※ Note
1. Lifting capacity are based on SAE J1097 and ISO 10567.
2. Lifting capacity of the ROBEX series does not exceed 75% of tipping load with the machine on
firm, level ground or 87% of full hydraulic capacity.
3. The lift-point is bucket mounting pin on the arm (without bucket).
4. *indicates load limited by hydraulic capacity.

※ Lifting capacities are based upon a standard machine conditions.

Lifting capacities will vary with different work tools, ground conditions and attachments.
The difference between the weight of a work tool attachment must be subtracted.
Consult your Hyundai dealer regarding the lifting capacities for specific work tools and attachments.
Failure to comply to the rated load can cause possible personal injury or property damage.
Make adjustments to the rated load as necessary for non-standard configurations.

 4) SELECTION OF TRACK SHOE
Suitable track shoes should be selected according to operating conditions.
Method of selecting shoes
Confirm the category from the list of applications in table 2 2, then use table 1 to select the shoe.
Wide shoes (categories B and C) have limitations on applications. Before using wide shoes,
check the precautions, then investigate and study the operating conditions to confirm if these
shoes are suitable.
Select the narrowest shoe possible to meet the required flotation and ground pressure. Application
of wider shoes than recommendations will cause unexpected problem such as bending of shoes,
crack of link, breakage of pin, loosening of shoe bolts and the other various problems.
