Lifting bags AS/CR type.
Thin, specific used in industrial machines.

The ha-ka lifting bags of the AS/CR type are manufactured from reinforced NBR rubber hose, equiped with stainless steel or brass air connections. You can choose several different air connections: Vertical, threaded, connections mounted in the hose material, horizontally mounted threaded connections between the end plates, or horizontal air supply hose connections also mounted between the end plates. The lifting bag hose is hermetically closed on both ends with a vulcanising sealing and reinforced with stainless steel end plates.
The lifting bags can be built in compact area’s and are a perfect alternative for short stroke air cilinders.

Applications: Clamping, pressing, brake mechanism, lifting mechanism, conveyor systems, paper industry, food industry, etc.

Characteristics of the AS/CR lifting bags:

• Excelent chemical resistance.
• Abresion resistant.
• Seawater resistant.
• Resistant against aging, UV radiation.
• Maximum working pressure, dependable on the type, 5 to 8 Bar.
• Maximum lifting height (stroke) 115mm.
• Available in every length up to 20 meters, custom built.
• Available in width from 33mm up to 204mm.
• Alowable temperatures for the hose material from -35°C up to +100°C.
• Air connections in stainless steel AISI 303 or brass.
• Endplates made of stainless steel AISI 304.

Applications AS/CR types:

• Lifting.
• Clamping.
• Pressing.

Below you can calculate the force, which your lifting bag can generate.

The force which a lifting bag can generate, is depending on the pressure (P) inside the lifting bag and the effective surface of the lifting bag (L x B). This effective surface will reduce when the stroke (S) of the lifting bag increases.

Instructions:

– At first choose the position of the air connection, horizontal “H” or vertical “V”,
– Choose the width “B” of the lifting bag 33, 44, 55, 65, 85, 105, 125, 165, or 204mm;
– Fill in the length “L” of the lifting bag in mm. This is the total length including the endplates;
– Fill in the working pressure “P” in Bar. The maximum allowable pressure for the chosen type is given;
– Fill in the stroke (S) in mm at which the lifting bag needs to generate the force. This is the lifting distance of the load, calculated from the endplates of the lifting bag, on which the load is resting before inflating the lifting bag. The maximum stroke of the chosen type is given;
– Press the button “Calculate” and you will see the force generated by the lifting bag in Newton and KGf.

Note: There can be small differences between the calculated force and the real force. These differences are dependable on the stroke and will be less than 10%.
