Packaging & Shipping
For press fittings packing: we pack press fittings in polybag to prevent surface scratch, and then pack them inside brown export cartons.
For pipe packing: we pack the stainless steel pipes inside polybag, so that it can prevent surface scratch, and keep dirts away from the inside of the pipes.
If you have special requirement on packing, please tell us.

Elevator Modernization

Elevator modernization (or lift modernisation) is the process of upgrading the critical parts of the elevator in order for it to be able to handle new technology, have better performance, improve safety, and even give the aesthetics an up-to-date appeal

Most elevators are built to provide about 20 years of service, as long as service intervals specified and periodic maintenance/inspections by the manufacturer are followed. As the elevator ages and equipment become increasingly difficult to find or replace, along with code changes and deteriorating ride performance, a complete overhaul of the elevator may be suggested to the building owners.

A typical modernization consists of controller equipment, electrical wiring and buttons, position indicators and direction arrows, hoist machines and motors (including door operators), and sometimes door hanger tracks. Rarely are car slings, rails, or other heavy structures changed. The cost of an elevator modernization can range greatly depending on which type of equipment is to be installed.

Modernization can greatly improve operational reliability by replacing mechanical relays and contacts with solid-state electronics. Ride quality can be improved by replacing motor-generator-based drive designs with Variable-Voltage, Variable Frequency (VVVF) drives, providing near-seamless acceleration and deceleration. Passenger safety is also improved by updating systems and equipment to conform to current codes.

Benefits of elevator modernization

Modernization can greatly improve operational reliability by replacing mechanical relays and contacts with solid-state electronics. Ride quality can be improved by replacing motor-generator-based drive designs with Variable-Voltage, Variable Frequency (VVVF) drives, providing near-seamless acceleration and deceleration. Passenger safety is also improved by updating systems and equipment (such as double brake system, unintended car movement protection device on the brake system etc.) to conform to current codes.

With CEP traction elevator modernization, we use the existing elevator structure while upgrading the ride quality and reliability with state-of-the-art components. Upgrade to a CEP closed loop door operator or a sophisticated, energy saving VVVF inverter.

CEP traction elevator modernization can include:

• CEP Microprocessor Based Control System
• CEP Microprocessor Based Efficient Dispatch System
• Energy Efficient AC Drives or SCR Drives on Existing AC Gearless Machines
• Traction Machines (Geared / Gearless)
• Rope Brake System
• CEP Closed Loop Door Operating System
• Car & Hall Pushbutton Fixtures & Indicators
• Car & Counterweight Roller Guides
• Seismic Upgrades
• Security Upgrades
• Cab Interior Renovations or Cab Replacement

NOTE: Complete tear-out modernizations are available.
