Point load on ESCO rams and jacks
Point load on cylinders, rams and jacks can cost you hundreds of dollars, or worse, the health and well being of your service tech.
What is a point load?
· A point load happens when the jack, cylinder or ram is extended under load and the load is not centered on the lifting point.
Why is a point load bad?
The most important reasons a point load is bad:
· It is a very unsafe way to lift a load.
· It can cause injury or death to the service technician should the cylinder, jack or ram kick out from under the load.
· A point load will also cause extensive damage to the walls of the cylinder and piston rod and almost always to the protective saddle on the top of the piston rod.
How does a point load happen?
A point load can happen the following ways:
· Improper lifting. The Cylinder, Jack or Ram was not centered to the lifting point.
· Load shift. Caused by uneven ground or an uneven lifting point. (Please refer to the ESCO jack plates and Cribbing set.)
· Continuous load support through entire job caused a load shift.
How can a point load situation be avoided?
You can avoid a point load situation by taking the following steps:
· Lift from and against a flat surface.
· See to it that the Cylinders, Jacks and Rams used for lifting are centered to the lifting point.
· The Cylinders, Jacks and Rams are not designed to sustain a load for any length of time. You must support the load with cribbing or jack stands of proper tonnage capacities.
Please refer to the OSHA regulation for servicing tires, wheels and rims.
