Judging whether a Deep Digging Excavator is "easy to use" never depends solely on parameters — but on details hidden in daily operations such as sun visors under the scorching sun, pedals on rainy days, and attachments replaced in 15 minutes. The 5 designs of Hengwang Deep Digging Excavator (HWL75S, HWL90, HWL150, etc.) are helping operators save time and reduce fatigue through details.
1.15-minute quick attachment replacement: Wait 45 minutes less, work 1 hour more
Traditional wheeled excavators need to remove 3 sets of bolts to replace attachments, taking at least 1 hour. Hengwang Deep Digging Excavator (such as HWL40, HWL80) are standard with "snap-type quick-change interfaces". Unlock the snap → take the old attachment → clamp the new attachment, 3 steps completed in 15 minutes, saving 45 minutes compared to traditional models. A French construction team tested with HWL150: changing attachments twice a day (from bucket to breaker), digging 30 more cubic meters of soil.
2.1650mm tail swing radius: Reverse 3 fewer times in narrow roads
Construction passages in old European urban areas are often as narrow as 2.5 meters. The minimum tail swing radius of HWL75S Deep Digging Excavator is only 1650mm, 30% smaller than similar models, allowing a single U-turn in narrow roads without repeated reversing. In Dutch pipeline projects, this design saved 2 minutes per trip, earning 2.7 more hours in 80 trips a day.
3.Hydraulic double outriggers with automatic leveling: Slope leveling completed in 10 seconds
When operating on a 35° slope, traditional wheeled excavators need to adjust outriggers repeatedly. The hydraulic double outriggers of HWL90 Deep Digging Excavator have automatic leveling, making the body level within 10 seconds (error ≤1°), saving 10 minutes per time compared to manual leveling. A Swedish operator said: "I used to try 5 times to level it, now it's done in one go, digging 20 more cubic meters every day."
4.Anti-slip widened pedals: No slipping when getting on/off in rainy days
Wet pedals on rainy construction sites are a hidden danger. The pedals of Hengwang Deep Digging Excavator have diamond-shaped anti-slip patterns (2mm deep), widened by 8cm, and tilted 15° for drainage, with accumulated water drained in 10 seconds. 83% of operators reported: efficiency of getting on/off increased by 10%, no more slipping.
5.Rotatable sun visor: Sweat 2 hours less under the scorching sun
At noon in summer, sunlight directly shines into the cab. The sun visor of HWL215 Deep Digging Excavator can rotate 360°, accurately blocking light without blocking the view. German operator Mark said: "No need to squint at the screen, ditch digging precision is higher, and fatigue is reduced by 30% after 4 hours of operation."
These details are hidden in HWL75S's concept of "more thoughtful design" and in the practical optimizations of HWL150 and HWL215. The efficiency gap of Deep Digging Excavator is often hidden in these "easy-to-use" details.
