Durability & Heavy Duty Features

Unlike the standard SH330/SH350 models, the LHD version includes localized frame and component bracing to withstand aggressive side-loading:

• Boom & Arm: Reinforced heavy-duty plating with optimized cast arm foot boss shapes.

• Undercarriage: Long heavy-duty (LHD) chassis with reinforced side frame structures, thicker track motor case framing, and optimized track guards.

• Lubrication: EMS (Easy Maintenance System) bushings with solid lubricant embedded in high-strength brass extend standard bucket pin greasing intervals up to 1,000 hours.

• Bumper Guards: Built-in heavy-duty thick steel side bumper guards protecting the upper structure from side impacts.

Fluid Capacities

• Fuel Tank: 580 liters

• Hydraulic Fluid Tank: 175 liters (System capacity: 350 liters)

Operating Modes

Controlled easily via the in-cab 7-inch high-definition color LCD monitor:

• SP Mode (Super Power): For maximum production and heavy-duty tasks (increases cycle speed by 10% over older models).

• H Mode (Heavy): Best balance between heavy-duty output and optimized fuel consumption.

• A Mode (Auto): For lighter-duty jobs, versatile digging, and utility work where fuel conservation is the main priority.
