This group brings together the cab electrical and sealing items needed around an XCMG XCT100/110 or XCA250BR repair: a power switch assembly with its lock set and keys, the related internal cable, and two oil-seal references. The parts are grouped together because a cab lock or switch failure rarely arrives alone — the same job often needs a seal, a keyed cylinder or a replacement wiring connector, and ordering them together keeps the references matched to the same machine.
The switch side is a keyed ignition and lock set rather than a bare electrical switch. It is supplied with keys, lock cylinders and attached wiring, so a worn key barrel or a damaged connector can be renewed as one assembly instead of rebuilt from loose parts. The seal side covers two separate oil-seal references; they are not a matched pair by default, so the correct one is chosen from the sealing point being repaired.
For buyers working from a workshop list, the Portuguese descriptions on the label and the English part numbers are both useful. The number is still the deciding reference. A photo of the old label, the connector face and the seal in its bore will usually settle a fitment question faster than a description alone. This is one small group within the wider XCMG spare parts range, and it can be combined with other cab, electrical or sealing items for the same machine.

The two oil seals in this group are small circular rubber seals, each bagged and labelled with its reference. They are the kind of part that is easy to overlook until a leak appears, and by then the seal lip is usually hardened, cut or contaminated. Replacing the seal is only half the repair; the sealing point, the shaft or bore and the venting around it need to be checked so the new seal is not damaged by the same condition that shortened the life of the old one.
Match the seal by the number on the old part or its bag, not by appearance. Two seals can look similar on the outside and still differ in lip profile, outer diameter or material. If the old seal has lost its markings, send a photo of it flat next to a ruler and a photo of the bore it came from; that is usually enough to narrow the reference. Do not prise a seal out with a sharp screwdriver and then fit the new one into a scored bore.
Before fitting, clean the bore and the shaft, remove any burrs or old sealant, and lubricate the seal lip with the system oil. Press the seal in squarely and evenly, without twisting the lip or driving it past its seat. On a cab or hydraulic repair, also confirm that the breather or return path is clear; pressure build-up will push a new seal out again. Store the spare seals in their bags, away from sunlight and sharp edges, until they are needed.
The two references are listed separately because they serve different sealing points. If both are weeping on the same machine, list both; if only one is wet, order the one that matches the removed seal. The seals sit in the crane hydraulic parts and cab sealing side of the range, not a universal assortment, so the number remains the safest way to order.
Why buyers choose Shenyang Winnings for XCMG crane parts
As a crane parts supplier based in Shenyang, close to the main XCMG supply base, we shorten the sourcing route for cab electrical and sealing items. The switch assembly, lock set, cable and seals are checked against the numbers on your old units, and we state whether an item is genuine XCMG/OEM supply or an alternative we have sourced.
Cross-checking and alternatives
That matters on crane electrical parts, where a connector or key profile can look right and still not fit. Every order is cross-referenced against the original XCMG drawing or data where one is available. Where a genuine part is out of production or unavailable, we say so and offer the alternative route rather than substituting silently. Structural and load-bearing items in the wider range are supplied in high-strength alloy steel and checked dimensionally against OEM data sheets; the cab and sealing items in this group are checked by number, connector type and seal profile.
Wider range
The same XCMG spare parts desk covers structure parts, crawler parts, maintenance parts and planetary parts, including track shoes, rollers, sprockets, controllers, monitors, sensors, filters, seal kits, wire rope, cab controls, clutches and brakes.
Within that range, crane hydraulic parts cover pumps, motors, valves and cylinders, while electrical and safety items cover switches, lock sets and sensors. The wider model coverage includes crawler cranes QUY50, QUY80, XGC100, XGC150, XGC260, XGC400 and XGC650; truck and all-terrain cranes QY25K, QY50K, QY70K, XCA100 and XCA220; and rotary drilling rigs XR150D, XR220D, XR280 and XR360. Boom and attachment parts can be customized for various XCMG crane and rotary drilling rig models; for the cab items here, the listed references are the starting point.
One supplier for a mixed repair list
A repair list often mixes brands. We can source XCMG, SANY, ZOOMLION and FUWA items and prepare them under one reference check, so the buyer deals with one technical contact and one set of documents. If a Portuguese description, an old number and a current number all appear on the same list, the desk traces them back to the machine and confirms which reference is current.
