Comparison between Hydraulic and Traction Elevator |
|
Sr. No. |
Description |
Traction Elevator |
Hydraulic Elevator |
01 |
Location Machine Shop |
Top of building above the lift shaft |
Basement, ground or any convenient place e.g. under the stairs but within 20 sq. mtrs (abt 50 sq. ft.)
|
02 |
Vertical load |
Full vertical load due to machine room above lift shaft. |
No vertical load on building structure. |
03 |
Old building |
Invariably independent structure required for installation. |
When building cannot take vertical load, often Hydraulic lift is only choice. |
04 |
Lift shaft size |
10% to 15% higher than Hydraulic lift. |
10% to 15% smaller than traction lift |
05 |
Civil work co-ordination |
Required for machine room installation. Required for 4 guide rails.? |
Not required for machine room installation. Required only for 2 guide rails. |
06 |
Earthquake |
Not safe as all loads at the top |
Safe as all loads at the bottom. |
07 |
Power failure |
Strenuous and cumbersome process to move the lift in any direction. Alternatively, alternate power source required which is very expensive. |
Lift comes down to nearest level with the help of small battery. It can be
brought down to ground floor by pressing the button on the valve block. |
08 |
Maintenance |
Moderate |
Quick and Simple |
09 |
Riding comfort |
Not so smooth. In case of single & two speed lifts. |
Smooth ride. Inherent property Hydraulic transmission |
10 |
Leveling |
Inaccurate leveling in single & two speed due to variation in brake slip. |
Leveling accuracy +10 mm. |
11 |
Noise level |
High due to machine and chattering of contractors |
Silent due to specially designed motor & pump immersed in oil. |
12 |
Vibration |
Machine vibration transmitted though columns & beams |
Almost pulsation free pumping. |
13 |
Breakdown frequency |
Moderate |
Low |
14 |
Saleable area |
No additional saleable area available |
Additional area available due to smaller lift shaft. |
15 |
Power cable |
Longer cable as machine room located on top floor |
Shorter cable as machine room located on lower level |

Gantry Cranes provide economical material handling in areas where an overhead crane system is not available or practical. Their safety and efficiency make them a frequent choice for production, installation and maintenance application.
Types of gantry cranes are available in either fixed or adjustable height models. Both types can be disassembled into three components of greater portability. |
