Why should the spreader be tested regularly?
In accordance with the provisions of the relevant laws and regulations of spallers, tools used for lifting shall be tested by professionals at least once a year.
During the use of the spreader, the following factors may cause damage to the spreader and bring potential safety hazards:
1. Scratches, wear and deformation of the spreader surface during the use of the spreader;
2. The impact load of spreader during lifting (because of this, the safety factor of spreader is often relatively large);
3. Fatigue damage of spreader;
4. Surface damage, deformation, wear, corrosion and rust caused by non-standard operation and maintenance.
The above factors may lead to the damage of the spindles. If the spindles are not inspected regularly, these potential safety hazards may not be found and thus lead to accidents. Therefore, regular inspection can greatly reduce such potential safety hazards and ensure safety.
