Section 3 – RATED TOTAL LOAD CHARTS Mini-Crawler Crane M A E D A
3-22 1/2019 MC285C-3
Rated Total Load Chart for Auxiliary Winch
1. The diagram of working radius and lifting height has been made allowing for no deflection in the
boom.
2. Rated total load chart is based on working radius with boom deflection and raised load taken into
consideration.
3. Rated total load is shown with the mass of single fall hook (20 kg) included.
4. If boom (3) is extended to any extent, work should be performed within the capacity for “5.575 m
Boom”.
5. When more than one half of the first mark is exposed from the boom (2), work should be carried
out within the performance for the “7.075 m Boom”.
6. When more than one half of the second mark is exposed from boom (2), work should be carried
out within the performance for the “8.575 m Boom”.
7. Rough operation of crane is very dangerous. Always try to operate safely.
8. The Rated Total Load Chart capacities are based on using the factory supplied Standard Wire Rope.
If you replace the wire rope, use the correct specification, that meets or exceeds the standard wire
rope strength and specification.
9. Standard wire rope specification: 6xWs (26) IWRC, 8 mm diameter, 108 m
Specified breaking load: 48.1 kN
