Caterpillar Suspension Mount - Part 211-4987

Part 211-4987 (cross-reference: 138-9224) is a rear suspension mount for Caterpillar articulated dump trucks. This critical component is used on the CAT 735, 740, 740GC, and 745 series ADTs as well as the D350E II and D400E ejector trucks. Dimensions are 7.97 inches height with an 8.66 x 8.66 inch base footprint and 0.87 inch mounting holes. The mount absorbs extreme shock loads encountered during off-highway haul road operation while supporting payloads up to 45 tonnes. The 211-4987 supersedes the earlier 138-9224 part number. CAT 735/740/745 series articulated trucks are among the most popular in US mining and heavy construction operations. HAMM Mount offers this as a direct OEM-replacement at significant savings compared to the CAT Parts Store pricing.

Manufactured by HAMM Mount in our ISO 9001:2015 certified facility using advanced vulcanization technology and premium rubber compounds. Every unit undergoes multi-stage quality control including dimensional inspection, hardness verification, and load-deflection testing. Fire safety compliance per EN 45545-2 is verified for all railway applications.
