Regarding industrial ergonomic lifts, there are really only two types to consider, intelligent lifting devices and air balancer.

Firstly, most widely used in industry, consumers know the difference between intelligent hoists and air balancer.

1st Intelligent hoist is controlled by PLC, servo-driven rise encoder feedback. This typically has a lift load near the ropes that sends feedback PLC giving rise immediate response to actions of the operator. Load cell has the ability to lift weight to give a reading in some other programmable features.

2nd The air balancer is strictly air powered hoists without intelligent features at all. The hoist consists of an air cylinder with a piston and drum. The piston is driven compressed air is controlled by a pendant to the operator's hand. Pendant with up / down controls that allow the operator speed control. In fact, the opening and closing the valve. Harder you press, another valve opens, and the faster will moving hoist.

Lets break the lift based on three main criteria, control, speed and special characters.

Control --

Smart lift and air balancer both have variable speed control, which means that the elevator will move at depending on the entry. So even if they are similar in their basic functions, which are very different in terms of actual accuracy.

Intelligent hoist immediately sends the signal back to the elevator and control engine provides immediate feedback operator input. This allows the hoist to accelerate and decelerate quickly, and stop on a dime if need be. Check air balancer is much less accurate, and the flag will tend to repel at standstill due to the nature of compressed air.

Speed --

Both units have a very fast high-end speed, which is usually much faster than typical air or electric hoist. Smart rise speeds to 275 fpm at 150 pounds capacity range, while the air balancer top end speed is usually in the range of 150 FPM.

Air balancers usually come with a posted top end speed, it varies depending on air pressure and flow. If your device air pressure is less than 100 dogs, not only not a good high end speed, but you will have the full capacity of the lift well.

Special Features --

Special features for intelligent hoist is where does the money when comparing the two products. An intelligent hoist is typically $ 7,500 and air balancer is usually around $ 2,500, this is the place where you make the decision. As the above two functions are somewhat similar, such lifts differ greatly in terms of special functions.

1st Air balancer It has no special properties, and is limited by the ability to set their own pneumatic. Even if you can do to lift the little smarter by adding following self-monitoring and pressure sensors, are still subject to variables of your business air. So what you see is that you can get a quick lift, with a higher average accuracy at a lower price.

2nd Intelligent hoist is loaded own functions, which may lift some applications much easier to perform. The first feature to float mode. This allows the operator to press button and no load virtually weightless. We could handle up to 165 lbs load with only your pinky finger. It is ideal when the operator is loading expensive or inappropriate parts to accessories.

second feature the unit is to set up the virtual limit. Intelligent hoist allows the operator to set the upper body speed reduction, lower points reduction in the speed and the upper and lower stop points. This allows the operator to use to pick up speed without having to worry about damage to the product a specified location.

Last feature would be to flag the output information. The unit has digital outputs, allowing tie to lift the assembly line. These outputs provide customers the ability to monitor the weight lifted, off the conveyor and select the zone for lifting. Therefore, if you can program, you can control the unit.

So now you know the difference, and you can decide what is tackling right for you.
