What to do with defective cranes?

Unfortunately, it is not always possible to avoid disruptions occurring with a rented crane during its use on the construction site. Errors in crane controls, torn crane ropes, or failure of the drive and lifting gear brakes are defects that must be reported immediately. If safety is also at risk, then defective cranes should be taken out of service until the damage is repaired. First and foremost, this means: interrupt the construction project and report the damage immediately.

What disruptions can occur on a crane?

Cranes are complex machines that require a lot of expertise. Accordingly, disruptions of any kind can occur. The most common include:

Severe damage, immediate shutdown required:

  • Failure of the drive and lifting gear brakes: In this case, operation must be stopped immediately. Contact us right away and we will send a technician to your construction site to handle the damage.
  • Breakage of a running wheel: If the running wheel breaks, take the crane out of service immediately. Contact us and we will send someone to repair the damage.
  • Cracks in load-bearing crane components: In this case too – take the crane out of service, contact klarx
  • Formation of rope knots: In this case, the rope must be replaced immediately. Contact klarx and we will send a technician to your construction site.

Minor damage, problem can possibly be solved via phone

  • Disruptions in crane controls: A disruption in crane controls can have many causes; this problem may possibly be resolved immediately by phone. Call your klarx expert and we will try together to find the cause of the disruption. If this is not possible, you will receive on-site assistance.
  • Overflow of a crane rope over a winch drum flange: This damage can possibly be easily resolved via phone. Contact your klarx expert in this case as well.
  • Breaks and/or cracks in load attachment devices: If the crane operator is trained to handle disruptions, he can repair this damage on site himself.

Defect on crane reported – what now?

Once you have reported the defect on the crane and taken photos of the damage, you should secure hazard areas depending on the severity of the defect. Switch off the main switch, disconnect switch, or similar, and wait for further instructions. You are only permitted to perform maintenance work yourself if you are professionally qualified to do so. Otherwise: leave the construction site properly.
