POINTS SHOWING DIFFRENCE BEETWEEN HYDRAULIC AND TRACTION SYSTEM
SR. NO POINTS FOR CONSIDERATION
ARCHITECHTURAL
HYDRAULIC SYSTEM TRACTION SYSTEM
1 LOCATION OF MACHINE ROOM BASEMENT GROUND, OR ANY OTHER PLACE WITHIN 20 MTRS. OF THE LIFT . TOP OF THE BUILDING ABOVE THE LIFT
2 SIZE OF MACHINE ROOM LESS THAN 5 SQR. MTRS. ABOUNT 16 SQR. MTRS.
3 ELEVETION NO LIMITATION LIMITATION DUE TO MACHINE ROOM AT THE TOP OR HIGH COST TO CAMOUFLAGE THHE MACHINE ROOM.
4 VERTICLE LOAD NO VERTICLE LOAD ON THE BUILDING FULL VERTICLE LOAD DUE TO MACHINE ROOM ABOVE THE LIFT.
5 LIFT SHAFT SIZE. 10 TO 15 % SMALLER THAN TRACTION LIFT DUE TO NO COUNTER WEIGHT. 10 TO 15 % HIGHER THAN HYADRAULIC SYSTEM
6 CIVIL WORK COORDINATION NOT REQUIRED FOR MACHINE ROOM REQUIRED ONLY FOR 2 GUIDE RAILS GOOD POSSSIBILITY OF COMPRESSING ERECTION TIME REQUIRED FOR MACHINE ROOM REQUIRED FOR 4 GUIDE RAILS LESS POSSSIBILITY OF COMPRESSING ERECTION TIME
7 EARTH QUAKE SAFE AS ALL LOADS AT THE BOTTOM OF THE STRUCTURE NOT SAFE AS ALL LOADS ON THE TOP OF THE BUILDING STRUCTURE.
TECHNOLOGICAL
8 POWER FAILURE LIFT COMES DOWN TO NEAREST LEVEL WITH THE HELP OF A SMALL BATTERY STRENOUS AND CUMBERSME PROCESS TO MOVE THE LIFT IN ANY DIRECTION
9 POWER CONSUMPTION CONSUMES ALMOST 50 % OF THE POWER USUALLY CONSUMED BY TRACTION LIFT AS POWER IS NOT AT ALL CONSUMED WHEN LIFT IS TRAVELLING DOWNWARDS CONSUMES ALMOST 50 % MORE POWER USUALLY CONSUMED BY HYDARULIC LIFT.
10 SPEED AVAILABLE UP TO 1 MTR/SECOND.IN INDIA MUCH HIGHER SPEEDS ARE AVAILABLE
11 RIDING COMFORT SMOOTH RIDE, INHERENT PROPERTY OF HYDRAULIC TRANSMISSION. NOT SO SMOOTH . IN CASE OF SINGLE AND TWO SPPED LIFTS.
12 LEVELLING LEVELLING ACCURACY + OR - mm. IN ACCURATE LEVELLING IN SINGLE AND TWO SPEED DUE TO VARIATION IN BRAKE SLIP.
13 NOISE LEVEL SILENT DUE TO SPECIALLY DESIGNED MOTOR & PUMP SET IMMERSED IN OIL.. HIGH DUE TO MACHINE AND CHATTERIN OF CONTACTORS.
14 VIBRATION ALMOST PULSATION FREE PUMPING MACHINE VIBRATIONS TRANSMITTED THROUGH COLOUMNS & BEAMS.
15 BREAK DOWN LOW MODERATE
COST SAVINGS
16 POWER CABLE SHORTER CABLE AS MACHINE ROOM LOCATED ON LOWER LEVEL . LONGER CABLE AS MACHINE ROOM LOACTED ON TOP FLOOR.
17 CIVIL WORK SAVING AS NO CIVIL CONSTRUCTION IS REQUIRED AROUND THE SYSTEM , MACHINE ROOM IS SMALLER AND NO LIFT ROOM IS REQUIRED ON THE TOP OF TH SYSTEM. NO SUCH SAVING AS CIVIL CONSTRUCTION IS REQUIRED AROUND THE SYSTEM , MACHINE ROOM IS SMALLER AND LIFT ROOM IS REQUIRED ON THE TOP OF TH SYSTEM.
18 SALEABLE AREA ADDITIONAL AREA AVAILABLE DUE TO SMALLER LIFT SHAFT NO ADDITIONAL SALEABLE AREA AVAILABLE.
