Yale YC Beam Clamp

Model YC | Capacity 1,000 – 10,000 kg | Central Threaded Spindle | Securable Against Loosening | Horizontal Anchor or Lifting Clamp

The Yale YC is a versatile beam clamp providing a quick rigging point for hoisting equipment, pulley blocks, or loads themselves. The wide adjustment range covers I-beam flange widths from 75 mm to 320 mm depending on capacity, and the central threaded spindle gives easy attachment with a safe and secure grip. The spindle can be secured against loosening for extended-period applications. The YC also doubles as a horizontal rigging anchor or as a lifting clamp — broader functionality than dedicated trolley clamps. Five capacities cover the full load range from 1,000 to 10,000 kg in a single product family.

Technical Specifications

Key Features

• Wide flange adjustment range: One YC body covers a wide range — fewer SKUs across varied beam stock.
• Central threaded spindle: Easy attachment with a single tool. Spindle securable against loosening.
• Five capacities from 1 to 10 t: Covers full common range of rigging anchor and clamp applications.
• Multifunctional — suspension, horizontal anchor, or lifting clamp: Unlike dedicated trolley clamps.
• Black forged finish: Robust forged steel with industrial black coating for durability and visibility.
• Lightweight relative to capacity: YC 1 at 3.4 kg easy to carry, store and deploy.

Suitable Applications

Universal lifting and rigging beam clamp — temporary hoist suspension points, horizontal pulling anchors, lifting points for structural members, machine handling, mobile rigging operations. The dual function (suspension or anchor) makes the YC particularly useful in rigging and erection work where the role of the clamp may change during the job.

How to Use the Yale YC

1. Confirm beam compatibility: Flange width within YC's adjustment range.
2. Open the spindle: Back off central threaded spindle far enough to slide clamp onto flange.
3. Position at the working location.
4. Tighten the spindle firmly: Turn spindle until clamp grips flange securely.
5. Lock the spindle if required: For long-duration applications, secure against loosening.
6. Attach hoist or rigging: Connect suspension hook, shackle, or sling to the YC eye.
7. Test: Apply partial load and confirm clamp grip before full WLL.

Warning: Verify the supporting beam is rated for the load. Lifting clamp use requires the load in a stable geometry — refer to the Operating Manual.

Safety Information

• Confirm beam is rated for the load before attaching the clamp.
• Verify beam flange width within the YC's adjustment range.
• Never exceed the Working Load Limit.
• Tighten the spindle firmly and verify no movement before applying full load.
• Secure the spindle against loosening for extended applications.
• Never use to lift, lower or transport persons.
• When used as a lifting clamp, confirm load geometry suitable per Operating Manual.
• LOLER 1998 thorough examination every 12 months.

Inspection and Maintenance

Requires inspection of spindle threads, jaw faces, clamp body, lifting eye, and locking feature. Bent jaws, damaged threads, or loss of locking function requires withdrawal from service. WOLFF Onsite provides LOLER inspection and overhaul.

Optional Accessories

• Camlok SC92 alternative: For Screwlok design with integral shackle (capacities to 20,000 kg).
• Yale CTP integral trolley clamp: For chain hoist suspension on smaller beams.
