Boom Truck Hydraulics – Making Sure You Get the Best Service

How Hydraulics Work

If you use any kind of truck mounted crane, you will know how the hydraulics work. A hydraulic pump places downward force on one piston, which transmits force to a second piston. The force is transmitted through an incompressible liquid – usually oil. The efficiency and smoothness of operation that hydraulic systems are known for depend on clean oil.

If dirty oil, dust or debris enters your hydraulic components during repair or servicing, the longevity and performance of those components may be affected.

Evaluating Your Repair Facility

The article in Machinery Lubrication discussed the things you should look for in a good repair facility. Here is a brief summary:

Look for signs that the shop is clean and organized. Any sign of disarray may indicate that work is not done to your standards.
The workbenches where repairs are done should be far from tools that throw off lots of dust and debris, like lathes, sandblasters, grinders, welders and torches.
Clay-based absorbents, used to keep floors dry, can also generate lots of dust. A shop should use absorbent pads to take care of spills.
Solvent tanks are used to clean parts. Check that the kind of solvent used is compatible with the seals on your equipment. Also, verify that the solvent tank is filtered and cleaned regularly to ensure that dust and debris do not get onto the equipment being cleaned.
Compressed air is used throughout a repair shop, but it can blow lots of dust around. The shop should use an air source that is filtered, dried and lubricated.
