Carga del Puente = 15.00 [tf]
Peso del Puente = 7.66 [tf] Peso del Hoist & Trolley = 2.07 [tf] Numero de Ruedas = 2.00 u Separacion de Ruedas = 3.00 [m]
ASCE 7: Maximun wheel load shall be the wheel load produced by the weight of the bridge plus the sum of the rated capacity and the weight of the trolley with the trolley positioned on it´s runway at the location where the resultin load effect is maximum. Carga Maxima de una Rueda = 10.45 [tf]
-> Sin Impacto

Vertical Impact
Elemento Monorail C ranes ( Powered) Cab Operated or Remotely Operated Bridge Cranes (Powered) Pendant Operated Bridge Cranes (Powered) Bridge Crane or Monorail cranes with Hand Gear Bridge, Trolley and Hoist.
ASCE 7: The lateral force on the crane runways beam with electrically power trolleys shall be calculated as 20% of the sum of the rated capacity of the crane and the weight of the hoist and trolley. The lateral force shall be assumed to act horizontaly at the tracction surface on a runway beam, in either direction perprndicular to the beam, and shall be distributed with due regard to the lateral stiffness of the runway beam and supporting structure.
Side Thrust = 20 %
Side Thrust = 3.41 [tf] Side Thrust = 5.46 [tf]
-> Servicio -> Mayorada
Longitudinal or Tractive Force
ASCE 7: The longitudinal force on a runway beam is calculated as 10% of the maximum wheel load of the crane. The longitudinal force shall be assumed to act horizontally at the traction surface of a runway beam in either direction parrallel to the beam. Tractive Force = 10 %
Side Thrust = 1.04 [tf] Side Thrust = 1.60 [tf]
-> Servicio (x wheel) -> Mayorada (x wheel)
Seismic Loads
ASCE 7: The empty weight of the component should be considered in the seismic mass. The Designer should carefully evaluate the location of the crane. Serviciability Criteria for Frames Supporting Cranes
1) Pendant operated cranes: Frame drift to be less than the height to the runway elevation over 100, based on 10yr winds or the crane lateral load on the bare frame.
2) Cab operated cranes: Frame drift to be less than the height to the runway elevation over 240 and less than 2in, based on 10yr wind or crane lateral loads. 3) All top running cranes: Relative inward movement of runways toward eachother to be less than 1/2in shortening of the runway to the runway dimention. This displacement would be due to vertical static loads. 4) All top running cranes: Relative outward movement of runways away from eachother to be not more than an increse of 1in in the dimention between crane runways.
