PUT-1AM

Function of PUT-1AM in the LPG-150M system

The main function of PUT-1AM is manual remote control of hoist and winch operating commands. The operator uses the panel switches to send control signals to the connected control boxes, which then switch power to the corresponding electric drives. The panel supports movement of the hoist trolley along the cabin guide rail and operation of the winch drum for raising or lowering loads. This makes PUT-1AM an operator interface for the onboard cargo-handling system rather than a standalone lifting device.

System composition and related units

PUT-1AM works as part of the LPG-150M system. The supplied context identifies LPG-1500A as the electric winch, KUL-1500 as the winch control box, KUK-1 as the hoist movement control box and PUT-1AM as the hoist control panel. The system also includes the cable arrangement and spare parts kit. In operation, PUT-1AM is electrically connected with KUK-1 and related control circuits, while winch operation is coordinated with LPG-150M / LPG-1500A equipment and its drive motors.

Installation in Mi-8 / Mi-17 cargo cabin

According to the supplied context, PUT-1AM is installed in the cargo cabin of Mi-8 / Mi-17 family helicopters. It is usually located near the left entrance door, cargo hatch or onboard boom / hoist operating area. The panel may be fixed in a wall holder or bracket on the internal fuselage frame. During cargo-handling work, the operator may use it as a removable wired control panel, depending on aircraft installation. The unit is connected to the aircraft electrical system through a shielded flexible cable and aviation plug connector.

Control logic and protection

PUT-1AM operates by switching 27 V DC control circuits. When the operator selects “forward” or “back,” the signal goes to the KUK-1 control box, which activates the hoist trolley drive for longitudinal movement along the cabin monorail. When “payout” or “retraction” is selected, the winch drum drive operates to lower or raise the cable. The supplied context also describes protective logic that prevents conflicting commands and uses limit switches to disconnect power at end positions or at the cable travel limits.

Identification and ordering of PUT-1AM

Before ordering PUT-1AM, the buyer should confirm the aircraft type, LPG-150M system configuration, required condition, cable / connector version and documentation set. It is also important to confirm whether the request is for the PUT-1AM panel only or for related LPG-150M components such as KUL-1500, KUK-1, LPG-1500A or the cable system. The panel may be required for hoist control repair, cargo cabin equipment restoration, replacement of a damaged operator panel or spare parts stock.
