Friday, May 23, 2025, 13:12, chad fisher, Manipulator Maintenance, Repair, , , SHC West manipulator tong cable replacement
|
Broken tong cable on West manipulator (serial #8106) replaced.
Wrist joint with broken cable was replaced with the spare wrist joint, pre-strung with a new tong cable. Tong cable is routed the "new" way (as described in April 3, 2024 wrist replacement), over the interior spacer.
Both East and West manipulators now have wrists with cables routed in this fashion which, in theory should result in longer cable life.
Tong cable in East manipulator #7986 was visually checked and looks in good shape.
Handle cable on #7986 is still routed under the spacer in the wrist and should be replaced with a new cable routed above the spacer next time it needs service. |

|
TH crane main hoist B starting delay issue appears again this Thursday. It is about 1 minute waiting time after power on the crane. this is an old problem we spent so much time in investigation and tried solve during last summer and fall. During this period, the delay time became shorter and the problem disappeared completely in November. It worked fine since then until this this day. TH crane still works fine other than it. I will watch in this issue closely. |
