Coil Grabs

Bushman AvonTec manufactures a complete line of coil lifting equipment engineered to meet a variety of dimensional, capacity and special application needs. Quality-built throughout, these lifters will provide years of continuous, safe, efficient coil handling.

Bushman AvonTec manufactures coil grabs with heavy steel weldments to protect the integrity of the coil. They feature:

• Telescoping, motor-driven legs.
• Formed, curved saddles on the lifting surfaces.
• Limit switch in the lifting pad to prevent accidental opening under load.

 Optional features that enhance lifting efficiency and protect the integrity of the load include:

• Motorized rotation.
• Photo eyes to help in centering the coil.
• Limit switches at ends of leg travel.
• Full length pads on all coil contact surfaces.
• Rubber or steel toe rollers in the lifting pads.
• Built-in automatic weigh scales with on-board or remote display.

 Bushman AvonTec below-the-hook crane lifting attachments, including all coil grabs and coil lifters, are designed according to the latest revisions of ASME Specifications B30.20 and BTH-1, Design of Below-the-Hook Lifting Devices.

Motor Driven Coil Lifters, Model M5067

Combining operating efficiency, protection of the coil, and utilization of the overhead crane system, the standard M5067 coil lifter offers the most comprehensive coil handling features. The lifter can be operated with cab, pendant or remote controls. Standard coil lifter units, 20 to 50 ton capacity, include replaceable, non-metallic wear bars in the frame. Optional features are available to adapt the coil lifter to the particular needs of the coil handling system.

Special Lifter Model M5067

This customer needed a faster and safer way to lift forged rings into and out of their row of vertical turret lathes. They were lifting them manually using three chains that had to be carefully rigged and adjusted. The Bushman AvonTec lifter allows the crane operator to insert and remove rings automatically in a fraction of the time and with less chance of damaging the ring. The lifter can handle the customer’s complete range of ring sizes from a six-foot diameter solid ring to a 21-foot ring with a narrow cross section.
 

Motorized Rotating Coil Lifters, Model MR5067

The MR5067 coil lifter from Bushman AvonTec is a low headroom crane lifting attachment designed to give precise coil positioning. Rotation is accomplished by a gear motor with an integral pinion driving a geared bearing that is mounted in compression. An overload clutch protects the drive rotation from shock loading.

This Bushman AvonTec Model MR5067 coil grab has motorized rotation and a capacity of 80,000 pounds. The special design of this mill duty lifter includes motorized drop legs in a horizontal plane.

This coil grab was designed for low headroom areas and has motorized rotation.

Adjustable Coil Lifters, Model 427

This 25 ton capacity adjustable coil lifter offloads steel coils from a railroad car in Houston.

The model 427 coil lifter is especially suited for below-the-hook applications with lower duty cycles and those in which operators are in close proximity to the coil. Reliable and economical to operate, the model 427 coil lifter is very effective type of lifting equipment for use in narrow aisles.

Coil Lifters with Load Weighing Systems

Coil Grab with an integral weigh system and a capacity of 80,000 pounds.

Bushman AvonTec coil lifters can be equipped with weighing systems for automatic coil weighing during loading and unloading. The load cell is incorporated into the bail assembly. Low headroom coil grab designs are also available.

Features include:

• All electronic components that are easily replaced
• Calibration settings saved in memory that is maintained even during power outages
• High accuracy and repeatability

Hydraulic Mill Duty Coil Lifter

The hydraulically operated mill duty coil lifter moving this steel coil has a capacity of 45 metric tons.

Power Rotating and/or Telescopic Coil Grabs

These units are Mill Duty Lifters of a proven, robust, low maintenance design. They meet or exceed BTH-1 2005. They feature a torque limiter to reduce the possibility of damage to the unit and load.

These units are custom built according to the customers’ specific application and feature bobbin-style crane connections that significantly reduce wear and damage to the crane hook.

Available options include:

• Motorized or manual adjustment
• Powered rotation
• Low head room designs
• Many coil protection features
• Digital weigh system

Coil Lifter Stands

Coil lifters are large and top-heavy. They can cause significant personal injury or property damage if they fall over. When not in use, each coil lifter should be stored on a stand designed for its specific size and weight.

Coil Lifter Options

Coil Grab Option Descriptions:

1. Connection to the crane--Standard pin bail, pull-pin, low headroom, direct reeved sheaves, sister hook, pull pin bobbin.
2. Motorized rotation--The 350° stop-to-stop rotate drive has a ring gear and pinion driven through a motor reducer and slip clutch. Continuous rotation is also available.
3. Bushman AvonTec Weigh-Rite© scale system has repeatable accuracy to ± 0.1% of lifted load in 10 pound increments. Includes digital scoreboard readout on the grab or wireless modem to transmit data to remote devices such as printers, PCs, scoreboards, etc.
4. Stack lights--Various colors are available to give visual indication to the operator when limit switches have been tripped and the grab is in position to lift the coil safely.
5. Tapered legs--Legs can be tapered away from the coil to allow clearance for slightly telescoped outer coil wraps, thus reducing the possibility of coil edge damage.
6. Urethane body bumper reduces chance of coil damage if grab frame contacts top of coil.
7. Flappers--Spring loaded pivoting flapper plates trip a limit switch after contacting the coil. Leg motion stops, reducing the possibility of damage to coil edge and unnecessary wear on the slip clutch.
8. Urethane bumpers--Coil contact surfaces are covered with replaceable bumpers. Lifting saddle bumpers are recommended for use when handling cold rolled material under 0.015” in thickness, tin plate and surface sensitive materials.
9. Proximity and optical sensors can “see” the coil edge and alert operator when it is safe to close the legs to insert saddles into the coil ID.
10. Heel rollers protect coils in adjacent rows when lowering the grab into lifting position.
11. Urethane toe rollers are standard on coil grabs. Steel or aluminum toe rollers are optional extras at customer request.
12. End-of-travel switches electrically stop leg motion and can lengthen life of slip clutch.
13. Storage stand permits grab to be stored safely during maintenance and frees up the crane for use without the coil grab.
14. Motor controls--AC or DC motor controls are available to operate with local power supply voltage and frequency.
15. A sensor is mounted in one foot, as standard, to inhibit the drive when a coil is present. This sensor can also be mounted in the other foot as an optional extra.

Other options can be provided. Please consult with factory.