Who handles your questions
Selection and installation questions go to the same XCMG crane parts desk in Shenyang that quotes the order, not to a separate call centre. The engineers there each have more than ten years in construction machinery, and they answer from the machine model, the number on the old unit and photos of the connector face, key profile or seal bore. English is the working language; a Brazilian buyer can send local wording such as POLAINA LD or CABO INTERNO DA PATOLA next to the number and it will be matched to the reference.
Before you pay
The risky moment on a cab switch is fitment, not the price. Send the plate details, the old reference and a flat photo of the part, and the desk will say whether 860504192 or 860548748 is the one your cab carries, whether the auxiliary cylinders in the set match your door locks, and which of the two seals belongs at the point that is leaking. If the photo and the number disagree, you hear about it before the item ships rather than after it lands.
During installation
On the switch side, the engineers can walk your technician through the order of work: isolate the battery, release the connector before the housing is disturbed, keep the key in the cylinder while the housing is aligned, and seat the plug fully before the unit is bolted down. On the seal side, what decides whether the repair holds is a clean bore, an undamaged shaft, a lubricated lip and an even press without twisting. These seals sit in the crane hydraulic parts side of the range, where the cause of the first leak — a blocked breather, a scored shaft — has to be cleared before a new seal goes in.
Tracing a fault across time zones
Messages from Brazil, Vietnam, Thailand, India, Saudi Arabia, the UAE and Panama usually arrive outside Shenyang office hours; they are picked up at the start of the next working session with the model, symptom and photos already attached. A short video is often the fastest evidence: a key that turns without cranking, a dashboard that drops out over rough ground, a seal that weeps only when the machine is warm. Where a fault crosses from crane electrical parts into the sealing side, the same desk holds both, so you are not carrying a diagnosis between two suppliers.
After dispatch
If an item arrives and does not match what came off the machine, send the number, a photo of the part as received and the condition of the packing; the case is reviewed against the reference that was confirmed in writing before dispatch and answered the same way. Each machine's references are kept on file, so the next order for the same crane starts from the last confirmed number instead of the plate again.
Not sure which part fits your machine? Send the part number, the machine model, and a photo of the nameplate or the worn item, and our engineers — each with more than ten years in the construction machinery business — will confirm the correct reference and quote it. We advise on installation, help trace faults, and answer technical questions before and after dispatch. Since 2017 we have built this support on a supplier network covering FUWA, SANY, XCMG and ZOOMLION, so older and hard-to-find references can usually still be sourced.
They are listed for XCMG XCT100/110/XCA 250BR. The wider XCMG spare parts range also covers crawler cranes, truck and all-terrain cranes, and rotary drilling rigs, but for this group start with the machine plate and the number on the old switch, cable or seal.
We supply XCMG crane parts across four main groups: hydraulic pumps, valves and cylinders; undercarriage components; electrical and safety systems such as sensors, controllers, switches and lock sets; and boom and attachment parts. This cab switch and oil-seal group sits in the electrical and sealing side of that range.
Yes. Our technical team supports overseas buyers with part selection, installation and commissioning, and answers questions before and after dispatch. Send the model, the old part number and clear photos of the connector or seal so the answer is specific to your machine.
Yes. Boom and attachment parts can be customized for various XCMG crane and rotary drilling rig models. Send the machine model, serial and drawings or photos of the section you need; the team will confirm what can be produced and what should be supplied as a standard part.
Start with the number on the old switch and the connector face. The three switch assembly references in this group share the same description but may differ by key profile, lock cylinder set or wiring plug. A photo of the old label and the plug, plus the machine model, lets the parts desk confirm the match before you order. For crane electrical parts, also check that the old switch failed on its own and not because of a blown fuse or damaged earth.
No — they are two separate oil-seal references for different sealing points. Check the seal you removed and order the reference that matches it; if both are weeping, list both. These seals belong to the crane hydraulic parts and cab sealing side of the range, so the number on the old bag is the safest guide.
Send the Portuguese description with the number and a photo. Names such as POLAINA LD and CABO INTERNO DA PATOLA are local catalogue wording; the number confirms the item. If the label shows a bracketed number, include that too, as it may be the alternate reference for the same part.
Isolate the battery before work starts, check the connector and earth points, and make sure the key cylinder turns freely before the switch is bolted in. For the seals, clean the bore and shaft, lubricate the lip, and press the seal in squarely. If the old seal was pushed out by pressure, find the cause before fitting the new one.
