SPECIFICATIONS Model Number: PT10FS10TAIR(O) or PT14FS10TAIRO Description: Designed for use with a crane or other hoisting equipment, all variations of the PT10FS10TAIR lifter employ vacuum to hold a load for lifting, and they provide powered 90° tilt movement for load manipulation.
WARNINGS Powr-Grip is pleased to offer the most reliable vacuum lifters available. Despite the high degree of security provided by this product, certain precautions must be observed to protect the operator and others. Always wear personal protective equipment that is appropriate for the material being handled. Follow trade association guidelines. Always operate the lifter under conditions approved for its design (see INTENDED USE: OPERATING ENVIRONMENT).
OPERATING FEATURES Note: Components featured in the following instructions for assembling, operating or maintaining the vacuum lifter are underlined on their first appearance in each section. Note: PT10HV11FAIR shown; see SPECIFICATIONS for correct Pad Spread.
ASSEMBLY 1) Open the shipping container and remove all materials for restraining or protecting the vacuum lifter. Save the container for use whenever lifter is transported. 2) Connect the lifter to an appropriate compressed air supply (see SPECIFICATIONS: Power Source), as follows: Install the female quick connector (supplied) on the compressed air line. Connect the female quick connector to the male quick connector leading directly to the air supply valve.
INTENDED USE LOAD CHARACTERISTICS WARNING: This lifter is NOT intended for lifting hazardous materials, such as explosives or radioactive substances. The operator must verify that the lifter is intended to handle each load, in accordance with the following requirements: • The load must not exceed the maximum allowable weight specified under Load Capacity (see SPECIFICATIONS). • The load must be a single piece of nonporous or semiporous material with a flat and relatively smooth contact surface.
OPERATING ENVIRONMENT The operator must determine whether the lifter is intended to be used in each work environment, in accordance with the following restrictions: WARNING: Never use lifter in dangerous environments. • This lifter is not intended for use in any environment that is inherently dangerous to the operator or likely to compromise the lifter's ability to function. Environments containing explosives, caustic chemicals and other dangerous substances must be avoided when using the lifter.
OPERATION BEFORE USING THE LIFTER The operator must determine whether the lifter is capable of performing each intended task, in accordance with the SPECIFICATIONS and INTENDED USE sections of this INSTRUCTIONS manual. In addition, all of the following preparations must be completed prior to lifting any load. Taking Safety Precautions The operator must be trained in all relevant industry and regulatory standards for the operation of the vacuum lifter in its geographical location (eg, ASME B30.
TO USE PAD SHUTOFFS Each shutoff on the pad frame controls the vacuum line to the adjacent vacuum pad. By activating or deactivating the vacuum flow at specific pads, the operator can use the lifter to handle loads of various weights and dimensions (see Load Capacity and Pad Spread in SPECIFICATIONS). In addition, certain pads may be deactivated in order to avoid holes in the load surface.
Positioning the Lifter on the Load Make certain that the contact surfaces of the load and all vacuum pads are free of any contaminates that could prevent the pads from sealing against the load (see MAINTENANCE: VACUUM PAD MAINTENANCE). Center the lifter’s pad frame to within 2" [5 cm] of the load center, since off-center loading can interfere with the lifter’s tilt capability (see TO TILT THE LOAD to follow), and it may also damage the lifter.
Vacuum Level on Optimal Surfaces When the lifter is attached to clean, smooth, nonporous load surfaces, it should be able to maintain a vacuum level in the green range on the vacuum gauge, except when used at high elevations (see SPECIFICATIONS: Operating Elevation). If not, perform the VACUUM TEST (see MAINTENANCE) to determine whether there is a deficiency in the vacuum generating system.
