Vestil CH series - Manual (Page 11)

Maintenance and Inspections:
A designated person must verify that the device complies with all regulations, codes, and standards that
apply to “Under-the-Hook Lifting Devices” in the location where the coil hook is used. The person
designated to conduct inspections must do so before the coil hook is used for the first time, and EACH
time the hook is installed for use.
Inspections:
The end-user is responsible for performing inspections as recommended in ASME B30.20,
which categorizes examinations based on regularity of performance. Highlights of the recommended
inspection procedures appear below. The reader must recognize that Vestil has merely reproduced an
outline of the ASME recommendations, and the full explanations as given in the published standard must
be followed.
DO NOT use a coil hook that is structurally damaged. Structural damage includes, but
is not limited to bending, warping, cracking or other deformation of the main body frame and especially
the connection opening (see FIG. 1 on p.6), handle, or bracket weldment. Contact Vestil for directions if
an inspection reveals ANY structural damage.
Inspections Before & During EVERY lift: visual examination must be performed by the operator prior to
AND during each lift. In particular, the operator should inspect for:
1. Debris on the load surfaces; AND
2. Condition and operation of the controls.
Frequent Inspections: the specific meaning of “frequent” varies from daily to monthly depending on the
service classification (normal, heavy, severe, and special/infrequent) of the coil hook. Definitions of the
service classifications appear in ASME B30.20. The operator or other designated person(s) should
visually inspect the coil hook for:
1. Deformation, cracking, or excessive wear of any part of the coil hook;
2. Operating mechanisms for conditions that interfere with proper function; AND/OR
3. Loose or missing fasteners, stops or nameplates.
Periodic Inspections: complete visual inspections performed AND recorded by a qualified person. The
inspection should specifically look for:
1. Loose bolts or fasteners;
2. Excessive wear of friction pads, linkages, and other mechanical parts; AND/OR
3. Excessive wear at the points where the hook connects to the hoist hook, and load support
clevises or pins.
Maintenance: the end-user must implement a maintenance program to ensure the proper function and
safety of the coil hook. A qualified person may establish a program that is used in preference to the
maintenance procedures described below. However, if you apply the procedure below, complete EVERY
step each time maintenance is performed.
ONLY qualified persons may perform maintenance on the coil hook.
Step 1: All sources of power must be disconnected, locked out and tagged, “Out of Service.”
Step 2: Disconnect the coil hook from the hoist hook, and tag it as, “Out of Service.”
Step 3: Perform all adjustments identified as necessary during any inspection (every lift, frequent, or
periodic). Consult ASME B30.20 para. 20-1.3.1 through 20-1.3.5 for recommended inspection
procedures.
Step 4: If other conditions exist which require new/replacement parts to repair, contact Vestil to order
replacement parts. Deformity, corrosion, rusting, or excessive wear of fasteners and/or the hook jaw
warrants immediate replacement of the affected part(s).
The reader should understand the significant difference between “ Adjustments [and]
repairs,” and modifications. An adjustment or repair refers to a simple correction that restores the hook to
