Recommendation 1. Installation of an oil recovery ring on the jackhead, as required by ANSI A17.1, Rule 1302.3 h ( Safety Code for Elevators and Escalators ) would significantly reduce the hazard risk associated with this condition. Frequent inspection of the neoprene seal for damage and routine engineering evaluation of clearance tolerance between the plunger and jackhead will also ensure system integrity and reduce risk. A controlled RAC of 2E (critical/improbable) could be assigned to this condition once the recommended controls are implemented.

These spaces are of primary importance to the safe and reliable operation of elevators. In the United States, all ductwork or piping in these rooms must be for the sole purpose of serving equipment in these rooms unless the designer obtains permission from the anthorities in charge of administering American National Standards Institute/American Society of Mechanical Engineers (ANSI/ASME) Standard 17.1, Safety Code for Elevators and Escalators. If architectural or structural features tend to cause an infringement of this rule, the duct or pipe must be enclosed in an approved manner. 

The potential of interface elements in elevators and escalators is vital. They play a very important role in bringing about cPose relations between various mechanical components in static and dynamic conditions. Examples are cited in lifts/elevators escalators and travelators where components rolling over each others or some static and others moving over the static ones. Various contact or gap elements have been explained in various finite-element packages Some of them are cited below ...
