ModEvo Tension Brakes
The ModEvo brake disc was developed
at the Bedford, UK factory using Finite
Element Analysis techniques to ensure
maximum strength with minimum
weight. The design is optimized to
make best use of the cooling air
available at slow speeds, and being
bidirectional, it achieves high heat
dissipation capacity in either rotational
direction, unlike some other brakes. An
optional electric cooling fan is available
where space is limited or more extreme
heat handling is required.
Available in five sizes: 250 mm,
300 mm, 350 mm, 400 mm and
450 mm diameters, all discs are the
same thickness and use the same
brake modules and actuators. Each
disc can be specified with a minimum
of a single module, up to the maximum
number of modules that can be fitted
Brake Discs and Cooling
around the disc. This allows torque-
handling capabilities ranging from a
maximum of 659 lb.ft. for the 250 mm
disc, up to 3181 lb.ft. for the 450 mm
disc.
NOTE: If using a high speed ductile
iron disc the catalog heat rating should
be reduced by 10% as the thermal
conductivity of the ductile iron is less
than grey cast iron.
