Why Hydraulics?

Hydraulics, or fluid mechanics, offer extremely high forces with compact construction, which gives portable lifting, pushing and pulling power for numerous applications.  There is no other kind of power transmission that will provide comparable high forces with the same compact size.

 

Hydraulic Tools

 

The specialised design of hydraulic tools provides flexibility to engineers looking for a solution to lift, pull or push in general assembly and repair jobs.  The compact construction provides a versatile tool that is capable of being used in a number of universal applications.

The robust construction of the Yale range of hydraulic cylinders have been designed to withstand the arduous conditions experienced in heavy duty industrial applications.  Depending on the application, the user can specify from a range of hydraulic hand pumps, electrically powered pumps (Hydraulic power packs) and controls in 3 Phase and single phase construction.  Yale also offers a range of air powered pumps and petrol engine pumps where mains electricity is not available.

 

Basic Terms in Hydraulics

 

Pressure

 

Is the system pressure generated by the hydraulic hand pump, however this can also be produced from an external power source.

 

Force

 

Is the pressure transferred by the hydraulic cylinder proportional to the laod up to the maximum capacity.

 

Stroke

 

Is the piston rod travel distance to be achieved by the relative force (no-load stroke, loaded stroke, return stroke)

 

Piston Travel Speed

 

Is the time taken for the piston rod of the hydraulic cylinder to travel through a fixed distance acceptable

 

Hydraulic Cylinder

 

Are available in different designs with two basic types:

 

Single acting

 

The piston travel is achieved via hydraulic pressure and returned by spring force (Pressure build up in one direction only)

 

Double acting

 

The piston travel is achieved via hydraulic pressure in both directions (Push forces and pulling forces are possible, however, pulling power will always be lower due to the available area of the piston)
