Special blocks for overhead crane

DGM ENGINEERING s.r.l. designs and achieves special blocks of all size and capacity to satisfy needs of our customers. We can realeze blocks with different configurations and sizes and with various options:

  • roation locking hook;
  • protection from heat sources;
  • copper plating or brozing of the hook to avoid sparks and explosions into highly flammable atmospheres;
  • thermal insulation of the hook to avoid sparks and explosions into highly flammable atmospheres;
  • hardening of gorge end of the pulleys to increase their duration against usury of rope;
  • particular surface treatments for offshore environment and nuclear power plants;
  • special paining under request.

 

 

Spare parts

We supply pulleys that are in the catalog till 510 mm of outer diameter, with radail bearings previously greased that has a cantral elestic ring of shoulder. Also, we offer special pulleys turned from fullness or laminated (till 2000 mm of outer diameter) with following options:

  • hardening of gorge end through a localized process of induction hardening to increase the duration of the pulleys against the usury caused by the contact and the friction with the rope
  • skin-deep finishing cycle (painting and/or galvanzing)
  • deep groove ball bearings and/or cylindrical roller (to support also axial pressure) 

 

We provide eye and shank hooks, shorteners, bells, connecting links, chain portions, security kit for the total closure of tongs and rivets (standard components for parts of linkage with rope and chain).
