    Sir, let me ask you a question not related to this particular problem is more like a general knowledge question, here it is (What is the maximum rope/cable/line length for a particular TLL crane? Sorry if my quiero is confusing but if you can understand and answer it it would be great, I always watch your videos I find them very informative how you explain step by step

    • @SafetyProCalculations
      @SafetyProCalculations 21 วันที่ผ่านมา

      Hello. Thank you for your question. There is not a single answer. It all depends on the crane and how it is configured. If you are asking about the maximum tip to ground distance (Length of rope from boom tip to ground)that can be determined from the range diagram and is dependent on boom length and angle. If you are asking about the total length of rope that can be on the crane that is a function of rope diameter and drum capacity-manufacturer’s documentation (manuals) will provide that information. Going to be different for every manufacturer and every crane model. A large Liebherr is going to be different the a link belt RT. I hope this helps.

    What if it was a 12 hour work day, but an employee was only performing abatement for 85 minutes of the day?

    • @SafetyProCalculations
      @SafetyProCalculations 27 วันที่ผ่านมา

      There are adjustments (correction factor) for workdays exceeding 8 hours. Should be covered in the video. Also for some substance there are published exposure limits for 10 hr workdays. Record zero exposure for part of the workday not involved in abatement activities. If abatement involves lead or asbestos I encourage you to review OSHA guidance for exposure to those substances.

    How to calculate 500 ton cranes outrigger pressure psi each outrigger.

    • @SafetyProCalculations
      @SafetyProCalculations 6 หลายเดือนก่อน

      Pressure equals force divided by area. Weight of the crane and load divided by the total area of the contact surfaces. Divide that by the number of outriggers. Pressure will not be equal on all outriggers at same time. If loaded boom is positioned over an outrigger the pressure on that outrigger will be greater.

      Block is a deduction. When calculating net capacity the weight of the block is deducted from the gross capacity. Doesn't matter if line pull or chart capacity is being used as gross capacity.
