Commissioning of the hydraulic system was completed before in-
stalling the one-piece piston-head assembly. Wiring, then the installa-
tion of the drum segments and platform followed. Ground-floor ring
and first-floor landing equipment were then placed in position, with
platform fit out waiting until the surrounds of the lift and entrance were
complete.
Décor finishes were coordinated and completed before final com-
missioning of the entire lift system. A two-man team from Elevert
erected and commissioned the lift. The client’s in-house team of tech-
nicians and KONE staff provided assistance and support in moving the
heavy items and subassemblies through the palace entrance.
Maintenance
Access to the first-floor landing is gained by first removing the gate-
post assemblies, then lifting the floor pan. The inner workings of the lift
can be accessed via the machine room. An interlocked door between
the lift pit and machine room provides access to the hydraulic pistons,
telescopic machinery, dampers and guide rails. Also, an interlocked
floor trap in the platform floor allows access to a maintenance cell in
the head of the central tower, where the car-door drives, guide shoes,
terminal limits, floor switchgear and overrun buffers can be safely ac-
cessed. Maintenance control with inching buttons to move the lift is
provided within the maintenance cell.
