2. Highlighted Features

2.1 High Efficiency & Outstanding Fuel Economy

It is matched with Komatsu's proprietary HydrauMind closed-center load-sensing hydraulic system (CLSS), which dynamically adjusts oil flow distribution according to actual operation demand, eliminating unnecessary energy loss. The built-in ECO working mode reduces fuel consumption by 12%~15% compared with the previous generation PC110-6, without compromising output power. The auto idle function further cuts fuel waste during standby periods.

2.2 Heavy-duty Durability

The boom, arm and undercarriage frame are all made of high-tensile strength steel, with all welding joints passing strict stress testing to resist impact and deformation under heavy-load or rough working conditions. The track shoes, carrier rollers and idlers adopt wear-resistant forging technology, extending their service life by 20% compared with other products in the same tonnage class. The X-type undercarriage structure also provides excellent stability during lifting or slope operation.

2.3 Operator-centric Cab Design

The cab is ROPS (Roll-Over Protective Structure) and FOPS (Falling Object Protective Structure) certified, ensuring operator safety in high-risk scenarios. It is equipped with a fully adjustable shock-absorbing seat, a high-performance air conditioning system with multi-directional vents, and a fully sealed design that limits interior noise to only 72 dB(A). The ergonomic control levers are light to operate, and large panoramic windows minimize operation blind spots.

2.4 Low Maintenance Cost & Smart Management

All daily inspection points (engine oil level check, filter replacement, coolant check, etc.) are designed to be accessible from the ground, shortening pre-operation inspection time. The standard Komatsu KOMTRAX remote monitoring system supports real-time tracking of equipment location, working hours, fuel consumption and fault codes, and sends active maintenance reminders to help fleet managers reduce operation costs effectively.

3. Main Application Scenarios

Urban municipal construction: Trench digging for water/gas pipelines, road repair, public facility construction
Landscaping: Site grading, tree pit digging, pond excavation, landscape shaping
Small earthmoving projects: Foundation excavation for small residential buildings, earth transfer on small sites
Narrow-space operation: Auxiliary work in large construction sites, tunnel construction
Agricultural infrastructure: Irrigation canal digging, farmland leveling
Light demolition: Low-rise building demolition, concrete breaking when equipped with a hydraulic breaker

4. Optional Configurations

Multiple bucket options: Heavy-duty rock bucket, narrow trench bucket, grid bucket
Work attachments: Hydraulic breaker, hydraulic shear, log grapple, auger
Auxiliary devices: Quick coupler for fast attachment replacement, rubber track pads (to avoid damaging asphalt roads), extra working lights for night operation, reverse camera, heated seat for cold regions
Customized versions: High-altitude adaptation version, cold-region anti-freeze version, tropical heat dissipation version

5. Market Reputation

The PC110-7 is widely recognized globally for its high reliability, low operation cost and high residual value. Supported by Komatsu's complete global after-sales network and accessible spare parts supply, it has become one of the most popular 11-ton class excavators for small and medium-sized construction contractors.
