Wood's Powr-Grip MRTALP Series Rotator/Tilter Vacuum Lifters

Wood's Powr-Grip MRTALP Series Low-Profile Rotator/Tilter Vacuum Lifters Intelligent Lifting for Tight Spaces and Heavy Panels

The Wood's Powr-Grip MRTALP Series Rotator/Tilter Vacuum Lifters are heavy-duty, DC-powered vacuum lifting systems engineered for contractors and trades professionals who need precise rotational and tilt control in space-constrained job sites. Available in three specialized models covering insulated metal panels, smooth surfaces (including glass), and flat textured construction materials, this series handles load capacities up to 1,100 lbs (500 kg). Powered by a Dual Vacuum System and equipped with Intelli-Grip® Technology, these lifters are designed for demanding commercial and industrial installation environments.

Unlike standard vacuum lifters, the MRTALP Series features a low-profile design that allows operation in narrow overhead spaces where conventional equipment cannot reach. T-Arms and extension options expand the system's capability to handle long roofing and insulated metal panels, making these lifters a versatile solution across multiple trades rather than a single-use tool.

Key Features & Benefits

Intelli-Grip® Technology with Dual Vacuum System

Intelli-Grip® automatically monitors both vacuum and power systems in real time, maximizing safety and operational efficiency on every lift. The system provides diagnostic codes and on-screen information to simplify maintenance and troubleshooting, reducing downtime on the job. A dual vacuum system ensures redundancy, so a single circuit issue does not immediately compromise load security.

Low-Profile Design for Narrow Spaces

The MRTALP's compact, low-profile frame is purpose-built to operate in tight clearances where standard lifters physically cannot fit — critical for curtain wall installation, interior glazing, and metal panel work in occupied or partially finished structures. Contractors gain access to more installation positions without needing to modify the work environment.

Full Rotator/Tilter Functionality

The lifter provides both rotation and tilt control, allowing operators to precisely orient panels and glass during placement without manual repositioning. This reduces the number of crew members needed for complex installations and significantly decreases the risk of load damage or misalignment.

T-Arms and Extension Options for Long Panels

Pad Frame T-Arm assemblies and long extension arms allow the MRTALP Series to safely handle oversized insulated metal roofing panels that would otherwise be impractical to lift with a standard pad frame. This accessory flexibility means one lifter platform can cover a wider range of panel formats and project types.

Optional Remote Control System (Stock# 59906)

The plug-and-play Remote Control System lets a single operator control all lifter functions from up to 250 feet (76 m) away — ideal for multi-story window and panel installation where the operator and the load are not at the same level. Easy installation requires no special tooling or rewiring.

DC Power for Jobsite Flexibility

All MRTALP Series models run on DC voltage, eliminating the need for an AC power source at the point of use. Battery-powered operation keeps the system functional in locations without reliable electrical access, including rooftops, exterior facades, and remote construction sites.

Common Applications
