Performance Overview

 

1. High performance:

 

• 3 74 It can load up to 33 trucks with a load capacity of 36 metric tons （40 short tons） per hour.

• The rotational torque is increased by 10% and the cycle time is shorter compared to the previous series.

• The new static hydraulic reverse cycle makes multifunctional operations smoother and more efficient.

• The enhanced load lifting mode increases system pressure and helps you lift and place heavy materials with ease.

• The arms, poles and racks are twice as durable as the previous series, delivering reliable performance for years in the toughest environments.

• Available in three operating modes, the excavator is suitable for a variety of types of work: powerful, intelligent and fuel efficient.

• Advansys™The shovel teeth improve the penetration capacity and shorten the cycle time. A simple lug wrench, rather than a hydraulically powered impact hammer or special tool, can be used to quickly change the tips for improved safety and extended uptime.

• Auxiliary hydraulic options give you the versatility you need to use a wide range of Cat tooling.

• Perfect for temperature challenges and safeguard your normal work.The excavator has a high temperature operating capability of 52 ° C (125 ° F) and a standard cold start capability of -18 ° C (-0.4 ° F).

 

 

2 . Increasing efficiency and productivity with Cat technology :

• Standard equipment。Product Link™Machine location, machine hours, fuel consumption, productivity, idling time, diagnostic codes, and other machine data can be provided via the VisionLink online interface to help you improve shop floor efficiency and reduce operating costs.

• You can use the remote troubleshooting feature to contact agent service professionals at any time to help resolve your issues and get back to work quickly.

• The remote refresh function runs as planned, ensuring that the machine software remains up to date, thus optimizing performance.

 

 

3. It's easy to do:

 

• The engine can be started by button , Bluetooth key card or unique operator ID function .

• Each joystick button is programmed using the operator ID, and programmable items include power mode, response and control mode; The machine remembers these settings and calls them every time you operate the machine.

• The automatic hydraulic oil preheating function allows you to work faster in cold weather and helps extend the service life of your components.

• High resolution 254mm (10in) standard touch screen monitors or knob controls allow rapid navigation.

• Don't know how a particular function works or how to maintain an excavator? The operator manual is accessible at any time with a touch of the finger on the touch screen monitor.

• The Cat single handle makes it easier to control the movement of the digging machine. With the press of a button, you can control driving and steering with one hand without having to control the steering lever with both hands or both feet on the pedal.

• Do you need more motivation during work? Turning on the automatic load boost gives you an accurate 8% more power when you need it.

 

4 . Working comfortably in a brand new cab :

• It is equipped with automatic temperature control and heating seats . It can work all year round .

• With the flip-up left console, you can get in and out of the cab more easily.

• The advanced rigid base reduces vibration in the cab by up to 50 per cent compared to previous excavator models.

• The controlled devices at hand are all located in front of the operator, making it easy for the operator to control the excavator comfortably.

• There is plenty of parking space under and behind the seats, overhead and in the control room to easily store your gear.

• Connect personal devices and make hands-free calls easily with a standard wireless USB port and Bluetooth ® technology.

 

 

5. Lower maintenance workload:

• Due to reduced hydraulic oil capacity and longer , synchronized maintenance intervals , maintenance costs are expected to be up to 20 % lower than with the 374F

• The excavator has a built-in set-aside installation point, which makes it easy to add an automatic lubrication system at any time. The automatic lubrication modification kit, which is equipped, provides additional fasteners for the installation of lubrication pumps and piping shields.

• The filter life and maintenance cycle of the excavator can be tracked through a monitor in the driving room.

• Replace the fuel filter synchronously every 1000 hours; The replacement can be completed from the upper platform.

• The dust containing capacity of the new inlet filter is twice that of the old inlet filter.

• The new hydraulic oil filter provides better filtration performance, and the reverse drain valve keeps the oil clean when the filter is replaced at a time of 3,000 working hours, giving a longer service life - 50% longer than previous filter designs.

• The new highly efficient hydraulic fan has an automatic reverse function that eliminates debris on the core and does not require the intervention of the operator.

• The S · O · S sampling port simplifies maintenance and enables quick and easy oil sampling for analysis.

 

6. Higher security:

 

• A rear view camera is optional.Upon upgrading to 360 ° view, you will be able to easily view objects and people around the excavator in a single view.

• The 360 ° high-quality lighting components and 1800 lumen lights on the chassis, cab, arms, sides and back provide a complete view of the machine.

• Maintenance of the jagged steps and slippery perforations on the platform help prevent slips.

• The steering direction indicator helps the operator understand which direction to activate the steering lever.

• Thanks to smaller cockpit columns, wide windows and a flat engine casing design, operators have an excellent view on both the inner side of the ditch, in every turning direction and behind.

• Once activated, the ground downtime switch will completely stop the delivery of fuel to the engine and shut down the machine.
