500-3500kg 1-100m Truss Robot Linear Track 0.02mm Repeatability for Machine Tending

Truss Robot Linear Track for Machine Tending and Long-Stroke Handling

A truss style 500-3500kg truss robot track puts the robot above the work area instead of beside it. The gantry carries one to three robots on a rigid beam that travels over machine tools, pallet positions or welding fixtures, freeing floor space and giving a 1-100m stroke linear rail in 1000mm increments. The structure is built from welded steel sections machined after stress relief, driven by AC servo motors on hardened racks, and holds 0.02mm repeatability even at travel speeds of 1-2m/s. Robots can be side mounted, inverted or mounted for downward reach, which makes the same platform suitable for machine tending, long-run palletizing and welding of large fabrications. Because the beam is above the process, chips, coolant and weld spatter stay away from the rail, an important point in machine tending gantry duty where reliability matters more than peak speed.

Technical Specifications

Design Advantages

• Floor space recovered: the beam sits above the machines, so aisles and operator zones stay clear.
• Multi-robot economy: one gantry can carry two or three robots, sharing the structure and the safety envelope.
• High stiffness: stress-relieved welded sections and machined mounting faces keep deflection low at full extension.
• 0.02mm repeatability: absolute servo feedback with rack compensation holds position at every metre of the run.
• Serviceable: walkable maintenance platforms, accessible drive groups and modular joints simplify on-site work.

Typical Applications

• Machine tending across rows of CNC lathes and machining centres
• Palletizing and depalletizing in high-throughput warehouses
• Welding of long beams and frames where the robot travels over the fixture
• Loading and unloading of press lines and heat treatment racks
• Castings handling and deburring cells with heavy workpieces

Frequently Asked Questions

Q: When should I choose a truss robot track instead of a floor rail?
Choose the truss when floor space is tight, when several machines sit in a row, or when the robot must reach down into machines. A 500-3500kg truss robot track keeps the drive above the process, whereas a floor rail is simpler when the robot works at floor level.

Q: Can the 1-100m stroke include curves or branches?
The standard product is straight line. Curved and branched layouts are engineered case by case; send a plant layout and we will confirm whether a transfer or turntable is needed.

Q: How many robots can one gantry carry?
One to three as standard, more with a heavier beam design. Each robot is normally an independent external axis group, so programs stay separate.

Q: What is required on site before installation?
A level floor with anchor capacity verified by the customer, 0-45°C, humidity below 75% RH without condensation, vibration under 0.5G, and three-phase power sized to the drive group.

Engineering and Delivery

Gongboshi Robot Technology designs and builds gantry and truss handling systems in Shanghai, with a team of more than 100 engineers covering mechanical design, robot programming and commissioning. Structural parts are checked dimensionally after welding, drive groups are run in before dispatch, and each project includes a factory acceptance report, foundation drawings and remote support during installation. Standard spans ship in 30-50 working days, and the 12-month warranty covers the structure, drive and control package. Send your machine layout and workpiece data for a machine tending gantry proposal.
