When it comes to machinery moving, you cannot
even think of a successful job without the use of
hoists and pulleys for the purpose. Hoists are
mechanical devices for lowering, lifting, and
transportation of various objects using cables
wrapped around wheels. Passing cables through
wheels provides mechanical advantage and makes
heavy object lifting quite easy and effortless.
Besides the myriad industrial uses, hoists are
also used when caring for disabled or in auto
repair scenarios. Cables and power sources
related to these vary as to serve numerous
purposes. Pulleys are among the simplest of the
machines used by humans when it comes to lifting
heavy objects. These invariably contain a wheel
with strung rope. Together with the hoists,
pulleys are the oft-used components invariably
used by all rigging companies in
California.   Some important hoist types

• Chain these contain metal interlocks for
  lifting our cable mechanisms. You can use them
  for lifting weights up to 7.5 t maximum. For
  heavier loads, you need to use wire ropes
  instead. Extremely durable chain hoists require
  minimal maintenance.
• Manual these are the most rudimentary
  varieties originally used when power sources were
  yet to be invented. You can find them today too
  but not that commonly.
• Wire rope these contain individual wire
  strands wrapped around core. Made with carbon
  steel these are used by rigging companies in
  California for heavy lifting purposes compared to
  the chain varieties. Speed of lifting is faster
  with wire. The only downside is that these are
  more expensive than chain hoists.
• Pneumatic these are air powered weighing
  40-50 less to electrical varieties. Easy to
  install and repair these are completely
  hassle-free and are resistant to dampness,
  weather, and dirt.
• Electric these are the commonest hoist type in
  industries, as it requires only a single operator
  for functioning. These hoists find application in
  plastic, lumber mills, and manufactured housing.

Depending upon the arrangement of pulleys it may
provide mechanical advantage to the users so that
you can lift heavy loads with minimal work. Also,
with these pulleys you can apply same force
amounts in varied directions. Other systems offer
both these benefits simultaneously to the users.
The commonest types of pulleys in use for rigging
and lifting in California and other purposes as
well include the following.

• Fixed these contain a stationary pulley with
  rope movement ideal for redirecting force instead
  of direct lifting.
• Compound these contain both movable and fixed
  pulleys together. You will attach the weight to
  rope associated with the movable pulley. This
  movable pulley in turn is attached to the rope
  from the fixed pulley. Use it for redirecting
  required force direction together with total
  force workload.
• Movable not the wheel but the pulley remains
  attached to stationary surface in this case. You
  can gain mechanical advantage with these and you
  will attach the heavy load to the wheel instead
  of the rope, which will be used for lifting.
