Mounted to the bracket is a 5-way pneumatics valve that is de-actuated by the position flag as the balancer travels upward. The external retract control is an adjustable safety feature that regulates the balancer's speed of vertical travel. The external retract control puts resistance on the thrust bearing allowing the cable or chain to slowly retract into the air balancer to ensure that any runaway load comes to an immediate and complete halt. When specifying a pneumatic balancer, it is recommended for working loads to use 80% of the operating capacity for lifting applications. This approach compensates for the normal fluctuations within the plant compressed air supply. Working loads include part weight and handling device weight. Balancers are rated at 100 psi [6.8bar] therefore use the following example to calculate exact operating capability.\u003c\/p\u003e\u003cp\u003eFormula for pneumatic balancer sizing: Example - plant air 60 psi, 350 air balancer, 80% load capability (0.60 air supply x 350 lbs. = 210 x .80 = 168 lbs. operating capability)\u003c\/p\u003e\u003ch2\u003eFeatures:\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCE Compliant\u003c\/li\u003e\n\u003cli\u003eHands-Free Operation\u003c\/li\u003e\n\u003cli\u003eStandard \"Float\" Mode\u003c\/li\u003e\n\u003cli\u003eRequires Non-Lubricated Clean\/Dry Air\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eBenefits:\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eOptional High Relieving and Feather touch Controls\u003c\/li\u003e\n\u003cli\u003eMultiple Suspension Kits Available\u003c\/li\u003e\n\u003cli\u003eWhen ordering, specify * LS1 or LS2 for (1) Limit Switch or (2) Limit Switches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSpecifications:\u003c\/h2\u003e\u003cstyle\u003etable, th, td {border: 1px solid black; border-collapse: collapse;}td {text-align: center;}\u003c\/style\u003e\u003ctable style=\"width:50%\"\u003e\n\u003ctr\u003e\n\u003cth\u003eModel Number\u003c\/th\u003e\n\u003cth\u003eRated Capacity lbs.
