3 Definitions
For the purposes of this Standard, terms and definitions specified in GB/T 7024 the following apply:
3.1 Traction drive lift
A lift whose lifting ropes are driven by friction in the grooves of the driving sheave of the machine.
3.2 Positive drive lift
A lift suspended by chains or ropes driven by means other than friction.
3.3 Non-commercial vehicle lift
The lift suitable to carry private vehicle in its car.
3.4 Pulley room
A room not containing the machine, in which pulleys are located, and in which the overspeed governor and the electrical equipment can also be housed.
3.5 Available car area
Area of the car measured at a height of 1 m above floor level, disregarding handrails, which is available for passengers or goods during operation of the lift.
3.6 Re-leveling
An operation, after the lift has stopped, to permit the stopping position to be corrected during loading or unloading, if necessary by successive movements (automatic or inching).
3.7 Minimum breaking load of a rope
The product of the square of the nominal diameter of the rope (in square millimeters, mm2) and the nominal tensile strength of the wires (in newtons per square millimeter, N/mm2) and a coefficient appropriate to the type of rope construction.
3.8 Safety rope
An auxiliary rope attached to the car, the counterweight or balancing weight for the purpose of tripping a safety gear in case of suspension failure.
3.9 User
Person making use of the services of a lift installation.
3.10 Passenger
Any person transported by a lift in the car.
3.11 Authorized and instructed user
The person authorized by the equipment principal and instructed how to use lifts.
Without other provisions, if the lift principal has handed the lift instruction manual to the authorized and instructed users and one of the following two conditions are satisfied, the user can use the lift:
a) Only the authorized and instructed users have the keys, and insert the key into the lock in or out of the car, the lift can be started;
b) If the lift is installed in the public unaccessable places, then the lift is not locked up, the lift principal will send one or more persons to take charge.
3.12 Lift machine
The unit including the motor which drives and stops the lift.
3.13 Balancing weight
Mass which saves energy by balancing all or part of the mass of the car.
3.14 Electric safety chain
The total of the electric safety devices connected in series.
3.15 Inspection trap
Outward-open trap installed in the shaft for the purpose of inspection and overhaul.
3.16 Emergency door to the well
When the distance between consecutive landing doorsills exceeds 11 m, a door will be built on the interim shaft wall for rescuing the passengers.
3.17 Laminated glass
An assembly of 2 or more glass layers, each of which is bonded together using a plastic film.
