FUNCTIONS OF SKID LOADERS
🔸 Rearranging bulk cargo for better hold space utilization
🔸 Gathering material in a favorable position for the “grab” to facilitate unloading (reaching)
🔸 Final positioning of cargo according to the cargo plan (coils, sheets, profiles, etc.)
🔸 Performing lifting of light loads to optimize space
FUNCTIONS OF EXCAVATORS
🔸 Breaking up bulk cargo conglomerates to make it easier to handle
🔸 Applying vibration to loosen cargo from the bulkhead and hold structures
🔸 Performing lifting of light loads to optimize space
LIFTING
🔸 In certain types of loading/unloading operations, the use of wheeled machines is intense, and a specific rigging plan must be developed for each type of machine.
🔸 Manufacturer instructions must be followed, and lifting points must be clearly identified.
🔸 Some manufacturers do not detail the lifting method. This evaluation should be included in the rigging plan.
🔸 Movement must be closely supervised, as there will often be personnel inside the hold.

Rigging Plans for Routine Lifting. “Routine” does not always mean “simple.”
LIFTING
🔸 One of the methods for unloading bulk solids is through the use of specific devices called “grabs.”
🔸 They are typically lifted by the ship’s onboard cranes on bulk carriers.
🔸 Weighing 8 to 10 tons themselves, they can lift a net load of up to 15 tons, totaling 25 tons of gross weight.
🔸 In common bulk carriers, the onboard cranes have a capacity of 25 tons when operating with the “grab” and 30 tons when handling other loads.
🔸 It is very important to assess the specific weight of the material being lifted to avoid overloading the crane, as there is a large variation in solids that can be cargo.
