3arm series support tools in a balanced state and allow spatial movement for assembly, fastening and machining.
Ergonomic arms and manipulators for safer work
3arm by Tecnospiro Machine Tool develops tool balancing arms and load manipulators. Hadi Technologies is a local contact in Israel for evaluating arm, interface and tool fit.

3arm is a Spanish brand from Tecnospiro Machine Tool, founded in 1987 with expertise in tapping arms and ergonomic motion solutions. Its arms help keep tools or fixtures balanced, reduce torque reaction and give operators better control through the work cycle.
The range includes tool holding series, arms with multiple interface heads, manipulators for lifting and placing parts, and SmartControl options for programmed positions and fastening sequences. The site cites tool loads up to 70 kg and manipulators up to 50 kg, while actual selection depends on model, interface and application.
3arm series support tools in a balanced state and allow spatial movement for assembly, fastening and machining.
Manipulators support picking, moving and placing parts between conveyors, stations and machines.
Compatible versions can define work positions and fastening sequences for a more repeatable process.
Load balancing can reduce repeated operator effort
Interface heads and supports build around the task
Choose a tool arm or part manipulator
3arm planning needs tool or part weight, reaction torque, reach, anchoring, cycle rate and gripping method. These inputs determine a tool arm or a manipulator.
The task can then be reviewed for column, rail or mobile support, interface head and SmartControl where repeated positions or fastening sequences are needed. Capacity and availability are model dependent.
Ergonomic arms balance tools or devices, with suitable models listed by the manufacturer up to 70 kg. A manipulator is intended to pick and place parts, and the site lists capacities up to 50 kg. These are different ratings, so model, interface head, reach and load movement must be checked rather than comparing numbers alone.
Define tool torque, reaction direction, mounting point, tool weight and centre of gravity. The arm assists with balance and reaction management, but model and adapter must suit the load and geometry throughout the travel. Review a station drawing and tool data before specifying the arm.
SmartControl is useful when a repeated sequence of positions or tightening steps should be guided for the operator. Position programming does not by itself prove correct torque, so it should be combined with a suitable fastening tool and process control. Define positions, tolerance and the response to an out of sequence or out of tolerance condition.
Provide tool or part weight, dimensions, centre of gravity, grip points, required travel and mounting environment. 3arm lists different interface heads, and the connection affects balance, access and safety. Without these inputs it is not possible to confirm whether a standard adapter is sufficient.
