Discussion: More than one roll being carried.......

I work at a newsprint mill. We only carry two rolls in split arm clamps. Winding tolerances for paper rolls means you can have different diameters and if the top roll is even slightly larger than the bottom you risk dropping the bottom roll. If the bottom roll is larger diameter then the top roll will not be clamped in a single arm clamp and is simply riding on the bottom one - an accident waiting to happen.

TC17:

Using a single face clamp for carrying more than one roll (I'm assuming paper roll) simultaneously is considered an unsafe condition. One factor that determines lifting capacity of the paper roll clamp is the friction surface area of the clamp. Splitting the single clamp face between two rolls reduces the friction surface area per roll. This reduction could lead to a load slipping through the clamps with potential for damage/injury/death.

Split clamps should be used for carrying additional rolls. Each roll should have a clamp face fully engaged on the roll. The weight of the roll must not exceed the rated lifting capacity of the clamp attached to it. The total weight of the rolls being lifted cannot exceed the rated lifting capacity of the truck with attachment(s).

Many factors enter into recommended clamp placement. An excellent source of information are the Operator Guides published by Cascade (Cascorp) for their paper roll clamps (especially the Safety Rule and Roll Handling Basics sections of the guides).

Under Pressure: Choosing The Right Clamp Force Control ...

One of the common solutions to overcome product damage from high-pressure settings is to use a three-position pressure regulator, which is essentially a pressure relief valve assembly mounted on the forklift. As the name implies, there are three positions, and each one regulates how much pressure is being relieved in the hydraulic system (crazy, I know). The assembly is typically mounted in a convenient location relative to the operator for ease of use. The truck&#;s mast, cowl, and operator compartment are some of the most commonly used locations, although the closer you can mount it to the forklift&#;s control valve, the better. The pressure is adjusted by simply moving a lever to one of three preset positions.

Pressure can be set specifically for your loads for each of the three settings, which allows operators to quickly adjust on the fly. A pressure gauge on the valve will also display the current setting for reference. Given that there are only three different pressure settings, this solution is best suited for applications with less variety when it comes to load weights and sizes. It&#;s also the cheapest option, so applications with less throughput can also benefit since minor manual adjustments from time to time are usually less impactful to your bottom line.
