Description
Gravity Ant – intelligent electric lifting manipulator
Gravity Ant is a fast and ergonomic electric lifting manipulator for repetitive lifting, moving and assembly work. The servo-driven device follows the operator’s movement precisely and allows light handling of the load without constantly pressing the buttons of a conventional hoist.
Gravity Ant is especially suited to production, assembly, machining, packing and other work stages where loads are handled frequently and precise positioning is important.
Lifting capacity 50–300 kg – lifting height up to 3 metres – reach up to 5 metres.
More than an ordinary hoist
Gravity Ant combines the features of a hoist, a balancer and a manipulator. Its stepless speed control responds naturally to the operator’s movements, so lifting, lowering and positioning the load is fast and controlled.
In Float Mode the load can be brought to an almost weightless state. The operator can then move the load up and down by guiding the load or lifting tool directly, without using separate lift buttons.
The solution reduces physical strain, speeds up work stages and helps prevent handling errors.
Who is Gravity Ant for?
Gravity Ant is a good solution when:
- many lifts are made during a shift
- the load is too heavy or awkward to lift by hand
- the load must be positioned precisely
- a standard dual-speed hoist is too slow or imprecise
- you want to improve ergonomics
- the springiness of a pneumatic balancer interferes with the work
- you want to shorten production lead times.
Typical applications include machine shops, assembly lines, the automotive industry, warehouses, packing facilities, and machine and component manufacturing.
Key benefits of Gravity Ant
- Fast and precise load handling
- Stepless lifting speed control
- Float Mode balancing function
- Ergonomic one-hand control
- Suited to repetitive, fast-paced lifting
- No springiness or sway typical of pneumatic systems
- Runs on a standard single-phase 230 V supply
- Compact design and quick commissioning
- Several mounting and suspension options
- Grippers and lifting tools designed for the load
Float Mode – move the load by hand
Float Mode makes the load almost weightless from the operator’s point of view. Once activated, the operator can raise and lower the load simply by guiding it by hand.
The function is particularly suited to:
- precise positioning of components
- assembly of machines and equipment
- loading parts into machine tools
- handling boxes, sacks and packages
- repetitive production line lifts
- handling fragile products.
The load moves in a controlled way without the springiness typical of pneumatic balancers. This improves positioning accuracy and keeps operation stable even in fast, repetitive work.
Ergonomic IBOX control
Gravity Ant is operated with the ergonomic IBOX controller. With the sliding handle mechanism, the operator controls lifting direction and speed with a natural hand movement.
Controller features include:
- stepless lifting and lowering speed control
- real-time load display
- one-button Float Mode activation
- presence sensor that detects the operator’s hand
- adjustable interface for a hook or load-handling device.
Comprehensive safety features
Gravity Ant has monitoring functions to protect the load and the operator:
- STO safety function for fast stopping (Safe Torque Off [servomoottori])
- operator hand detection on the controller
- slack wire rope monitoring
- adjustable virtual lifting zones
- virtual slow-down zones
- automatic speed adjustment to the load
- Float Mode fall protection – stops the load if the operator stumbles or falls against it.
- automatic wire rope service life monitoring
- load cell calibration self-check
- mechanical holding of the load during power failure and overload.
The settings can be adapted to the application, the load and the working area.
Mounting options
Gravity Ant can be configured in several ways depending on the workstation and the required range of movement.
Articulated arm model
The articulated arm allows the load to be moved flexibly over a wide working area. Suited to individual assembly and production stations.
Linear jib model
Combined with a profile jib, this model suits work where the load is moved in a controlled way within a defined area.
Linear rail model
Combined with a light crane system, Gravity Ant serves several workstations or a larger rectangular working area.

| 100 kg | 60 m/min | 50 m/min | 45 m/min |
| 200 kg | 35 m/min | 25 m/min | 24 m/min |
| 300 kg | 26 m/min | 17 m/min | 16 m/min |
Load-specific grippers
The full benefit of a lifting manipulator is achieved with a gripper designed for the product being handled. Gravity Ant can be fitted with, for example:
- a mechanical gripper
- a vacuum gripper
- a magnetic gripper
- a hook or lifting eye
- a gripper for sheets and boxes
- a reel and shaft gripper
- a tilting or rotating lifting tool.
Tuotetekno designs and supplies the complete package according to the workstation, the load and the customer’s production process.
Accessories
Several accessories supporting operation and maintenance are available for Gravity Ant:
- separate operation and service display
- movable base plate
- IoT monitoring for usage and operating hours data
- remote status monitoring
- external arm brake
- external remote control.
With the movable base plate, in some applications the system can be installed without permanent floor fixing and later moved to another workstation.
