Abstract
A drop table can provide optimized lifting operations by employing motor feedback to generate and adapt a lifting strategy that controls lifting parameters. A lifting module may be connected to a first motor and consist of a lifting controller. The first motor can be mechanically coupled to a first lifting column by a first transmission and to a second lifting column by a second transmission. A service component can be lowered with the first and second lifting columns by activating the first motor that provides motor feedback. A lifting strategy can be generated in response to the motor feedback and subsequently executed to move the service component to a servicing position.
Claims20
An apparatus comprising a lifting module connected to a first motor and comprising a lifting controller, the first motor mechanically coupled to a first lifting column by a first transmission and to a second lifting column by a second transmission, the lifting controller configured to generate a lifting strategy in response to feedback from the first motor.
A method comprising:
- connecting a lifting module a first motor, the lifting module comprising a lifting controller, the first motor mechanically coupled to a first lifting column by a first transmission and to a second lifting column by a second transmission;
- lowering a service component with the first and second lifting columns by activating the first motor;
- detecting a weight of the service component with the lifting module in response to feedback from the first motor;
- and
- generating a lifting strategy with the lifting controller in response to the feedback of the first motor.
A method comprising:
- connecting a lifting module a first motor, the lifting module comprising a lifting controller, the first motor mechanically coupled to a first lifting column by a first transmission and to a second lifting column by a second transmission;
- lowering a service component with the first and second lifting columns by activating the first motor;
- generating a lifting strategy with the lifting controller in response to the feedback from the first motor;
- executing the lifting strategy to move the service component to a servicing position;
- detecting a deviation in lifting parameters expected in the lifting strategy;
- and
- altering the lifting strategy to correct the detected deviation.
