Quick Answer
An e-rickshaw loader chassis is a welded steel frame that carries the driver cabin, battery pack, drivetrain and cargo bed of an electric 3-wheeler cargo vehicle. KM Engineering manufactures jig-welded loader chassis in Faridabad from MS tubes and channels (ERW IS 1161 + hot-rolled IS 2062), payload-rated for 500–800 kg, with CED primer plus powder-coat finish — typical MOQ 25 units and 20-day lead time.
What Is E-Rickshaw Loader Chassis Manufacturer?
An e-rickshaw loader chassis is the structural backbone of a cargo-segment electric 3-wheeler. It carries the driver seat, battery housing, motor mount, rear axle/differential, and the cargo bed frame — while absorbing road loads and supporting the full gross vehicle weight (GVW) during 500–800 kg cargo operations common in last-mile logistics, agricultural transport, and small-business intra-city delivery.
KM Engineering fabricates loader chassis for 15+ Indian EV 3W OEMs serving the e-loader segment. Our chassis use IS 2062 E250 hot-rolled channel for the main rails and IS 1161 ERW tube (medium duty, 2.9–3.6 mm wall) for cross-members, A-frame, suspension brackets and cargo-bed support. All welding is done on dedicated jigs to preserve frame geometry within ± 3 mm over the full wheelbase.
Chassis finishing is a two-stage process: CED (Cathodic Electro-Deposition) primer for deep corrosion protection on interior tube surfaces, followed by powder coating for cosmetic and UV-resistant exterior. Our Faridabad facility supports production volumes from pilot runs of 25 units to steady-state orders of 500+ units per month, with full material traceability and jig-based FAI documentation.

Manufacturing Process
How KM Engineering fabricates E-Rickshaw Loader Chassis Manufacturer — step-by-step process from drawing review to dispatch.
Drawing Review & Jig Setup
OEM-supplied 2D drawings and 3D models are DFM-reviewed for weld access, jig clamp points, and fixturing feasibility. A dedicated chassis jig is built or reconfigured — typical jig setup time 5–7 working days for a new chassis model.
Material Qualification
Channel, tube and plate stock inspected against supplier TC. Batch-ID traceability maintained from raw material through final QC.
Cutting & Profile Preparation
Main rails cut by bandsaw to length; tube members cut on tube-laser (where volume justifies) or bandsaw with fishmouth preparation for round tubes. Deburred before assembly.
Bending & Forming
Frame rails bent on CNC press brake or bottle-bender; round tubes bent on NC tube bender where curved members are required.
Jig-Welding
Parts clamped in chassis jig; tacked first to verify geometry; then MIG-welded with controlled sequence to minimize distortion. Inter-pass cooling enforced on critical joints.
Geometry Inspection
Chassis released from jig; diagonal measurement (FL-RR vs FR-RL) within ± 3 mm; wheelbase within ± 2 mm; camber/toe reference points laser-verified.
Grinding & Surface Prep
Weld beads ground where cosmetic or clearance-critical; 7-tank pre-treatment for CED line.
CED Coating
Cathodic Electro-Deposition primer applied by dip. Deep throwing power reaches interior tube surfaces — critical for corrosion protection in Indian monsoon conditions.
Powder Coating
Top-coat powder application and cure at 180 °C, 20 minutes. Standard color matte black RAL 9005 or OEM-specified.
Final QC & Packaging
FAI on first chassis of each batch (full dimensional report); 100% diagonal + wheelbase check on production. Individual pallet-mounted with edge-protection for road transport.

Frequently Asked Questions
What payload ratings do you manufacture?
Three standard design variants: 500 kg, 650 kg and 800 kg payload. Each variant has different main-rail section, cross-member thickness, and suspension bracket sizing. Non-standard payloads between 400–1000 kg can be engineered on request.
Is the chassis jig-welded or table-welded?
All our chassis are jig-welded. A dedicated clamp-fixture jig holds every chassis in the same geometric reference during tacking and full welding. This delivers repeatability of ± 3 mm over the full wheelbase — which is why OEM assembly lines run smoothly. Table-welded chassis (no jig) routinely drift ± 8–12 mm and cause issues at OEM line assembly.
Do you include CED primer as standard?
Yes. CED (Cathodic Electro-Deposition) primer is standard on our loader chassis because it provides deep corrosion protection inside hollow tube sections — critical for Indian monsoon service life. The CED coat is then topped with epoxy-polyester powder for UV and cosmetic finish.
Can you supply chassis with the OEM's own battery cradle or housing mount?
Absolutely. Share the battery box drawing and preferred mounting-pattern, and we integrate the cradle rails or housing mount during the jig-build stage. Most of our OEM customers use this workflow — one partner (us) for the frame, another for the pack, assembled at the OEM.
What's the typical lead time for the first prototype chassis?
20 working days from approved drawings. This includes 5–7 days for jig build/reconfiguration, cutting and welding time, surface prep, CED, powder coat and final QC. Subsequent production runs (after jig is established) ship in 10–14 days per batch of 50.
Do you handle suspension and steering attachment brackets?
Yes. We weld in OEM-specified leaf-spring shackles, shock mounts, steering-column brackets and king-pin pickups — all as part of the standard chassis scope. Suspension components (leaves, shocks, tie-rods) are supplied by the OEM or sourced through customer-specified vendors.
What production capacity can you scale to?
Current facility supports up to 500 chassis per month per active model line. For customers planning higher volumes, we can run parallel jigs or reserve additional bay capacity. Discuss volume planning at the DFM stage so jig and resource capacity is secured.
Do you provide type-approval or certification?
Type-approval for the completed vehicle is issued by ARAI or ICAT to the OEM (you) — because it covers the full vehicle (chassis + drivetrain + body + cells). We support your certification workflow by providing chassis engineering documentation, material TCs, weld-procedure specifications, and FAI dimensional reports as requested by the lab.
Are there volume discounts?
Yes. Pricing tiers at 25 (prototype), 100, 250, 500 and 1000+ units per order. For annual rate-contract (RC) arrangements, we offer additional pricing benefits against committed monthly offtake.
