Precast Concrete Forged Steel Lifting Ring Clutch

Product Description

Ring Clutch Introduction

GME Ring Clutch consists of a clutch body, a curved bolt, and a high strength bail. the curved bolt is free to move in any direction. The clutch in each load group matches the shape of the recess former and incorporates a locking bolt which engages in the head of the cast-in anchor.

Material and safety of ring Clutch

GME CE certificated lifting clutch (ring clutch) with high-grade 35CrMoV special casting head clutch and forged bolt. The forged bolt needs the same materials as the head. The lifting clutch hook was made with enough thickness and high strength steel. The lifting clutch hook welded needs high quality and deeply to approval with X-ray machinery. The bail is made from robust, hardened, and tempered cast steel. The GME Ring Clutch meets the requirements of the "Safety regulations for lifting precast concrete units".

 

Ring Clutch Features

Installation and release are safe and simple.

After the clutch is inserted over the anchor head and into the recess, the curved bolt is rotated into the closed position. The rotation of the standard bail is a full 360°.

Once engaged and supporting 400 lbs of load, the ring clutch cannot be released.

Made with an electro-galvanized finish

Ring Clutch Application and Installation

Ring Clutch is used with Fleet Lift Anchor for lifting and handling of precast concrete panels. The Ring clutches are clearly matched to the anchors by compatible design as well as by marking the anchor types and load groups. Only matching components will fit together.

When the head of the lifting clutch inserted into the recess and anchor head, the bolt will lock down the anchor from the head of the lifting clutch. The lifting clutch casting head needs special head treatment to improve mechanical performance. 

1. The Ring Clutch is located directly over the head of a Fleet-Lift Anchor.

2. The ring clutch is pushed down onto the anchor head and the curved bolt is rotated through the engagement hole of the anchor and locked into position. The process of engaging the anchor and ring clutch is completed in seconds.

3. To disengage the anchor and ring clutch, simply pull the curved bolt free of the anchor. This allows the ring clutch to be easily removed from the head of the anchor.

4. Recommends a minimum ¾" cover between the bottom of an anchor and the concrete surface. This minimum recommended concrete cover is to prevent anchor corrosion.

5. Load line should be in line with the center of the bail, lifting from the top of the bail only. Bail should never contact the edge of concrete to avoid bending the bail.

Warning

GME Ring Clutches may become worn after extended use or maybe damaged through misuse, overloading, or a number of other factors, any one of which may affect the Safe Working Load of the Ring Clutch. Users must establish a system of periodic inspections which should include the following:

1. Inspect for general condition and wear.

2. Assure that the bail is free to rotate in all directions.

3. If the bail is bent or twisted, the ring clutch must be destroyed.

4. Check the curved bolt for wear, cracking, or bending.

5. Check the clutch body for wear, cracking, or deformation.

6. If it appears that the Ring Clutch has been heated in any way, the clutch must be destroyed.

7. Check the engagement slot, if the gap is larger than dimension H, the clutch must be destroyed. Destroy any unit that is worn, damaged, bent, or twisted by cutting off the bail.

8. No repair or welding is permitted.

 

Wire Rope Ring Clutch / Cable Ring Clutch

Wire Rope Ring Clutch consists of a cable, swage, clutch body, and curved bolt handle. Used with Fleet Lift Anchor System. Designed to be used specifically for flat steel lifting. Cable Ring Clutch is the same in function as the standard style ring clutch, for the exception of offering more flexibility. And it is fabricated with a wire cable bail for more versatility. It is often an effective solution for difficult lifting and rotation challenges.

Compared with the standard ring clutch, Cable is more flexible than bail allowing some latitude in the direction of the lift. Handle allows for more safe locking of clutch into lifting position

1 Available on special order or limited quantity on hand. Special orders take 4 to 5 weeks.

2 Not to be used with High Capacity System Anchors.

3 Clutch capacities are rated at a 5:1 safety factor.

 How to inspect & maintain the ring clutch and wire rope ring clutch?

1.Prior to an inspection, the Ring Clutch should be cleaned to ensure any cracks or damage can be seen by the inspector

2.Visually inspect the cable for any kinks and buckling. Inspect for broken cable/wire/strand braid, cable compression deformation, cable corrosion scarring, and an excessive number of damaged or frayed wires. If the Ring Clutch fails any of these criteria it must be removed from service.

3.Inspect cable coupling for damage or severe wear. Check for signs of cable slippage in cable coupling. If an indication of applied heat is present, the unit must be removed from service

4.Visually inspect the clutch body for any splitting, cracking, deformation, applied heat, or damage. If the clutch body fails any of these criteria it must be removed from service.
