Crawford  DL6021T Heavy Duty Teledock

The Crawford DL6021T teledock 100 kN is the optimal efficiency solution in general industry and logistics applications. The telescopic lip precisely bridges the gap between the ramp and the lorry bed. The Crawford DL6021T teledock 100 kN system meets the standard demands of most loading operations and fully complies with rules and regulations of the European Standard EN 1398.

Operation is based on an electro-hydraulic telescopic lip, controlled by a semi-automatic control unit. When the dock leveller is raised, the lip extends and the leveller lowers gently onto the lorry bed. After loading or unloading, the leveller is raised again, the lip retracts and the platform returns to its parking position, i.e. to ramp level.

Paint classes:

If the dock leveller is to be used in a rural area, the standard finish is:

  • Paint class 1; 80 µm factory painted for corrosive category C2 M.

If the dock leveller is to be used in an urban or industrial atmosphere, or in a coastal area, it may be appropriate to select an alternative paint class with increased resistance to corrosion C3 M.

  • Paint class 3; 160 µm factory painted for corrosive category C3 M.

To increase corrosion protection to C4 for saline coastal areas or C5-I for aggressive or humid atmospheres, the dock leveller can be delivered with hot dip galvanized (80 µm) steel parts.
