Background
The crane has been in service for seven years with little downtime and working extensive duty cycles. The luffing racks were experiencing pressure angle loss and damaging drive pinions. |
Alatas’s solution
Because the client had never executed this type of repair previously, and the replacement took 150′ above the ground, they asked ALATAS to create a replacement protocol.
