SAFETY INSTRUCTIONS
Vestil strives to identify all foreseeable hazards associated with the use of its products. However, material
handling is dangerous and no manual can address every conceivable risk. Ultimately, the most effective way to
prevent injury is to apply sound judgment whenever using this device.
Electrocution Risk: Avoid contact with live electrical wires
WARNING
Improper or careless use of this product might result in death or serious personal injuries.
•
Read and understand the entire manual before using, inspecting, or servicing the plate clamp.
DO NOT
use this device until you read and understand the entire instruction manual. Read the manual to refresh your
understanding of proper use and maintenance procedures. Review the instructions and safety messages included
in the manuals for your crane, trolley, hoist, and any other device used in conjunction with the clamp. Use this
device as instructed in this manual. You must also follow applicable provisions of
(BTH), and all laws, regulations, codes, etc. that apply to BTH devices where the clamp is used.
•
DO NOT open a clamp while lifting or moving a sheet of material. BEFORE opening a clamp be certain that
the sheet material is entirely supported by the ground or other surface, and is fully stabilized e.g. can’t fall over,
roll, slide, or move in an uncontrolled manner. If a second person is needed to immobilize the material, find
someone to help you. DO NOT open a clamp while using it to lift or move sheet material.
•
Inspect plate clamps as instructed in
on p. 7-8. Acquire a copy of the most
. Apply all applicable inspection procedures in ASME B30.20.
•
Maintain plate clamps according to the
manual. T
hese procedures
supplement
the maintenance recommendations of ASME B30.20
. If any
instruction in this manual conflicts with B30.20, then you should apply the provision in B30.20.
DO NOT use this
lifter if it is damaged, malfunctioning, or missing parts.
•
ALWAYS attach the plate clamp to a safety hook to prevent accidental/unintended detachment. DO NOT
connect the clamp to a safety hook that does not function properly or that is damaged.
•
Clean and dry the sheet material before attaching plate clamps to it. In particular, clean the material where
clamps will be attached. Debris on the surfaces of the sheet material could impair the connections between
clamps and the material.
•
Make sure that the path of travel is clear of debris and obstacles BEFORE picking up the load. Make sure that
no person is in the travel path.
•
DO NOT lift and move a sheet of material unless it balances when suspended. Attach as many clamps as
necessary to balance the load while it is suspended. Load balancing is discussed in
on p. 5-6.
If a load cannot be balanced, do not use the lifter to elevate it. Select another lifting device.
•
Only lift the topmost sheet of a stack. Make sure that there are no items on the sheet before lifting it.
•
DO NOT attach the clamp to a side edge. ONLY attach the clamp to the top edge of a plate.
•
DO NOT lift more than 1 sheet at a time.
•
DO NOT lift a sheet from a vertical position. HPC’s are horizontal plate clamps. They must ONLY be used to
lift a plate as shown in Step 2 on p. 5.
•
DO NOT sit on or apply any load to the sheet material held by the clamp.
•
DO NOT exceed the capacity of the clamp. Never attempt to lift material that weighs more than the capacity of
the clamp. Clamp capacity is provided on the data tag which is fastened to the face of your clamp.
See Data Tag
•
DO NOT lift a load higher than necessary. See
•
DO NOT raise the load over your feet or any other part of your body.
•
DO NOT lift people or carry material over people. DO NOT lift any apparatus supporting/carrying people such
as a work platform. The clamp must ONLY be used to lift single sheets of material.
•
DO NOT get in front of or behind a suspended load while moving it. Stand to one side of the load.
Keep feet
out from underneath the load at all times. Make sure that clothing cannot become entangled in the load, the
rigging, or the clamps.
•
Keep an eye on the load at all times while it is suspended.
•
DO NOT leave suspended material unattended. Move the load to the unloading location, land the load, and
disengage the clamps before leaving it.
•
Referring to American National Standard ASME BTH-1, this clamp is BTH design category B (loads and
variations which are severe and not accurately defined), service class 1 (20,001 to 100,000 load cycles). DO NOT
