XILIN QDD20E / QDD30E electric tow tractors

What the official reference establishes

The official product heading groups QDD20E and QDD30E under one tow-tractor page. Its source photograph shows a seated electric tractor without forks, and the table gives separate model columns. The listed rated towing masses are 2000 kg and 3000 kg respectively, both marked with a 60-minute basis. These figures describe towing, not a load carried on forks, and they do not establish the permissible train for a particular route, trailer or slope.

Keep the reference and interfaces together

The same table lists rated tractive force as 500/50 and 750/75 under a combined N/kg unit heading. Preserve that source notation and have the supplier confirm the force units and test basis; do not silently turn it into a new rating. Both columns show 1720 mm overall length, 968 mm width, 1500 mm outer turning radius and 36 V. Confirm the actual hitch height, trailer connection, battery and charger in the quotation instead of inferring them from the model suffix or photograph.

Keep the supply package explicit

The prose advertises an all-AC electrical arrangement and an electromagnetic parking brake. The technical image instead lists transistor speed control and mechanical/hydraulic braking. These may refer to different versions or systems; the page does not resolve the difference. This reference records the discrepancy and does not declare a current motor, controller or complete braking specification. Ask for a dated model-specific datasheet, intended duty, towing restrictions and the exact configuration offered. Maintenance-free and roll-away prevention language is not adopted as a guarantee.

Questions for the proposed product

What belongs in the requirement?

Give the full proposed model and revision, load dimensions and mass, operating route, quantity and destination. Describe the task and site constraints before comparing quotations. A catalogue image does not establish the equipment configuration or suitability.

Which current documents are needed?

Request a configuration-specific datasheet, applicable operating manual, load or towing limits and matched battery/charger information. Have the responsible supplier assess the actual workplace and duty. Keep discrepancies between web text and tables open until documented.

What should the written offer identify?

Confirm the quoting company, exact machine, condition and origin, included battery, charger and accessories, delivery terms, warranty and acceptance documents. Existing contact and purchasing links are preparation routes; clicking them is not a completed or qualified enquiry.

From product research to a comparable request

Prepare a written requirement with the duty or installed component identity, current drawings or part records, quantity, destination and requested supply scope. Compare the exact proposed configuration or component and keep unresolved differences visible. Existing supplier and purchasing tools remain below; following a link does not itself send an enquiry.

Sources and evidence boundary

The official About and Contact pages identify Ningbo Ruyi and the XILIN brand at No. 656 Taoyuan North Road, Ninghai, Ningbo. Four detail bodies, photographs and technical images were read. Separate model columns and measurement labels are retained. QDD electrical/braking descriptions differ between prose and table; CSD20 nominal and elevated-capacity entries do not agree. Current documents must resolve those limits before selection. Company awards, patents, market share, maintenance claims, certification and workplace suitability are not independently audited. Illustrations explain visible family form, not stock or an approved configuration.
