SyncMaster-ing Precision & Safety

Track frames needed to be removed from a Hitachi EX5500 Hydraulic Excavator – operating weight 522 tonne. The Durapac SyncMaster combined with 4 x 500 tonne capacity RD-50018 cylinders provided a high level of precision and safety. The precision was particularly important during re-assembly of the track frames and allowed the mounting bolts to be efficiently assembled. The SyncMaster has a number of key safety features that were used during this jacking procedure including centre of mass monitoring, maximum loads per lift point and fine tolerances of 0.5mm between cylinder displacements.
