Product Description
Hand cups with nominal diameter of 8" [20 cm] use vacuum to lift and carry
loads, as follows: A manual pump removes air from between the rubber
pad and the contact surface; a red line on the pump's plunger serves as
a vacuum indicator; a check valve allows the user to repump the cup
without removing it from the contact surface; and a release mechanism
allows the cup to disengage completely.
Maximum Load Capacity
Models TS8P & TS8M: 75 lbs [34 kg] per cup.
Maximum Load Capacity includes a 3:1 safety factor and requires the
following: attachment on clean, smooth, nonporous flat surfaces; a
minimum vacuum level of 17½" Hg [-59 kPa]; and a friction coefficient of
1. This rating is based on tests of new hand cups attached to the upper,
horizontal surface of static objects in ideal conditions. Many factors can
reduce the capacity, including: lifting a load when the cup is attached to
a vertical or inclined surface; or lifting a load that applies leverage to the
cup. See
www.crlaurence.com
for more information.
Load Conditions
This hand cup is designed to accommodate loads with either smooth
or textured surfaces; however, extreme surface variation may prevent
the cup from attaching (see OPERATION). The load's contact surface
must be relatively flat (not curved), nonporous, and clean. Moisture or
contaminants can reduce slip resistance
Environmental Conditions
The cup can be used at elevation up to 5,000' [1,524 m] and in temperatures
from 10° to 120° Fahrenheit [-12° to 49° Celsius]; however, attaching
the cup to irregular surfaces may become more difficult as temperature
decreases, due to decreasing flexibility of the cup face. Contact an
authorized dealer or visit
www.crlaurence.com
for more information.
OPERATION
To Attach
1) Position the hand cup on the contact surface so the red line will be
visible if it should appear while lifting the load. CAUTION: Test the
cup for staining or deformation of load surfaces with light colors or
soft coatings.
2) Press the cup against the load as needed to form a continuous seal
between the sealing edges and the contact surface.
CAUTION: Make sure the load is supported to prevent breakage as
force is applied.
3) Pump the plunger until the cup attaches completely. When the red
line is hidden, vacuum is sufficient for lifting. CAUTION: Do not leave
the cup attached to an irregular surface for an extended time, as this
might distort the cup face, making subsequent attachments difficult
or impossible.
4) Check the plunger frequently to make sure the cup remains securely
attached. If the red line appears while lifting, set down the load
immediately and pump the plunger until the red line is hidden again
(see WARNINGS).
To Release
1) Set the load on a secure support.
2) Press the valve release lever until the cup disengages completely.
CAUTION: Remove the cup when not in use.
MAINTENANCE
Service
Since aging and wear reduce the capacity of the rubber pad, it should be
replaced at least once every 2 years or whenever damage is discovered
(see Inspection).
If the hand cup does not function normally, the cup face may be dirty or
the cup may require service. First clean the cup face according to the
directions to follow. If the condition persists, contact an authorized dealer
or visit
www.crlaurence.com
for assistance.
Cleaning
1) Remove the air filter from the cup face.
2) Use a clean sponge or lint-free cloth to apply soapy water or
another
mild cleanser to the cup face; see WARNINGS and
www.crlaurence.com
for more information. CAUTION: To prevent
liquid from contaminating the pump, hold the cup face-down or cover
the suction hole in the filter recess.
3) Wipe all residue from the cup face.
4) Allow the cup to dry and reinstall the air filter.
Inspection
Examine and test the cup regularly to make sure it does not exhibit the
following faults:
• cuts or damage to sealing edges of rubber pad.
• cracks or dents in handle or pump.
• reappearance of red line soon after attaching cup.
• sluggishness or dramatic changes in pump action.
• excessive glaze or stiffness of rubber pad.
• air filter missing from cup face.
Correct any faults before using the cup (see Service).
Storage
Store the cup in clean, dry condition within its protective carrying case.
WARNINGS
Failure to observe WARNINGS could damage the hand cup or the
load, or cause injury to the user.
• Do not use the cup to lift loads that exceed the Maximum Load
Capacity or the effective capacity (see SPECIFICATIONS).
• Do not use the cup to support a person.
• Do not place the cup face against surfaces which could damage the
sealing edges.
• Avoid conditions that could cause the cup to slip or to disengage
prematurely, such as: contaminants, cuts or scratches in the
cup face; applying the cup to dirty or porous materials; or applying
pressure against the cup edge.
• Do not use the cup to lift when the red line is visible. If the red line
reappears frequently, discontinue use and see Service.
• Do not allow anything to interfere with free movement of the plunger
while the cup is attached.
• Do not touch the valve release lever while lifting.
• Do not use harsh chemicals (such as solvents or gasoline)
or unauthorized rubber cleaners and conditioners to clean the cup.
