Intelligent Assist Devices vs. traditional lifting equipment

Industrial manipulators INDEVA® (intelligent assist devices) Liftronic® Series vs. traditional lifting equipment and pneumatic manipulators.

The industrial manipulators Liftronic Series better referred to as INDEVAs  (Intelligent Devices for handling) belong to the class of manipulators worldwide known as “Intelligent assist devices (IADs)”. Compared to the traditional pneumatic manipulators, offer significant advantages related to Ergonomics, Safety and Productivity.

Auto-weight sense and automatic load weight balancing.

By means of a  microprocessor based  electronic device the system automatically and instantly balances the load weight; it doesn’t merely  balance the load weight automatically (auto-balancing feature), but it also senses and balances the load weight continually (auto-weight sense feature).  Thanks to this feature the operator can handle that change their weight while being handled (e.g.: drum, cases, bags etc.. being emptied or filled), or loads with different sizes and weights without interrupting  his handling operations for  adjusting load settings or selecting a different pre-set load parameter by means of push buttons or pressure regulators.
The operator can handle loads in a natural and intuitive way almost forgetting he’s using a machine.
Traditional pneumatic controlled manipulators, (including those described as auto-balancing), balance the  load weight  as load is lifted, but do not automatically and continually sense  the load weight and do not automatically adjust balancing as weight varies;
Counter balancing is much slower because it takes much longer for pneumatic signal, to travel around the circuits compared to electronic signal.

High precision in load placing.

The INDEVA® industrial manipulators don’t  over travel, nor bounce and don’t require lots of little corrective movements to reach the required position, as it occurs, instead,  with pneumatic industrial manipulators.

The float mode function (hands on the load) allows operators to perform precision placement tasks with their hands on the load itself for maximum control with no need to use handles or to press buttons; this  mode is very useful especially when load has to be placed in a restricted area or for delicate loads that could be affected by typical bounces of pneumatic control manipulators.

Ergonomic and effortless load handling

With the Indeva Liftronic Series industrial manipulators, the fingertip control mode by means of an in line force sensing handle, provides immediate response to the operator’s moves up and down. This drastically reduces starting, acceleration and deceleration inertia forces, thus allowing the system to operate as an extension of the operator’s arm.  The effort required to the operator for moves along the Z axis is constant and almost null;  this feature, together with their ergonomic design  make the INDEAs the only available material handling solutions that really comply with the strictest regulations and directives on ergonomics and safety in the manual load handling.


Quick movements

 The INDEVA® industrial manipulators respond swiftly, yet smoothly to human touch, winning inertia both during acceleration and braking, amplifying operator movements. The operator notices no time lapse between the machine sensing and its response, which is impossible with pneumatic control manipulators

Greater visibility and ease of maneuverability

Lifting tools used for the INDEVA® industrial manipulators are much lighter and more compact than those used for traditional manipulators and allow for greater visibility and ease of maneuverability.

Versatility

The INDEVA® Industrial Manipulators Liftronic® Easy Series can be equipped with a gripping tool quick coupling device by means of which it is possible to change quickly and easily different end-effectors and handle different types of loads with only a 15 seconds work interruption.
Modifications to load handling parameters or  end-effector functions are very easy to carry out  via electronic software (much simpler operation compared to changing the pneumatic circuits of pneumatic manipulators). This is especially important in case of special end-effectors with multiple functions.
Our modular gripping tool concept “MODULO” and the microprocessor programmable logic make the manipulator LIFTRONIC® Series a unique load handling solution that matches demands in every industry field.
