LOAD DATA:-

(a) FOR FULL LOAD (165T) CAPACITY

(Ref. Clearance & Loading data for EOT Cranes; Doc. No. 5601-003-H143-PVM-W-039)

Span of the crane = m

Side and vertical clearance = m

Loading capacity of the crane = t

Weight of Crane = t

Weight of Trolly/Crab = t

Total no. of wheels on each side of the crane = Nos.

Static wheel load of loaded crane = t

Load Factor (All) =

(1) Max. Wheel load of loaded crane = t

(2) Lateral wheel load of loaded crane = t

Longitudinal wheel load of loaded = t

Total longitudinal crane load on beam = t

No. of nodes on which long. Force is applied = Nos.

(3) Long. Force on each node = t/node

(4) Self weight of the system has been calculated using "selfweight" command in Staad

(5) Weight of slab on beam 6.3 X 0.3 X 2.5 /2 = t/m

(6) Live Load over slab ( 0.5 t/m2 ) = t/m

(b) FOR CONSTRUCTION STAGE LOADING (10T)

Max. Object weight = t

Weight of Crane = t

Weight of Trolly/Crab = t

Total no. of wheels on each side of the crane = Nos.

Static wheel load of the unloaded crane = t

Max. Load on each wheel of the crane due to object wt. = t
