Peak line tension　流纜繩張力

Peak line tension

This wheel calculates the peak line tension of samson ropes utilized in negative blocking rigging operations, and compares the calculated result to the working load limit of the specified type of samson rope.

Estimates made by this calculator assume fulfillment of al of the following responsibilities:

All worker are properly trained in arborist operations and strictly follow all safe arborist working practices. Safety is your responsibility! Practices which affect line tension include but are not limited to:

Remove all slack from rigging line when tying off or friction wrapping the line prior to completing the topping cut.

Allow the rigging line to slide on a lowering device to reduce peak load. When in doubt let it run!

All samson ropes utilized in the operation are in good usable condition, and users follow samson guidelines for inspection, maintenance and retirement of ropes, found at samsonrope.com

The guide is applicable only to the listed samson ropes in good, usable condition

NOTE: actual peak line tension may, at time, be lower than the peak line tension shown on the calculator. However, safe practices require working under the guidelines set forth in this calculator.

This calculator provides certain information regarding peak line tension. This calculator does not replace the need for proper training in arborist operations and should only be used to augment existing safe working practices. Safety is your responsibility.

This calculator applies only to the listed Samson ropes in good usable condition, you must carefully follow the instructions on accompanying sleeve and Samson guidelines for inspection, maintenance and retirement of ropes, found at samsonrope.com
