Medieval crane
Medieval cranes were used to build
European cathedral. The crane was fixed on the top
As it was being built, on the wall
Supplied by men who ran inside the two big wheels
On each side. Cranes were also used in medieval harbors
And at the shipyard.
Mobile crane

Loader Crane
The loader crane is powered by hydraulic power
Arm that fits the trailer used to load the equipment
A lot of sections on the trailer

Overhead traveling crane
Also an interrupted crane, referred to as this type
Normally used in factories with some of them
Very heavy load can be lifted. There is a hoist
Set as a trolley to move in one direction
Along one or two beams moving at an angle
Rising or ground level along that direction
Truck mounted, assembled along

Comparison with compact excavator
Both of these machines are realistic and popular,
Productive, and they are both helping lying down
Lot of cable and pipe on the ground. They are
Both can work, there is a difference
How to do when stacking
Other than practical installation of housing.
Size and price
Average excavation depth for practical installation
Housing applications are between 40 and 48
Inch the above basic trencher
The depth is 20 to 30 horsepower engine
The cost is about 40,000 dollars.
There is the most popular type of dense excavator
Using a class of 2.5 ton size 30 HP
Engines and costs around the same price. this
The biggest difference between the two surfaces You
I need a trencher to dig deep. 2.5 metrics

More than legs, trenchers can dig
About 100 engines are needed in the deep part

With the expendable cost of the trencher,
The difference tends to equalize the productivity of time

Keep it in mind as it comes to the choice
It depends on your needs. There are several
