SPECIFICATIONS Description: Model Number: Designed for use with a crane or other hoisting equipment, MTA4LP6FAC and MTA6LP6FAC lifters employ vacuum to hold a load for lifting, and they provide mechanically assisted, manual 90° tilt movements for load manipulation. MTA4LP6FAC (w/4 pads) MTA6LP6FAC (w/6 pads) Lifter Weight: 48 lbs [22 kg] 55 lbs [25 kg] Maximum Load Capacity: 200 lbs [90 kg] 300 lbs [135 kg] (based on Per-Pad Load Capacity of 50 lbs [22.
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 MTA6LP6FAC shown. Rev 16.
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.
Conversely, allowable thickness increases as load weight decreases. In addition, an operator may be able to manually counteract the tendency of unstable loads to tilt out of the upright position, provided that the operator maintains control of the load at all times (see OPERATION: TO LIFT AND MOVE THE LOAD: About the Tilt Linkage and TO TILT THE LOAD). If necessary, contact Wood’s Powr-Grip for help in determining the maximum thickness permitted when handling any specific load.
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 Generating Vacuum Flow Place the power switch in the "ON" position. This engages the vacuum pump, causing vacuum to be drawn immediately at the vacuum pads. WARNING: Never turn power off during operation; keep pump running throughout lift. The lifter is designed for the vacuum pump to run continuously.
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.
Load Capacity and the Vacuum Gauge A 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].
TO TILT THE LOAD WARNING: Always keep hands and fingers away from bars of tilt linkage. Remember that the load requires more vertical space when tilted to the upright position, as well as more horizontal space when tilted to the flat position. Make sure there is sufficient clearance for the load to tilt without contacting the operator or any nearby objects. Lift upward or press downward on the control handle to tilt the load as desired.
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.
