Overview
The 30T Heavy-Duty is the 30 tonne model in the heavy-duty line of Siasun's customised mobile robot portfolio. In automotive press shops it takes mid-size dies and sheet packs from store to press with a piggyback or chain conveyor superstructure and transfers the die onto the press bed; shipyard steel blocks and metallurgical slabs are in the same class. Lifting height is 80-100 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 30T Heavy-Duty to heavy industry and logistics projects in Turkey with enterprise supply, commissioning and engineering support.
30 tonnes, 80-100 mm
It drives under a thirty-tonne die or steel block, lifts it 80 to 100 mm and approaches the press or station from any direction; a chain conveyor transfers the die onto the bed.

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.

80-100 mm lift, ISO 3691-4
The lifting mechanism raises the load by 80-100 mm; emergency stop, audible and visual alarm, non-contact anti-collision. Heavy-duty designs follow ISO 3691-4 at PL d and e.
30T Heavy-Duty: Technical Analysis
Die change in the press shop
As automotive design cycles shorten, press shops change dies more often; every change moves a die of tens of tonnes from store to press and back, and waiting for the crane idles the line. Siasun heavy-duty robots carry dies and sheets between stations and presses with piggyback and chain conveyor mechanisms; robots in this application carry dies of up to 60 tonnes. The 30T Heavy-Duty is the edition scaled for mid-size dies and sheet packs: it drives under the die, lifts it 80 to 100 mm, approaches the press from any direction and transfers the die onto the press bed with a chain conveyor. Crane waiting disappears and die change becomes part of the robot route.
Its place in the heavy-duty line
The 30T Heavy-Duty sits above the line's 20T model and below the 60T; the series starts at the 3T, 5T and 10T and scales to 120 tonnes through the 80T. All models share the same navigation options, ±10 mm positioning, omnidirectional motion and safety hardware; the distinction is payload, lifting height (80-100 mm on the 30T) and the superstructure designed to the workpiece. Thirty tonnes is also the class of shipyard steel blocks and metallurgical slabs; Zoomlion Heavy Industry and the Wuhan locomotive maintenance base are among the sites where Siasun heavy-duty robots work.
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 30 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).
