1
No leak-proof design for quick coupler, hydraulic oil drips and pollutes the site during attachment change, requiring extra cleaning time.
Clean time -15min/shift
2
Breaker pipelines not internally arranged, exposed pipelines easy to break, causing more than half a day downtime per repair.
Break risk ↓ 90%
3
Bucket cylinder without protective cover, oil seal frequently scratched by gravel, needs replacement every month on average.
Oil seal life ×3
4
Unreasonable boom priority logic, repeated fine adjustments needed for leveling, increasing working time by 15% per shift.
Leveling efficiency +15%
5
Travel speed switching requires manual lever, frequent switching increases operation steps.
Operation steps -30%
6
Insufficient swing buffering, strong start-stop impact, dare not speed up in precise wall-following work.
Safer & faster
7
One-way stabilizer design, insufficient support during side digging, requires repeated repositioning.
Positioning times -50%
8
High diesel filler neck, manual bucket refueling without ladder leads to spilling and waste.
Zero fuel waste
9
Water drain of oil-water separator blocked by guard, needs tools for daily draining, often neglected causing injector damage.
Easy daily check
10
Air filter installed too deep, needs over 3 screws removed for inspection, artificially extended maintenance cycle.
Maintenance time -60%
11
Over 20 grease nipples on the machine, some inside chassis, taking over 20 minutes per shift.
Greasing time -70%
12
No quick battery disconnect, easy to discharge during long storage, extra charging delays rental.
Ready to rent anytime
13
Small bucket capacity, requires 2-3 more passes than competitors for same volume, hidden higher fuel consumption.
17. Fuel per m³ ↓
14
Wearing parts (pins, bushings) not universal, only OEM parts available, long lead time and high cost.
Wider parts availability
15
Compact radiator layout, easily blocked by dust, requires disassembly and over 1 hour for cleaning.
Clean in 2 minutes
16
No fault code on display, technician needed for minor faults, high rental downtime risk.
Quick diagnosis
17
Long pedal stroke causes foot soreness, reducing concentration during long work.
Comfort for long shifts
18
Limited seat adjustment range, uncomfortable for tall/short operators, affecting operation.
Fit all operators
19
No sun protection film, cab over 50°C in summer, operators suffer heatstroke.
Cool cab all day
20
Insufficient storage, no place for tools/water/phone, causing distraction.
More convenient storage
21
Small wiper coverage, large blind spots in rain, poor safety vision.
Full vision in rain
22
Dim working lights at night, narrow illumination, low efficiency & high risk.
Brighter & safer night work
23
Insufficient boom height, cannot reach 2nd floor/height work, needs extra equipment.
Higher reach capability
24
Low ground clearance, easy to bottom out on rocks/trenches, damaging chassis.
Better off-road performance
25
Thin sheet metal, easy to deform in minor collisions, rapid residual value decline.
Higher residual value
26
Insufficient boom height, cannot reach 2nd floor/height work, needs extra equipment.
Lower electrical failure
27
Poor cab sealing, dust & rain intrusion, fast dirt buildup & electric parts damage.
Dustproof & waterproof cab
28
Pins & bushings without optimized lubrication, early wear & noise, repair in 3 months.
Longer wear life
29
Hydraulic fittings without anti-loosening design, oil leakage after vibration, frequent tightening.
No leakage, no retightening
30
Unprotected glass, easy to crack by gravel, high replacement cost & rental downtime.
Longer wear life
31
No CE/EPA certification marks, cannot be registered in EU/US, banned from sale.
Full EU/US compliance
32
No English labels, high misoperation risk for foreign operators.
Global operator friendly
33
