The powered door panel or panels forming the entrance to the elevator cabin, driven by a door operator and mechanically coupled to the landing doors via a door coupler when the car is at a landing.
Full Definition
Cabin doors are fabricated from cold-rolled steel (typically 1.5–2.0 mm, galvanised or powder-coated) or stainless steel (1.2–1.5 mm, grades 304/316). Panel width and height are selected to match the clear opening width required by EN 81-20 (minimum 700 mm for most passenger lifts; 800 mm for accessible lifts per EN 81-70) and the clear height (minimum 2000 mm). Door panels hang from a top track via roller hangers and are guided at the bottom by sill gibs running in the door sill channel. The cabin door is driven by the door operator motor through a linkage or direct-drive belt system. An electromechanical door contact (EN 81-20 Section 7.7) must confirm the cabin door is fully closed before the elevator can move. Material finishes include powder coat, brushed stainless, mirror stainless, and glass insert panels with steel frames. Fire-rated door assemblies (EI60/EI90) are required in firefighter's lift shafts.
