Article 19 -Escalator Floor Plate (Machine Room Cover)

Escalator floor plate

In this article we intend to explain in detail about the standard safety requirements of escalator floor plate.

The platform surface on both landings that are installed before the comb plates are called “Escalator Floor Plate” which is used as escalator machine room cover. The floor plate according to the project installation environment and utilization is made of stainless steel or extruded aluminum and for more resistance is installed on the metal chassis. The standards guidelines for the escalator floor plate are as below:

  • The floor plate must be made of imperforated panels (without any gaps or spaces).
  • The floor plate must be opened only by keys or a suitable tool.
  • If the floor plate has two parts or more, one safety device must be provided for the 1st plate and other plates must be designed in a way that they cannot be opened or removed before the first plate is opened. If all of them can be opened in any order, we must install a safety device for each plate.
  • Due to the fact that the personnel can enter inside the machinery, the floor plate must be opened from the inside and no locks shall be considered.

Note: The floor plate is considered as an inspection cover and other inspection covers (e.g. exterior panels such us cladding and balustrade) must follow the conditions stated above. Please bear in mind that, the parts of interior panels of balustrade (such as decking panels) that are removable for maintenance purposes must not be considered as inspection covers.

Note: The maximum deflection of the comb plate and floor plate under a rated load of 5000 N/m2 must not be over 4 millimeters.
