ALATAS Marine Engineering (S) Pte Ltd carries out TOBU Grab overhaul at Anchorage and in the Workshop
The vessel has on board 4 pieces Electro Hydraulic Grabs, make TOBU JUKOGYO, type EHSH 120/60 (12/6 M3). On all grabs the hydraulic grab cylinders where leaking and the cylinder pins and Grab Zylinder eye pieces were severely worn and out of shape.
ALATAS Marine Engineering deployed a team of factory trained grab mechanics to remove the cylinders & pins on anchorage. The cylinders then where sent to AME(S) workshop ashore for a complete cylinder overhaul, including chroming of the piston rod and honing of the cylinder barrel. New bearing bushes where manufactures and inserted into the cylinder eye-pieces and the cylinders were pressure tested with 240 Bar on the piston side and 120 Bar on the ring side.
The repaired and function tested cylinders then were re-installed, and the grabs where fully function tested and adjusted.
Besides repairing TOBU Grabs, FUKUSHIMA Grabs, ORTS Grabs, KOCATAS and GUVEN Grabs, ALATAS also is the authorized service station for SMAG Peiner Grabs:
