Technical description
Drive terminal
This terminal is mostly placed at the bottom and is used for tensioning and passenger embarking.
It consists of a load bearing steel structure, a drive carrier and an hydraulic haul rope tensioning system, an engine with a gear box and anti-roll back device a drive bullwheel, guide sheave trains and leading sheaves.
The steel structure consists of two supporting columns anchored in separate concrete slabs, two A-type beams, two main beams with rails for the drive carriage, a front cross arm with sheave trains and a rear cross arm.
The drive carriage is a steel weldment at which the drive unit with the bullwheel is seated, and to which the beam with guide sheaves is bolted.
Hydraulic system - double-acting hydraulic motor - is placed between the rigid steel structure and the drive carriage. The hydraulic unit is seated on the drive carriage.
The drive bullwheel is seated on the gear box output shaft. It is a weldment with spoke bracing and a rubber lined groove. There is a safety rim at the bottom side of the wheel to prevent the rope slipping and also to stabilise carrier assembly.
As an option, the terminal can also be delivered as a disembarking terminal, and/or as a fixed one and placed at the top.
Return terminal
It is mostly fixed and placed at the top and serves for disembarking.
The steel structure consists of a supporting column, anchored into an independent concrete slab, compression braces and arms carrying sheave assemblies and platforms. At the top section of the supporting column, the return bullwheel is mounted by means of a screw flange joint. The return bullwheel is a weldment with spoke bracing and a rubber lined groove. There is a safety rim at the bottom side of the wheel to prevent the rope slipping and also to stabilise carrier assembly. Assemblies and the return bullwheel can be accessed by means of a ladder and service platforms with handrails.
As an option, the terminal can also be delivered as an embarking terminal, and/or as a tensioning one and placed at the bottom.
Support tower
The inclined "T-shape" support tower consists of a steel supporting column, anchored into an independent concrete slab, and a column head, to which sheave trains are attached. At the top section of the supporting column, service platforms are mounted. Platforms and sheave assemblies can be reached by a ladder.
Sheave trains
Sheave trains/assemblies have the role of guiding the line at the support tower. A sheave train consist of an appropriate number of rubber lined Ø200mm sheaves. Sheave trains on both lines of the lift are furnished with a safety device to detect rope coming off the wheels – a brittle bar.
