London Pattern Pulley Blocks
London pattern pulley blocks are available and should be reeved
for various heights of lifts as required. Bear in mind when considering
the load capacity required that one man can exert a pull of approximately
70lbs only.
|
The above configurations are available.
When using pulley blocks on Tackles friction has to be taken into account,
for example
to lift a load of 1.680 lbs with a 4 3/4" diameter 2 sheave and a 3
sheave tackle the effort or
pull is expected is 420 lbs and a suitable winch should be used. For
use as hand operated
tackles it is assumed that one man can exert a pulling force of about
70 lbs
Please state capacity required when ordering.
