Item
has introduced a new heavy duty braked swivel castor into the MB building kit
system. Designed to complement the existing heavy duty castors already in the
Item system (but with one very important difference), the castor will support
the same load of 4500N. The castor wheel is again of cast iron with a
polyurethane tyre, has sealed ball bearings on both axle and swivel, and a foot
operated brake. Where this castor differs is in the foot operated brake, which
again locks both swivel and wheel, but in this case is operated by pressing a
lever on on the trailing edge of the castor rather than the leading edge.
With two of each type of castor fitted to a large and heavy trolley, all four
brakes can be applied, rather than two always being inaccessible. This greatly
reduces the risk of heavy loads being left unattended, sometimes on uneven
sloping ground, and at worst, effectively with only one brake preventing the
load running away.
