Ornate elevator service Home Elevators Company in karnataka and andhra pradesh which is founded in 2016 . Make a great success in the history. We are providing Home Lifts, Residential Elevators, Stair Lifts, Platform Lifts, Cog Belt Home Elevators, Gearless Residential Lifts and Hydraulic Home Elevators for Small House, Villas, Bungalows, Buildings and Luxury Homes to all over India.
In a short span of time, Ornate Elevators have established itself as the #1 Home Elevators Company in India. Our residential elevators are manufactured by OrnateElevators Access in a special facility in Pisa, Italy & follow European Standards of Home Lifts. These home lifts can be installed at under construction houses as well as existing homes, as our home elevators are tailor-made, pit less, they require no shaft & no machine room. Contrary to traditional & commercial lifts in India, our lifts are strictly manufactured for residential purpose for Duplexes, Bungalows, residential buildings & Villas. Post-installation our home elevators are certified by TUV, a third party organization which measures product’s safety as per European Standards & guarantees you Peace of Mind.
Hydraulic elevators are elevators which are powered by a piston that travels inside a cylinder. An electric motor pumps hydraulic oil into the cylinder to move the piston. The piston smoothly lifts the elevator cab. Electrical valves control the release of the oil for a gentle descent.
Hydraulic elevators are used extensively in buildings up to five or six stories high. Sometimes, but rarely, up to 8 stories high. These elevators, which can operate at speeds up to 61 meters (200 ft) per minute, do not use the large overhead hoisting machinery the way geared and gearless traction systems do.
Gearless traction electric elevator first invented by Otis in 1913, first installed in Woolworth Building in New York City. This type of drive system could be employed in buildings of any height and operated at much higher speeds than steam-powered elevators. This design has proven so durable that even now, when a building is modernized—while the elevator control system is replaced with the most up-to-date electronics—it is rarely necessary to replace a well-maintained gearless machine. These elevators typically operate at speeds greater than 500 feet per minute (or 2.5m/s).
In a gearless traction machine, five to eight lengths of wire cable, known as hoisting ropes (or wire ropes), are attached to the top of the elevator and wrapped around the drive sheave in special grooves. The other ends of the cables are attached to a counterweight that moves up and down in the hoistway on its own guiderails. The combined weight of the elevator car and the counterweight presses the cables into the grooves on the drive sheave, providing the necessary traction as the sheave turns.
Geared traction machines are driven by AC or DC electric motors. As the name implies, the electric motor in this design drives a worm-and-gear-type reduction unit, which turns the hoisting sheave. While the lift rates are slower than in a typical gearless elevator, the gear reduction offers the advantage of requiring a less powerful motor to turn the sheave. These elevators typically operate at speeds from 38 to 152 meters (125-500 ft) per minute and carry loads of up to 13,600 kilograms (30,000 lb). An electrically controlled brake between the motor and the reduction unit stops the elevator, holding the car at the desired floor level.
Contemporary cheaper installations, such as those in residential buildings and low-traffic commercial applications generally used a single or two speed AC hoist machine (abbreviation is AC/(speed number)). The widespread availability of lower-cost solid state AC drives has allowed infinitely variable speed AC motors to be used universally (for ACVV/AC – VVVF), bringing with it the advantages of the older motor-generator based systems, without the penalties in terms of efficiency and complexity. The older MG-based installations are gradually being replaced in older buildings due to their poor energy efficiency.
