Horizontal sliding doors, which sustain a high impact, may also suffer interlock misalignment, causing a shutdown Vertical sliding Peelle door interlocks are independent of the panels and located away from the opening and thus protected on the door-guides
Horizontal doors require a large amount of “return-space” for the panels Vertical sliding Peelle doors typically require thirteen inches, or three-hundred and thirty millimeters, of return space. This mean more usable “building-space” for the owner
Horizontal doors are subject to incidental impact during loading, when the entrance is not fully opened, causing a shutdown Vertical sliding Peelle doors permit loading only when the hoistway and car door entrance is fully open
Horizontal sliding doors have a mechanical coupling, between the car door and hoistway door which can separate during heavy duty loading, causing and elevator shutdown. Vertically sliding Peelle doors have independent operation with no mechanical coupling between the car door and hoistway door allowing for heavy duty loading conditions.
Horizontal sliding door sills are subject to damage, premature wear and debris which affect door performance Vertical sliding Peelle door trucking sills are designed specifically to the capacity and loading method of the elevator, and are flat to allow smooth loading. Door guides are located in the hoistway, running vertically,... read more →
Horizontal sliding doors are designed primarily for light duty applications. This can result in damage due to incidental impact from loading misuse and abuse. Vertical sliding Peelle doors are designed specifically to the capacity and loading method of the elevator, and are heavy duty and reinforced to accommodate hand truck,... read more →
How often have we seen a sign or rode a Freight Elevator that was a mislabeled Passenger (Service) elevator? What this creates is the perception to the riding public as well as within our own industry that elevators with horizontal sliding doors are appropriate for freight loading and transport. While... read more →
When considering the most efficient way to move freight/goods vertically during a buildings’ design phase, consideration is given to the elevator/lift usage, materials being transported, capacity and size of the potential elevator/lift, etc. Commercial/industrial applications utilize vertical sliding doors, particularly biparting, because they have proven advantages. The biparting door opens... read more →
