Wood’s Powr-Grip MT2HV11AIR Compressed Air Vacuum Lifter 300 lb Full-Capacity Vertical & Flat Lifting
The Wood’s Powr-Grip MT2HV11AIR is a compressed-air-powered vacuum lifter rated for 300 lbs (135 kg) in both vertical and flat lifting orientations, engineered for ergonomic single-operator handling of heavy loads on the job site. Designed for trades professionals and contractors, it eliminates the need for two-person lifts and reduces the risk of strain injuries when positioning large panels, glass, stone, or similar materials. The compressed air power source makes it well-suited for job sites where a shop air supply is readily available and battery charging or AC power access is limited or inconvenient. This is a full-capacity MT2-series model, delivering rated load performance in all lifting modesnot just flat.
Unlike the MT1-series models which are limited to 150 lbs (70 kg) in vertical orientation, the MT2HV11AIR maintains its full 300 lb (135 kg) rated capacity regardless of whether the load is lifted flat or tilted to vertical, making it the more capable choice for demanding applications that require frequent repositioning of heavy materials. Its compressed air power system eliminates battery management concerns entirely and provides continuous operation as long as an air supply is connected.
Key Features & Benefits
Full 300 lb Capacity in Vertical and Flat Modes
The MT2HV11AIR is rated at 300 lbs (135 kg) for both vertical and flat lifting, giving contractors full-load capability no matter how the material is oriented. This removes the need to downgrade operations or use a secondary lift assist when tilting heavy panels into position. Competing MT1-series units drop to 150 lbs (70 kg) in vertical mode.
Compressed Air Power Source
Powered by a standard compressed air supply, this lifter is ideal for job sites with readily available shop air and eliminates the downtime associated with battery charging or the infrastructure requirements of AC power. The air-powered system provides consistent, reliable vacuum generation as long as supply pressure is maintained.
Manual Tilt Function
The integrated manual tilter allows a single operator to reposition loads from flat to verticalor any angle in betweenwithout setting the load down or recruiting additional personnel. This is critical for installing wall panels, curtain glass, or countertops where orientation changes are part of the normal workflow.
Single-Operator Ergonomic Design
The lifter is purpose-built to allow one person to safely handle heavy, awkward loads that would otherwise require a crew. Dual control handles, vacuum gauges, and warning indicators keep the operator informed of load status throughout the lift. This directly reduces labor costs and minimizes the risk of musculoskeletal injury on site.
Vacuum Monitoring and Warning System
Built-in vacuum gauge, low-vacuum warning light, and audible warning buzzer provide continuous feedback on pad seal integrity during operation. If vacuum drops to an unsafe level, the operator is immediately alerted before load integrity is compromised. This safety architecture is essential for overhead or elevated lifts where a sudden release could cause serious injury or damage.
Robust, Field-Serviceable Construction
The lifter is designed for field inspection, testing, and maintenance by skilled technicians using the published service manual. Replaceable air filter elements, vacuum pump diaphragms, and head assemblies mean the unit can be kept in service with standard servicing rather than full replacement. Wood’s Powr-Grip publishes comprehensive operating instructions, service manuals, and troubleshooting guides to support ongoing maintenance.
Common Applications
Large-Format Glass and Glazing Installation
Ideal for setting curtain wall panels, storefront glass, and architectural glazing where precise positioning and controlled tilting from flat to vertical is required by a single glazier.
Stone and Tile Countertop Setting
Allows one installer to lift and position heavy granite, quartz, or marble countertop slabs without a full crew, reducing labor cost and improving placement accuracy.
Composite and Fiber Cement Panel Installation
Handles large, heavy cladding panels on commercial and residential facades, enabling a single operator to maneuver panels into place at height with full control.
Precast Concrete Panel Handling
Suitable for moving and positioning smooth-faced precast concrete elements in manufacturing, tilt-up, or installation environments where surface integrity must be maintained.
Solid Surface and Engineered Stone Fabrication
Used in fabrication shops to safely rotate, reposition, and transport heavy stone or solid surface workpieces between workstations without mechanical handling damage.
General Heavy Panel and Board Handling
Applicable to any job site or shop environment where single-operator ergonomic handling of flat, non-porous heavy loads is required, including metal sheets, laminated panels, and similar materials.

Application Instructions
Before Using the Lifter
- Read and understand the full operating instructions before operating the equipment.
- Connect the lifter to a suitable compressed air supply meeting the manufacturer’s pressure requirements.
- Perform all pre-use inspections per the inspection schedule in the operating instructions.
- Conduct a lifter/load compatibility test and vacuum test before lifting any rated load.
- Verify the vacuum gauge reads correctly and that the warning light and buzzer are functional.
Attaching the Lifter to a Load
- Position the lifter squarely on the load surface, ensuring all vacuum pads contact the material fully.
- Activate the vacuum system and allow it to reach full vacuum.
- Read the vacuum gauge to confirm adequate seal before attempting to lift.
- If the low-vacuum warning light or buzzer activates, do not liftreposition pads and re-seal.
Lifting, Moving, and Tilting the Load
- Use both control handles to maintain control of the lifter and load throughout the move.
- Monitor vacuum indicators continuously during the lift and move.
- To tilt the load, engage the tilt release lever and rotate the load to the desired angle.
- Never exceed the rated load capacity of 300 lbs (135 kg) in any lifting orientation.
- In case of power failure, follow the emergency procedures outlined in the operating instructions before attempting to release the load.
Releasing and Storing the Lifter
- Set the load down on a stable surface before releasing vacuum.
- Release vacuum and confirm the load is fully supported independently before removing the lifter.
- Disconnect from the air supply after use.
- Inspect pads and all components after each use per the maintenance schedule.
- Store the lifter per the storage instructions in the operating manual.
