Motor Block Inner Spade Handling
PM Manipulators: Safe and Precise Handling of Motor Core Blocks in Foundries and Casting Facilities
Challenges in Handling Motor Core Blocks
Motor block casting uses sand cores (“maçalar”), which are:
Manual handling risks product loss and production delays.
PM Industrial Manipulators address these challenges with pneumatic balancing systems, allowing safe and precise handling even for unevenly weighted cores.
Core Block Handling Technology
The pneumatic balance system neutralizes the core’s weight, letting the operator guide it effortlessly.
0°–90° rotation ensures cores can be positioned vertically or horizontally.
Specially designed grippers or vacuum tools protect fragile surfaces during transport.

Twin-Rope Models – For Light and Medium Cores
Designed for precise and balanced transport of medium-weight cores.
Pneumatic balance makes the load “weightless,” enabling single-operator safe handling.
-
PM Transporter – Up to 120 kg
Ideal for small motor cores and mold parts.
Advantage: Compact, fast loading, low energy consumption.
-
PM Helpful – Up to 180 kg
For medium cores; twin-rope design ensures balance even with uneven loads.
Advantage: 360° rotation, precise transport, silent operation.
-
PM Gentle – Up to 250 kg
Handles larger and heavier cores with high stability.
Advantage: Vibration-free movement, long-lasting mechanical structure.
Rigid-Arm Models – For Heavy and Large Cores
Rigid-arm models provide maximum safety for heavy and unbalanced cores.
The arm directly carries the load, ensuring vibration-free and controlled movement.
