Pallet Inverters, Upenders and Pallet Rotators
Pallet inverters, rotators, and upenders are industrial load-turning machines used to reorient palletized loads, replace damaged pallets, transfer product to slip sheets, or reposition heavy materials for processing. Ergonomic Partners offers three categories of load-turning equipment: pallet inverters and rotators for 180-degree full inversion, mechanical upenders for 90-degree rotation of coils, dies, and cubic loads, and hydraulic barrel-style inverters for high-volume production line operations. All units are available in a wide range of capacities and can be custom engineered for your specific application.
Pallet Inverters and Rotators
Our standard pallet inverter handles loads up to 4,400 pounds and pallets up to 48" x 48" x 60" high. The robust steel unit comes with a handheld pendant station and inverts an entire pallet load 180 degrees. An anti-friction turret bearing with adjustable pressure control reduces the risk of product damage during rotation. Forklift pockets in the base allow quick relocation as needed.
The dual-clamp design moves both clamp plates equally toward center, keeping the load centered near the axis of rotation. This reduces stress on the rotating mechanism compared to single-clamp designs, and the use of cylinders and chains equalizes both movement and clamp force for consistent, controlled inversion.
Common applications include replacing broken or damaged pallets, transferring loads to slip sheets, recovering damaged product from the bottom of a load, and switching from shipping pallets to company-owned pallets. Contact us at (314) 884-8884 or request a quote for pricing and availability.

Upenders and Load Turners
Mechanical upenders rotate steel coils, dies, and other cubic loads 90 degrees for processing, storage, or transport. Each unit is custom engineered for your specific application and load profile. The cylindrical cradle sits on four machined rollers and is driven by a gear motor, with two square platforms of equal size on either side of the machine providing a stable, balanced rotation point.
Common applications include up-ending or down-ending coils and dies, repositioning heavy fabricated parts, and orienting loads for downstream processing or conveyor transfer. Available design features include:
- Capacities from 1,000 to 100,000 pounds.
- Custom platform sizes to match your load footprint.
- Flat platforms or V-saddles for round or irregular loads.
- 180-degree base rotation.
- Pallet centering.
- Gravity or powered conveyor integration.
- Tilt or shift platforms.
Hydraulic Barrel-Style Load Inverters
Barrel-style inverters are named for their circular frame design and are ideally suited for production line or high-volume operations. The circular configuration allows loading and unloading from the same point by either forklift or conveyor, minimizing floor space requirements and streamlining cycle times.
Barrel inverters are custom engineered to suit your application and can be configured with a wide range of options including:
- Long-reach hydraulic scissors clamping.
- Multi-direction clamping.
- Programmable logic controllers for automatic load and unload sequencing.
- Selectable pressure settings.
- Gravity or powered conveyor platforms.
Custom features are available to increase the efficiency and productivity of your specific process. Contact our team to discuss your application.
