MatJack Inflatable Jacks - Single Bag - 70psi
Steel-Mesh Construction: Matjacks inflatable lifting bag jacks are constructed from heavy duty rubber with three layers of woven steel mesh per side making the bags extremely robust and durable.
Manufacturer: MatJack | Country of Origin: USA
Features: These industrial inflatable lifting bags offer the following capabilities:
- Bull’s Eye: A clearly marked 'bull's eye' on each lifting bag jack allows for quick centering under the load.
- Rating Displayed: Each lifting bag displays the tonnage rating in large numbers for easy identification.
- Anti-Slip: The anti-slip rubber outer surface prevents the bag from shifting.
- Stackable: Each Matjack bag is outfitted with conical interlocking surface providing the ability to stack one bag on top of another (up to two bags) for extra lift-height.
- Dimensions: These inflatable lifting jacks come in different capacities and shapes to accommodate various applications.
- Ground conditions: The tough exterior of the bag enables use on hard or soft surfaces.
- Weather conditions: These lifting jacks can also be used in all weather conditions.
- Resistant: The material is resistant to abrasions, punctures, tears, and withstands many gases and chemicals, both petroleum and water based.
Includes: (1) one bag.
WARNING: Never exceed rated capacity!
Optional Accessories:
- Single Control Box: Controls the advance, hold, and retracting of the air bag - Outfitted with pressure gauge and relief valve
- Double Control Box: Allows for independent or simultaneous operation of one or two air bags - Outfitted with pressure gauge and relief valve
- Shut-Off Valve: Manually shuts off air intake to inflated bag
- Air Supply Hose: Connects the control box to the air bag

Product Education

MatJack inflatable lifting bag jacks are widely used in lifting and relocating of industrial machinery, cargo, heavy objects, rigging, lift truck service, and moving shipyard equipment.
Selection Criteria 1: Application
Using ONE or MULTIPLE inflatable jacks
All MatJack inflatable jacks are made to work with your existing system. Outfitted with 1/4in universal quick connectors, mix and match bags and components with your own.
The inflatable lifting jacks have a conical rubber anti-slip surface to interlock when stacked. Bags are made for stacking to fill-in large voids and achieve more lift. Bags can also be used side-by-side with as many bags as needed for synchronous lifting.

If using two or more inflatable jacks side-by-side: Capacity is increased with each additional bag as long as the load weight is evenly distributed, and each lifting bag carries the same amount of weight.


Stacking two air bags is used to fill a void, providing a practical alternative to cribbing. Additionally, stacking increases the lift height.
Note: Never stack more than two bags!

Selection Criteria 2: Space
Bag Shapes & Sizes
Inflatable lifting jacks can be used flat on the ground as well as cribbed, horizontal or vertical in a niche. The shape of the air bags vary with capacity. This provides choice to accomodate various sized spaces.
Each bag is outfitted with a diagonal connection nipple to allow inflatable bags to be rotated and use longways or sideways.

Selection Criteria 3: Capacity
Capacity Decreases with Lift Height
Lift capacity is dependent on the effective contact area. When the inflatable bag is flat, it has the largest surface contact area with the floor and the load. As the bag is inflated, taking the shape of a balloon, the surface contact area decreases, reducing the lift capacity. See graphic below.
When selecting an inflatable jack, it may be helpful to expect the following actual performance in the field:
RULE-OF-THUMB
50% Capacity at
50% the Lift Height
The ‘50/50 rule’ applies to inflatable jack air bags: The bag will deliver 50% of the capacity at 50% of the maximum lift height. To increase total capacity, consider using multiple bags side-by-side. To increase lift height, consider cribbing or stacking two bags.

How to connect the system
Inflatable
air jacks may be used on the ground, as well as cribbed or blocked.
Single or double control boxes may be connected to the inflatable jacks
for (1) one or (2) two bag operating systems. The control box activates
inflation and deflation and is outfitted with an air pressure gauge and
relief valve. The manual shut-off valve stops air intake and holds the
bag inflated.
Accessories needed to operate an inflatable jack:
- Single Control Box: Controls the advance, hold, and retracting of the air bag - Outfitted with pressure gauge and relief valve.
- Double Control Box: Allows for independent or simultaneous operation of one or two air bags - Outfitted with pressure gauge and relief valve.
- Shut-Off Valve: Manually shuts off air intake to inflated bag.
- Air Supply Hose: Connects the control box to the air bag.
All lifting bags and components are outfitted with the same male and female 1/4in quick connectors.


Avoiding Point-Loading
Consider
using a plate between the load and the inflatable bag if the load contact surface
is not flat. Not only will this protect the inflatable jack against point loading,
but it will also provide a larger surface contact area to deliver a
higher lift capacity.

Understanding Inflatable Lifting Jacks
Intro:
Inflatable jacks are industrial balloons used for lifting heavy objects
or structures by using compressed air or water to expand a
flexible membrane, made of strong, durable reinforced aramid fabric. These air bags are commonly used in situations where traditional mechanical jacks
are impractical or unavailable. Inflatable jacks are valued for their
portability, versatility, and ease of use, making them suitable for a
wide range of applications, including vehicle recovery, structural
repairs, and emergency response situations. These lifting bags come in various sizes
and lifting capacities to accommodate different needs and scenarios.
Application: Inflate bags with an air compressor, portable air tank or other shop air to raise heavy loads. Designed for lifting of machines, cargo, heavy objects, rigging, lift truck service, relocating industrial machinery, and moving shipyard equipment.
Description: Due to their multi-layer construction including steel mesh, MatJack lifting bags are extremely robust to withstand ehavy duty industrial applications. The material will stand up to abrasions, punctures, tears, and resists many gases and chemicals, both petroleum and water based. The large anti-slip exterior of the bag enables use on hard or soft surfaces such as grass or sand. Each bag is clearly marked with capacity and other important safety information.
