Grand Fuji Elevator Technical Specification & Engineering Guide

Project-Specific Parameters

Elevator configuration requires coordination of building structural constraints, traffic profiles, and electrical specifications. Standardized models cannot be applied universally across different destination markets.

Shaft Dimensions:

Clear hoistway width, depth, plumbness tolerance, and wall material.

Travel Characteristics:

Travel height, number of stops, floor-to-floor heights, and landing configurations.

Pit & Overhead:

Pit depth and overhead clearance conforming to rated speed and safety buffer requirements.

Power Supply:

Main voltage, frequency, phase balance, and line stability.

Integrated System Architecture

Subsystem	Core Assemblies	Functional Scope
Traction System	Permanent magnet synchronous motor (PMSM), traction sheave, wire ropes, counterweight	Generates and transfers lifting force
Drive & Control	VVVF closed-loop drive, main controller, signal processors	Regulates speed profile, leveling, and logic control
Door System	Permanent magnet synchronous door operator, car/landing doors, mechanical interlocks	Manages opening, closing, and interlock safety
Safety System	Overspeed governor, progressive safety gear, hydraulic/spring buffers	Provides mechanical protection under abnormal conditions
Guidance System	Machined/cold-drawn guide rails, roller/sliding guide shoes	Maintains vertical alignment of car and counterweight

Architectural & Cabin Finishes

Configuration of interior components matches building aesthetics, structural load limits, and accessibility codes.

Car Enclosure:

Car walls (hairline/mirror stainless steel, etched sheets, laminated panels), ceiling layouts, and floor recessing for PVC or stone finishes.

Fixtures & Signal Devices:

Car Operating Panel (COP), Hall Operating Panel (HOP), dot-matrix/LCD/TFT indicators, and voice synthesizers.

Accessibility Provisions:

Braille buttons, audio gongs, and landing heights conforming to EN 81-70 or ADA requirements.

Lighting & Ventilation:

Emergency lighting duration, LED fixtures, and forced/natural ventilation provisions.

Engineering & Technical Review Process

Parameter Audit:

Verify rated load, rated speed, car dimensions, and door opening against shaft layouts.

Interface Verification:

Review machine room or machine-room-less (MRL) integration, structural reaction forces, and beam load limits.

Electrical Matching:

Calculate starting current, running power, harmonic distortion, and emergency rescue device (ARD) integration.

Compliance Alignment:

Align specifications with EN 81, ASME A17.1, or destination jurisdiction codes.

Quality Control & Factory Inspection

Verification protocols ensure component traceability and functional performance before dispatch.

Material Traceability:

Mechanical testing and certification checks for guide rails, steel wire ropes, structural steel, and safety gear.

System Testing:

Pre-shipment bench testing of control cabinets, VVVF drives, and door operators under simulated electrical loads.

Document Deliverables:

Electrical schematics, general arrangement drawings, installation manuals, and factory test certificates provided prior to shipment.

FAQ

Q: Can car dimensions or door openings be customized for non-standard or existing shafts?

A: Yes. Cabin platforms, car frames, and door clear openings are engineered to match specific hoistway dimensions, subject to structural and safety clearance limits.

Q: How are local electrical grid differences handled for export orders?

A: Control cabinet transformers, VVVF drives, and motor windings are configured according to the exact voltage, frequency, and phase parameters specified for the destination market.

Q: What standards do the elevator control and safety systems comply with?

A: Systems are configured to comply with international standards such as EN 81 or ASME A17.1, as well as specific local jurisdiction codes confirmed during the technical review stage.

Q: What documentation is provided for local inspection and installation?

A: General arrangement drawings, electrical schematics, foundation load diagrams, installation manuals, and factory test certificates are supplied prior to shipment.
