There are many types of chain hoists on the market we will have a look at these
three types which are the most used ones in our job the manual chain block this
is used for all kinds of operations and is the most used one the standard
lifting height is three meters but it is possible to get them in virtually any
height and with any swl you need leave a hoist this is generally used for
lightweight and short lifts and when a lightweight and handy tool is required
standard lifting height is 1.5 meters but it is of course possible to get it
with whatever lifting height you need pneumatic chain hoists this is usually
quite heavy equipment used for heavy lifts at large Heights or as a
substitute for a winch where a permanent hoisting gear is required typical
locations are the tops of Pump Rooms and engine rooms these are normally ordered
with a specified length of chain before using a chain hoist you must make sure
the swl of the hoist is adequate for the load make sure the structure you suspend
the hoist to is of sufficient strength for the load including the weight of the
hoist check that the safety catches on the hooks are fitted and in good
condition check that there are no twists or knots on any of the chains test the
operation of the chain including how to hoist and lower check that the chains
can move freely and that the ratchet sounds crisp make sure the hoists
operating range height of lift is sufficient for the task warning the use
of damaged toys may cause severe damage or injury to both material and personnel
always make sure that the load wringing seats correctly in the hawk and the
safety catch is closed always position the hoist directly above
the center of gravity of the load never load the tip of the hook use the low
chain of the sling travel load above personnel use
excessive force on the hoisting chain or lever leave a load suspended without
additional security rigging apply shock loads on the hoist
