Model Number: MRTA611LDC Description: Designed for use with a crane or other hoisting equipment, the MRTA611LDC lifter employs vacuum to hold a load for lifting, and it provides manual 360° rotation and mechanically assisted, manual 90° tilt movements for load manipulation.
Page 3 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.
Page 4: Operating Features
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 MRTA611LDC shown. 1 LIFT SPOOL 8 AIR FILTER 15 VACUUM PUMP 2 LIFT BAR...
Page 5 ASSEMBLY ET UP THE IFTER 1) Remove the top of the shipping crate and all devices for restraining the vacuum lifter during shipping. Save the crate 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).
Page 6 HANGE THE RAME ONFIGURATION The lifter offers a variety of pad frame configurations to accommodate different load dimensions and weights (see SPECIFICATIONS: Pad Spread and Load Capacity). The following illustration shows several possible configurations. Select a configuration to provide optimal support across the load surface and to minimize load overhang (see OPERATION: B EFORE SING THE...
Page 7 Configurations are created by installing or removing the pad frame’s extension arms, by repositioning or removing the movable pad mounts, and by connecting or disconnecting the vacuum hoses to certain vacuum pads. Always assemble the pad frame in a symmetrical arrangement, to keep the lifter balanced (see illustration).
Page 8 To Reposition (or Remove) Movable Pad Mounts 1) Remove the cotterless hitch pin from one movable pad mount by pulling on the pull ring. 2) Move the pad mount to the desired position on the pad frame and align the holes for the cotterless hitch pin in the pad mount with COTTERLESS HITCH PIN the corresponding holes in the pad frame.
Page 9: Intended Use
INTENDED USE HARACTERISTICS 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).
Page 10: Operating Environment
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: T : About the Tilt Linkage and T ).
Page 11: Operation
OPERATION EFORE SING THE IFTER The operator must determine whether the lifter is capable of performing each intended task, in INSTRUCTIONS accordance with the SPECIFICATIONS and INTENDED USE sections of this manual. In addition, all of the following preparations must be completed prior to lifting any load. Taking Safety Precautions INSTRUCTIONS WARNINGS...
Page 12 PPLY THE ADS TO A 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: ).
Page 13 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 both vacuum gauges, except when used at high elevations (see SPECIFICATIONS: Operating Elevation). If not, make sure both vacuum switches are adjusted correctly (see MAINTENANCE: V ).
Page 14 IFT AND OVE THE About the Tilt Linkage WARNING: Make sure load is positioned correctly on lifter; unbalanced loads may tilt unexpectedly. The lifter’s tilt linkage is designed to automatically hold a balanced load in either the upright or the flat position. However, an unbalanced load may tilt unexpectedly from the flat position to the upright position or vice versa.
Page 15 Monitoring Vacuum Indicators The low vacuum warning light and both vacuum gauges must remain completely visible to the operator, so that they can be monitored throughout the entire lift. WARNING: Vacuum indicators must be visible to operator throughout entire lift. If the vacuum system experiences leakage while the lifter is attached to the load, the vacuum pump turns on automatically, as required to maintain sufficient vacuum for lifting the maximum load weight.
Page 16 OTATE THE DGEWISE WARNING: Make sure load is positioned correctly on lifter; unbalanced loads may rotate unexpectedly. Remember that the load is longer in its diagonal dimensions than in its side dimensions. Make sure there is sufficient clearance for the load to rotate without contacting the operator or any nearby objects.
Page 17 ELEASE THE ADS FROM THE WARNING: Load must be fully supported before releasing vacuum pads. When the load is at rest and fully supported, pinch the valve release lever against the valve handle, and push the valve handle inward to the “RELEASE” position (power off) until the vacuum pads disengage completely from the load.
Page 18: Maintenance
MAINTENANCE WARNING: Always make sure battery is disconnected before servicing lifter. NSPECTION CHEDULE Perform inspections routinely, according to the following frequency schedule: Every-Lift Inspection • Examine the vacuum pads and load surface for contamination or debris (see V ACUUM to follow). AINTENANCE •...
Page 19 ESTING CHEDULE initially each time following a repair or Perform these tests when placing the lifter in service modification . Correct any deficiency and retest before using the lifter. Operational Tests • Perform the V to follow. ACUUM • Test all features and functions of the lifter (see OPERATING FEATURES, OPERATION and MAINTENANCE).
Page 20: Battery Test
ATTERY The lifter is equipped with a battery gauge to help the operator evaluate whether the battery has adequate energy for lifting. Factors such as the condition of the battery, the time required to execute a lift, and the porosity of the load It is the combine to determine how much battery energy is needed.
Page 21: Battery Charger Test
ATTERY HARGER Perform this test only when the battery is fully charged (see B preceding). While ATTERY disconnected the valve handle is in the “RELEASE” position (power ) and the battery charger is from any AC power source, use the battery test button to take an energy reading on the battery gauge.
Page 22: Vacuum Test
Cleaning Regularly clean the face of each vacuum pad to remove oil, dust and any other contaminates. Acceptable cleaning agents include soapy water, glass cleaner and alcohol. Do use other solvents, petroleum-based products (including kerosene, gasoline and diesel fuel) or any harsh chemicals for cleaning, because they can damage the pad and create a hazard to the operator or others.
Page 23: Air Filter Maintenance
ILTER AINTENANCE (for brass bowl type filters) Filter Function and Conditions Requiring Service An air filter prevents solid particles from contaminating components in the vacuum system. CAUTION: Examine air filter regularly and empty when necessary. Open each filter regularly to determine whether liquid or other contaminants are trapped inside. Remove any liquid or contaminants found in the filter bowl.
Page 24: Vacuum Pump Maintenance
ACUUM AINTENANCE (for Thomas pump nos. 107BA20964, 107BD20964 & 107CDC20) WARNING: Before proceeding with any maintenance, disconnect power source. If the vacuum pump (14) takes too long to attain full vacuum, it may require maintenance. Replace the diaphragm, valve flappers or head gasket as necessary to obtain acceptable pump performance.
Page 25 ACUUM WITCH DJUSTMENT Vacuum Switch Function A vacuum sensor/electrical switch assembly controls the low vacuum warning light and the vacuum pump: The valve handle activates the warning light and the pump, which evacuates the vacuum pads. 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 pump and the warning light.
Page 26 Adjustment Procedure WARNING: Lifting capacity decreases whenever vacuum switch is adjusted to maintain lower vacuum level. 1) Using a 1/4" open-end wrench (as provided), turn the adjustment screw about 1/6th turn at a time (approximately one flat of the screw head). lower clockwise To maintain a...
