Can a load weighing 1890kg be raised with the mast in the vertical position?

To determine whether a load weighing 1890 kg can be raised with the mast in a vertical position, one must consider the lifting capabilities of the specific forklift being used, including its rated capacity at different lift heights and load centers. When the mast is vertical, the forklift's stability comes into play, and the ability to safely lift a load also depends on factors such as the center of gravity and the design of the forklift.

The correct answer affirms that it is indeed possible to raise a load of this weight with the mast in the vertical position, provided that the forklift is rated to handle such a load under those specific conditions. Each forklift model comes with operational guidelines and specifications indicating the maximum weights and conditions under which loads can be lifted. Therefore, if the forklift model in question has a capacity rating that supports lifting 1890 kg with the mast vertical, then it is safe and permissible.

The other options suggest varying conditions or limitations that would imply restrictions on lifting the load. However, as long as the forklift is appropriately rated for the weight and the operating conditions are safe, lifting with a vertical mast can be achieved without the need for additional attachments or considerations about load center as long as it falls within the forklift's operational specifications.
