INTRODUCTION
Engine hoist is a tool
that is used for lifting engines and other car parts, such as an engine with a
transmission out of a car. Engine hoist is just a name used to describe a tool
that can be used in car repair works for engine lifting, but also can be used
to lift heavy weights in other industries heavy objects or for lifting other
objects like boxes in stores, for wood works and construction works.

PROBLEM
STATEMENT
Manual chain hoist is one
of the most popular hoist types used for lots of lifting tasks, starting from
lifting heavy equipment in shops and warehouses to lifting engine and other car
parts in service stations. Manual chain hoists uses very simple gear system for
lifting loads and are so popular because of their ease of use and low price. Normally
manual chain hoists are slower, so you must take into account more time for
lifting and lowering a load thus it requires more energy when a person is
operating it. Installing a manual chain
hoist most of the times is quite difficult and needed to be installed above the
ground which greatly limits the number of areas this tool can be used.

OBJECTIVE
The objectives are a
guideline in order to complete this project. This project is conducted to
achieve the following objectives:
Ø To
design and built a hoist machine that is easy to operate and to lift or lower a
load faster.
Ø To
design and built a hoist machine which uses less force and better lifting
capacities thus reducing the force needed to operate this machine.
Ø To
design and built a hoist machine which can be folded or fully disassembled for
easier compact storage and easier to transport from one place to another.
Ø To
design and built a hoist machine which can be used anywhere and easy to
assemble the hoist machine.

CONCEPT
SOLUTION
Hydraulic engine hoist is
a type of hoist that uses hydraulic system for lifting loads. It is made of a
heavy duty steel construction and has got a hydraulic jack that does the
lifting part of the tool. Most hydraulic engine hoists have wheels below the
tool, so they can roll across the floor which allows to use this type of hoist
practically anywhere, the surface on which hoist can be used must be level and
firm, so hoist does not start to sink in under a load. The hydraulic engine
hoists have foldable designs and can be fully disassembled. Foldable design
means that legs of the hoist can be lifted upwards and the boom can be lowered
down to significantly reduce the length of the tool, allowing for easier
storage when the tool is not being used. Changing the tool from working to
folding position and back takes a very little time because of its quick and
convenient locking pin system.
Advantages of the Hydraulic Engine Hoist:
Ø A
hydraulic engine hoist is certainly faster and will allow lifting a load
quicker.
Ø Hydraulic
engine hoist have higher lifting capacities when working with very heavy
weights.
Ø Hydraulic
systems are powerful, precise, reliable and durable, and they are one of the
best systems when it comes to handling heavy loads.
Ø The
only area requirements for using a hydraulic engine hoist is that there must be
a firm and level surface, so the hoist can be used on a floor indoors, on
concrete or asphalt outdoors and even on a firm ground surface outdoors.
Ø This
machine is pretty easy to operate once the hoist has been assembled.
Ø Most
hoists can be folded or fully disassembled for easier and more compact storage.
Ø Hydraulic
engine hoist is cheaper than electric hoists with similar lifting capacities.
Disadvantages of the Hydraulic Engine Hoist:
Ø Hydraulic
engine hoist will cost more than a manual chain hoist with similar lifting
capacity.
Ø Hydraulic
engine hoist requires a little maintenance that consists of lubricating all
moving parts from time to time, changing oil and bleeding air of the hydraulic
jack when it does not perform as intended.
Ø If
it comes with unclear assembly instructions, so there might be some uncertainties
when assembling the tool.

CONCEPT
DESIGN
The
construction of hydraulic engine hoists consists of such larger parts as the
main frame, hydraulic jack, legs, wheels, boom and a chain with a hook at the
end of the boom.
Ø Main
Frame - The part that holds everything together is the main frame or upright
post. The main frame, haves two support plates on the sides which adds to the
durability and stability of the tool. Also, it has a handle with rubber grips
mounted to the top part of the frame, which allows moving the hoist easier when
it is carrying a load.
Ø Hydraulic
Jack - Hydraulic jack is the most important and advanced part of a hydraulic
hoist that uses a hydraulic system to lift heavy objects. It generally is a
hydraulic bottle jack that has one side mounted to the main frame and other
side to the boom. The engine hoists have special mounts on the side of the
upright post, where you can insert the pumping bar, so it does not lie around
your garage floor while not being used.
Ø Legs
And Wheels - Hydraulic engine hoists are equipped with two legs and 4 big casters
and two small casters. It has expandable
legs that provide better stability for the machine. For example, the engine is
located further into the engine compartment, so you need to lift it out with
fully extended boom. Then you can also extend legs of the hoist and move them
further below a car. It also has foldable legs which mean that they can be
lifted upwards when the hoist is not in use so it takes much less space when
stored. Legs can be quickly folded using a quick release pin system and unfolded
in the same way, meaning that you can change the hoist from working to folding
position and back usually in under a minute.
Casters are used to transport the hoist and are made with durable steel
bearings allowing moving the hoist also when carrying a load. Hydraulic engine
hoists need a firm and level surface, so wheels can roll freely on the surface
and does not get stuck into the ground when lifting a load.
Ø Boom,
Chain and Hook - To lift a load an engine hoist has an adjustable boom. It
means that the boom can be extended to reach engine blocks located further into
the engine compartment. Boom can be extended pretty quickly using a simple pin
system. At the end of the boom is a steel chain with a grab hook, where you can
attach the load.
