Safe and Efficient Wheel Handling up to 750 kg with Double-Rope and Rigid-Arm PM Manipulator Models
A New Era in Wheel Handling: Pneumatic Power, Maximum Efficiency
In the automotive, white goods, and metal processing industries, wheel handling and disk positioning operations are critical processes that must be carried out quickly and without damaging delicate surfaces.
Manual handling methods pose ergonomic and safety risks for operators while also slowing down production.
PM Industrial Manipulators make the loading, unloading, positioning, and assembly of wheels and metal components fast, safe, and ergonomic through a fully pneumatic balancing system.
Precise Handling with Pneumatic Manipulator Technology
PM Manipulators operate with a 100% pneumatic system, offering high energy efficiency without any electrical connection.
Using the ergonomic control arm, the operator can securely grip the wheel, change its orientation, and place it at the assembly point with the correct angle.
This system ensures maximum control during the handling of circular metal parts, wheel bodies, and steel discs.

Suitable PM Models
To improve Google search optimization (CTR), product groups are listed as separate subheadings for better visibility:
Double-Rope Models (Light & Medium Duty)
Double-rope manipulators are ideal for wheel handling lines requiring precision and balance.
The load is pneumatically balanced across two ropes, allowing the operator to maneuver it effortlessly with one hand.
PM Supporter – up to 60 kg
Compact structure and wide working radius; ideal for aluminum wheel handling.
PM Transporter – up to 120 kg
Enables fast transfer of medium-weight wheels and discs between production lines.
PM Gentle / Helpful – up to 180 kg
Smooth lifting motion and balance control make it perfect for assembly lines.
Rigid-Arm Models (Heavy Duty)
Rigid-arm manipulators provide high stability when handling heavy or unbalanced wheels and mold parts.
Their fixed-arm structure absorbs load torque directly, ensuring vibration-free operation.
PM Forceful – up to 450 kg
Ideal for handling steel wheels with a 90° rotation feature.
PM Powerful – up to 750 kg
Ensures maximum safety for large-diameter wheels and casting molds.
