Overview
The 5T Heavy-Duty is the 5 tonne model in the heavy-duty line of Siasun's customised mobile robot portfolio. It is the first step of a series that starts at five tonnes and scales to 120; it drives under parts such as truck axles, large engine blocks, energy storage battery modules and welded steel panels, lifts them and carries them between stations at a steady speed. Lifting height is 100 mm, positioning accuracy ±10 mm and gradeability 3 percent. Navigation is chosen by site as SLAM, magnetic guidance or colour tape; in its heavy-duty robots Siasun uses natural contour, magnetic, inertial, laser, visual and base station navigation and combines several methods in complex environments. The wheel system balances load bearing with traction and protects the floor; the robot moves in every direction with no turning-radius constraint, carries without bumps under stable speed control and crosses obstacles. Safety hardware consists of an emergency stop, audible and visual alarms and non-contact anti-collision; heavy-duty designs follow ISO 3691-4 at PL d and e. In customised-product fashion, the body and auxiliary mechanisms are designed around the workpiece's centre of gravity, size limits, slope requirement and transfer method; piggyback, chain conveyor and turntable mechanisms are examples. Outdoor editions are protected against rain, snow and dust. The line scales from 3 to 120 tonnes and targets port and container logistics, new energy and energy storage, aerospace and shipbuilding, automotive and construction machinery manufacturing, and steel, metallurgy and heavy industry; references include high-speed train maintenance bases (2010-2015, more than 50 robots), press die transfer up to 60 t, heavy truck assembly since 2018 (10-20 t, dual-vehicle linkage), port container transfer since 2020 (65 t per robot) and energy storage editions in 2024. The robot switches seamlessly between multi-robot coordination and single-robot operation; the fleet layer is the IMRS 2.0 platform, whose TCS dispatch system connects to MES/ERP/WMS through VDA5050, OPC UA, Modbus and MQTT. Robotlar.org supplies the 5T Heavy-Duty to heavy industry and logistics projects in Turkey with enterprise supply, commissioning and engineering support.
5 tonnes, 100 mm
It drives under a five-tonne axle, engine block or battery module, lifts it 100 mm and carries it at a steady speed; the superstructure is designed to the part.
No turning radius
Omnidirectional motion: sideways, on the spot, diagonal. The wheel system spreads the load, keeps traction and protects the concrete.
Three navigation modes, ±10 mm
SLAM, magnetic guidance or colour tape; positioning ±10 mm in all three. Methods are combined on complex sites.
100 mm lift, ISO 3691-4
The lifting mechanism raises the load by 100 mm; emergency stop, audible and visual alarm, non-contact anti-collision. Heavy-duty designs follow ISO 3691-4 at PL d and e.
5T Heavy-Duty: Technical Analysis
The series' starting load
Siasun starts its heavy-duty robots at five tonnes and scales them to 120; the 5T Heavy-Duty is the first step of that scale. Five tonnes means a truck axle, a large engine block, an energy storage battery module or a welded steel panel in a shipyard; these are loads for which a fixed conveyor is expensive to build and a forklift risky to use. The robot drives under the load, lifts it 100 mm and carries it between stations at a steady speed. The wheel system spreads five tonnes on the floor while keeping traction; omnidirectional motion lets a die or an axle approach the machine sideways in narrow halls.
Its place in the heavy-duty line
The 5T Heavy-Duty sits one step above the line's 3T model and below the 10T; the series continues with the 20T, 30T, 60T and 80T. All models share the same navigation options, ±10 mm positioning, omnidirectional motion and safety hardware; the distinction is payload, lifting height (100 mm on the 5T) and the superstructure designed to the workpiece. Siasun is among the first Chinese manufacturers to enter heavy-duty mobile robots and runs this line in construction machinery, automotive and parts, metal processing, aircraft production, port logistics and energy storage.
Wheel system and omnidirectional motion
Tens of tonnes crack concrete unless they are spread; in heavy-duty robots the wheel layout therefore matters as much as capacity. The wheel system of the Siasun heavy-duty line balances load bearing with traction and protects the floor; the line scales from 3 to 120 tonnes. The robot moves in every direction with no turning-radius constraint: a 5 t load slides sideways in narrow assembly halls, turns on the spot and travels diagonally. Stable speed control delivers both throughput and bump-free transport; obstacle crossing and bump resistance bring adaptation to different process sites. The lifting mechanism drives under the load, raises it and sets it down at the station.
Navigation and safety
Navigation is chosen by site: SLAM laser mapping, magnetic guidance or colour tape; positioning accuracy is ±10 mm in all three. In its heavy-duty robots Siasun uses natural contour, magnetic, inertial, laser, visual and base station navigation and combines several methods in complex environments; most of the navigation sensors are its own developments. Safety hardware consists of an emergency stop, audible and visual alarms and non-contact anti-collision; heavy-duty designs follow ISO 3691-4 with safety levels engineered to PL d and e, and brakes, stall protection and actuator safeguards are added. Gradeability is 3 percent.
Customisation and outdoor use
The heavy-duty line is a customised product class: the body and auxiliary mechanisms are designed around the workpiece's centre of gravity, the robot's size limits, the slope requirement, the safety of oversized parts and the transfer and docking method; piggyback, chain conveyor and turntable mechanisms are examples. Outdoor editions are protected against rain, snow and dust, with safe outdoor navigation and charging part of the design; in 2024 waterproof, outdoor-capable, ultra-low-profile editions were developed for the energy storage sector. The robot switches seamlessly between multi-robot coordination and single-robot operation; the fleet layer is IMRS 2.0.
Applications
- Port and container logistics: container transfer at transhipment hubs (since 2020, 65 t class per robot).
- New energy and energy storage: moving containers and battery blocks in open yards.
- Aerospace and shipbuilding: large fuselage parts and structural steel.
- Automotive and construction machinery: press die transfer (up to 60 t), heavy truck chassis assembly (10-20 t, dual-vehicle linkage).
- Steel, metallurgy and heavy industry: coil, slab and heavy part handling.
- Rail maintenance: high-speed train frame maintenance bases (2010-2015, more than 50 robots).
