  • Page 5: Specifications

    Designed for use with a crane or other hoisting equipment, the MRTALPR4-DC lifters employ vacuum to hold a load for lifting, and they provide manual 180° rotation and mechanically assisted, manual 90° tilt movements for load manipulation. Model Number: MRTALPR4FS625DC MRTALPR4FS10TDC Vacuum Pads: (Four, with #60 filter screen) 6"...

  • Page 9: Assembly

    ASSEMBLY ET UP THE IFTER 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) If necessary, assemble the lifter's lift bar as follows: One segment of the lift bar can be removed, to reduce overall lifter dimensions for shipping.

  • Page 10: T O Install /Remove T-Arm Assemblies

    Note: Some hoisting equipment hooks could interfere with an upright load that extends beyond the lifter's pad frame. If the load would contact the hook during lifter operation, the operator must prevent this by attaching a sling (or other rigging that does not interfere with the load) between the hook and the lift spool.

  • Page 11: To Connect/Disconnect Vacuum Hoses

    To Connect/Disconnect Vacuum Hoses The vacuum hose for each vacuum pad is connected to or disconnected from the lifter's vacuum system by means of a quick connector. To connect the vacuum hose, push the male and female ends of the connector together until they lock. To disconnect the vacuum hose, move the release ring on the female end until the connector separates.

    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 15: 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.

  • Page 16: Preparing To Use The Optional Remote Control System

    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 17: T O Adjust The Pad Frame

    DJUST THE RAME Be sure to adjust the position of vacuum pads and/or cross members of the pad frame T-arm assemblies, so as to optimize load support and minimize load overhang for the intended use. Pads must be arranged symmetrically, to keep the lifter balanced. Note: Use only 2 pads on each T-arm assembly.

  • Page 18: Powering Up The Lifter

    PPLY THE ADS TO A Powering up the Lifter Place the lifter's power switch in the “on” ( ) position. The adjacent, blue power light remains illuminated while the lifter is powered up. Keep the power switch in the “on” position while lifting a load.

  • Page 19: Sealing The Pads Against The Load

    WARNING: Lift point must be adjusted so as to prevent interference between adjustable lift point tube and load. Note: If the load would extend higher than the lift point when lifted or tilted upright, the lift point must be adjusted to prevent interference between the adjustable lift point tube and the load (see ASSEMBLY: T ).
  • Page 20 : Cleaning), and reapply the lifter to the load. If the load has rough or porous AINTENANCE the operator must conduct a test to determine whether the lifter is designed surfaces, to lift the load , as follows: 1) Make sure the lifter's vacuum generating system is functioning correctly (see MAINTENANCE: ACUUM 2) Apply the vacuum pads to the load as previously directed.

  • Page 21: Positioning The Lift Bar

    IFT AND OVE THE 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 T ILT THE follow) and raise the lift bar to a vertical orientation before attempting to lift.

  • Page 22: Monitoring The Low Vacuum Warning Buzzer

    Monitoring the Low Vacuum Warning Buzzer Using the low vacuum warning buzzer requires minimal interaction from the operator. The warning buzzer sounds an alarm until the lifter attains sufficient vacuum to lift the maximum load weight (see SPECIFICATIONS: Load Capacity). After the lifter has attained this vacuum level, the alarm stops sounding, to indicate that the lifter is ready to lift the load.

  • Page 23: T O Rotate The Load Edgewise

    OTATE THE DGEWISE 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.

    ILT THE WARNING: Always keep hands and fingers away from bars of tilt linkage. 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.

  • Page 27: Infrequent Use

    CAUTION: Be sure to use appropriate cleaning methods for each type of electrical component, as specified by codes and standards. Improper cleaning can damage components. • 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 Wood’s Powr-Grip or an authorized dealer for repair (see LIMITED WARRANTY).

  • Page 28: Maintenance Schedule

    AINTENANCE CHEDULE INSTRUCTIONS Unless specified elsewhere in this 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. ATTERY The lifter is equipped with a battery gauge to help the operator evaluate whether the battery has adequate energy for lifting.

  • Page 29: Battery Recharge

    Operating the lifter when the battery charger is connected to an AC power source could result in permanent damage to the charger. 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).

    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. Rev 11.3/1-17...

  • Page 31: Inspection

    Inspection Inspect each vacuum pad for the following deficiencies routinely, as directed in the preceding and T . Correct any deficiency before using the lifter. NSPECTION ESTING CHEDULES • Contaminates on the pad face or sealing edges: Soil build-up can prevent pads from sealing adequately or reduce the friction coefficient (see discussion preceding).

If the vacuum pump takes too long to attain full vacuum, it may require maintenance. Replace the diaphragms, gaskets/flap valves or (when preferable) the entire head assemblies (see REPLACEMENT PARTS LIST), as necessary to obtain acceptable pump performance.

  • Page 36: Vacuum Switch Adjustment

    ACUUM WITCH DJUSTMENT Vacuum Switch Function Two vacuum switches control various functions of the vacuum lifter (see OPERATING FEATURES for location of vacuum switches). While the lifter is powered up, each vacuum switch senses the vacuum level in one of the two vacuum circuits of the vacuum system. If either circuit loses significant vacuum while the lifter is in the apply mode, the system responds automatically.
