CUSTOM SIZES
Freight elevators are typically designed to meet specific building/operation needs. The above "standard" sizes are for general reference as a help with planning. Delaware Elevator can easily custom design your freight elevator to your specific size requirements. Contact your Delaware Elevator representative to discuss your specific requirements.
RAIL BRACKET FASTENING TO HOISTWAY WALLS
Hoistway wall supports for rail bracket fastening are required per the layout drawing locations. For block or masonary walls, wall inserts must be installed in the walls by OTHER than the elevator contractor. Masonary block must be filled with mortar around wall inserts to provide a solid permanent rail bracket support. Inserts are typically limited to capacities less than 10,000#. For capacities over 10,000#, a steel beam support structure may be required at each rail bracket location, as determined by a structural engineer per the rail forces as noted on the layout drawing.
For wood and metal stud hoistway walls, covered with sheetrock, a suitable header support (running front-to-back on each hoistway side wall) is required at each rail bracket location as per the rail force and location shown on the job specific layout drawing. A verticle beam structure may also be used, with a horizontal beam member located at each rail bracket location.
CLEAR INSIDE OF CAB
Width = Platform less 4"
Depth = Front Open Only
Single-section gate = Platform less 6½"
Two-section gate = Platform less 8½"
Depth = Front & Rear Open
Single-section gate = Platform less 8½"
DBG (Distance Between Guides) = Platform width plus 4"
OVERHEAD AND PIT DEPTH QUICK CALCULATION
Minimum overhead using single-section car gate = Cab height + (car gate height of 6'-0") + 6"
Minimum pit depth using vertical bi-parting freight doors = 1/2 door height + 6"
DOOR, CAB AND CAR GATE HEIGHTS
The freight car door height is the same height as the clear inside cab height (typically minimum of 8'-0"). The standard (typical) vertical car gate is 1-section 6'-0" high, sliding straight up to clear the cab height.
BI-PARTING FREIGHT DOOR FRAME REQUIREMENTS
Bi-parting freight doors require the door opening to have a steel channel frame with a bottom truckable sill angle. This frame is typically provided by, and installed by, the GC. The bi-parting door tracks are mounted to the flange of the steel channel frame on each side of the door opening
Class A: General Freight Loading
Where the load is distributed, the loading or unloading of the elevator is restricted to manual means or to a hand truck. The weight of any single piece of freight or of any single hand truck and its load is not more than 25% of the rated load (capacity) of the elevator. The rated capacity of this class of elevator shall be not less than 50 lb. per square ft. of inside net platform area.
Class B: Motor Vehicle Loading
With this class of loading, the elevator is used solely to carry automobile trucks or passenger automobiles up to the rated capacity of the elevator. The rated capacity of this class of elevator shall be not less than 30 lb. per square ft. of inside net platform area.
Class C1: Industrial Truck Loading
With this class of loading, an industrial truck is allowed for loading and unloading the elevator. The combined weight of the industrial truck plus the load cannot exceed the capacity of the elevator, whether in a static state during loading & unloading, or when the elevator travels with the industrial truck remaining on the elevator with the truck weight included as part of the load (capacity). The rated capacity of this class of elevator shall be not less than 50 lb. per square ft. of inside net platform area.
Class C2: Industrial Truck Loading
With this class of loading the industrial truck is typically used for loading and unloading only, of the full capacity of the elevator and is not normally carried by the elevator. The static load during loading and unloading is permitted to exceed the rated load (capacity). The maximum load including the industrial truck, on the platform during loading or unloading, shall not exceed 150% of the rated load (capacity). The rated capacity of this class of elevator shall be not less than 50 lb. per square ft. of inside net platform area. This class does not prohibit the carrying of the industrial truck on the elevator, provided that the total weight on the elevator does not exceed the rated load (capacity).
Class C3: Other Loading with Concentrations
With this class of loading the static load during loading and unloading, includng the weight of any loading equipment, does not exceed the rated load (capacity). Class C3 elevators are often designated to support single piece loads equal to the capacity of the elevator, however, this class does not prohibit the carrying of the industrial truck on the elevator, provided that the total weight on the elevator does not exceed the rated load (capacity). The rated capacity of this class of elevator shall be not less than 50 lb. per square ft. of inside net platform area.
