Wire Rope

The most important component of the hoist is the wire rope. It should be carefully
monitored and checked during use, and after extended periods of storage. Always
ensure the wire rope is lubricated. Do not allow the rope to be bent sharply,
pinched, tied in a knot, or otherwise damaged.
Most Beta Max portable hoists have single-wire rope rigging. However, there are
some models that can be purchased, or fitted, for double-rope rigging. (Only Beta
Lite, Gemini Plus, Leo, and Leo XXL models can be double-rope rigged.) The
advantage of double-rope rigging is the ability to lift twice the weight of single
rigging. The disadvantages are a reduction of the lifting height and rate of lifting
(speed) by one-half. Double-rope rigging requires an 8-inch (20.3-centimeter)
sheave and pulley, another hook, and a shackle. Typically, the hoist wire rope is
terminated with a weight (headache ball) and thimble.
CAUTION
When using a double-wire rope rigging setup, be certain the mounting/support system is rated for
the increased weight that double-rope rigging will allow. Double-rope pulley presents a potential
pinch point. Keep hands and fingers away from moving parts.
Important User Information Required for Safely Using Wire Rope
and Wire Rope Slings
Before using wire rope, it is important to know and understand some information
concerning the safe use of wire rope and wire rope slings. The following
information is an overview and is not a complete discussion. Key terms, conditions
or situations to avoid, and inspection criteria will be discussed. The intended
purpose of this information is to inform the end user of wire rope or wire rope sling
usage and is not intended to be all-inclusive. Please consult other sources for more
in-depth information. ISO 4309:2004 details wire rope in-service guidelines for
the care, maintenance, installation, examination, and discard criteria for safe
use of the hoist.
NOTE: Failure to follow these guidelines is the sole responsibility of the equipment
end user/operator. Beta Max, Inc. is not and will not be held responsible or liable for
injury or damages resulting from the end user/operator not following the guidelines set
forth in this manual.
