KEEP FOR FUTURE REFERENCE INSTRUCTIONS International Version P.O.
SPECIFICATIONS Description: Designed for use with a crane or other hoisting equipment, P1-04AC lifters employ vacuum to hold a load for lifting, and they provide manual 180° rotation and manual 90° tilt movements for load manipulation. Model Number: Vacuum Pads:1 P11004AC P1HV1104AC P11104AC (Four, standard rubber, with #60 filter screen) 10" [25 cm] nom. diameter, 10" [25 cm] nom. diameter, 11" [28 cm] nom.
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. Standard P11104AC shown.
ASSEMBLY 1) Open the shipping container and remove all materials for restraining or protecting the vacuum lifter. Save the container for use whenever the lifter is transported. 2) Suspend the lifter from a crane as follows: Select hoisting equipment (crane and hoist, when applicable) rated to carry the maximum load weight plus the lifter weight (see SPECIFICATIONS: Maximum Load Capacity and Lifter Weight).
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 APPLY THE PADS TO A LOAD Powering up the Lifter With the valve handle in the “RELEASE” position, place the power switch in the "ON" position. This energizes the vacuum pump and the red low vacuum warning light (see Load Capacity and the Warning Light to follow).5 WARNING: Never turn power off during operation; keep pump running throughout lift. The lifter is designed for the vacuum pump to run continuously.
Reading the Vacuum Gauge The vacuum gauge indicates the current vacuum level in the lifter’s vacuum system. The green range indicates vacuum levels sufficient for lifting the maximum load weight, whereas the red range indicates vacuum levels that are not sufficient for lifting the maximum load weight. The gauge needle should show a sudden surge in vacuum as the vacuum pads seal against the load.
TO LIFT AND MOVE THE LOAD Positioning the Lift Bar WARNING: Lift bar must be oriented vertically to lift load. Never lift the load from a flat position with the lift bar latched parallel to the load. Always disengage the tilt latch (see TO TILT THE LOAD to follow) and raise the lift bar to a vertical orientation before attempting to lift. Load Capacity and the Warning Light A lifter's Load Capacity is rated at a vacuum level of 16" Hg [-54 kPa] (see SPECIFICATIONS).
In Case of Power Failure The lifter is equipped with a vacuum reserve tank, designed to maintain vacuum temporarily in case of a failure at the lifter's power source. WARNING: Stay clear of any suspended load in the event of a power failure.
TO TILT THE LOAD WARNING: Never disengage both the rotation latch and the tilt latch at the same time This lifter is not designed for rotation and tilt functions to be used at the same time. Disengaging the rotation and tilt latches simultaneously could cause uncontrolled and unpredictable load movement, potentially resulting in load damage or injury to the operator. CAUTION: Tilt function only works when pad channel is latched in center position of rotation range.
AFTER USING THE LIFTER Leave the valve handle in the “RELEASE” position and place the power switch in the “OFF” position. CAUTION: Do not set the lifter against any surfaces which could soil or damage the vacuum pads. The control handle at the end of the pad channel can be used to support an unloaded lifter when not suspended from a crane: Make sure the pad channel is oriented vertically with the control handle at the bottom.
MAINTENANCE WARNING: Always make sure power source is disconnected before servicing lifter. 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). • Examine the vacuum pads, controls and indicators for visual damage (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.
for cleaning. Do not use unauthorized rubber cleaners or conditioners, such as those intended for cleaning tires or vinyl surfaces, because those products can leave a hazardous film on vacuum pads which significantly reduces their lifting capacity (see Friction Coefficient preceding). The use of any unauthorized cleaning agent is prohibited because it could damage the pad and/or create a hazard to the operator or others. WARNING: Never use solvents, gasoline or other harsh chemicals to clean vacuum pad.
AIR FILTER MAINTENANCE (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. Replace the element if it has an overall dirty appearance, or if there is a noticeable increase in the time required to attain full vacuum.
VACUUM PUMP MAINTENANCE (for Gast pump nos. 3032-101A-G609X and 2032-101-G616X) WARNING: Before proceeding with any maintenance, disconnect power source; allow pump to cool; and vent any vacuum or pressure remaining in vacuum system. If the vacuum pump takes too long to attain full vacuum, it may require maintenance, as directed in the following disassembly/reassembly procedure.
VACUUM SWITCH ADJUSTMENT Vacuum Switch Function A vacuum sensor/electrical switch assembly controls the low vacuum warning light. The power switch activates the warning light and the vacuum pump, which evacuates the vacuum pads.13 After the lifter attains a vacuum level sufficient for lifting the maximum load weight (hereafter, “minimum lifting level”), the vacuum switch automatically turns off the warning light.
