CAT Next Generation CAT®312 GC Hydraulic excavator
Product Feature
The performance is reliable and durable
● C3.6 The engine and the electro-hydraulic system can be operated synchronously.,Allows you to move large quantities of material without using excessive amounts of fuel,And C3.6 Comply with China's third national emission standard for off-road vehicles。
● Swing drive has been redesigned,The rotation torque and stability can be improved.,Thereby improving productivity。
● Chassis system is optimized by design,Allows you to work in tight areas with ease。
● The new main hydraulic pumps are electronically controlled,Greater efficiency can be achieved,And provide a higher flow rate than previous models.,Thereby improving control ability and productivity.。
● Jib、The stick and the bucket linkage are carefully designed,Maximizes durability。
Reduce cost of ownership and operation
● Three operating modes available,Power can be selected according to the specific job:Intelligence,Power can be automatically adjusted according to demand;Save fuel,Fuel consumption can be reduced;Strong,Achieve maximum productivity。
● 312 GC Designed to simplify maintenance and reduce maintenance costs,Reduce costs by up to 20 percent%。
● Extended service life of hydraulic and air filters,The pilot filter and the case drain filter have been eliminated。
● Most routine maintenance can be done above ground.,Thereby reducing the time spent on routine tasks。
● The swing drive runs on the hydraulic system,There is no need to check or fill a separate oil system。
● Refill of hydraulic oil and engine oil is reduced,No change in performance or service life。
● When hydraulic demand is low,Automatic engine control(AEC,Automatic Engine Control)The system will reduce the speed,This reduces your fuel costs。
● Cat Product Link™ The system is standard,So you can go through the VisionLink® Remote monitoring of fuel consumption、Machine health、Location and hours of operation。
The operation is simple
● Push-button start engine for easy operation。
● Using the One-Touch Joystick(With adjustable joystick response and gain),Easily controlled by any operator。
● By high resolution 203 mm(8 in)Simplified control menu on touch screen monitor,Enables fast navigation。
● New Shallow Slot Bucket Option Helps You Handle Soft、Wet and sticky material。
Easy to maintain
● Almost all major mechanical components can be serviced from the ground or from a service platform。
● The radiator screen can be easily removed,Easy to clean,And small debris that is difficult to remove from the heat sink can be eliminated,Uch as grass clippings。
● Easy access to the engine compartment from the service platform;Easy access to the oil cap and level gauge,And the automatic tensioner ensures that you do not need to adjust the belt。
● Cat Technology to help you monitor your machine,And Caterpillar Service network helps you maximize uptime。
Greater security
● Ground level access to most routine maintenance point。
● The emergency engine and electrical shutoff are also accessible at ground level。
● The armrest is consistent ISO 2867:2011 Requirements;Skid plates with countersunk bolts for steps and landings,Protects against slipping and tripping。
● In case of emergency,The operator can climb out of the machine through the rear window or the steel sunroof。
● The new cab is designed with larger windows and smaller cab columns,Provides excellent visibility inside the trench and in all directions。
● Bright exterior LED Lights and optional rear view camera,Make sure you know what's going on around you at the job sit。
