Upgrade – Repair – Replace?

Often when faced with old and/or worn or failed elevator (and by definition escalator) equipment the owner can consider several options, some confusing and depending on whom is pitching what product, the picture gets as clear as mud. A few observations that may help:
Upgrades:
We consider an upgrade to be an improvement to existing equipment.
Let's suppose that elevator door operation failures are noted and the cause is determined to be worn door operator components as reported from the elevator service vendor. And as the door operator is covered under most maintenance contracts, the service provider is required to maintain and fix it, but the vendor is not required to upgrade it. Now a door operator, unless outdated or uniquely manufactured can generally be rebuilt and brought to acceptable condition. However, this may not be the most beneficial course of action as given the relatively low cost of replacement with new operator that offers superior performance and operating features. In going the replacement route a discount in maintenance fees as a onetime or monthly deduction may be available from the service vendor. That discussion should take place with the service vendor before any decision is made as the savings may be considerable and will factor in that decision. Increased safety and a reduction in injury claims are to be taken into account bas well with a new door operator.
A common problem that escalator owners are faced with is handrail deterioration. There are a few options available for improved material type and other aesthetic options. Handrails commonly fail due to poor handrail drive and guide systems. If so, why not take the opportunity to use a higher grade replacement when the vendor replaces the component. As with door operators; the handrail drive system and its guide components are covered under most maintenance contracts, and it may be a small cost if any, to upgrade when replacing the handrail.
Repairs:
Repair work is fairly straightforward; it's broke, fix it. How it came to failure is the key. Was it due to abuse, vandalism, weather, accidental, or a wear item, failure of proper maintenance? That needs to be determined and the root cause rectified to prevent a reoccurrence. Much money has been spent only to have the same problem repeat itself. Once knowing the cause, you can look to the upgrade and replacement options.
Replacement/Modernization:
Replacements can be considered a repair with major component replacements such as with a modernization and due to the high cost usually involved, it must be approached with research and foresight. Why replace that worn escalator with all the related cost, when it may be possible to achieve performance, reliability, and aesthetics by doing some repairs and upgrades? As with most equipment, I've rarely, if ever, seen an elevator guide rail or escalator truss wear out. Why replace them when in most cases it's just not necessary? Modernizations are validated by the existing equipment not meeting the criteria presented today for performance. Also the aesthetic aspect is important to a building's success and tenants so it cannot be overlooked.
