A lift is a system permanently installed that serves for vertical transport of persons or goods . Lift installation team usually has 3 or 4 members: installation mechanic,electrician,the person in charge of installation who consults with; cranemen, scaffolders, carpenters and masons.
The team requires to get familiar with:
- Construction layout drawing of the building
- Structural diagram of the elevator hoistway
- Layout drawing of the elevator hoistway
- Drawings of related embedded parts and preformed holes
- Layout plan of the machine room.
Lift Installation processes
- Scaffolding
Scaffolding is a required item of preparation for lift installation. The quality of scaffolding has a major influence on the safety of the installation personnel and the progress of lift installation. - Fabricating template holders
Materials used for fabricating template holders include wood and profiled steel.Profiled steel is usually used for high-rise elevators. Wood is the most frequently used material for the time being.
- Erecting template holders
Template holders are usually fixed in the hoist way 500mm below the floor of the machine room. If there is no machine room or there is only a small machine room, the template holders are fixed in the hoistway 250mm below the top plate of the hoistway. - Installation of rail supports
Check the ring beams or embedded steel plates of the hoistway
Check the positions and exterior dimensions of the ring beams of the hoistway and embedded steel plates of the brackets according to the Vertical Elevator Hoistway Drawing.
- Installation of landing doors
- Installation of hoisting machine
- Installation of buffers
A hydraulic buffer is usually used. The buffers are usually selected according to the rated speed. - Installation of car frame and safety gears
The car is usually assembled on the top terminal landing because the top terminal landing is closest to the machine room and thus convenient for lifting the parts and checking dimensions of the machine room. - Installation of hoisting ropes
When the car is in the leveling position of the highest floor (the raised height of the car shall be taken into consideration), the counterweight is at the bottom floor, and the distance from its counterweight ram to the buffer in the pit is S, use a 2.5mm2 electric wire to measure the working length needed for the steel wire rope and allow for 500mm margin at each end. - Installation of car
- Installation of door operator
- Installation of speed governor
- Installation of infrared multi-beam screen
This device will be assembled if the user chooses this option. - Installation of control cabinet
- Installation of cable system
The cable system mainly comprises: flat-shaped hoistway trailing cables,
round-shaped prefabricated hoistway cables, and other branch cables - Installation of signal system
The signal system mainly involves:
1. Installation of terminal landing switches, travel limit switches, and final limit cams
2. Installation of magnetic screens and magnetic switches - Installation and connection of rotary encoder:
The rotary encoder is an important device for detecting speed feedback in the elevator
control system. The quality of its installation has a direct influence on the system performance. - Wiring and earthing
Volkslift East Africa’s engineers, technicians, and project managers possess a high level of education, resources and technical support for lift installation. (more…)
Eco-friendly elevators?
The first question probably running through your mind is what is an Eco-friendly elevators. Some people refer to them as green elevators. One thing to keep in mind is that energy consumption is key. For Eco-friendly elevators the processes we apply, the machines one needs and the type of technologies that you use are used as determinants when integrating the elevators. Other aspects we consider is the lighting, the type of control panels and the HVAC systems plus flooring and painting. All this contribute to an elevator being Eco-friendly thus becoming very key on its outlook and general operations.
We use inventions such as Machine room less Technology which was initially introduced in the mid-1900s. Miniature versions of the technology have made it convenient to run an elevator incorporating a gear less traction design. Our elevators look to save up to 50% of energy reduction than earlier inventions. Some make use of already used energy by recovering the used energy and putting it back to the electrical system. Looking at the large scale of things, you’d comfortably save a lot of energy in a month alone. They are known as regenerative drive system.
How they work
We use current technologies that make use of double deck elevators. They are called group control systems, mostly used in buildings with high traffic. It moves traffic to one lift at a time and minimize on the number of stops to be made. You’ll find one lift only makes stops to even numbered floors or on odd numbered floors. This makes it possible for us to help ease flow especially in urban areas with high traffic.
There’s also the use of in-cab sensors that allow elevators to go into idle mode. The same way phones would go to sleep mode when they’re not being used. Therefore, when the lights go out, the music stops, video screens are off, the ventilation system slows much of electricity. Even the energy consumption is reduced thus helping cut on costs incurred as well.
Lastly, we have the use of destination dispatch software. It takes elevator stops in batches and then makes all the necessary stops in one trip. Other elevators would make every person going to one floor wait for the next trip. This makes a passenger take longer to get to where they’re going.
The advantage of using eco-friendly elevators is that your buildings will use less water, energy and other materials especially when looking at the long term aspect. In order to meet your needs, we are enhancing our products with the capabilities that will decrease large energy consumption as well as help conserve the environment.
They help improve the building’s efficiency as well as property value. Systems with destination control software would help avail transportation much faster and much more efficient travelling capabilities. This would let the building owners to welcome more tenants with traffic needs.
- Does your elevator or escalator equipment break down frequently?
- Has the County Inspector identified that the equipment is not up to code?
- Do you get complaints about old décor, or are you looking to update your décor?
- Are you interested in “Going Green”?
- Do you need an economic solution to the long-term use of your equipment?
If the answer to any of the above questions is yes then your elevator modernization is the answer to your problems and we are the people you need to turn to. Volkslift East Africa offers the following Service Difference in comparison to other lift companies:
- We provide a wide variety of choices in technology and decor. This allows the customers to have a choice in their elevator purchases.
- More so, Incorporation of Eco-sensitive finishing material options to meet “Green” or “LEED” requirements. LEED means (Leadership in Energy and Environmental Design).
- Lastly, installation of systems that are developed with the latest computer and micro processing technology.
No matter what your vertical mobility needs are, we can accommodate your business needs. For elevator lifts and escalators orders and inquiries, send us an email on info@volksliftea.co.ke or call us today on 0716757222
