Wood's Powr-Grip MRTA8 Series Rotator/Tilter Vacuum Lifter

Wood's Powr-Grip MRTA8 Series Rotator/Tilter Vacuum Lifter — Heavy-Duty Lifting with Intelli-Grip® Technology

The Wood's Powr-Grip MRTA8 Series is a professional-grade rotator/tilter vacuum lifter designed for contractors and installation professionals handling large, heavy materials such as glass panels, insulated metal panels (IMPs), and other flat or textured surfaces. Available in two configurations — the MRTA811LDC3 for smooth surfaces (up to 1,400 lbs) and the MRTA810TDC3 for textured surfaces (up to 1,200 lbs) — these DC-powered lifters are built for demanding construction and installation environments. The MRTA8 series combines full rotation, quad-axis tilt, and a dual vacuum system to give operators precise, safe control over heavy loads at any stage of the lift.

Unlike conventional vacuum lifters, the MRTA8 series features Intelli-Grip® Technology, which actively monitors vacuum and power systems in real time, automating diagnostics and safety checks that would otherwise require manual intervention. The result is a lifter that is safer to operate, easier to maintain, and more efficient on multi-story and complex installation projects than competing units without integrated monitoring systems.

Key Features & Benefits

Intelli-Grip® Technology

Intelli-Grip® continuously monitors the vacuum and power systems, displaying real-time diagnostic codes and status information so operators can identify issues before they become hazards. It simplifies maintenance and repairs by guiding service personnel through diagnostic procedures, reducing downtime on the job site. This system also supports a mobile app for remote data submission directly to Wood's Powr-Grip for advanced troubleshooting support.

Dual Vacuum System

The MRTA8 series uses a Dual Vacuum System with two independent vacuum circuits (red and green), ensuring that if one circuit experiences a leak or fault, the other maintains holding force on the load. This redundancy is a critical safety feature when lifting high-value or hazardous materials like large glass panels at elevation. Each circuit is individually monitored and displayed via onboard vacuum gauges.

Tilt-Assist

The tilt-assist mechanism allows operators to tilt heavy materials more safely and with less physical effort, reducing operator fatigue and risk of injury during installation. This is especially valuable when setting large panels or glass into frames where precise angular positioning is required. Tilt locks engage and disengage to secure the load at the desired angle during placement.

Movable and Removable Vacuum Pads with Extension Arms

Vacuum pads are repositionable and removable, and the lifter accommodates extension arms to adapt the pad frame configuration to a wide variety of load sizes and shapes. This versatility means contractors can use a single lifter across multiple material types and project sizes without swapping equipment. Pad frame reconfiguration is straightforward and designed for field adjustment.

DC Power with Optional Remote Control

DC power makes the MRTA8 series fully cordless and suitable for use at any elevation or location on a job site without proximity to an AC power source. The optional Remote Control System (Stock# 59906) extends operator control up to 250 ft (76 m), enabling safe, precise operation when installing windows and panels on multi-story buildings from a distance. The remote system uses a plug-and-play connection for fast setup.

Quadra-Tilt Rotation

The MRTA8 series provides full rotation of the load in addition to quad-axis tilt capability, giving operators complete control over load orientation during pick, transport, and placement. Secondary rotation stops can be configured to limit rotation range as required for specific applications. This level of control is essential for complex glazing and panel installation tasks.

Common Applications

Commercial Glazing and Window Installation

The MRTA811LDC3 is ideal for lifting and placing large glass panels, storefronts, and curtain wall units, with smooth-surface pads providing secure adhesion to glass. The optional remote control allows a single operator to guide placement from up to 250 ft away on multi-story facades.

Insulated Metal Panel (IMP) Installation

The MRTA810TDC3 is specifically designed for textured surfaces such as IMPs, providing reliable vacuum adhesion on surfaces that would defeat standard smooth-surface pads. Contractors installing building envelope panels can handle large, heavy sections safely and efficiently.

Multi-Story Building Envelope Work

With DC power and an optional long-range remote control system, the MRTA8 series is well-suited for crane-assisted or aerial lift-based installation of panels and glass at height. The Intelli-Grip® system provides continuous monitoring to maximize safety when the load is elevated.

Prefabricated Panel Placement

The adjustable pad frame and extension arms accommodate a range of prefabricated panel sizes, making the MRTA8 series adaptable to modular construction workflows. Tilt-assist and full rotation allow panels to be oriented precisely for connection to the building structure.

Architectural Glass and Specialty Glazing

For high-value architectural glass applications where surface protection and precise placement are critical, the MRTA8 series provides controlled, damage-free handling. The dual vacuum system's redundancy adds an additional layer of protection for expensive or irreplaceable materials.

Transport and Repositioning of Heavy Flat Materials

On-site material handling of large flat sheets — glass, stone, composite panels — is simplified by the lifter's rotation and tilt capabilities. The optional MRT Dolly (Stock# 98790) allows for easy ground-level transport and storage between lifts.
