Car Elevators By Rachna Elevator & Conveyors

As the technology has gone far away from our imagination, we use the advanced techniques and methods with the technology to build a Car Elevator. The Car Elevators are used in the building or factories or the companies having a very large parking area with numbers of floors. It helps the car to lift up without driving, it is done to reduce the manpower which is the main objective of the fast-growing technology. Our company assures the defectless delivery of our product within the fixed frame of time.Standard Features:Digital Car PositionIndicator shows car position on all the floors of building.UP/DN Indicator shown the direction in which elevator moveVoltage Protection Upper and lower limit can be defined in every phase (220V) instead of consolidated 3 phase (440 V). this means maximum safety.Over & Under Load protection can be defined by ampere setting in individual phases for dot accuracy.Phase Preventer saves electrical parts when the single or two phase is out of supply.Phase Sequence Corrector automatically corrects the phase polarity when phases in the supply get changes.MFFS Stands for magnet floor and final (upper & lower limit) sensing. Replacement of limit switch (old and traditional technology). Though it senses without physical contact, life of the sensor is much more than the limit switch. Also accuracy of the same is unmatched.Buffer is provided in the pit to cure the cabin / material inside the cabin from the damage. It gives spring action to the free fall cabin. Selection of the buffer depends upon the cabin size, capacity, speed, travelling height of the elevator. Doors would be manual (collapsible) or Automatic.Maximum opening after the bunch in case of collapsible.Emergency Stop is provided in LOP to stop the cabin in case of any emergency or in case wrong command executed.Electrical Mechanical Door Lock features: - Door will not open during the lift movement.Door will open only on the floor where the cabin land / comes.Until all the gates were closed lift will not move.Over Speed Protection (comes with counter weight technology) can be accomplished by the Over Speed Governor which is a mechanical system which comes in action in case of rise in the travelling speed of the cabin due to any following reasons: - In case of brake failure.In case of motor failure.In case of gear box failure.And even in case of wire rope breaks.In any of the above mention accident, lift will never free fell, because mechanical break holds the Guide T and it will be stopped or slowly slide so that passenger or material will be safe in any circumstances.Car elevator can be installed with Counter Weight (GEARED)DrumHydraulicElevator Can Be Designed In Two Ways: -Elevator With Machine RoomElevator With Out Machine RoomElevator With Machine Room: Machine and control panel are fixed in a machine room which is constructed on top of the elevator shaft. In machine room we can use two different method:1. Drum Type2. Geared Traction.3. Permanent magnet motors (PM Motors).Elevator Without Machine Room / Machine Room Less / Mrl:  Machine and panel are fixed inside elevator shaft. Thus, save construction area and properly utilize the elevator shaft and space. MRL elevator is the result of technological evaluation.In the past few years the elevator manufacturers have crossed the barriers to accept the MRL product.  Many elevator manufacturers are now making their versions of the MRL, and have introduced various another type of machine room less applications. These days with the help of technical diversification geared machines are also used rather than gearless machines only. In MRL we use four methods:1. Drum Type.2. Geared Traction.3. Permanent magnet motors (PM Motors).4. Hydraulic Hole Type5. Hydraulic Hole Less TypeDrum Type are very economical in the category. In this system rope winds on the drum when cabin moves upward respectively rope gets unwind from the drum when cabin moves in the downward direction.Advantages:Most economic.Most easy to maintain.Very high capacity can be achieved.Can be installed in very less time.Geared Traction Elevators have been used in mid-rise, moderate-use buildings of up to 30 stories and typically operate at speeds of 0.5 m/sec to 2m/s. Geared traction elevators achieve their vertical motion from a Geared traction machine. In this machine AC electric motor is directly coupled to a worm which transmit the motion to the pulley (sheave) through worm gear. Sheave moves the wire rope in too &fro motion whos both the ends were tie with cabin and counter weight. As machine cum in action cabin start moving in either up or down direction as commanded, respectively counterweight moves in the opposite direction.Advantages:Moderate costPerfect solution for heavy load use.Easy to use and maintain.Permanent magnet motors (PM Motors) are widely use in Machine-room-less (MRL) elevator. They are basically used for high speed and high-rise buildings. The said machine breaks the speed barrier of 12mtr /sec. PM Machine is equipped with Permanent magnets to produce torque instead of gear box used in traditional traction machine. In this mechanism motor is directly couple to sheave, Sheave moves the wire rope in too &fro motion whos both the ends were tie with cabin and counter weight. As machine cum in action cabin start moving in either up or down direction as commanded, respectively counterweight moves in the opposite direction.Advantages:Can serve high rise.Easy to use and maintain.Creates more usable spaceUse less energy.Uses no oil It can operate at faster speed.Hydraulic Type: Hydraulic is the most robust technology in the elevator industry. It works in such a manner when oil push in the cylinder with the help of power pack piston moves up which rise the cabin. On another side by just releasing the wall oil from the cylinder come back in the power pack which lower down the cabin. Benefits of Hydraulic Elevator:No Over Head: Top of the shaft is closed just 2 feet of extra cabin height, which saves cost in construction.No Over Head Machine Required Security & Privacy: All the system is installed on initial level, so maintenance people wont move up.Less Running Cost: hydraulic system consumes energy only in moving up direction. So, comparing other systems running cost of the hydraulic is half.Cost Saving.Doesnt require heavy structure (column, beam, pillar) because machine is not installed on the top.No over Head & Machine required means huge cost saving in construction and exterior designing.Though panel install on initial level instead of top floor or in the machine room wiring expense for 3-phase and earthing connection will save.Even though hydraulic system is bit expensive comparing to Geared / Gearless / Drum overall cost would be lesser considering all above points.Hydraulic system is further classified in two categories:1. Hole Type2. Hole Less TypeHole Type: In this system a hole is drilled in the pit of the shaft where cylinder is to be install. Advantage of the system is: -Heavy load capacity.No load on the walls.Hole Less Type: In this system cylinder installs on the parallel of the wall with the help of the clamps. The system serves:More floors or height.More speed.Less capacityLess maintenance
