FRAME : Rugged steel frame shaped to occupy minimum
headroom, ensures permanent alignment of
spindles and gears, encloses and protects the load
chain wheel. Detachable steel cover totally
encloses the gears. Hand chain wheel cover
protects the hand chain wheel and brake unit.
HOOKS : Hooks are of forged alloy steel. Top hook swivels on
balls housed in cross head. For chain hoist on single
fall of chain, bottom hook rotates on balls housed in
a cross head swivel. For chain hoists with 2 falls the
bottom hook rotates on balls housed in hook holder & is supported by bottom block frame.
SAFETY LATCH : Every bottom hook is equipped with a safety latch -
a safety latch for top hook is an optional
LOAD CHAIN WHEEL : Made from spheroidal graphite iron, has pockets
accurately cast to receive calibrated load chain.
Bottom Block wheel for chain hoists with two falls
are fitted with needle rollers.
LOAD CHAIN : Alloy steel Grade 80 to international standards. All
chains are electrically resistance welded & heat
treated to give ductility, toughness and wear
resistance. Accurately calibrated, pitched and
polished to ensure free movement. Each link is
tested to twice the safe working load and can
withstand shock loads.
GEARS : All gears are accurately machine cut from alloy
steel and case hardened to ensure long life.
BEARINGS : Load wheel mounted on needle rollers housed in
bush bearing thus reducing effort required for
LOAD BRAKE : The precision self actuating screw disc type
mechanical brake engages instantly and provides
uniform performance with rated capacity. When
lowering, a load is under perfect control at all times,
that is exceptionally valuable where accurate
movement is demanded for spotting loads.
Ratchet wheels are hardened and surfaces ground
to maintain parallelism, with adequate thickness to
engage properly with pawl.
HAND CHAIN WHEEL :
Hand chain wheel having bore with multistart
threading and pockets accurately cast to receive
calibrated hand chain. Hand chain wheel cover
prevents chain from snagging and fouling.
LUBRICATION : Totally enclosed gear case is packed with sufficient
grease during assembly.
TEST : BRAD hand chain hoist are tested for 50% overload
at works in support of which test certificates are
