About Electric and Hydraulic Elevators

The electric elevator of all kinds are of the traction type, which incorporates multiple-hoist ropes along with counterweights. Hoisting machinery is placed at the top of the hoistway. In this circumstance, machinery's weight, along with the elevator lodgings, are to be carried by the building structure. 225 cm is the door opening height and the floor-to-floor height is 1.5 times door opening plus 15 cm. Car also opens on the two opposite ends where required. For applications that require low rise and slow speed, the hoisting machinery is placed in the basement adjacent to the hoistway. This machinery must be isolated, particularly in hotels.

(a) Gearless traction elevators - Designed for speed above 150 m/min.

(b) Geared traction elevators - Designed for slower speed passenger movement or for freight services. In applications of low speed, infrequency or requirement for minimum investment, the control of alternating-current rheostat type is suitable, in which the hoisting motor uses alternating current.

Leveling, or alignment in between the building and car floors, is not precise. Direct-current hoisting motor utilizes the variable-voltage control. Varied car speed is possible, along with smooth stops as well as quick acceleration and declaration. Every type of control is provided with automatic leveling. It also requires a motor generator set for each hoisting motor. It is not necessary to install this set in the machinery penthouse. A basement space is more preferable. The variable voltage control is more expensive than alternating current rheostat control.

(I) Hydraulic Elevator System:

A low-cost and low-maintenance-cost elevator system is the hydraulic elevator. The car moves at a low speed and the system is suitable for just low-rise buildings, generally about 6 serviced levels.

The elevator system does not have cables, brake drums, counter weights, MG sets, or costly control equipment. This system has few safety devices than the cable type elevator system. It results in the low initial system cost and reduces the maintenance requirements.

A hydraulic hoist or plunger is attached to the car floor structure, that moves it. The elevator machine is an oil pumping system, which pumps oil from the reservoir into the base of the plunger system and lifts the car. The same pump lowers the car by removing the oil from the plunger base. The guide rails in the shaft moves the car. The shaft pit has a buffer spring. The limit switches are also present. In case of oil leak, the car will descend slowly. It is the safest elevator system.

The maintenance of this elevator system is simple. The bigger maintenance problem is leveling the floor. It is possible that the elevator car stops slightly above or below the floor level. And if passengers are not careful when entering or leaving the elevator, there may be accidents. This floor leveling problem can occur because of some slight change in reservoir oil level.

The best system for leveling the floor is variable voltage traction elevator machine. It can be controlled within plus or minus 25 mm., with a hydraulic elevator, that is similar to a rheostat traction elevator. Leveling of floor with a variable voltage traction elevator machine can be controlled to within plus or minus 6 mm.

The energy operating cost of this elevator is high compared to cable elevators, as this elevator does not have counterweights and this requires large amount of energy. In low-rise buildings, this kind of elevator is used as service elevator.

One can avoid the superficial comparisons of power costs. As the electric traction elevator is counterweighted, only 40-50% of the load in both directions is imposed at the time of hoisting the motors. Full load on the apron and no load on the down run is carried by the hydraulic motor.

For the load given, the horsepower needed is greater for hydraulic than electric traction. The power consumption by both types of equipment is approximately similar. The initial cost for electric hydraulic is greater, but maintenance cost is lower compared to equivalent traction elevator.
