Gosan produces over 25.000
sheaves each year with an average diameter of 1000 mm.
the majority are welded
machined
types, i.e.,
manufactured from rolled steel
(or forged steel) and then welded
and finished. we also make
other types of sheaves such as
plastic sheaves and solid or
cast sheaves, although in
smaller numbers.
Gosan has always aimed to be
a point of reference in the
market for the supply of
mechanical lifting and hoisting components. For this reason,
at the end of the eighties, we added hook blocks to our catalogue.
These products complement
the rest of our range and offer manufacturers of lifting and
hoisting equipment, and even
final users, the possibility
of using a single supply source
for their mechanical components.
In line with the aim of offering a
wide range of complementary products to manufacturers
of lifting and hoisting equipment, Gosan included the manufacture
of couplings in its catalogue
right from the start.
Production of these parts has
been adapted to the changing demands of the market as a
result of continuous development
and innovation on the part of our technical department.
Wheels are generally made of hardened and tempered
42 CrMo4 alloy steel.
Wheel rolling face is induction hardened to reach a 400 to 450 HB hardness or higher, and deph
higher than 8 mm. Hardening treatment is guaranteed to show no discontinuance throughout the
wheel rolling surface.
Motor shaft sizes and rolling
surface widths can be modified
to suit Cus-tomer´s requirements.
