1.8 Ton Mini Excavator: QS-18 Price and Applications
News · Updated October 16, 2026
Quick Answer
A 1.8 ton mini excavator can be considered for drainage, landscaping excavation and farm maintenance when its actual dimensions and working range match the site. For the Qisheng QS-18, the October 9, 2026 catalogue lists a width of 1,160 mm and maximum digging depth of 2,100 mm for the stated configurations.
Use those figures to assess the job before requesting a price. “1.8 ton” identifies the model class; it is not a verified operating or shipping weight for every engine, cab and attachment combination.

Different listed engine power does not, by itself, establish which configuration will excavate faster or lift more. Hydraulic configuration, working conditions and the approved attachment also matter. Compare the complete machine, service requirements and documentation rather than ranking the options using one number.
Assess the Job in Two Stages
First establish whether the machine can reach the work. Then consider the supplied tool and operating arrangement.
For an illustrative excavation requiring 1,800 mm depth below the machine's working level, the QS-18's listed 2,100 mm maximum passes an initial depth screen. That 300 mm difference is not a guarantee of usable clearance or production: reach at the required location, ground conditions and working space still need assessment.
If the required depth is 2,300 mm, it exceeds the QS-18 catalogue maximum. The QS-25 lists 2,600 mm and may be a candidate for further assessment. These are stated examples, not customer project results.
Access can rule out a machine even when its depth is adequate. A straight 1,100 mm opening is narrower than the QS-18's listed 1,160 mm overall width. Do not assume that optional retractable tracks solve the problem without the actual retracted width and blade arrangement.
Match the Attachment to the Application
| Application | Information to provide | Configuration question |
|---|---|---|
| Drainage excavation | Required depth, trench width and access | Which compatible bucket suits the excavation? |
| Landscaping | Excavation dimensions, soil and intended finish | Are separate digging and finishing tools useful? |
| Fence or planting preparation | Required hole dimensions and material | Is the proposed auger suitable for the mounting and hydraulics? |
| Farm maintenance | Recurring tasks and transport between work areas | Which tools and transport arrangement cover the actual work? |
The catalogue lists pilot controls and boom swing as standard, with retractable tracks, a cab and compatible attachments available to specify. Confirm the supplied combination. A pictured breaker or auger does not establish that it is included or that every version has the same hydraulic requirements.
Use the farm-use page or landscaping page to organise your application requirements.
What Changes the QS-18 Price?
Identify the engine, operator station, track arrangement, coupler and attachment list before comparing prices. Add the destination and quantity so the delivery arrangement can be quoted on the same basis.
For U.S. dealer orders, ask for a tax-inclusive DDP total to the delivery address. European buyers can ask about LCL shipping to a convenient port and eligible ocean-freight-waived routes. Warehouse supply for individual buyers depends on the model available and the collection or delivery arrangement.
The quotation comparison guide explains the delivery and equipment items to compare. The QS-18 product page remains the main page for the model specification and enquiry.
Frequently Asked Questions
Does 1.8 ton mean that the supplied machine weighs exactly 1,800 kg?
No. It is the model-class description used here. Request the actual operating and transport weights for the selected configuration before making payload or freight decisions.
Is the QS-18 always better than a smaller machine?
No. A machine that cannot enter the site is unsuitable regardless of its digging depth. Compare access, depth, attachments and the real task instead of choosing by class alone.
Can I order one QS-18?
Yes. Qisheng's minimum order is one machine. Send the required engine, attachments, destination and quantity to receive a configuration-specific offer.
Request an Application Check
Provide the narrowest access width, required depth, main material and attachment needs. Ask Qisheng Machinery to check the proposed QS-18 configuration before choosing the machine solely from its tonne class.
