An automatic sliding door arrives on site as a set, not as a single machine. The operator, the track, the rollers, the sensors and the small fixing parts are packed together, and the configuration is settled at the quotation stage rather than during installation. This guide sets out a verification sequence for a JL-2200 automatic sliding door set: what the carton should contain, how the single and double leaf versions differ, how the track is supplied, which parts are optional, and what the purchase order needs to state. The motor matters, but it is one line in a longer specification.
An automatic sliding door set breaks down into four groups.
Drive. The motor, the control module, the trolley pulley and the timing belt. The motor turns the pulley, the belt runs the length of the track, and the control module holds the settings for opening speed, closing speed and hold-open time.
Carriage. Hanging rollers, connection brackets, door stoppers and floor guides. The rollers carry the leaf on the track, the brackets join the leaf to the rollers, the stoppers end the travel at each side, and the floor guide keeps the bottom edge of the leaf in line.
Detection and operation. Microwave sensors and remote controls. The sensors trigger the opening; the remote controls give hand-held operation of the door.
Installation consumables. Electric wires and screws.
That is twelve items. When a set is unpacked, the packing list should be checked against all four groups before installation begins, because a missing bracket or a short set of rollers stops the work as effectively as a missing motor.
The single-leaf configuration is rated 120 kg. The double-leaf configuration is rated 250 kg. Both use the same automatic sliding door set; the difference is the number of components that ship with it, which rises with the number of leaves.
An order that says "one automatic sliding door set" leaves the decisive line open. State single or double leaf at the quotation stage, then weigh the finished leaf — glass, frame and fitted hardware together — and check that figure against the rating. A leaf that has been weighed is a specification; a leaf that has been estimated is a guess.
The automatic sliding door track is supplied as 2.1 m aluminum rails. A single-leaf set ships with one rail. A double-leaf set ships with two, joined to give 4.2 m of travel. Unless a project asks for something else, this standard arrangement is what leaves the factory.
That convention is worth knowing for two reasons. First, the rail count should match the leaf count on the order: one rail per leaf, two for a pair. A double-leaf automatic sliding door set that arrives with a single rail cannot be installed. Second, the rails can be cut. If the opening is narrower than the standard length, the rail is cut on site to suit; if a project needs more than 4.2 m, the track can be extended to 6 m on request. What the buyer needs to confirm is the leaf configuration, not a made-to-measure length calculated in advance.
Microwave sensing is part of the standard automatic sliding door set. A safety beam at the closing edge, a fingerprint reader for access control and a wireless switch are optional, and further add-ons can be quoted on request.
Optional devices are better written into the original order than added afterwards. An add-on ordered later arrives as a separate shipment and needs a second visit to the site, while the door is already in service. List every device the entrance needs on the quotation, even where the answer is "none for now".
The automatic sliding door set takes 8–12 mm glass. Two details belong in the first enquiry rather than the final drawing: the glass thickness, and whether the door is framed or frameless. The two door types are quoted with different fixing parts, so a quotation built on the wrong assumption has to be revised before it can be ordered.
An automatic sliding door set ships in two cartons. Everything except the track goes in the first carton; the track is packed separately in its own carton. On a double-leaf order that means one carton of components and one carton of two 2.1 m rails. Both cartons should be counted against the packing list on arrival, and the track carton needs storage space of at least its own length.
Shipment can be arranged as LCL or as a full container. The minimum order is one set. Sets in small quantities, under ten, are usually available from stock and ship in 5–7 days; larger orders run 20–30 days. Production time should be confirmed against the actual quantity on the order, since the two ranges are a guide rather than a fixed schedule.
OEM and ODM work is available with a customer logo printed on the motor and on the packaging, at a minimum of 100 sets. The warranty on the automatic sliding door set is 3 years.
Six lines carry the configuration of an automatic sliding door order:
Model: JL-2200.
Leaf configuration: single or double.
Track: one 2.1 m rail, or two.
Optional devices: safety beam, fingerprint reader, wireless switch.
Glass door: framed or frameless, and glass thickness.
Logo: required or not.
Many ordering problems with an automatic sliding door are configuration problems rather than product faults. A set built for one leaf will not serve a two-leaf opening, and the error only becomes visible when the cartons are open and the installation crew is on site.
The full range is listed on the Jianlai automatic sliding door product page. For a specific entrance, confirm the model's data sheet against the measured opening before the order is placed.
