Cat® Spring-Actuated Pallet Carousel Features
Engineered to eliminate bending, reaching, and stretching during pallet build and breakdown operations, the Cat® pallet carousel skid positioner (WB641680) combines a self-leveling spring mechanism with a 360° low-friction turntable on a 43-5/8-inch platform rated for 4,500 pounds. As layers of product are added or removed, heavy-duty springs and a shock-absorbing dampener automatically raise and lower the Cat® carousel platform to maintain a consistent, ergonomic working height — without any external power source, electrical connection, or compressed air supply. Full 360° rotation lets operators load and unload from the nearest point rather than walking around the pallet.
For facilities prioritizing ergonomic compliance and low operating cost, the WB641680 is the zero-utility-cost model in Cat®'s pallet carousel line. Tubular steel construction with a powder-coat finish handles continuous warehouse and manufacturing use, and fork pockets (36-5/8"L × 6"W × 2"H) on the base frame allow forklift relocation across the facility. For workstations needing frequent repositioning without a forklift, the Cat® Portability Package WB641681 — sold separately — adds a handle and wheel kit for one-operator mobility.

Ergonomic and Safety Applications
To reduce the lifting, bending, and reaching that account for the majority of warehouse musculoskeletal injury claims, the Cat® WB641680 is deployed at pallet build stations in distribution centers, production line pack-out stations in manufacturing, receiving and shipping dock areas where pallets are loaded throughout the shift, and any workstation where workers spend extended time adding or removing product from palletized loads. Safety managers deploy it as a primary ergonomic intervention to meet OSHA general duty clause requirements for hazardous manual lifting.

Frequently Asked Questions
How does the Cat® spring-actuated pallet carousel maintain a constant working height?
A combination of heavy-duty springs and a shock-absorbing dampener inside the Cat® WB641680 automatically raises and lowers the platform as layers of product are added or removed from the pallet. When a layer is placed on the platform, the springs compress and the platform drops slightly to maintain the top of the load at a consistent, ergonomic working height. When a layer is removed, the springs extend and raise the platform. This self-leveling action eliminates operator bending and reaching throughout the build or breakdown of a full pallet load.
What is the load capacity range of the Cat® WB641680 pallet carousel?
The Cat® WB641680 operates across a capacity range of 400 to 4,500 pounds. Below 400 pounds, the springs maintain the platform at raised height without load. Above 4,500 pounds, the springs are fully compressed and the unit rests at its lowered height of 9-1/2 inches. For applications consistently near either end of the range, Cat® recommends verifying the spring configuration matches the expected load profile.
Does the Cat® spring-actuated carousel require power or a compressed air supply?
No. Fully mechanical by design, the Cat® WB641680 uses heavy-duty springs to provide all leveling force without any external power source, electrical connection, or compressed air supply. Virtually maintenance-free operation and no utility dependency at the workstation make it the lower-cost option within the Cat® carousel line compared to the airbag-operated WB641679, which requires an initial 60 PSI air charge. Any facility without dedicated air lines can run the WB641680 without modification.
Can the Cat® WB641680 pallet carousel be made mobile?
Yes. The Cat® Portability Package (Cat® Portability Package (WB641681)) is the factory-designed accessory for converting stationary Cat® pallet carousels into one-operator mobile units. The fork pockets on the WB641680 base frame also allow relocation by forklift across the facility floor. For frequent repositioning between workstations without a forklift, the Cat® Portability Package adds a long handle and wheel kit that one operator uses to tilt and roll the carousel to its new position.
Cat® Pallet Carousel Accessories
For workstations requiring repositioning without a forklift, the Cat® Portability Package (WB641681) converts the Cat® WB641680 into a one-operator mobile unit — available now at LabSupplies.com. For higher raised-height requirements or highly variable load weights, the Cat® Airbag-Operated Carousel (WB641679) uses a Firestone captive airbag and reaches 29-13/16 inches. Both Cat® carousel models are compatible with the WB641681 Portability Package.
