What’s a forklift scale?

[ad_1]

A forklift scale is an accessory or piece of equipment that may be standard on some elevators and be an option on others; allows the weighing of objects lifted by the forklift. Scales typically have a digital readout and might even have a built-in printer so that weights can be properly documented. Scales may be able to process weights in kilograms or pounds, and the scale can be calibrated to account for any accessories on the forklift.

Typically, a forklift scale works using sensors found in the forks themselves or in the lifter’s hydraulic system. It works by measuring the resistance of the object it is lifting, thus determining and displaying an accurate weight. The key to the balance is to correctly translate the measured resistance into an accurate weight. While there are alternative ways of weighing, a forklift scale offers a certain level of convenience, especially in busy shipping facilities, by eliminating the need for a separate procedure.

The system typically works with electricity already available on board the forklift. In some cases, the electrical requirements of the scale may exceed the amount of electricity available and additional battery power of some sort may be required. Generally, the installer should be able to determine if sufficient electrical power is available.

The user interface on a forklift scale is housed in a heavy plastic or metal case and usually bolted directly to the forklift. Generally, control buttons will include at least an on/off switch, a way to zero the scale, and possibly a print button. The display can include a backlight so the operator can read the weight even in dark conditions, which are common when loading freight trucks at any time of day, but especially at night.

Transportation and manufacturing companies are major consumers of forklift scales, where weight measurement can be essential to operations. For example, if a forklift operator can weigh the load while loading a truck, he will know if the truck is a legal weight when it hits the road. Also, for shipping companies, it can be a way to raise revenue when shippers accidentally or deliberately understate weight. It could also act as a safeguard to help prevent lifting heavier objects than the forklift is rated for.

A forklift scale can only be rated to weigh accurately up to a certain weight. It is up to the user to understand the limitations of the system being used and to use it correctly. Incorrect readings could potentially cost a business a great deal of money in fines and damaged equipment, and could also be a very serious safety issue.
