The factory

Lianjie (Beijing) Technology Development Co., Ltd.

A cleaning-equipment manufacturer in Daxing District, Beijing, working since 2016. We build, assemble and test industrial scrubbers, sweepers, vacuums and pressure washers, and we supply selected imported lines for customers who standardise on them.

What we actually do

Manufacture, assemble, test, document

Our production is organised around configured orders rather than a fixed catalogue of stock machines. A customer who needs a 550 mm deck instead of 530 mm, a 60 Hz motor, a different brush hardness or a branded body gets that specification confirmed in writing and built into the machine.

That flexibility is why we can serve both a single-unit OEM order and a fleet replacement programme. It also means we do not publish claims we cannot document: where a certificate, test report or declaration is needed for your market, we tell you what we can supply and what we cannot.

Good to know
  • Working languages: English and Chinese, written quotations in English.
  • Export packing and documentation prepared for sea freight.
  • Spare parts and consumables quoted alongside the machine, not after the sale.
  • Electrical configuration matched to the destination market on request.
  • Selected imported lines supplied alongside our own models where a site standard requires them.
Order process

From requirement to packed machine

01

Requirement

Floor area, soil or debris type, power supply, working hours and destination port. We confirm the machine configuration in writing before anything is built.

02

Build

Assembly and electrical work in our Beijing workshop, with the pump, battery and control set matched to the configuration in the confirmed specification.

03

Test

Run-in and function check on every unit: brush and squeegee operation, vacuum performance, pressure and flow at the nozzle for washers and jetters.

04

Pack and document

Export packing with moisture barrier, packing list, operator manual and wiring diagram. Spare-parts kits are packed with the shipment when ordered.

Where we are

Visit the workshop

Qingcai Road, Qingyundian Town, Daxing District
Beijing, China

Buyers who order fleets usually want to see the assembly line, the test bay and the packing process before releasing a purchase order. We host visits at the workshop and run video walk-throughs for customers who cannot travel.

Tell us the models you are considering and we will set up the machines for the call, so you see the configuration you would actually receive rather than a demonstration unit.

Brands on the floor

Own DIHAI models, plus the lines plants already standardise on

Most of the catalogue is built in our own workshop. For buyers who run a mixed fleet, we also supply selected imported lines so a single order covers every machine on site — with one technical contact and one spare-parts list.
