FRAME
Rugged steel frame shaped to occupy minimum headroom, ensures permanents 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 bottom hook rotates on balls housed in hook holder & is supports by bottom black frame.
SAFETY LATCH
Every bottom hook is equipped with a safety latch – a safety latch for top hook is an optional attachment.
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 with stands shock load.
GEARS
Spur & helical type gears are enclosed in a dust proof gear box and are made from special alloy steel. Precision machine cut & case hardened gears mounted on ball bearings ensures smooth & noiseless operation.
LOAD BRAKE
Disk Type, spring loaded brake ensures full safety at any load position.
BALL BEARINGS
To reduce noise, gears & load chain wheel are mounted on ball bearings.
WEIGHT
