Technical condition:
according to the documentation of 70004, 70003 list cable crane (Kocks cranes of TCL) and cable list 70008 crane (crane of crane higher TCO of TCL 3 m) then the number of meters of cables is the same: capture frame
A9550 TM1-x 11 X 12-DCF1 YSLTOEU-JN 42 x
2.5 10 m = 95. D/DCF1 1.3
A9551 TM1-XP1 SP1 – X 11 YSLTOEU-JN 52m 2.5 x 42 = D
DCF1 1.3/95.
A 10 m long A9550 fiber go from cabin in the car long A9551 52m fibers and turtles from the wheelbarrow down the frame capture.
for crane KE electrical cable length frames taken from the cabin down the frame shooting is 67m
after the actual measuring in crane 2 TCO, the cable length from the wheelbarrow down the frame shooting is about 47m (by cutting the cablethe 2 connections, etc.).
With a length of cable of crane 2 TCO (higher crane TCL 3 m) when do rows at the bottom decks at the water down the power cable is not enough, have to wait for the water to do continue. When done in a deep tunnel, the amount of the remaining cable in cable hopper few, if any wind to capture frames or pendulum shall be definitive and cable stretch and crane driver must drive slowly, carefully, affect the speed to do customers.
-With status on recommendations the following solution 2:
GP1: proposal to provide new cable connected from the wheelbarrow down the frame taken with a length of at least 60 m (total length from the cabin down the frame shooting is 70 m) based on the number of cable crane's meter KE be 67m (operation) plus 3 m height crane's TCO.
GP2: Relocate the outlet on the wheelbarrow to the cluster of motor car corner turtle c. To relocate the outlet increases are adding about 2 m cable down the temporary capture frame ensures bilge shop cranes, crane driver, however, still have to drive slowly, carefully avoiding the cable tension and when the cluster repair motor trouble C corner wheelbarrow.
-Suggest rethink the length of all the cranes being locked to avoid missing cables, not only for the power cable the frame capture (because the new crane higher and longer).
I review what mistakes correction helps children. (I attach 2 cable file list, excel file is of the TCO)
thank you!
