(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 IFTER Standard MRTA611LDC pad frame shown. Rev 14.0/5-13 MRTA6-DC: #35072... -
Page 10: To Connect/Disconnect Vacuum Hoses
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 11: To Reposition (Or Remove) Movable Pad Mounts
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 COTTERLESS HITCH PIN with the corresponding holes in the pad frame. -

If necessary, contact Wood's Powr-Grip for help in conducting a friction test. • In order to avoid damaging the vacuum pads, the load's surface temperature must not exceed the allowable Operating Temperatures (see SPECIFICATIONS). However, if such an... -
Page 13: 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 14: 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 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 B30.20 in the USA). -
Page 15: Confirming The Pad Frame Configuration
CAUTION: Examine each air filter regularly, and empty when necessary. Two air filters help protect the vacuum generating system from contaminants. However, the lifter is not intended for use on wet load surfaces because the filters would not prevent liquid from entering the vacuum system. -
Page 16: Reading The Vacuum Gauges
Note: If a vacuum pad has been lying against a hard object (as during shipping), it may be slightly distorted. Although initially it may be difficult to apply the pad to a load, this condition should correct itself with continued use. Reading the Vacuum Gauges The lifter is equipped with 2 vacuum gauges, which indicate the current vacuum level in each green... -
Page 17: About The Tilt Linkage
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, when lifted. -
Page 18: Monitoring Vacuum Indicators
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 19: Controlling The Lifter And Load
Controlling the Lifter and Load When the vacuum indicators show that the lifter is ready, use the hoisting equipment to raise the lifter and load as needed to clear any obstacles in their path. Use the control handle to keep the lifter and load in the desired orientation while they are suspended from the crane. -
Page 20: T O Tilt The Load
ILT THE 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. -
Page 21: After Using The Lifter
FTER SING THE IFTER Leave the valve handle in the “RELEASE” position (power off). CAUTION: Do not set the lifter against any surfaces which could soil or damage the vacuum pads. Use the hoisting equipment to gently lower the lifter onto a stable support; then detach the hoisting equipment hook from the lift spool. -
Page 22: Maintenance
MAINTENANCE WARNING: Always make sure battery is disconnected before servicing lifter. INSTRUCTIONS Note: One or more wiring diagrams are provided in the final section of this manual for reference when servicing the lifter or trouble-shooting a deficiency. NSPECTION CHEDULE Perform inspections routinely, according to the following frequency schedule: Every-Lift Inspection •... -
Page 23: Infrequent Use
• Keep a written record of all Periodic Inspections. If any deficiency is detected during the inspection, correct it before using the lifter. If necessary, return the lifter to Powr-Grip or an authorized dealer for repair (see LIMITED WARRANTY). Infrequent Use each time If a lifter is used less than 1 day in a 2-week period, perform the Periodic Inspection before using the lifter... -
Page 24: Maintenance Schedule
ATTERY ECHARGE Only use a battery charger supplied by or approved by Wood's Powr-Grip; other chargers may reduce battery life. Charge the battery as soon as possible after any extended use of the lifter, or whenever the battery gauge indicates diminished energy (see B preceding). -
Page 25: Attery Harger Est
In addition, all pads should be replaced on a regular basis, preferably after no more than 2 years, to ensure that the friction coefficient is not compromised. If necessary, contact your dealer or Wood's Powr-Grip for more information. Inspection Inspect each vacuum pad for the following deficiencies routinely, as directed in the preceding and T . -
