Two new Cat Next Generation wheeled excavators – the Cat^® M314 and M318 – feature multiple design updates that boost machine efficiency and lower long-term operating costs. Advanced hydraulics more efficiently power attachments, including Cat tiltrotators to increase machine flexibility at the jobsite.

The Cat^® 352 UHD Ultra High Demolition excavator is designed to handle difficult demolition of tall structures using a range of Cat demolition attachments, including multi-processors, grapples, shears and hydraulic hammers with the retrofit boom. The UHD front can be switched for a straight or bent (retrofit) boom position for lower-level demolition and earthmoving applications. This switch typically is done in about 15 minutes with 2 people with no special tool required. The 352 UHD features a variable-gauge undercarriage (hydraulically activated), as well as the Cat Active Stability Monitoring system, which continuously informs the operator of work tool position within a safe working range and warns when approaching stability limits.

The new Cat^® trolley assist system for Cat electric drive mining trucks is now available for mining operations seeking a means to reduce carbon emissions, lower fuel and engine costs, and boost speed-on-grade for greater productivity. The Cat trolley assist retrofit kit is currently available for the 795F AC truck, and the trolley design is compatible with the three other Cat electric-drive mining trucks—794 AC, 796 AC and 798 AC.