TO LIFT AND MOVE THE LOAD WARNING: Lift bar must be oriented vertically to lift load. Load Capacity and the Vacuum Gauge The lifter's Load Capacity is rated at a vacuum level of 16" Hg [-54 kPa] (see SPECIFICATIONS). Vacuum higher than this level registers in the green range on the vacuum gauge, to indicate that the lifter is ready to lift the maximum load weight. WARNING: Never attempt to lift load unless vacuum level registers higher than 16” Hg [-54 kPa].
Controlling the Lifter and Load When the vacuum gauge shows that the lifter is ready, use the hoisting equipment to raise the lifter and load as needed to clear any obstacles in their path. Note: The hang angle of the lifter may shift suddenly upon lifting or releasing the load; the operator should anticipate and compensate for such changes. Use the control handle to keep the lifter and load in the desired orientation while they are suspended from the crane.
TO RELEASE THE PADS FROM THE LOAD WARNING: Load must be fully supported before releasing vacuum pads. When the load is at rest and fully supported, move the lever on the vacuum control valve to the "RELEASE" position: Pull outward on the lever's knob, move the lever all the way downward and then release it. This forces air into the vacuum pads, quickly breaking the vacuum seal. After the pads have disengaged completely from the load, move the lifter away.
MAINTENANCE WARNING: Make sure power source is disconnected before servicing lifter. Note: One or more wiring/hose routing diagrams may be provided in the final section of this INSTRUCTIONS manual for reference when servicing the lifter or trouble-shooting a deficiency. INSPECTION SCHEDULE Perform inspections routinely, according to the following frequency schedule: Every-Lift Inspection • Examine the vacuum pads and load surface for contamination or debris (see VACUUM PAD MAINTENANCE to follow).
If any deficiency is detected during the inspection, correct it before using the lifter. If necessary, return the lifter to Wood’s Powr-Grip or an authorized dealer for repair (see LIMITED WARRANTY). Infrequent Use If a lifter is used less than 1 day in a 2-week period, perform the Periodic Inspection each time before using the lifter. TESTING SCHEDULE Perform these tests when placing the lifter in service initially and each time following a repair or modification.
MAINTENANCE SCHEDULE Unless specified elsewhere in this INSTRUCTIONS manual, the lifter does not require maintenance on a routine basis. Instead, maintenance must be performed whenever a deficiency is indicated by routine inspections or tests. Any maintenance warranted must be performed before resuming normal operation of the lifter.
Cleaning Regularly clean the face of each vacuum pad to remove oil, dust and any other contaminates. Acceptable cleaning agents include soapy water and other mild cleansers. Do not use solvents, petroleum-based products (including kerosene, gasoline and diesel fuel) or any harsh chemicals for cleaning.
TILT COMPONENTS MAINTENANCE Tilt Actuator Tilt motion is accomplished using an air-powered linear actuator. Since the tilt actuator is prelubricated, no additional lubrication is required under normal circumstances. The tilt actuator is equipped with several adjustable features that are set at the factory and should not need readjustment.
indication it has come out of adjustment. The standard setting for the master valve is 2 turns counter-clockwise from full clockwise, when viewed from the end of the adjustment knob. The master valve must remain at the standard setting and should not be adjusted, unless there is reason to believe that it has come out of adjustment. TO REPLACE FOAM RING INSERT IN VACUUM PAD 1) Remove the old foam ring insert: Hold the vacuum pad firmly and pull the ring insert out from the mounting groove.
AIR FILTER MAINTENANCE − LARGE (for 4.4 oz [130 ml] bowl size filters) Filter Function and Conditions Requiring Service An air filter prevents solid particles and liquid from contaminating components in the vacuum system. CAUTION: Examine air filter regularly and empty when necessary. Liquid must not contact any portion of the filter element; remove trapped liquid regularly.
AIR FILTER MAINTENANCE − SMALL (for 1 oz [30 ml] bowl size filters) Filter Function and Conditions Requiring Service An air filter prevents solid particles and liquid from contaminating components in the vacuum system. CAUTION: Examine air filter regularly and empty when necessary. Liquid must not contact any portion of the filter element; remove trapped liquid regularly.
