LIFTING DEVICES
GENERAL
The useof lifting devices is subject to certain hazards that cannot be met by
mechanical means but only by the exercise of intelligence, care, and
common sense. It is, therefore, essential to have competent and careful
operators, physically and mentally fit, thoroughly trained to the safe
operation of the equipment and the handling of the loads. Serious hazards
are overloading, dropping or slipping of the load caused by improper
hitching or slinging, standing or crawling under a load, swinging loads,
obstruction to the free passage of the load, using equipment for a purpose
or a manner for which it was not intended or designed..
EYEBOLTS
A straight lift is preferred when using eyebolts. An angular lift places
additional stresses on an eyebolt, above that of the load to be hoisted.
Ifthe situationnecessitatesan angularlift, thesafe workingload forangular
lifts shown in Fig. 1 and Fig. 2 should be used.
Whenmultiple eyeboltprovisions aredesignedinto alift, itisrecommended
(in most applications) that a spreader bar be used. (See Fig. 9 which
illustrates a typical spreader bar arrangement.)
No greater stress should be allowed than that given under Safe Working
Load in Fig. 1 and Fig. 2.
To obtain greatest strength from an eyebolt, it must fit reasonably tight in
the hole with at least 90% of the threaded length engaged.
Eyebolts should never be welded or subjected to heat in excess of 900F
[480C].
Eyebolts should never bepainted orotherwise coatedwhen usedfor lifting,
as such coating will very likely cover up flaws.
Eyebolts should be routinely inspected for defects and if any defects are
found,theyshould bedestroyedby melting,crushing, orcuttingclearacross
the eye.
