Per the industry’s ASME safety standard, the pipeline components must withstand a static pressure of at least two times its rated working pressure. Select your clamps based on the diameter of the boom or laydown system, and the maximum pressure ratings of the pump that will be used.
Easy to use but require tools to open and close them. This style clamp is used in areas where the delivery system may be set up for an extended time, such as a high-rise job site. They are also used in areas where there is a possibility the snap clamp handle could be disengaged inadvertently, causing a safety hazard: for instance, a pipe that is lowered into a caisson with a rebar cage in it.
This clamp has a solid link on the handle linkage, which requires the user to fully engage the clamp to ensure maximum engagement with the delivery system ends. These clamps can be installed and removed quickly. They are often chosen for applications where the line may need to be frequently disconnected or moved.
These clamps feature a male threaded eyebolt on the clamp body and a female threaded end on the clamp handle linkage. The handle can be turned to adjust the effort required to open and close the clamp. It is essential that the clamp halves are closed properly to ensure sufficient engagement on the delivery system ends. If the threaded eyebolt accumulates debris or concrete, it can restrict the ability to loosen or tighten the clamp. If the clamp is too loose, the end of the delivery system could disengage from the clamp, creating a serious safety hazard.
Often used on concrete boom truck backends. These clamps are designed to be operated by using a hammer to strike a wedge pin. Striking the wedge pin drives it into a slot on the clamp linkage to secure the two halves together. These wedge-style clamps are preferred on the backend of concrete pumps since they are quick to open or close, and work well when they are covered in concrete. The wedge on this clamp also has a hole in it for a safety pin to be inserted. This safety pin must be in place to help prevent the wedge pin from becoming disengaged while in use.
