How to choose a second-hand loader？

First, Appearance. Check To See If There Is A Painted Car, And Pay Attention To Matching The Car Number, Engine Number, Frame Number And Bridge Number. Under Normal Circumstances, The Numbering Dates Of Each Component Will Not Be Too Long Apart, Generally No More Than Three Months. If It Is Longer Than That, It Is Necessary To Consider Whether It Was Refurbished And Assembled.

The Second Point Is The Frame. Carefully Check The Front And Rear Frames For Cracks, Welds, Paint Repairs, And Deformations. If There Is, Check Whether It Is An Important Location, Such As The Joints Of Parts, The Welding Of The Frame, Etc. If You See Any Doubtful Areas, Touch Them With Your Hands. Sometimes Cracked Areas Are Polished And Repaired. You May Not Be Able To See It With Your Eyes, But You Will Definitely Feel It When You Touch It With Your Hands.

Also, Adjust The Throttle Of The Engine Equipment To The Maximum, Lift The Bucket, Run In A Straight Line On Flat Ground, And After Applying The Brakes, Check Whether There Is Vibration And Beating At The Hinge Pin. If The Beating Is Severe, The Vehicle May Have Exerted Too Much Force. How To Feel The Amount Of Movement? You Can Feel The New Machine For Comparison, So That You Have An Idea.

The Third Point Is To Look At The Tires. Loaders That Are Used In Harsh Environments For A Long Time Often Suffer Greater Wear And Tear, And The Wear Of The Tires Will Also Be Very Serious. The Tires Themselves Are More Expensive, So Many People Do Not Replace The Tires When They Are Sold. In This Regard, The Loss Of The Rebel Loader Is Relatively Accurate Through The Wear Of The Tires.

When Purchasing, If You Find That The Tires Of The Loader Are Seriously Worn D 01:32, Then Everyone Must Pay More Attention. This Kind Of Loader Is Likely To Have Greater Wear And Tear During Operation, And You Need To Do In-Depth Research On The Use Of The Components. Good Judgment. Also, Don’t Just Look At The Age Of The Tires. The New Ones May Be Fully Retreaded Tires. Look At The Brand Of The Tires And Make A Note Of It Before Checking.

When Fully Retreading A Tire, Pay Attention To The Surroundings Of The Steel Rim. In The Gap Between The Tire And The Steel Rim, Genuine Tires Are Relatively Smooth And Neat. Retreaded Tires Are Generally Not Smooth And Neat. Half-Retreading Tires Are More Visible And Obvious. Japanese Tires Should Check Whether There Are Holes In The Teeth, Whether The Size Of The Holes Is Patched, Etc.

The Fourth Point Is The Hydraulic Tank. Open The Oil Filler Port And Smell If There Is A Burnt Smell. If There Is Any Smell, It Means The Temperature Is Relatively High. Use A Ruler To Put A Drop Of Oil On The White Non-Reflective Paper To See If There Is Aluminum Alloy Powder. If There Is, It Means There Is A Problem With The Turbine. It Is Normal. The Oil Should Be A Clean, Slightly Red Stain.

The Fifth Point Is To Check Whether The Engine Appearance Is Clean, Whether There Is Any Oil Leakage, And Whether It Starts Sensitively. There Should Be Slight Blue Smoke When Starting The Cold Cylinder, No Blue Smoke From The Hot Engine, Slight Black Smoke From The Gas Pedal, Normal Exhaust, And Basically No Smoke. If There Is Smoke, It Should Be White. If There Is Blue Smoke, Be Careful.
Another Little Experience Is To Check Whether The Engine Coolant Is Water Or Antifreeze. Car Owners Who Add Antifreeze Take Good Care Of Their Machinery. If Possible, Disassemble The Air Filter To See If The Air Intake Is Clean. The Air Intakes Of Well-Protected Machines Are Very Clean. You Can Also Use The Sealant To Determine Whether The Engine Has Been Repaired. You Need To Look Carefully Or Use A Light To See This.

The Sixth Point Is To Look At The Bucket. The Bucket Is The Most Severely Worn Part In The Work Of A Loader, But It Is Also The Most Important Working Device. Therefore, In Order To Ensure That The Loader Can Be Put Into Good Use, Everyone Must Strictly Check The Wear Of The Bucket, Judge The Age Of The Vehicle, And Avoid Choosing A Loader With Poor Quality. When Selecting, You Should Look At The Thickness Of The Blade, Whether The Side Plate And Bottom Plate Are Deformed, And The Thickness.

The Seventh Point Is To Look At The Water Tank. The Water Tank Must Be Completely Cleaned On A Car That Has Been Filled With Water For Three Years, Otherwise The Heat Dissipation Will Be Poor. If The Water Tank Is Damaged And Blocked By Scale And Is Tilted, The Water Tank Will Leak As Soon As The Scale Is Washed Away.

Point Eight, Look At The Gearbox. Confirm The Problems With Gearbox Oil And Other Gear Oil Pressure To Ensure That The Gearbox Works Effectively And Avoid Some Losses In Effectiveness And Efficiency. In Addition, While Performing Gearbox Testing, Some Testing Should Also Be Done On The Loader’s Working Pump To Avoid Serious Wear And Tear, And To Prevent Problems Such As The Loader’s Possible Slow Boom Lift.

The Ninth Point Is To Look At The Hydraulic System. To See If The Operation Is Smooth, Do A Single Movement D 04:23 And Hold It To Death To See If The Engine Stalls. If There Is Oil Leakage At The Connection Point Of The Fuel Door Pipe At Total Speed, Check The Hose Of The Entire Machine. The Hose Will Generally Crack In Two To Three Years. If All The Hoses On The Entire Machine Are Full Of Cracks, Especially Those Under The Cab That Are Not Exposed To Wind And Sun, You Must Be Careful.
