Vehicle Recognition Body on Frame Unibody

Unibody Cast magnesium transverse beam behind the instrument panel. Door hinges secured by thick through-bolts located in A- and B-pillars. One-piece hydroformed body side rings. Triple-rolled A-post design resists roof collapse. Shock towers connected solidly to instrument panel. Lateral tie bars that connect the front longitudinal rails were closed to stiffen the front structure and improve crashworthiness. Hydroformed engine cradle ( not shown )

Pneumatic Lifting Bags

Various shapes and sizes Various shapes and sizes High, medium and low pressure High, medium and low pressure

Pneumatic Lifting Bags Plan operation before starting the work Plan operation before starting the work Be familiar with equipment Be familiar with equipment Have an adequate air supply and sufficient cribbing on hand before beginning operations Have an adequate air supply and sufficient cribbing on hand before beginning operations Position bags on or against a solid surface Position bags on or against a solid surface Never inflate bags against sharp objects – use protective mats Never inflate bags against sharp objects – use protective mats Never inflate bags fully unless they are under load Never inflate bags fully unless they are under load Inflate bags slowly and monitor them continuously for any shifting Inflate bags slowly and monitor them continuously for any shifting Never work under a load supported only by lifting bags Never work under a load supported only by lifting bags Do not stand in front of pressurized bags Do not stand in front of pressurized bags

Pneumatic Lifting Bags Shore up the load with enough cribbing to support the load in case of bag failure Shore up the load with enough cribbing to support the load in case of bag failure Interrupt the process frequently to increase cribbing – lift an inch, crib an inch Interrupt the process frequently to increase cribbing – lift an inch, crib an inch Ensure that the top tier is solid when using box cribbing Ensure that the top tier is solid when using box cribbing Avoid exposing bags to materials hotter than 220°F (104°C). Avoid exposing bags to materials hotter than 220°F (104°C). Never stack more than two bags; centre the bags with smaller bag on top and inflate the bottom bag first (½ full), then inflate the top bag fully. Never stack more than two bags; centre the bags with smaller bag on top and inflate the bottom bag first (½ full), then inflate the top bag fully. Stacked bags can only lift the capacity of the lowest rated bag Stacked bags can only lift the capacity of the lowest rated bag

Pneumatic Lifting Bags Max Lifting Capacity: Small – 20.8 US tons or lbs Small – 20.8 US tons or lbs Large – 34.2 US tons or lbs Large – 34.2 US tons or lbs Full of water, Tanker 67 weighs lbs. Is it safe to lift the tanker with our high pressure air bags stacked? Answer: No, call for additional rescue and use two large bags.
