Yale CTP Integral Trolley Clamp

Model CTP | Capacity 1,000 – 3,000 kg | Central Threaded Spindle | Zinc-Plated | Size A & B Beam Variants | German Engineered

The Yale CTP is an integral trolley clamp that converts any suitable overhead I-beam into a temporary attachment and load-transport point — no permanent installation required. Hung directly onto the lower flange and secured by a central threaded spindle, the CTP gives a quick rigging point that can be repositioned by loosening the spindle, sliding to the new location, and re-tightening. The spindle and clevis are zinc-plated for corrosion protection. Two size variants (A narrow flanges, B wide flanges) cover the standard beam profile range. Particularly useful for maintenance and one-off lifts where a permanent runway track isn't justified.

Technical Specifications

Maximum beam flange thickness 15 mm (CTP 1-A) or 25 mm (CTP 2/3 all variants).

Key Features

• Central threaded spindle: Quick adjustment to required beam flange width — no extra tools.
• Zinc-plated spindle and clevis: Corrosion protection for outdoor and humid industrial environments.
• Easy fitting: Slide onto flange, set spindle, tighten — quick install without dismantling structure.
• Three capacity tiers: 1,000 / 2,000 / 3,000 kg.
• Two size variants on 2 t/3 t models: A-size 75-200 mm; B-size 200-320 mm. 1 t is A-size only.
• Compact headroom: From 82 mm (CTP 1-A) — much more compact than permanent trolleys.
• Low minimum curve radius: Down to 0.6 m for CTP 1-A — suitable for tight monorail layouts.

Suitable Applications

For temporary monorail attachment, plant and equipment installation lifts, maintenance and repair lifts where a permanent runway track doesn't exist, structural steel hangs, and any application where a small chain hoist needs to be attached to an overhead beam for a defined task. Moved as needed, stored when not in use, clamps to virtually any suitable I-beam.

How to Use the Yale CTP

1. Confirm beam compatibility: Flange width within range; thickness max 15 mm (CTP 1-A) or 25 mm (others).
2. Slide onto flange: Open spindle far enough to slide clamp onto the flange (from beam end or break).
3. Position at working location.
4. Tighten the spindle: Turn threaded spindle until the clamp grips the flange firmly with no movement.
5. Attach hoist: Hook suspension to CTP clevis. Engage safety latch.
6. Inspect after first load: Confirm spindle remains tight.

Warning: Confirm the supporting structure can take the load before applying the hoist. Yale hoists and trolleys are not designed for passenger elevation.

Safety Information

• Confirm the beam structure is rated for the load before attaching the CTP.
• Verify beam flange width and thickness within rated range.
• Never exceed the Working Load Limit.
• Check spindle tightness before each lift.
• Never use to lift, lower or transport persons.
• Do not use as a horizontal pulling anchor — designed for vertical suspension only.
• LOLER 1998 thorough examination every 12 months.

Inspection and Maintenance

Requires inspection of spindle threads, clevis, clamp body and zinc plating. Spindle thread wear, deformation of clamp jaws, or loss of zinc plating on critical surfaces requires withdrawal from service. WOLFF Onsite provides LOLER inspection and overhaul services.

Optional Accessories

• Yale YC beam clamp alternative: For higher capacities (up to 10,000 kg) and screw-jaw design.
• Yale HTP push trolley: If you need to move the load along the beam after suspension.
