strap itself is different, which directly affects the stability and life of the escalator handrail. Shaanxi Sanjin Elevator Fittings Co., Ltd. has been cooperating directly with the manufacturer of brand escalator handrail supply many years,could offer different kinds of handrails,such as Mistubishi,KONE,Schindler,Thyssen,fujtec,OTIS escalator handrail . The formulation of the factory is stable, the material is high quality, and the product can be used for 3-5 years without any problems. Therefore, the cost is relatively high, but the price is reasonable because of the large sales quantity. Nowadays,In order to compete with others, some small factories may use reclaimed rubber, which is rechargeable and has a life of only 1-2 years. Therefore, the price is lower. When choosing the supplier of eacalator handrail, please consider the cost-performance ratio comprehensively, and it is better don't only focus on the price.

In addition, when the handrail is installed, it should not be too tight, will cause fever situation,also will affect the life of the handrail.

Invisible Wheelchair Lift

Sesame Invisible Lift is the ideal solution for buildings where you need to have a wheelchair lift but you want it to be hidden, blended with your interior.

For rises below 1000mm, the Sesame patented wheelchair platform lift offers a practical disabled access solution with a modern, stylish exterior that belies its simple, user-friendly operating system. The lift is built with a unique wheel stop which is designed to prevent wheelchair wheels from moving around on the platform once in position.

When a user presses the lift up button whilst on the lifting platform, the wheel stop rises a total of 100mm before the lift itself rises, therefore stabilising the wheelchair and preventing it from rolling off the platform while in motion. Users will feel 100% safe and secure when being elevated on the lift.

TWIN two elevators in one hoistway

The idea of having two independent elevators in the same shaft dates back in the 1930s, but it took modern-day technology to turn it into the reality. To make this system work and achieve intelligent control ThyssenKrupp needed to use advanced destination dispatch system.
ThyssenKrupp is comparing the efficiency of TWIN technology to four shaft elevator group. In case you decide to use TWIN you will have one shaft less – two TWIN systems and one regular single elevator system. This means more floor space, but in case one TWIN system goes down, it means more inconvenience.

The two TWIN cabs are prevented from getting too close by a quadruple redundant safety system: intelligent allocation of calls; automatic monitoring of minimum safety distances; emergency stop function if the safety distance is breached; and automatic engagement of the safety device in the extremely unlikely event that the first three stages fail. The TWIN system has been fully certified for safety by the German TÜV inspectorate.
In my opinion, the system would be very efficient in office buildings where companies reside on multiple floors and travel between a few floors is required.

Elevator Motor That Helped Save Thousands

This article appeared in the Downtown Express

By Julie Shapiro

A 10,000-pound elevator motor that shuttled hundreds of people a day at the original World Trade Center will be part of the National Museum's permanent exhibit.

The exhibit will also tell the story of John Menville, who arrived at the World Trade Center in 1969 to install the elevators, on 9/11, thousands of people, including Menville, used the elevators to evacuate. When the first plane hit, Menville's immediate thought was of how long it would take to repair the elevators.

When Menville, now 65, helped install the massive 8-foot-by-5-foot motors, called 339 machines, they were the first in North America and the biggest in the world. The only place they had ever been used before was in South African diamond mines.

After installing the elevators, Menville and his coworkers from Otis Elevator Company got to test-ride them, flying through the building at 1,600 feet per minute.

The elevator motor will sit at bedrock in the museum, in a vast corridor dotted with other large objects, like twisted steel and crushed emergency vehicles. Visitors will pass through the gallery on their way to the primary exhibit, where they will see the story of 9/11 told through the eyes of the individuals who experienced it.

The difference of two decode tools of Monarch

Usually, when our lift locked suddenly, and we don't know the passwords. How to solve?  Obviously, use the decode tool.

Regards the tool, here are two types, which depends on its main board version.

1. Ordinary tool, useful for the main board version under V18.0. Decode function only.

2. Full-function tool, useful for main board version above V18.0. Decode and test function together. Workable for Monarch, as well as STEP.

Full-function can replace ordinary one completely.

An elevator earthquake sensor is a device that is used in conjunction with an elevator control system to enable an elevator to enter a regulated operation before or during an earthquake.

Before the earthquake, the elevator seismic switch detected the seismic wave in advance, and the output alarm contact control elevator control system enabled the elevator to open the door on the nearest floor, releasing the passengers in the elevator, and maximally saving the life safety of the passengers. Elevator equipment is not damaged.

There are many famous brands earthquake sensor stocked by Sanjin, Omron, Toyo V757N1-F etc.

Escalator Handrail Belt

Elevator Traction Belt

Vibration problem in elevator operation

An elevator is an electromechanical device that carries objects by moving the car. During the operation of the elevator, the car of the elevator will vibrate with the movement, which is the most common problem of the elevator. The vibration will be comfortable for the passengers. The main factors are as follows:

1. The mechanical movement part of the traction machine is the most common source of vibration. It is necessary to select a traction machine with high bearing precision and high installation accuracy.

2. The base of the mainframe is supported on the load-bearing beam. If there is no isolation rubber, the vibration of the traction machine will be transmitted to the machine room and the hoist-way through the load-bearing beam. Therefore, the rubber is required to be isolated.

3. The suspension center of the car deviates or compensates for the suspension of the cable, and the eccentric load of the car causes the car to generate an unbalanced force, causing a strong jitters.

4. The jitters caused by the uneven torque and tension of the wire rope.

5. The verticality of the car rail installation and the gap and step of the rail joint are important reasons for horizontal vibration. Strict quality control is required for the mounting and installation of rail brackets and guide rails.

Elevator safety equipment- speed governor

The elevator speed governor is one of the safety control components in the elevator safety protection system.

When the elevator is running for any reason, if the car is over speed-ed, and even the danger of falling, and all other safety protection devices are not working, the speed limiter and the safety gear are linked to cause the elevator car to stop. live. It is the safety protection device of the elevator. It monitors and controls the speed of the car at any time. When there is an over-speed condition, that is, 115% of the rated speed of the elevator, it can send a signal in time, and then generate a mechanical action to cut off the power supply circuit and brake the traction machine. If the elevator still cannot brake, the safety gear installed at the bottom of the car will force the car to stop. The speed limiter is the command sender and the safety gear is the performer. The combination of the two has emerged as a safe elevator.

The speed limiter safety clamp system is an indispensable safety device for the elevator. When the elevator is over-speed, the operation is out of control, or the suspension device is broken, the speed limiter safety clamp device quickly stops the elevator car on the guide rail and remains stationary. Avoid casualties and equipment damage. 

The function of escalator brush

In addition to the escalator in the mall is the escalator. ~Do netizens know what they use the two brushes on the escalator? Curiosity drives me to understand. Here's my report.

Let's first take a look at the guesses of netizens:

Most netizens guess it's shoe-brushing. After all, it's brush.

Some netizens speculate that it is convenient to clean up the elevator and brush it down directly. Is it a little too long?

Okay, serious.

In fact, there are legal provisions to install brushes on escalators. "The accident risk can be reduced by installing anti-clip devices between the left and right sides of escalator and apron plate."

The anti-clip device here refers to the brush, which prevents the big guys from accidentally clipping their feet in the gap between the pedal and the edge, causing accidents.
