YASKAWA Electric Corporation has launched the MOTOMAN-GP215L, GP400L, and GP700 six-axis industrial robots, expanding its heavy-payload product range to address large-scale workpiece handling and bulk transport automation requirements.
Manufacturing Trends and Heavy Payload Requirements
In modern manufacturing facilities, individual workpieces and component sub-assemblies are becoming larger and heavier. Within the automotive industry, structural car body components, heavy die-cast metal parts, and modular battery cases are experiencing steady increases in physical dimensions and mass. Similarly, contemporary battery production processes require the bulk transport of multiple cells simultaneously to maintain throughput speeds.
Beyond automotive manufacturing, sectors such as construction machinery production, building materials processing, and industrial factory equipment fabrication face expanding demands to move large structural parts and massive processing jigs. To automate these tasks, manufacturing facilities require heavy-duty industrial robots engineered with an extended physical operating reach combined with a higher wrist load tolerance to stabilize bulk components.
Performance Specifications and System Lineup
The expanded product series introduces distinct mechanical advantages optimized across three specific models designed to streamline line architecture and maximize overall floor space utilization:
- MOTOMAN-GP215L: This model provides a maximum payload capacity of 215 kg paired with an extended maximum horizontal reach of 3114 mm. Its mechanical wrist load tolerance exhibits an upward improvement of up to 44% compared to conventional robot classes in its payload division.
- MOTOMAN-GP400L: Engineered for extended reaching requirements alongside high-load specifications, this unit delivers a payload capacity of 400 kg and a maximum horizontal reach of 3718 mm. The reach is 200 mm longer than previous model lines, while its wrist load tolerance is improved by up to 110% over traditional classes.
- MOTOMAN-GP700: Positioned as a high-load specification model for heavy material handling, this arm provides a payload capacity of 700 kg. It maintains a maximum horizontal reach of 2845 mm, matching the reach of previous generations while increasing the allowable mechanical wrist tolerance by up to 60%.
Structural Layout and Spatial Optimization
The mechanical layout of the series utilizes a compact structural footprint designed to reduce the active interference radius during rotational path movements. This compact geometry increases design flexibility when planning or modifying equipment layout configurations within standard factory footprints. By minimizing spatial interference contours, the robots support the efficient use of facility floor space, enabling factory designers to optimize production line layouts and shorten overall processing line lengths.
Factory Production Applications
The heavy-duty robot series is purposed for material handling and automation roles across several manufacturing sectors:

Factory Production Applications
The heavy-duty robot series is purposed for material handling and automation roles across several manufacturing sectors:
- Automotive Production: Interstage transport of structural car body components, high-mass die-cast parts, and integrated electric vehicle battery assemblies.
- Battery Manufacturing: Bulk transfer and palletization of raw battery cells during high-density pack assembly phases.
- Construction and Infrastructure: Rigging and transport of heavy industrial parts, large structural building elements, and high-mass fabrication components.
- Factory Tooling Logistics: Manipulation, positioning, and machine tending of large-scale mechanical workpieces and heavy processing jigs.
Additional Context
This section details technical specifications and competitive benchmarking not included in the original news release.
Heavy-payload industrial robots managing capacities between 200 kg and 700 kg are strictly evaluated by their static payload limits, maximum spatial reach, allowable wrist torque (moment), and wrist inertia. In high-inertia applications—such as moving offset automotive chassis panels or dense battery trays—the actual limit of an industrial robot is typically dictated by its dynamic wrist torque rather than its pure vertical lifting power.
Long-Reach Handling Metrics
Within the 400 kg payload classification, standard long-reach industrial robots, such as the M-900iB/400L or the KR 420 R3080, provide maximum horizontal reaches limited to roughly 3,000 mm to 3,100 mm. The MOTOMAN-GP400L extends this operational envelope by delivering a maximum reach of 3,718 mm while retaining its full 400 kg rating. This extended arm reach permits the extraction of large components from deep stamping presses or die-casting machines without requiring the installation of secondary, floor-mounted linear shuttle tracks, lowering total capital infrastructure complexity.
Wrist Load Tolerance and Dynamic Inertia
Traditional heavy-payload arms often suffer from restricted allowable moments of inertia when handling bulky, elongated objects that move the load center of gravity far away from the tool mounting flange. When comparable heavy robots encounter high-offset tooling, their velocity must be software-derated by up to 50% to prevent gear damage in the wrist axis.
The structural upgrades in the MOTOMAN-GP215L, GP400L, and GP700 series raise the wrist load thresholds by up to 44%, 110%, and 60% over conventional baselines. For example, when compared to standard 700 kg models like the MX700N—which features a reach of 2,540 mm—the MOTOMAN-GP700 provides an extended 2,845 mm reach while utilizing beefed-up wrist dual-bearing reducers. This architecture permits the manipulation of heavy processing jigs and offset loads at higher acceleration speeds without triggering servo-overload faults or structural resonance during emergency stops.
Enclosure Footprint and Interference Optimization
As factories transition to high-density manufacturing workcells, the base footprint and the rear clearance interference radius of large articulated arms affect layout efficiency. Conventional parallel-link or counterweighted heavy robots require large rear mechanical stabilization structures that sweep through a wide envelope, requiring expansive safety fencing.
The compact pivot design utilized in this expanded series limits the rear interference radius. This allows the base placement to sit in closer proximity to CNC machine beds, stamping fixtures, and peripheral safety barriers. By consolidating the primary link assembly, these arms permit a reduction in required floor allocation space per cell, helping shorten the spatial distance between sequential manufacturing stations along a unified production line.
