Case study
Challenge, solution, delivery, and result
Overview
The Pakistan Zhongtong bus production line is a contract-level reference for CKD bus manufacturing in Karachi. The public capacity record is 3,000 units per year, with 13 stations and a 5JPH line rhythm.
Challenge
The Karachi CKD bus project needed more than final assembly stations. The line had to connect body stretching, skeleton assembly, welding transfer, axle lifting, engine lifting, and launch-ready production flow.
Solution
DUOYUAN connected side panel hot stretching, skeleton assembly, roof panel stretching, welding trolley movement, axle lifting, engine lifting, and line-side custom equipment into one bus CKD package.
Delivery
DUOYUAN organized the Zhongtong scope as a 13-station, 5JPH CKD bus production line with a 3,000-unit annual capacity target.
Result
The contract record supports three citable facts: the line was configured for Karachi CKD bus production, the equipment scope included 13 stations at 5JPH, and the annual capacity target was 3,000 units per year.
Project review notes
What this case shows for a similar factory plan
Use the case to compare scope, not only as a project name.
Use Pakistan Zhongtong Bus Production Line to compare vehicle type, line scope, equipment boundary, and launch result before deciding whether the RFQ is for a complete line, one process section, or a retrofit package.
Start with Assembly Fixture and Jig Package, then use the related reading below to prepare vehicle data, layout constraints, capacity targets, and commissioning expectations.

Common project questions
Common Questions
What project facts are published for Pakistan Zhongtong Bus Production Line?
Pakistan Zhongtong Bus Production Line is published as a Pakistan reference for Bus CKD production. The visible scope is Pakistan Zhongtong bus production line for CKD bus manufacturing in Karachi, including side panel hot stretching, skeleton assembly, roof panel stretching, welding trolley, axle lifting, and engine lifting. The reported result is The Karachi CKD bus project covered side panel hot stretching, skeleton assembly, roof panel stretching, welding trolley, axle lifting, and engine lifting.
How should buyers use this case in an RFQ discussion?
Use this case to compare the line boundary, vehicle program, equipment families, and acceptance target before asking for a similar solution. A buyer should still provide workshop layout, capacity, SOP timing, and local installation conditions.
Which equipment families are most relevant to this project reference?
The page connects this reference with Assembly Fixture and Jig Package, Bus and Coach Production Line, Custom Non-Standard Equipment. DUOYUAN can review whether the RFQ needs a complete line package, a single process section, or a retrofit around these equipment families.
What solution scope is shown in this project reference?
DUOYUAN supported side-panel hot stretching, frame assembly, roof-panel stretching, welding process trolleys, axle lifting, engine lifting, and related lifting equipment. Use this case to compare the equipment boundary, process section, and commissioning responsibilities before planning a similar RFQ.
What result should buyers pay attention to when comparing this case?
The project established a defined bus welding-line equipment scope for Zhongtong's Pakistan CKD bus production program. Buyers should compare this result with their own workshop layout, takt target, utility conditions, local installation resources, and acceptance standard.
What information should be prepared for a similar project?
Prepare the vehicle program, body or chassis data, target output, takt expectation, current workshop layout, utilities, local installation plan, SOP schedule, and the work scope expected from the equipment supplier.
