At the end of this module, you will be able to:
- Describe the importance of preventing roll damage
- List the key guidelines for roll protection from damage
- List the factors for selecting a proper clamp truck and clamp
- Identify and describe the roll clamp and its components
- Identify the variables that determine the required clamping force
- Identify and describe the typical causes of structural, end, edge, and belly damage on paper rolls
- Identify and describe roll handling practices for preventing roll damage
- Identify safety hazards associated with clamp trucks
The following key questions are answered in this module:
How is roll damage prevented when handling paper rolls?
Damage can be minimized by wrapping the roll with a protective outer layer, selecting and maintaining the right equipment, following standard handling procedures, and by avoiding any unnecessary handling of rolls.
How is the proper roll clamp truck selected?
The proper equipment depends on the roll weight, width, and diameter, the paper type, and handling and storage requirements.
What is the clamp force factor?
The clamp force factor (CFF) is used to determine how much force can be applied to a roll without causing damage. It is the ratio of the clamping force to the weight of the roll. The CFF varies by paper grade.
What are common roll damage categories?
Most damage falls into the following 4 categories: structural (e.g. out of round), end, edge, and belly damage.
How can out of round rolls be prevented?
From an equipment standpoint you should ensure the clamps pads are in good condition and the appropriate clamping force is applied.
Below is a transcript of the video sample provided for this module:
Edge damage prevention practices include ensure the clamps never extend beyond the top or bottom edge of a roll. If more than one roll is being carried, a clamp with multiple pads should be used. When carrying more than one roll, center the clamp pads between the rolls. Prior to rotating rolls, ensure the mast is vertical, the roll center of gravity is aligned with the center of rotation, and there is enough clearance between the roll and floor as well as between the roll and a wall or nearby equipment. Tilt the mast toward the operator cab while carrying a roll. Tilt the mast back to vertical before lowering the roll, and align rolls when stacking.
