Forklift Safety -- Proper Load Handling
• Do not raise or lower the load while moving. • Use a spotter if you don't have a clear view. • Exercise caution and adjust your driving and speed to current weather conditions, particularly on wet surfaces. • Travel at a speed that will allow the forklift to be brought safely to a stop.

Excavator Safety Tips for Before, During, and After Operation
When going up a steep slope, extend the boom and arm, and when needed, lower the bucket and retract the arm to help pull the machine up. When traveling down a steep slope, position the bucket with the flat surface resting on the ground. While retracting the arm, raise the boom and propel the machine until the front of the tracks reach ground level.

How To Troubleshoot Hydraulic Cylinder Drift | Hydraulics
Feb 23, 2016 · A popular misconception about hydraulic cylinders is that if the piston seal is leaking, the cylinder will drift down. Fact is, if the piston seal is completely removed from a double-acting hydraulic cylinder, the cylinder is completely filled with oil and its ports are plugged, the cylinder will hold its load indefinitely - unless the rod-seal leaks.

Figure 2. Load hanging on double-acting cylinder . Loss of Effective Area Because of the loss in effective area due to pressure now acting on the rod-side annulus area, the static pressure in the cylinder must increase to support the same load. Remember, force developed by a cylinder is a product of pressure and area.
