For this condition, maximum shear force- (ii) Maximum Bending Moment for the Girder: The maximum bending moment occurs when the centre of gravity of the loads and one wheel load are placed equidistant from the mid section of the span of the girder (Fig. 11.10) With this condition, Maximum bending moment = W/8l (2l – a) 2

As the crane load is moving load, at first, we must use the mechanical method to determine the most unfavorable wheel pressure position (bending moment and shear force) of the maximum internal force of the crane beam when calculate the internal force of the crane girder. Then the girder maximum bending moment and the corresponding shear force

II. DESIGN PROCESS OF CRANE. The design process of crane is carried out in both cally and in FEA analysis software. The crane is considered as a beam element. The analysis of the crane is considered as following cases. 1. Simply supported beam due to point load 2. Simply supported beam due to self – weight 3. Simply supported beam due to point

In the case of simply supported girders in which the maximum bending moment occurs at the centre the depth can be varied as shown in Fig. 10.4. This type of girders has become obsolete in modern times. In rigid frame constructions and continuous beams large moments occurs at the supports.

Step1: Calculate the maximum vertical Loads •The weight of the trolley (carriage) + Lifted Load (Rh) •The weight of the crane bridge (Rs) •The self weight of the crane girder & Rails (Rg) Note: The load to the crane girder will be maximum when trolley wheels are closest to the girder. 2011-2012

I notice from your PDF drawing that the crane girder is made up of 2-spans @ 8m each, continuous spans. With continuous crane girders it may be possible that your end-span connection bolt failures are due to tension forces when the crane is in the opposing/adjacent span, causing fatigue effects in the connection.

The following maximum values for the deflection of the crane girder must normally not be exceeded in order to avoid undesirable dynamic effects and to secure the function of the crane: Vertical deflection at midspan, due to maximum wheel reactions without duty features L/700

Note: The above minimum overhangs make allowance for end truck shear keys (see B above) on all overhangs used with 10” girders and Type BF end trucks or larger. Minimum overhang listed with types AL and A end trucks without interlocks are based on end truck width.

CRANE GIRDER Crane Girder is an assembly of steel plates, angle and rails. Steel plates forms the flange and web of girder while the angle forms the stiffening part of the web plate. Steel plates are also used as diaphragms of the girder. Together all of these make up a box section. The girder box section is shown below: Figure-2 Crane Girder

Sep 26, 2020 · Bridge and double girder cranes are far more flexible and allow 3-dimensional hook movement. In these installations, the crab can move across the crane girder to cover the breadth of the space. In addition, the crane girder assembly can move along the length of the space covering a far wider area than a monorail.

determined, AASHTO type 4 girder was chosen as the girder used in this design. In Chapter 5, three separate tendon profile and shear reinforcement design of the prestressed concrete girders were presented to satisfy each of the design standards. Similarly, the reinforced concrete deck is also designed in accordance with each code in
