Series 646 Hydraulic Collet Grips 28 Safety Information
Remove flammable
fluids
Remove flammable fluids from their containers or from components before you
install the container or component. If desired, you can replace the flammable
fluid with a non-flammable fluid to maintain the proper proportion of weight and
balance.
Check bolt ratings and
torques
To ensure a reliable product, fasteners (such as bolts and tie rods) used in MTS-
manufactured systems are torqued to specific requirements. If a fastener is
loosened or the configuration of a component within the system is modified, refer
to information in this product manual to determine the correct fastener, fastener
rating, and torque. Overtorquing or undertorquing a fastener can create a
hazardous situation due to the high forces and pressures present in MTS test
systems.
On rare occasions, a fastener can fail even when it is correctly installed. Failure
usually occurs during torquing, but it can occur several days later. Failure of a
fastener can result in a high velocity projectile. Therefore, it is a good practice to
avoid stationing personnel in line with or below assemblies that contain large or
long fasteners.
Lift equipment safely
Grips that are too heavy to be lifted by hand are to be lifted with double swivel
eyebolts supplied by MTS, part number 100-263-718.
Large capacity grips are heavy, and must be lifted using hoist rings.
Such grips should be lifted with hoist rings supplied by MTS Systems
Corporation.
If hoist rings other than those provided by MTS are used, the customer must
ensure that the other grips are suitable for the purpose.
Practice good
housekeeping
Keep the floors in the work area clean. Hydraulic fluid that is spilled on any type
of floor can result in a dangerous, slippery surface. Do not leave tools, fixtures,
or other items not specific to the test, lying about on the floor, system, or decking.
Do not exceed the
Maximum Supply
Pressure
For hydraulic grips and fixtures. make sure that the hydraulic supply pressure is
limited to the maximum pressure defined by the grip or fixture identification (ID)
tag.
Do not disable safety
devices
Your system may have active or passive safety devices installed to prevent
system operation if the device indicates an unsafe condition. Do not disable such
devices as it may result in unexpected system motion.
Provide adequate
lighting
Ensure adequate lighting to minimize the chance of operation errors, equipment
damage, and personal injury. You need to see what you are doing.
Provide means to
access out-of-reach
components
Make sure you can access system components that might be out of reach while
standing on the floor. For example, ladders or scaffolding might be required to
reach load cell connectors on tall load units.
