Rough-terrain cranes are designed to travel over uneven, muddy, and harsh ground surfaces. However, there is a risk of tipping over when the crane is not properly operated. Therefore, it is important that you and your workers choose the right method for using the crane and implement safety procedures to reduce the risks of a tip over. To help get you started, here is what you need to know.
What Methods Are Available?
The rough-terrain crane can be used to lift a load using the pick and carry, stationary and over the front, or stationary and 360 degrees methods. Knowing the differences between the methods is important to avoiding a tip over.
The stationary and 360 degrees basically means that the boom can rotate around the base. The crane will not move using this method. If you opt for this method, the load capacity changes from the recommended if the boom remained stationary.
As the boom rotates while holding the load, the weight placed on each side of the crane shifts. The shift means at any given moment, one side is more vulnerable to tipping over. Check the load capacity to ensure you are not exceeding it.
The stationary and over the front allows you to a larger load because the boom does not rotate. There can be limitations to the amount you can carry. The size of the tires will dictate just how much is appropriate for the crane.
Pick and carry essentially means you can move with the load, but the crane has to basically creep. Moving faster could result in a tip. Verify the speed allowed with the rental company.
What Safety Precautions Can Be Taken?
The most important safety precaution you can take is to avoid overloading the crane. A large number of crane accidents occur because the load capacity has been exceeded. Verify that the equipment being used is correct. The wrong sized crane and sling could increase the chances of a tip over.
Even though you are experienced in crane operations, it is important to carefully check the chains before using the crane. The chains need to be taut. If not, slack in the chains can occur and if that happens, the crane could be accidentally overloaded.
Consult with the crane rental company to learn more about using rough-terrain cranes safely and to determine the best method for moving loads while you have the rental equipment.
