JS120 is the most fuel-efficient 12 Tonne Excavator in the industry which not only delivers 8%* improved output tonnes per hour but also makes way for savings up to Rs 2 Lakhs per year*. With a maximum operating weight of 12,800 Kgs, JS120 has got the bucket capacity of 0.5-0.65 cum. The 12 Tonne JCB Tracked Excavator has a maximum Engine Power of 60kW which results in a power packed performance across various industries. A perfect companion as a Construction Excavator, JS120 is also an ideal working partner for quarry, roads, brick industry, and civil construction etc.

Especially designed for carrying out activities as a construction Excavator, JS120 is manufactured at the state-of-the-art manufacturing plant at Pune with the latest innovative technology. This Hydraulic Excavator consists of a durable upper frame, heavy duty X-frame, reinforced boom, strengthened arm, hard faced bucket, and IP67-69 dust & water proof connectors for high reliability of electricals.

With hydraulic oil change interval of 5000 hrs and choice of Productivity (P) & Economy (E) modes, this JCB Tracked Excavator is extremely easy in serviceability and low on maintenance. The Economy Mode is for fuel saving with an optimum productivity and Productivity Mode is for an improved productivity through pump flow when higher output is required. Loaded with a special filtration system and an auto idler, JS 120 offers reduction in maintenance costs and fuel savings at higher speed.

Powered by JCB ecoMax Engine, the Excavator ensures high power, long life, along with low noise and vibration. In addition to all this, it also offers an unmatched operator comfort with a spacious cab with high head and leg room, an increased seat recline for better comfort and ergonomically placed operator controls to minimise operator fatigue.

JCB is first in the industry to offer an Advanced Telematics Technology - LiveLink in a 12Tonne Excavator. This technology lets you keep a real time track of your machine’s performance and health. With multiple service reminders, health alerts, machine utilisation report and location updates, you can stay in command 24X7.
