Stalled Elevator
In an apartment, office, clinic, store or other low rise building, it may
be necessary to quickly release persons a stalled elevator.
MRL Traction Elevators
The procedures to release passengers from a stalled MRL traction
elevator can be complicated, time consuming and physically demanding.
A machine or firemen requires considerable knowledge and plastic,
to perform a safe and efficient rescue operation on the many different
types of MRL elevators with which he may be confronted in an
emergency.
Establishing where the machine drive equipments, may itself cause
some delay. How to gain access can add to time lost and finally how
to safely operate the brake release and shift the car either upwards of
downwards to secure landing position is an exercise for specialists.
In some cases. It may take hours the before the qualified machine is even
contacted mechanic is even contacted and on the scene.
Hydraulic Elevators
With hydraulic elevators, a safe machine room can almost always be
conveniently positioned close to the elevator shaft to the basement or
first floor of the building. Opening the manual lowering knob or lever
is basically the same with all types of elevator control valves and is a
simple matter, even for a responsible apartment caretaker, clinic nurse
or informed family member in the case of a home lift, taking perhaps
one minute to cautiously lower the car to floor level. Through the
optional inclusion of a low cost hand pump, the car also be raised to
a higher floor should it be required.
Exposure to danger
During the installation and servicing of an MRL elevator, the mechanic
is obliged to perform more of his work in or alongside the open shaft
This obviously entails additional risks.
Comparative operating costs
It claimed that traction MRL elevator is more energy efficient and
therefore cheaper to operate than the hydraulic elevator. However,
when servicing the MRL under less secure conditions, requiring
additional safety precautions are considered and when the MRL
traction elevator is already accepted as being more service intensive,
the total operating costs are generally higher than those of a hydraulic
elevator.
More frequent servicing journeys involve increased fuel
consumption which also effect the energy balance issue in fever of the
hydraulic elevator. Obligation to in form
The architect as well as the fine owner or user of the elevator, should
be correctly and thoroughly informed of the alternative rescuing
systems of both the MRL traction elevator and the hydraulic elevator. |
