“…Furthermore, Lonkwic and Gardynski in [9] put across a possible way of reducing oscillations, which are transmitted on a cabin from drive elements. Additionally, Herra and Kaczmarczyk in [5] determined a dumping coefficient, according to a type of passengers shoes.…”

The paper presents an analysis and assessment of recorded accelerations acting on Hybrid III dummy during emergency braking of a passenger lift. The dummy was equipped with a system of three-axis accelerometers. The type of progressive safety gear that has the shortest time of reaction and the shortest effective braking distance in its group, was chosen for tests. The tests were carried out on an emplacement, which simulated the movement of passenger lift. Tests of emergency braking were performed at variable load of a cabin corresponding to the mass of different passengers number. The cabin was dispelled by the gravity force using its free-fall. During the braking, the values of accelerations effected on individual parts of dummy, were measured. Based on them and using HIC and Nij indexes, the impact of temporary accelerations on passenger's health was determined.

“…These represent coupling or damping elements between the human body and the lift system (car). The effects of various damping characteristics of different types of shoes and the corresponding theoretical and experimental transmissibility have been studied and discussed in [6]. The dynamic response of the lift car can be influenced substantially by the characteristics of the passengers and their behaviour during the lift travel.…”

Ride quality of a Passenger Transportation System (PTS) is a measure of the comfort level experienced by passengers and is intimately associated with their subjective perception and sensitivity to motion and sound. This measure is affected by the noise and vibration of an operating system. On the other hand, ride quality is the measure of the PTS product quality. Ride quality of passenger transportation systems is critical for a PTS manufacturer to determine the subjective and objective quality of the system. This is especially important in high rise (high end) systems. The paper investigates the dynamic interactions that might occur between the PTS system components and their influence on ride quality.

“…As regards the reports on operation of lifts and hoisting installations in the literature world-wide, the area is now well studied. Besides, the available studies focus mainly on the user's comfort associated with acoustic emission [14], dynamic over-loading acting upon passengers during the ride [8,9,10,16] and investigations of the selected lift subassemblies performance [11,12,13,20].…”

The energy performance and operational characteristics of the passenger lift investigated in this study were based on energy consumption data registered throughout the normal duty cycle. An overview is provided of available methods employed to evaluate the energy uptake of passenger lifts, relying mostly on energy consumption measurements taken on a real object over an idealised reference duty cycle. Measurement data were used to determine the energy efficiency rating of the lift during the trip cycle and in the standby mode and the energy demand levels, which are then to be compared with measurement results obtained under the service conditions.
