"This manual has been made to provide users with information and instructions for the XXX Grab Carrier.

In the manual you will find descriptions of the equipment, and instructions for transporting, assembling, operating and servicing it.

(...)

The XXXX fitted with a HDSG hose reel assembly and hose guide wheels is designed and intended only for operation with a grab and for the purpose of making excavations in the ground.

Using the equipment for other work such as levelling of soil, lifting and moving of load or persons, or dragging of load, is not permitted. Neither may the equipment be used in areas where there is a risk of explosion.

(...)

The grab carrier uses almost exclusively bolts of the 8.8 tensile strength classification."

¿Podría ser algo así como 'transportadora de oruga(s)'?
