Caldwell Model 90 Standard Fixed-Forks Pallet Lifter — Converts Overhead Cranes to Lift Trucks

The Caldwell Model 90 Standard Fixed-Forks Pallet Lifter (Item No. 35-0133) is a below-the-hook lifting device engineered to convert an overhead crane into a fully functional lift truck. Designed for industrial and construction environments where pallet loads must be moved in areas that are difficult for conventional forklifts to access, the Model 90 attaches to an existing crane system and provides reliable, controlled pallet handling. With 16 standard configurations spanning capacities from 1 ton up to 10 tons and fork lengths from 36 to 60 inches, this lifter is built to handle a broad range of material handling requirements.

Unlike standard forklift attachments or improvised rigging solutions, the Model 90 is counterbalanced to hang level when empty, eliminating the operational hazard of a tipping or unbalanced lifter between picks. It requires zero maintenance and complies fully with ASME below-the-hook lifting device standards, making it a code-compliant, set-and-forget addition to any overhead crane system. When standard configurations do not meet your needs, Caldwell offers custom designs and additional Lightweight and Heavy-Duty model variants.

Key Features & Benefits

Overhead Crane Conversion

The Model 90 allows any overhead crane to perform the work of a lift truck without the capital cost of additional powered equipment. This is critical in facilities where crane infrastructure already exists but floor space or aisle width prevents forklift access to load or unload palletized materials.

Counterbalanced Empty Hang

The lifter is engineered to hang level when forks are unloaded, preventing the dangerous forward tilt common in non-counterbalanced below-the-hook devices. This improves operator safety and allows for easier fork insertion into pallet entries, reducing cycle time on repetitive lifts.

Maintenance-Free Construction

No grease fittings, no hydraulic components, no wear-prone actuators — the Model 90 is a fully passive mechanical device that requires no scheduled maintenance. For high-throughput operations, this eliminates downtime and reduces total cost of ownership over the product's service life.

16 Standard Configurations

With fork lengths of 36, 42, 48, 54, and 60 inches and capacities from 1 to 5 tons in a single standard lineup, contractors and facility managers can specify the exact configuration that matches their load geometry and crane capacity. Bail opening height on item 35-0133 is 5 inches.

Ease of Access in Restricted Areas

The suspended design allows operators to move palletized loads into areas where floor-mounted lift equipment cannot reach — including mezzanine edges, confined bays, and elevated platforms. This significantly expands the utility of existing crane infrastructure.

ASME Standards Compliance

Full compliance with ASME below-the-hook lifting device standards ensures the Model 90 meets third-party safety and load rating requirements. This is essential for facilities subject to OSHA inspections, insurance audits, or contractual safety compliance requirements.

Common Applications

Manufacturing Facility Material Handling

Move palletized raw materials or finished goods in production environments where forklift clearance is limited or crane infrastructure is already in place.

Loading Dock and Staging Operations

Position pallets precisely at dock edges or elevated staging areas where a conventional forklift cannot maneuver safely or efficiently.

Crane Bay Transfers

Shift palletized components between workstations within the same crane bay, reducing the need for secondary handling equipment and lowering labor costs.

Elevated Platform and Mezzanine Loading

Lift pallets to or from mezzanine levels, racking systems, or elevated work platforms where powered lift trucks cannot operate.

Tight-Aisle Warehouse Operations

Deploy in narrow-aisle or congested storage environments where overhead crane coverage exists but floor equipment access is obstructed.

Custom or Specialty Load Handling

When standard pallet jack or forklift handling is not appropriate for fragile, oversized, or high-value loads, the Model 90 provides a controlled, crane-guided alternative.

Compatible Materials

Standard wooden pallets
Plastic pallets
Steel skids and metal pallets
Palletized construction materials (block, brick, bagged goods)
Palletized industrial components and machinery parts
Boxed or crated loads on pallet bases
Drums and containers on pallet bases

Frequently Asked Questions

Q: What overhead crane capacity do I need to use the Model 90?
A: Your overhead crane must be rated at or above the capacity of the Model 90 configuration you select, plus the weight of the lifter itself. Refer to the specification table for individual model weights, which range from approximately 245 lbs. to over 1,400 lbs. depending on configuration.

Q: Does the Model 90 require any modifications to my existing crane?
A: No modifications are required. The Model 90 connects to your crane hook via the bail. Confirm your crane hook dimensions are compatible with the bail opening on your selected configuration (5 in. for item 35-0133).

Q: How much headroom is required above the load for safe operation?
A: Caldwell recommends an additional 3 to 4 inches of clearance above the load to allow for ease of loading and unloading the lifter onto and off of the pallet.

Q: Can the Model 90 be customized for non-standard pallet sizes or higher capacities?
A: Yes. Caldwell offers custom design services for applications that fall outside the 16 standard configurations. Contact Caldwell at 800.628.4263 to discuss custom fork lengths, capacities, or bail placements. Lightweight and Heavy-Duty model variants are also available.

Q: Is the Model 90 compliant with safety regulations?
A: Yes. The Model 90 complies with ASME standards for below-the-hook lifting devices, which are the applicable industry standards for this equipment type in the United States.

Q: What is the difference between the Model 90 and the Model 93W?
A: The Model 93W Wheeled Pallet Lifter includes wheels that allow the unit to be tilted and rolled from crane bay to crane bay without using the crane, features dual lift points that eliminate the need for a counterweight, and is designed to be lighter for easier manual handling. The Model 90 is a fixed, counterbalanced unit suited for stationary crane bay use.
