Wood's Powr-Grip MRTALPCH Series Panel Channel Plus Lifter Low-Profile Vacuum Lifting for Glass & Panel Installation

The Wood's Powr-Grip MRTALPCH Series Panel Channel Plus Lifter is a professional-grade, DC-powered vacuum panel lifter engineered for contractors and glazing professionals who need reliable lifting performance in confined or tight spaces. Available in two configurations—Stock #98738 (MRTALPCH611LDC3) for flat, smooth glass up to 1,100 lbs (500 kg), and Stock #98736 (MRTALPCH610TDC3) for textured surfaces, Insulated Metal Panels, and Cold Storage Panels up to 900 lbs (410 kg)—this lifter covers a broad range of panel and glazing applications. Its channel-style, low-profile design allows it to operate in narrow spaces where conventional lifters cannot fit, making it a practical choice for complex installation environments.

Unlike standard vacuum lifters, the MRTALPCH Series is equipped with Intelli-Grip® Technology, which actively monitors vacuum and power systems in real time to maximize safety and operational efficiency while simplifying maintenance and diagnostics. The dual vacuum system provides redundant holding security, and the optional Remote Control System (Stock #59906) extends operational range up to 250 ft (76 m), enabling single-operator installation on multi-story buildings. An optional Adaptor Kit (Stock #57326) allows VPFS10T Pads to be installed for expanded Insulated Metal Panel handling capability.

Key Features & Benefits

Intelli-Grip® Technology

Intelli-Grip® continuously monitors both the vacuum and power systems, displaying diagnostic codes and operational data to keep the operator informed at all times. This automated monitoring reduces the risk of undetected vacuum loss and streamlines troubleshooting and maintenance, lowering downtime on the job site. The system is compatible with a mobile app for submitting lifter data directly to Wood's Powr-Grip for remote support.

Dual Vacuum System

The dual vacuum circuit design provides two independent vacuum paths, so if one circuit experiences a leak or fault, the other continues to hold the load securely. This redundancy is critical when lifting large glass panels or heavy cold storage and insulated metal panels where load drops are unacceptable. The system also features a vacuum reserve tank to maintain holding pressure during pump cycling.

Low-Profile Channel Design

The MRTALPCH Series uses a channel-style frame based on Wood's Powr-Grip's proven P1 Lifter Series architecture, purpose-built with a low-profile geometry that allows it to fit into narrow gaps and tight installation zones. Contractors working in curtain wall, storefront, and panel installation applications frequently encounter clearance limitations that this design directly addresses. The configurable pad frame also supports extensions for varying load sizes.

Manual Rotator / Tilter

An integrated manual rotator and tilter allows the operator to reposition and angle loads precisely during installation without removing the lifter from the panel. This is essential for setting glass into frames, aligning panel seams, and achieving correct orientation in curtain wall and panel installation. The tilt linkage and rotation release lever are operator-accessible from the control handle.

Optional Remote Control System (Stock #59906)

The plug-and-play Remote Control System provides wireless operation of all lifter functions from up to 250 ft (76 m) away, enabling a single operator to safely manage lifts on multi-story buildings without a second ground-level crew member. Installation is straightforward with no special wiring required. This option is particularly valuable for window and curtain wall installation on high-rise structures.

Configurable Pad System with Adaptor Kit Option (Stock #57326)

The optional Adaptor Kit for VPFS10T Pads allows the lifter to be reconfigured for Insulated Metal Panel handling, extending the utility of the same base lifter across glass and panel scopes of work. Pad frame extensions can be installed or removed in the field to accommodate different load dimensions. This modularity reduces the need for multiple specialized lifters on a single project.
