Have you ever confused that which type elevator is real better for your building? Traction type or Hydraulic type? Here’s our sightseeing of traction type elevators vs. Hydraulic type elevators.
Traction Type Elevators:
Traction type elevator use a counterweight to offset the weight of cabin and passengers, the cabin is raised and lowered by traction steel ropes or steel belts on a pully system. Through this type design, the traction machine no need to move as much weight, making it much more efficient than hydraulic systems.
Compared to hydraulic systems, traction elevators:
·Use less energy
·With high speed to serve high buildings (maximum 21m/s)
·Working more smoother
·Price is high
Traction elevators are the most common type of elevator.
Some are with geared machine,
some are gearless machine and both types are driven by
alternating current (AC) or direct current (DC) electrical motors.
In geared elevators,
there is a gearbox attached to the motor
that drives the wheel and moves the steel ropes.
This type elevator have a middle or even lower cost in terms of initial investment,
but following maintenaince and energy consumption will expensive.
In gearless traction elevators,
the sheave is attached directly to the end of the motor.
This type elevator have a high initial cost investment,
but they saving much energy in the following working days than geared elevators.
Hydraulic Type Elevators:
Unlike traction systems, hydraulic elevators don’t use hoisting machinery.
Instead, these elevators lift a cabin by using a fluid-driven piston
that is mounted inside of a cylinder.
Compared to traction elevators, hydraulic systems:
·lower cost for maintenaince
·better for transporting heavy goods
·lower material cost
·speed is very lower (4~6meters/min) not enough for high buildings
·large power needed
·machine room required
·voice is big ·not work smoothly
Above list of pros and cons for both types to give you a better
understanding of your options.
