A load pin is a form of load cell that can be used to replace clevis, sheave, pivot, normal shaft, or equaliser pins directly. Load pins are dependable, easy-to-install overhead weighing devices with capacities exceeding 500,000 pounds in many cases.
Load pins are sturdy and corrosion-resistant since they are made of stainless steel. Load pins can be employed in a number of applications, including naval operations, because the strain gauges are completely internal.
How do load pins work?
Load pins have a drilled centre with internal strain gauges that measure force. These strain gauges, like other load sensors, monitor the change in electrical signal generated by force applied in a specified direction. The weight measurement is then converted from the change in electrical signal. Load pins are designed to be permanently mounted in a sheave, pulley, or crane system, allowing them to be used to measure vertical or horizontal strain in a consistent manner.
A load pin’s outside circumference contains two grooves that define the pin’s area between the measured forces. On the central section of the pin, the lug or sheave applies force in one direction, while the fixed support applies pressure in the opposite direction. The force or tension recorded by the load pin strain gauges is this.
Load pins and other integrated overhead weighing systems enable overload protection without compromising an application’s headroom. Load monitoring with an integrated load pin also aids in safety and the prevention of costly overhead equipment overload damage.
Where are load pins used?
Integrated load pins can be used in nearly any application that has a repetitive load path, such as:
- Cranes (mobile, bridge, jib, gantry and straddle)
- Bearing blocks
- Hoisting gear
Agriculture, chemical processing, energy production, marine cargo, and port shipping operations are just a few of the industries that benefit from integrated overhead weighing solutions.
