Elevators - Gearless and Geared

Elevators Gearless Machines Vs Elevator Geared Machines

Elevator Geared Machine with Machine Room

Geared machines have gearbox and routine oiling is required.
Risk of oil contamination and spill is high.
High Energy consumption.
Limited elevator floor travel.
For high rise towers elevator vibrations are possible.
Low efficiency as compared to Gearless Machine.
Installation  and service costs are higher.
Elevator machine room space required is more as machines are bigger in size.
Harmonics noise is more.
Power consumption is high due to more torque required and efficiency is lower.
Due to high maintenance, doesn't have  a long life.
Electromagnetic brakes are used.
Brake adjustment is less convenient.
Proper routine maintenance required due to more wear and tear.
Periodic oiling and lubrication required.

Elevator Gearless Machine With Machine Room

Gearless machines do not have a gearbox hence, they do not require any type of oiling.
No risk of oil contamination or spillage to the ground.
Less energy consumption, nearly 50% saving in energy costs.
Nearly unlimited elevator floor travel without vibration.
High efficiency as compared to geared machine.
Easy to install and service cost is lower.
Elevator machine room space required is less because machines are small & compact.
Harmonics noise is totally eliminated.
Minimum power consumption and maximum torque & high efficiency.
Maintenance is less and longer life span.
Disc break technology for instant stop.
Jerkless elevator operation with ride comfort and ride quality.
Elevator brake adjustment is more convenient & noise free.
Frequent elevator stops & start operation will not affect the motor.
Hence negligible wear and tear and lower maintenance is required.
Oiling & Lubrication is totally eliminated.

Advantages Of Gear-less Machines Used In Elevators

Features of Gear-less Machines used in Elevators:

A Gear-less Machine adopts a disc brake, which has more advantages than the traditional drum brake. The rate of malfunction is lower, which means it’s safer, and no circumstances of brake getting stuck. The noise of opening and closing brake is lower. The adjustment of clearance between brake force and brake disk is more labour-saving and convenient. Adjustment is hardly ever needed in daily running.

Brake absorption current is one half lower than that of a drum brake. A gear-less machine is built with equipment of pressure decline after brake starts working, which is no longer needed in the control box. The starting torque of a Gear-less Machine is strong, and the current of starting operation is smaller than the similar products. It can match lower power transducer, and save cost. According to strong starting power and low current, the physical volume of a Gear-less Machine is smaller than the similar kind of products.

According to the special design of a Gear-less Machine coil, the low speed starting and braking pulsation is less than similar products. A Gear-less machine does not have a gearbox, thus they do not require any type of oiling. Gear-less machines are considered superior to Geared Machines because they are more efficient and quieter in operation, requires less maintenance and has longer life. Due to the AC drive control, brake wear is virtually non-existent. It saves about 50% of energy consumption,  and thus it consumes less current. Also frequent start-stop motion of the elevator will not cause any negative impact on this system. Gear-less Machines are used where the rise is more and very smooth & high speed operation is desired.

Summing up a Gear-less Machine has the following advantages:
1.No risk of oil contamination.
2.Nearly unlimited floor travel.
3.Has greater efficiency.
4.Has superior speed and performance.
5.Smooth & jerk free ride, high reliability, less noise and has a longer life span.
6.Safer ride when compared to a geared machine.
7.Saves on energy, actual consumption is about 50% that of geared machines.

Elevator Sales

China Peaks 600,000 Elevator Units

Last year China sold an amazing 600,000 elevator units, 65% of the world's gross elevator sales. But, elevator industry experts say that will probably be the last time China sees sales figures like that. The current year's expectations are a modest 500,000 elevator units. Sales figures are expected to fall further in coming years to stabilise at much lower levels.

China is battling a construction slowdown as it faces a surplus of urban apartments as well as a slowdown of it's people moving to urban spaces. The growth of the Chinese construction industry during the past decade has left construction industry experts breathless by it's sheer pace.

The Indian elevator industry in turn had been posting a modest 13.5% growth since 2001. It is expected to surpass growth figures of 20% by 2018.

Elevator Industry In India

Elevators In India - An Overview

The overall documented international market figures for elevators was approximately 7,50,000 to 8,00,000 units. China easily tops this list with approx. 4,87,500 units, followed by India with 52,600 units and rest belonging to smaller markets.

The Indian elevator industry according to industry experts is projected at exceeding 1,00,000 units by the year 2018. The nation's top city markets for elevators are Mumbai and National Capital Region (NCR) followed by Pune, Chennai, Bangalore, Ahmedabad, Kolkata, Hyderabad and Surat. The industry's growth rate since 2001 is a healthy 13.5% per annum and likely to exceed 20% per annum by the year 2018.

India's top 30 cities account for over 70% of the elevator market in India. But that scenario is likely to change given the following parameters.

# By 2030, near 50% of the nation's population is expected to live in the urban areas, as against the current 31%.
# The number of high-rise buildings is rapidly growing in India irrespective of the class of cities, whether Tier II / Tier III etc.
# Over the last decade, approx. 2,700 new cities have been added to the urban areas list, taking the total number of cities in India to over 7,900.

Passenger elevators form around 85% of the total elevator market in India. But that figure too is likely to under some change. An increase in wealth, changing lifestyles and an increasing demand for premium villas and apartments is likely to jack up demand for residential elevators and home lifts. In the next five years, elevators could become a standard fixture for every apartment.

Elevator companies in India are poised to face the jump in demand for elevators.
