EARTH-MOVING EQUIPMENT
Different excavator joints require different priorities
Bucket, trapeze, arm and boom connections vary in load, contamination and maintenance access. For each position, working diameters, axial fixation, lubrication supply and body condition are checked.
WHAT TO CHECK
Initial data on working equipment
The machine number helps identify the task, but does not replace dimensions.
Pairing
Pin, bushing, washers and body hole.
Load
Impact, cyclicity and direction of force.
Service
Lubrication point and replacement availability.
HOW THE WORK IS CONSTRUCTED
Complete inspection of pins, bushings and washers
For the repair kit, the associated dimensions and thickness of the adjusting elements are compared. For serial delivery, the part numbers are associated with the packaging markings.
Couple
Pin and working diameter of the bushing.
Axis
Washers and permissible axial clearance.
Kit
Quantity per unit or machine.
RESULT
Parts organized by machine joints
This structure is more convenient for purchasing and assembly than a general list of bushings without indicating the installation location.
- KnotPosition binding.
- NumberPart identification.
- SetCompleteness of delivery.
BEFORE AGREEMENT
From installation site to initial data set
The bucket, boom, arm and trapezoid have different geometry and joint loads. The request must indicate the specific position of the part, number or drawing, mating dimensions and lubrication method. This eliminates the transfer of parameters between visually similar pins and bushings.
Knot
Precise installation location and connection function.
Detail
Pin, bushing, washer or set with one identification.
Dimensions
Working diameters, lengths, fits and axial fixation.
Operation
Load, contamination, lubrication and maintenance.
NEXT STEP
Submit a list of excavator joints
Include part numbers, dimensions and quantities per machine or repair program.
