Ramsay Test Rigging and Material Handling

Question 1

A wire rope sling is rated at 2 tons in a single vertical hitch. When rigged as a basket hitch with both legs hanging straight vertical (90° from horizontal), what is the rated capacity of the lift?

Accepted Answer

4 tons

Answer

In a vertical basket hitch, the load is shared equally between two legs. Each leg can carry its full 2-ton rating, so total capacity = 2 × 2 = 4 tons. As the sling angle decreases from vertical, a derating factor applies.

Question 2

Per ASME B30.9, a wire rope sling must be removed from service when it has:

Accepted Answer

Six or more randomly distributed broken wires in one rope lay

Answer

ASME B30.9 specifies immediate removal when there are 6 or more randomly distributed broken wires in one rope lay, or 3 or more broken wires in one strand of one rope lay. Surface rust alone is not an automatic disqualifier; a kink that cannot be straightened — not one that can — requires removal.

Question 3

What does the abbreviation WLL on rigging hardware mean?

Accepted Answer

Working Load Limit — maximum load the component may handle in normal service

Answer

WLL (Working Load Limit) is the maximum load a piece of rigging hardware is designed to support under normal, intended conditions. It already incorporates the design factor of safety; it is NOT the breaking strength.

Question 4

A chain hoist is designed to be used:

Accepted Answer

For vertical lifting only — never for side-pulling or tip-pulling

Answer

Chain hoists are engineered for pure vertical loading. Side-pulling or tip-pulling creates off-axis forces that overload the hook, frame, and load chain in ways the hoist was not designed to handle, and can cause catastrophic failure.

Question 5

What is the primary purpose of a tagline during a crane or hoist lift?

Accepted Answer

To control the load's rotation and prevent uncontrolled swinging

Answer

Taglines are guide ropes that allow personnel to control a suspended load's orientation and prevent it from spinning or swinging into obstacles — without placing hands near the load or rigging. They do not bear the weight of the load.
