Maxi Force Air Bags -20

Question 1

Air bags required how much space for insertion?

Answer 1

1 inch

Question 2

Air Bags for?

Answer 2

• cylindrical /odd shape objects
• collapsed floors, tree, poles
• vehicles, steering column, door post, dashboard
• elevator doors, subway trains, iron bars
• work well with Hurst tool, power saw, torch, air chisel

Question 3

7 bag system..?

Answer 3

smallest- 12-ton bag
largest - 74 ton bag

lifting height — 8” to 20”

tonnage is based on its capacity to lift that tonnage 1 inch…example: 12 ton bag will lift 12 tons 1 inch

74 ton bag will lift 74 tons 1 inch

Question 4

Units should paint?

Answer 4

LIFT HEIGHT AND LIFT CAPACITY

X-used to center bag under load

Question 5

Whenever high pressure air sources is used..?

Answer 5

pressure regulator must be used

Question 6

Air supply hoses?

Answer 6

2- red hoses/16 feet
1-yellow hose/16 feet

-additional hose can be used to allow for safe operation of air bags…all bags, air supply hoses and regulators are equipped with heavy duty quick connectors

Question 7

STEEL scba cylinders are used to operate bags..

Answer 7

Set Low PRESSURE TO 135 PSI

HIGH PRESSURE GAUGE falls below 200 PSI, change the cylinder

always open HIGH pressure air source SLOWLY…make sure all valves are in closed position

Question 8

Control valves?

Answer 8

quarter turn ball valves that work independently

• connect one red air hose to pressure regulator and to the control valve
• connect other red air hose to one of the air outlets

Question 9

Place bag under load with…?

Answer 9

-AIR NIPPLE pointing out
-place bag as close to the load as possible
ALWAYS have the bag connected prior to placing it under or between a load to minimize the operator’s exposure to the load area and to eliminate the possibility of the operator placing the bag with the air inlet under the load

Question 10

Speed of inflation is controlled by?

Answer 10

CONTROL VALVE LEVER- slowly moving it PARALLEL to the air line

-inflate bags SLOWLY to minimize chance of load shifting

Question 11

As bag is being inflated, note the gauge reading on the control valve safety relief. The gauge reads the INTERNAL AIR PRESSURE OF CONNECTED BAG…

Answer 11

MAXIMUM INTERNAL AIR PRESSURE FOR THE BAG WHEN USED FOR LIFTING PURPOSES IS 118 PSI…
-safety relief valve will prevent over inflation

normally inflation should be JUST ENOUGH to lift load as far as needed

when the gauge reaches the vicinity of the RED MARK, safety relief will open (118 psI) and start venting

Question 12

Stabilize and shore load BEFORE placing bags into position…

Answer 12

build shoring as load is being lifted

Question 13

Deflate bag with the control valve safety relief…

Answer 13

close CONTROL LEVERS, then SLOWLY turn the knurled knob on the top of the safety relief counter-clockwise

Question 14

2 separate shut off devices are provided to be used when there is need to inflate several bags..

Answer 14

shut-off device is placed on the NIPPLE of the LIFTING BAG
-as soon as bag is inflated to the required height, knurled knob can be turned clockwise closing off the flow of air to the bag

air hose can now be disconnected and will remain inflated

Question 15

Air cylinders can be changed during operation or when pressure falls below 200 PSI..

Answer 15

change cylinder-stop, block or shore and make sure all inlet and outlet valves on cylinder, pressure regulator and control valve and safety relief are in the FULLY CLOSED POSITION.. disconnect air outlet hose from pressure regulator/disconnect and bleed regulator

Question 16

If necessary to block up bag..?

Answer 16

3/4” plywood, 3 layers thick, glued or nailed or screwed together is recommended

-bags should only be inflated 1/2 to 3/4 of their rated capacity..pillowing affect should be avoided

Question 17

Do NOT stand in front of the opening where the bag has been placed…

Answer 17

there is possibility of the bag being pushed out

Question 18

Never work under a load unless…

Answer 18

it is shored or blocked

-although a bag does not need a smooth surface, blocks or shoring do

Question 19

Avoid inflating bags against..?

Answer 19

SHARP OBJECTS or on a surface heated to over 220 degrees F…
-use insulated pad (canvas/rubber) or 3/4” plywood between hot or sharp surface

Question 20

2 bags may be used safely from ONE CONTROL safety relief device…this allows for greater lift…

Answer 20

NEVER stack more than 2 bags on top of each other and ALWAYS place the smaller bag on top of the larger one

generally-inflate bottom bag first

when stacking- tonnage of SMALLER BAG IS MAX

Question 21

Lifting capability is reduced by 50% to obtain max lifting height…

Answer 21

Example: a 30 tong bag with a max height of 10 inches will lift 30 tons 1 “, but will lift 15 tons 10”

Question 22

Store bags in horizontal position..

Answer 22

do not place wood between bags

Question 23

Leak Sealing Field Kit

Answer 23

seal leaks in tank or truck containers used to store chemical or fuel

• 4 clamps
• 2 ratchet belts, 30 ft
• 2 extension belts, 20 ft
• one air hose, ORANGE, with built in 22 psi safety relief valve…THIS AIR HOSE ONLY USED FOR LEAK SEALING
• 1 sheet neoprene(added bag protection)- 20 inches x 20 inches
• slowly inflated- stop when leak is stopped or relief valve is venting- do not override
• do not be concerned if the teeth clamps ‘bite’

Question 24

Inspect?

Answer 24

before each use/after each use

• never drag bag by hoses
• average life of bag is 10 years
• wash with soap and water
