超高层综合体电梯解决方案

Product overview

What the Hitachi ultra-high-rise complex elevator solution (超高层综合体电梯解决方案) is

This is not a single catalogue model but an engineered vertical transportation package for supertall mixed-use complexes: ultra-high-speed traction elevators, double-deck cars where the core geometry supports them, DFRS destination-floor reservation, and FI-700 group control supervising the zone. It is the part of the Hitachi range applied when the core, not the floor plate, sets the building's efficiency. Hitachi Elevator (China) Co., Ltd. was established in 1996 and describes itself as one of the three strongest companies in the Chinese industry by overall capability; it has built the world's tallest elevator test tower and the world's fastest elevator, with a maximum speed of 1,260 m/min. The specification quotes up to 1,260 m/min, approximately 21 m/s, as a technology ceiling, not a default selection.

Where it fits in a project

The solution belongs in buildings that stack several programmes: office floors above a retail podium, a hotel or serviced apartments above the office zone, an observation level, sometimes a transit connection at or below grade. The design problem is then not a single lift but a set of zones, each with its own handling capacity requirement, linked by sky lobbies and by shuttle groups running express between them. Double-deck cars only earn their cost where two adjacent floors are served at every stop, which in practice means a dedicated shuttle or a carefully planned office zone.

Planning starts at concept design, because shaft sizes, sky lobby floor area, the structural opening at each transfer level and machine room locations are all fixed by the traffic scheme. A traffic masterplan comes first, then tender documents, then the interface design with structure and MEP. New build is the normal case; in a retrofit the technology is applied to one group or to the upper zone rather than the whole core. Clients ask for handling capacity and interval that hold at the morning peak, an evacuation strategy the authority accepts, maintenance that needs no scaffolding at height, and a phased handover that lets lower floors open while upper floors are still fitting out.

What to check before you specify it

• Commission a traffic analysis before any car size is fixed; state the design peak, acceptable interval and population per floor.
• Confirm zoning and sky lobby levels first; shaft count and machine room location follow from them.
• Check that the building delivers two adjacent served floors at every double-deck stop, otherwise use single-deck cars.
• Treat the 1,260 m/min figure as the specification ceiling, not as a tender requirement.
• Confirm the firefighting and evacuation lift strategy with the local authority, including water protection.
• Ask for the wind-induced sway allowance and the resulting rail and rope compensation design.
• Review rope stretch, compensation and safety gear for the actual travel, not for a reference project.
• Agree structural loads at the machine room and rail brackets, including building shortening and creep.
• Confirm power quality, the regenerative option and earthing for a large concentrated motor load.
• Integrate DFRS with turnstiles and access control, and define what happens when the link fails.
• Define maintenance access, landing door locking and the working platform at the shaft top.
• Fix the commissioning programme, including who provides test weights and temporary power at height.

Compliance and documentation

For a supertall complex the compliance question is layered. The lift itself is assessed against EN 81-20 for construction and installation safety and EN 81-50 for design rules, calculations, examinations and tests of components where a CE marking market is the destination; in China the governing standard is GB 7588. Above that sit building-level requirements the lift must satisfy but does not define: firefighting lift provision, evacuation strategy, lobby smoke control, seismic design, and in some markets a separate acceptance procedure for equipment above a given height. Destination-country requirements are confirmed by the buyer, and the technical file is built against that confirmation rather than a general assumption.

Documents normally required: type examination certificates for the safety components and for the lift model where required, certificate of conformity and declaration of conformity, factory test reports including the at-speed and safety gear tests, the commissioning record, the packing list, and the operations and maintenance documentation. Third-party inspection can be arranged at the factory or at destination. The scope of the destination market's conformity assessment is agreed before the order is released, because it influences the test programme, not only the paperwork.

Supply, inspection and shipping

ElevApex is a multi-brand supplier and does not manufacture. The equipment for this solution is sourced from the Hitachi elevator organisation in China as a manufacturing partner, and our role is the commercial and documentary interface: reviewing the specification against the destination code, placing the order, following engineering releases, arranging inspection, consolidating export packing, and issuing certificates and shipping documents. Where a complex also needs escalators, moving walks or a lower-zone passenger package, several brands can be consolidated so that site receives one coordinated delivery programme.

Pre-shipment inspection concentrates on items that are hard to correct on site: machine and controller configuration against approved drawings, rope and safety gear certification, rail straightness and joint preparation, door assemblies, and the control software version. Packing is driven by length and weight: rails in long bundles with joint protection, machine and sheave assemblies on skids, controller cabinets in shock-mounted cases. Shipping can be quoted EXW, FOB or CIF, with the loading plan matched to the installation sequence, since rail installation at height sets the critical path.

Frequently asked questions

Is this a single elevator model or a project-specific solution?

It is a solution package. Equipment is selected per project from the Hitachi high-rise range, and the configuration follows from the traffic analysis, the zoning strategy and the building geometry.

What is the maximum speed quoted for this solution?

The specification quotes up to 1,260 m/min, approximately 21 m/s, which reflects the technology ceiling demonstrated in the manufacturer’s test tower. Project speeds are normally lower and follow from travel and traffic design.

When should the elevator consultant be appointed?

At concept design. Core dimensions, sky lobby levels and machine room positions are fixed early, and changes after the structural package is issued are costly.

Can double-deck cars be added later?

No. Double-deck operation requires the core to serve two adjacent floors at every stop, so it must be decided with the zoning strategy, before the shaft is built.

Which documents come with the shipment?

Type examination certificates, certificate of conformity and declaration of conformity, factory and commissioning test reports, the packing list, and the operations and maintenance documentation.
