Bucket-elevator drives
Drives configured for bucket elevators — a bevel-helical or parallel reducer with an integral backstop to stop the loaded belt or chain running back when power is lost. Sizing accounts for the high starting torque of a full boot as well as running load. SES holds the range as an authorised STM Team distributor, covering base RXO / O bevel-helical or PT parallel; backstop Integral internal freewheel; output Solid or hollow shaft, shrink disc; input Close-coupled motor or free input. Executions include bevel-helical + backstop, parallel + backstop, hollow-shaft (shrink disc). It is specified most often into grain and feed elevators and cement and clinker elevators. Every part is genuine STM Team through official channels, with designation, specification and options confirmed against your duty before it ships — supplied from Kolkata and our branch network, with breakdown cover that does not sit in an inbox.

Where it runs.
You will find Bucket-elevator drives in the parts of a plant where this particular duty actually occurs. In practice that means grain and feed elevators, cement and clinker elevators, and equally aggregate and minerals, fertiliser handling. What links them is the duty rather than the machine name — base: Bevel-helical / parallel + backstop. If your installation is not on that list it matters less than you would think: the operating condition decides the specification. Send us the load, the speed, the running temperature and the environment it runs in, and we will match it to the right execution in the STM Team range and confirm what is in stock.
Specify it against the duty.
Specification here follows the operating condition, not the catalogue. Vertical elevator that must not run back — Reducer with integral backstop (anti-runback) Frequent start against a full boot — Size on starting, not just running, torque Shaft-mounted onto the head shaft — Hollow-shaft O with shrink disc + backstop Where two of those apply at once, specify for the harsher of the two — under-specifying is what puts the part back on the bench a month later. Send us the duty and we will confirm the execution.
Ordering this from SES.
The backstop is the safety item here — confirm rotation direction so it is fitted to hold, not lock, and size for the full-boot restart. Send the designation off the failed part and we will confirm the STM Team equivalent and stock position.
