LEHY-Pro（菱云 Pro）

Product overview

What the LEHY-Pro (菱云 Pro) is

The LEHY-Pro, marketed in China as 菱云 Pro, is the flagship smart passenger elevator platform of Shanghai Mitsubishi Elevator Co., Ltd., a Sino-Japanese joint venture controlled and managed by the Chinese side. The brand positions it for high-specification commercial and residential work judged on ride quality, landing accuracy and control capability rather than price per unit. The rated range is 630 kg to 2,500 kg and 1.0 m/s to 3.0 m/s, with travel up to 150 m and up to 54 stops, which places it in the segment used for office towers, hotels, upscale residential cores and mixed-use podiums. The brand also states a levelling accuracy of ±5 mm and SIL3 safety functions for this platform.

Where it fits in a project

Typical applications are grade-A offices of moderate to tall height, hotels where guest lifts are part of the arrival experience, premium residential towers, serviced apartments, hospitals where a passenger group carries visitor traffic alongside dedicated bed lifts, and mixed-use podiums serving retail below offices. It is also used in modernisation, provided the existing shaft, overhead and pit accept the new arrangement.

In new build the platform enters when the core is being sized and the interior package defined, because finishes, door types and control options are selected with the shaft layout. In modernisation the shaft is surveyed, the machine room or its absence confirmed, and the configuration fitted to the measured space. Buyers raise four technical points before commercial ones. Landing accuracy comes first, since a few millimetres of error is visible at a stone landing and matters for trolleys, stretchers and accessibility. Second is the interface between lift control and the building's access or destination system. Third is the availability of spares and a service presence in the destination city. Fourth is whether finishes, lighting and handrails can be produced as a matched set.

What to check before you specify it

• Confirm the required load and speed inside the 630 kg to 2,500 kg and 1.0 m/s to 3.0 m/s envelope, and record both in the contract specification.
• Check travel and stop count against the platform limit of 150 m and 54 stops; beyond it the design changes platform.
• Ask which safety functions carry the SIL3 claim, and request the supporting assessment documentation rather than accepting the label.
• Agree how the ±5 mm levelling figure will be measured at commissioning, with instrument, load condition and acceptance record.
• Confirm the machine-room arrangement; machine-room and machine-room-less versions are not interchangeable in a fixed shaft.
• Check pit depth, overhead clearance and shaft plumb against the layout drawing, and confirm the builder's work scope in writing.
• Size door width and car depth for the real load: luggage, cleaning carts, stretchers or furniture, depending on building type.
• Define the destination or group control interface with turnstiles and access control, including behaviour when the link fails.
• Confirm firefighting lift requirements, lobby smoke control and the power supply arrangement with the local authority.
• Review the interior with physical samples: panel joints, lighting colour temperature and handrail fixing.
• Fix warranty scope, maintenance responsibility and the handover acceptance procedure in the contract.

Compliance and documentation

For CE marking markets the platform is assessed against EN 81-20 for the safety rules of construction and installation and EN 81-50 for design rules, calculations, examinations and tests of lift components; in China the governing standard is GB 7588. Where the destination has its own lift code, or requires local type approval or registration before use, that requirement sits on top and is confirmed by the buyer for the project. The SIL3 claim should be read with its assessment report: ratings apply to defined functions within a defined architecture, so the buyer should confirm the claim covers the functions the project relies on.

The document set normally supplied includes type examination certificates for the safety components and for the lift model where required, the certificate of conformity and declaration of conformity, factory test reports, the commissioning record, the packing list, and the installation and maintenance documentation with layout and wiring drawings and adjustment records. Third-party inspection can be arranged at the factory before packing or at destination. Where a notified body assessment is required, its scope is agreed before production, since it may add tests outside the standard factory programme.

Supply, inspection and shipping

ElevApex is a multi-brand supplier, not a manufacturer. Equipment is sourced from Chinese manufacturing partners, and for this platform the supplier is the Shanghai Mitsubishi organisation in China. Our work covers specification review against the destination code, order placement, engineering follow-up, inspection, export packing, certificates and shipping documents. Because projects often mix passenger, freight and escalator packages, orders can be consolidated into one shipment programme with one document set and one delivery schedule.

Pre-shipment inspection focuses on what cannot be corrected after arrival: car and landing panels against approved samples, controller configuration against approved drawings, safety component markings against their certificates, door operators and interlocks, and the levelling and ride test record. Third-party inspection can be arranged where an independent report is required. Packing separates the long from the delicate: rails in banded bundles, panels in plywood cases with a moisture barrier, machine and controller on pallets, small parts crated by assembly group. Shipping can be quoted EXW, FOB or CIF, and the loading plan is issued with the packing list so that rails and templates arrive before car finishes.

Frequently asked questions

What capacity and speed range does the LEHY-Pro cover?

630 kg to 2,500 kg and 1.0 m/s to 3.0 m/s, with travel up to 150 m and up to 54 stops. The rating for a project is selected from its traffic study and height.

What does the ±5 mm levelling figure mean in practice?

It is the brand’s stated landing accuracy for the platform. The project should define how it is measured and recorded at commissioning, since the method and load condition affect the result.

Is SIL3 a certification of the whole elevator?

It applies to defined safety functions within a defined architecture. The assessment documentation should be requested and checked against the functions the project depends on.

Can the platform be used for a modernisation?

Yes, subject to a shaft survey. Existing dimensions, overhead clearance and landing positions are measured first and the configuration is adapted to them.

How is the car interior specified?

From physical samples and a written finish schedule covering panels, ceiling, lighting, handrails and floor, approved before production rather than after delivery.
