A pit is a term used to describe the recess in the lowest floor that the lift is serving. In order to provide level access onto the lift platform, it will be necessary to create a pit deep enough to accept the thickness of the lift platform. Platform lifts typically require a pit depth of 50mm – 85mm. Heavy Duty Platform Lifts & Low Pit Cabin Lifts typically require a pit depth of 100mm – 200mm. In contrast, a full blown Passenger Lift will require a pit depth of 1200mm or more. If it is not possible to provide a pit, then a fixed ramp option is often available. The height of the ramp will be the same as the required pit depth (in other words, if the pit would have been 50mm deep, then the ramp will be 50mm high).
