The Crane 1000 Series is the solution when your budget-conscious project calls for the look, function, traffic flow advantage, and energy savings of a revolving door. Fabricated with rigid aluminum construction, the 1000 Series offers choices that allow you to match the doors to your entrance requirements.
The 100:1 gear manual speed control and bookfold mechanism are the same as those used on all Crane revolving doors. The primary material is .125 thickness aluminum construction and iron workers and experienced craftsmen in Crane's Chicago facility complete all door construction.Speed control
The Crane speed control is a free-wheeling, precision-machined, cast-steel geartrain mounted in the ceiling canopy or floor. It engages the brake automatically as speed approaches a set r.p.m. The brake shoes can be easily adjusted or replaced.Bookfold mechanism
The Crane bookfold mechanism meets all state and federal requirements for providing emergency egress. The pressure to engage the bookfold mechanism is adjustable to meet local conditions - for example, stack conditions, negative pressure, and wind conditions.
