  • The specialists examined the gearbox and discovered no flaws. They saw that the shaft, as was the drum, was being turned by hand, with no inappropriate sounds or issues. Our specialists tested the gear oil and hydraulic fluid for dirt but found none.
  • After that, the troubleshooting was started and the hydraulic brake was checked first. The brake discs and brake flange were found to be damaged and broken.
  • Alatas Turkey experts searched the shop for extra brake block parts and discovered whole sets of brake blocks. They then transported the spare pieces to the Crane and began assembling them.
  • The brake flange of the gearbox was connected. Following that, new brake discs (inner and outer) were installed in the manner specified in the handbook. They examined the springs but found no problems, so the technicians mounted the spring blocks on the brake flange.
  • The experts completed all of the required modifications, such as raising the hydraulic motor and hoisting the hydraulic motor’s block. Flexible hoses were also installed, and gear oil was added. The specialists from Alatas Turkey then disconnected the hydraulic system’s air supply. They tested the Crane and discovered that the problem had been resolved.
