Caldwell Wall Pick Lifting Clamp

Wall Pick Lifting Clamp — Safe, Efficient Prefab Wall Panel Lifting

The Model WP Wall Pick is a heavy-duty wall panel lifting clamp engineered for contractors handling prefabricated wall panels in housing and building construction. Rated at 1.25 tons, it is designed specifically to lift wall panels from a horizontal to a vertical position, making it a purpose-built tool for framing and panel-setting operations. The clamp's rugged construction and included 50-foot release rope streamline the pick-and-place process on the jobsite.

Unlike generic lifting clamps, the Model WP features a locking mechanism that prevents premature release while the load is still suspended — a critical safety advantage over non-locking alternatives. The included 50-foot release rope further differentiates this unit by eliminating the need for a second person to manually unhook the clamp at height, allowing the crane or equipment operator to release the clamp safely from the cab.

Key Features & Benefits

Load-Locking Safety Mechanism

The clamp locks automatically while loaded, preventing accidental or premature release during the lift. This reduces the risk of dropped loads and keeps the crew safer throughout the panel-setting operation.

50-Foot Release Rope Included

The included 50-foot release rope allows the equipment operator to release the clamp from the cab once the wall panel is set and secured — no additional person is required to climb or reach the top of the panel to unhook. This saves labor and eliminates exposure to work-at-height hazards.

Open Lower Lifting Plate

The lower lifting plate features an open design that clears nails or bolts protruding from the panel face. This allows the clamp to seat properly on real-world framing lumber without requiring panels to be cleared of fasteners before lifting.

Purpose-Built for Horizontal-to-Vertical Panel Lifts

The Model WP is specifically designed to upend wall panels from flat to standing — the exact operation required when setting prefab wall sections on a residential or commercial framing site. This focused design ensures the clamp performs reliably in its intended application.

ASME-Compliant Construction

The Model WP complies with ASME standards, providing contractors with confidence that the clamp meets recognized industry requirements for lifting equipment safety and performance.

Common Applications

Prefabricated Wall Panel Setting

Designed to pick and place prefabricated wall panels used in housing and building construction, making it the go-to clamp for framing crews working with shop-built or factory-built wall sections.

Horizontal-to-Vertical Panel Upending

Used to rotate wall panels from a flat, horizontal position to a vertical standing position — the critical transition step when erecting prefab walls with a crane or lifting equipment.

Single-Operator Panel Release

The 50-foot release rope enables the crane operator to release the clamp remotely from the cab after the panel is set, supporting single-operator workflows and reducing crew requirements for each lift cycle.

Compatible Materials

• Prefabricated wood-framed wall panels (housing and building construction)
• Wall panels with nails or bolts present on the lifting surface (cleared by open lower plate design)
• Wall panels with load widths between 4 in. and 6 in. (for WP-1.25-4/6 model)

Frequently Asked Questions

Q: Can the Model WP be used to lift panels from vertical to horizontal (downending)?
A: No. The Model WP is designed to lift panels from a horizontal to a vertical position only. It is not rated or intended for downending operations.

Q: Does the clamp require a second worker at height to release it after the panel is set?
A: No. The included 50-foot release rope allows the equipment operator to release the clamp from the safety of the cab once the panel is set and secured, eliminating the need for an additional person at height.

Q: Will the clamp accidentally release while the panel is suspended?
A: No. The locking mechanism prevents the clamp from releasing while it is loaded, providing an additional layer of safety during the lift.

Q: Can the clamp handle panels with nails or bolts on the surface?
A: Yes. The lower lifting plate has an open design specifically to clear nails or bolts, allowing it to seat properly on real-world framing panels without requiring fastener removal.
