Lifting attachments and crane attachments

Various kinds of lifting attachmentss are used with types of lift cranes to perform the material handling tasks. In today’s operational guide of lifting attachmentss, the general procedures on lifting attachmentss installation, inspection, maintenance and repairs, operation, and lifting crane operator training, etc.

lifting attachmentss also called the below-hook devices are used with various types of lifting equipment, such as, lifte cranes, electric hoists, trolley and other types of lifting cranes and hoists, etc. As one of the lifting crane parts, lifting attachmentss are directly influences the lifting efficiency of the lift cranes. Therefore, the lifting attachmentss operation guide is presented, hoping it is useful.

Generally, the below-hook devices can be grouped according to the supporting, indentation type pressure gripping or friction type pressure griping, etc. In the following, different types of lift devices will be presented for your references.

The general operational guide for lifting attachmentss are presented for your references which are used with the instruction manuals of the lifting attachmentss and lifting cranes given by the manufacturers. Any doubts or problems should be solved by consulting the lifting attachmentss manufacturers and lift crane manufacturers or you can leave a message below.

 Warning before lifting attachmentss installation

The potential hazards of using lifting attachmentss could not be solved solely be mechanical means which requires the attention, care and common sense of lifting crane operators, and the safety supervisor who has been trained on the lifting attachmentss and lift cranes. 
The crane attachments operational guide can not be the substitute of your crane attachments manual which is offered as general guide to help in the pursuit of efficient operation of lifting attachmentss.

Design modifications of crane attachments should be performed according to the full understanding and approval of the manufacturer or it may cause danger and resulting in danger. 

Markings of crane attachments

The nameplate of crane attachments should have the following information:

• The name and address of the crane attachments manufacturer.
• Serial number of the crane attachments.
• Rated load capacity.
• Each nameplate of the lifting attachmentss should be located on the place where the lifting capacity is visible to every side of the lifting attachmentss and on the lifting cranes.

crane attachments tags should include the following information:

• Read the operation before operating.
• Inspect the lifting attachmentss each shift before operation.
• Lifting loads according to the safety instruction.
• Overloading is prohibited.
• Don’t use lift devices for handling loads beyond designated range.
• Don’t use the lift devices without the marks of capacity, weight and safety.
• Don’t make alterations or modifications.
• Don’t lift load higher than necessary or leave it suspended unattended.
• Do not remove or obscure the warming label.

Note: All warning labels should be maintained visible and legible and replace as necessary.

Crane attachments installation

As one of the lifting crane parts, the lifting attachmentss should be assembled and installed on the lifting cranes according to the instruction. 
Attention: 
When the crane lifting attachmentss operation needs extra power supply, the power source must be matched with the requirements, which also should be connected with the line side of the lifting crane disconnect switch or an independent circuit as specified in the manufacturer’s operating instructions.

Crane lifting attachmentss inspection

lifting attachmentss should be inspected before any crane lifting operation and regularly inspections is also needed to reduce crane lifting hazard and risk.

Initial inspection of crane lifting attachmentss

Before operation, all the lifting attachmentss should be inspected by professional inspector according to the instruction of manufacturer’s. 
Frequent in service inspection 
Depend on the types of crane lifting attachmentss, regular inspection should be conducted daily, weekly or according to the manufacturer’s instruction. During inspection, deficiencies to look for include but not limited to:
1. Crane lifting attachmentss of structural deformation. 
2. Cracks or distortion in the structural frame, hoist-hook attachment points, attached slings, cracks in welds, mechanically operation parts, clevises or hooks. 
3. Malfunctions during the lifting attachmentss operation. 
4. Wear of hoist hook devices, pins, slings, linkages or load supporting clevises or mechanical parts.

Periodic in service inspection

Crane lifting attachmentss should be inspected by professional inspector according to the manufacturer’s instructions monthly and yearly to check whether parts have worn beyond the limits.

Attention:

1. Out of service tag should be tagged on the lifting attachmentss once any deficiencies are detected. 
2. Power should be disconnected at source before servicing and follow lock out/tag out procedures to avoid danger of electrocution.

3. The lifting attachmentss should not go on operation until the repairs has been finished. 
4. All the inspection and maintenance procedures should be recorded timely.

Maintenance and repairs of lifting attachmentss

Maintenance

A preventative maintenance program should be established for each and every crane lifting attachmentss based on manufacturer’s recommendations.

Repairs

Crane lifting attachmentss repairs should be conducted by qualified person. Also all the crane lifting attachmentss repairs and modifications should be performed by or under the direction of the lifting crane manufacturer.

Attention:

1. All the repaired crane lifting attachmentss should be operationally tested. And load test is also needed before being returned to services.
2. All the repairs and parts replacements should be filed on dates.

Crane lifting attachmentss operation

Crane lifting attachmentss should be operated by professional lifting crane operators, who should be well trained and know well about the lifting crane devices, crane lifting operation, crane lifting safety and others, etc.

Operator training

Crane lifting attachmentss should be operated according to the manufacturer’s operating instructions. Crane lifting operation should be in according to the principles and rules in the manufacturer’s guidelines. Crane lifting safety training should include:

• Details of lifting cycle
• Application of lifting attachmentss to the load.
• Any special operations may need extra instruction and precaution may be required.
• Recognition of proper load configuration.
• Before assuming responsible for using the lifting attachmentss, lifting crane operator should show their understanding of the crane lifting sequence and procedure to their crane trainer who will record the performances of the each operator.

Operating practices

• Lifting crane operator have to make sure all loads are secure and no crane lifting hazard is caused during the lifting cycle.
• Crane operator have to closely monitor the crane lifting attachmentss performances during lifting crane operation.
• Stop the lifting attachmentss immediately in any improper performance occurs.
• Standard hand signals for lifting crane operations should be well known by the crane operator.
• Crane operators have to follow the signals from the designated person only.
•  Lifting crane operator has the responsibility to make sure the loads in the right conditions for lifting.

Lifting loads handling

• Crane lifting attachmentss must not be used to handle loads over the rated lifting capacity.
• The total weight of the lifting attachmentss and loads should not exceed the rated lifting capacity of the lifting crane and hoist.
• Crane lifting attachmentss should be used to handle loads within the handling loads range in accordance with manufacturer’s recommendation and lifting crane sequence and procedures.
• Crane lifting attachmentss should be in the right condition for material handling.
• Crane lifting attachmentss should not touch obstructions.
• Lifting crane operator and other personals should stay away from the lifting attachmentss safely.
• Never ride or allow people to ride on a lifting attachments.
• Check the balance of loads before lifting by making a preliminary lift of a few inches.
• Do not slide the lifting attachmentss or loads across any surface.
• Sudden starts and stops should be avoided. All loads should be accelerated or decelerated smoothly.
