SIASUN Dual-Lift Automotive Assembly Mobile Robot (Dual-Lift Automotive Assembly Mobile Robot)

A chassis frame is long, heavy and awkward in exactly the way that punishes a single point of support. Its mass sits towards the ends, and a small tilt at one end becomes a real misalignment at the other. Holding it on two fixed points restores the balance but ties the factory to one geometry. The SIASUN Dual-Lift Automotive Assembly Mobile Robot addresses both problems together. It carries the load on a pair of scissor lifts whose spacing can be varied, so that chassis and front and rear axles arrive at the marriage point level, supported where they need to be and ready to dock.

Robots Middle East sells and supplies the SIASUN Dual-Lift Automotive Assembly Mobile Robot to vehicle manufacturers, component makers and system integrators across the Middle East. Each quotation is prepared against the customer's own process. Robots Middle East coordinates delivery to site and remains the point of contact for support once the robot is working on the line.

Background

SIASUN and its robotics heritage

SIASUN is a Chinese robotics and automation company with roots in the research tradition of the Shenyang Institute of Automation of the Chinese Academy of Sciences. Its portfolio covers industrial robots, mobile robots and complete automation systems, and mobile robots for factory logistics are one of its established lines. The automotive assembly series sits within that family, alongside heavy-duty carriers for bulk loads. Both follow the same principle: an autonomous platform designed around a specific handling task, rather than a general-purpose cart with a fixture added afterwards.

A carrier designed around its lift

The defining feature of this robot is its dual-lift scissor structure. Two scissor lifts work together to raise the load, giving synchronised multi-point lifting rather than a single central jack. The spacing between the lift points is variable, so the same robot can provide support at different positions according to the assembly it carries. The lift platform can also float in X, Y and angle. As a result, the robot can dock precisely with the tooling at the station, rather than depending on the body or fixture being exactly where the drawing places it. SIASUN names single-lift, dual-lift, triple-lift and four-lift versions in the series. This page covers the dual-lift version only, and every figure below belongs to it.

Technical Specifications

Specifications are as published by the manufacturer and are confirmed against the datasheet at quotation.

The manufacturer has not published the dimensions, vehicle weight, battery type and capacity, operating time, travel speed, safety sensors, navigation method, charging time, scope of delivery or IP rating; Robots Middle East confirms these at quotation.

How does the Dual-Lift robot cope with a mixed-model assembly line?

A line that builds several models in sequence presents a difficulty that fixed handling equipment struggles with. Wheelbases, axle positions and support points change from one vehicle to the next, yet the station tooling expects every assembly to arrive in a predictable way. SIASUN designed this robot to support mixed-model assembly lines, and the variable lift spacing of 2450–3100 mm is the mechanical basis for that. Instead of one fixture per model, the distance between the two lift points can be matched to the assembly being carried.

SIASUN also describes the robot as customisable for multi-model process requirements. This matters because no two plants sequence their models in the same way, and the handling interface is usually where the differences appear. In practice, the integration discussion focuses on which models share the line, where each needs support and how the carrier should present the load at each station.

The robot is compatible with multiple charging methods, and its charging and transfer options are configurable to allow for scalability. For a plant planning to add models or stations over time, this means the energy and transfer concept can be adapted to the site rather than the site being rebuilt around the robot. As new variants arrive, the robots can be reassigned and reconfigured instead of replacing a fixed conveyor section.

Why does lift platform float matter at the docking point?

Reaching the station is only half of the task. The robot navigates to ±10 mm / ±1°, which places the load close to its target. The last few millimetres of alignment between an axle and its mounting points, however, are where assembly either flows or stops. The lift platform float of X ±125 mm, Y ±50 mm and ±2° in angle gives the platform room to settle into the tooling and the mating parts during docking, rather than forcing them together.

The lifting stroke of 1000 mm allows the robot to raise an assembly a long way from its travelling position to meet the body above. Because the two scissor lifts work in synchronisation, a long chassis or axle set rises evenly instead of rocking about a single point. Dual steering-wheel drive gives the robot the manoeuvrability it needs to approach a station on the correct line. Together, these features deal with the problem set out at the start: a heavy, elongated load presented level and in the right place, with enough compliance to complete the joint. SIASUN supports this with high-precision navigation and multi-layer safety protection for efficient, stable and safe assembly operations.

Who is the SIASUN Dual-Lift Automotive Assembly Mobile Robot for?

The clearest buyers are vehicle manufacturers running final assembly, where the marriage of chassis, front axle and rear axle to the body is a defined station that currently depends on fixed conveyors, lift tables or manual handling. The robot is designed for exactly that chassis and front and rear axle assembly, and its total load of up to 3000 kg places it at the heavy end of component delivery inside an assembly hall.

A second group is plants building several models on one line, or expecting to do so. For them, variable lift spacing and multi-model customisation are the main reasons to choose an autonomous carrier over a fixed installation. A third group is system integrators designing new or extended assembly lines in the region, who need a carrier that can be configured for charging, transfer and station layout as part of a wider project.

The series also includes single-lift, triple-lift and four-lift versions. The number of lift points suited to a particular process depends on the assembly and the station design. Robots Middle East is glad to compare the versions with you before a quotation is prepared, so that the specification matches your process rather than a catalogue entry. Buyers looking at the wider range can explore SIASUN Mobile Robots or our broader selection of Factory Robots.

What is the SIASUN Dual-Lift Automotive Assembly Mobile Robot used for?

1. Chassis marriage — delivering the chassis to the body on the line and raising it into position for joining.
2. Front axle assembly — carrying the front axle to its station and docking it precisely with the mounting points.
3. Rear axle assembly — presenting the rear axle level and aligned, supported at the spacing it requires.
4. Mixed-model line feeding — adjusting the lift spacing to suit successive models sharing the same assembly line.
5. Line reconfiguration — replacing fixed conveyor or lift sections with autonomous carriers that can be redeployed as the process changes.
6. Scalable assembly logistics — extending the fleet with configurable charging and transfer options as stations and volumes grow.

Pricing and Availability

Summary

A long, heavy assembly needs more than one point of support, and a modern line needs those points to move as its models change. The SIASUN Dual-Lift Automotive Assembly Mobile Robot combines both requirements. Its synchronised scissor lifts carry chassis and axles level, the variable spacing follows the model, and the floating platform completes the docking that navigation has brought within reach. Configurable charging and transfer options allow the solution to grow with the plant.
