Product
Description
Designed for use with hoisting equipment, the MRPT89AC lifter supports loads using vacuum and
manipulates loads using manual 360° rotation and powered 90° tilt motions.
Model Number MRPT89AC(O)
Vacuum Pads1
1...... Available with other rubber compounds for special purposes (see wpg.com).
(8 each, standard rubber) 9" [23 cm] nominal diameter (Model VPFS9)
Maximum Pad Spread
(to outer edges) 29¼" x 59¼" [75 cm x 151 cm] w/standard pad frame (see “Product Options” below)
Maximum Load
Capacity2
2...... The Maximum Load Capacity is rated at a vacuum of 16" Hg [-54 kPa] on clean, smooth, nonporous flat surfaces with a friction coefficient of 1. Pad
compound, load rigidity, strength, surface conditions, overhang, angle, center of gravity and temperature can also affect the lifting capacity. A “qualified
person” should evaluate the effective lifting capacity for each use (see definition under “Rated Load Test”).
Per-Pad: 125 lbs [57 kg]
Total: 1000 lbs [455 kg]
Lifter
Weight 278 lbs [126 kg]3
3...... Does not include options; see serial label for lifter weight including options, when applicable.
