KUL-1500

KUL-1500 winch control box

KUL-1500 is an aviation winch control box used in onboard lifting and cargo-handling systems. In the supplied context, the unit is associated with LPG-1500A Series 2 electric winch equipment and related systems such as LPG-150M. The block belongs to aviation technical property and is used for electrical control, switching and protection of winch operating circuits during loading, unloading and cargo movement operations on aircraft or helicopters.

Function of KUL-1500 in the lifting system

The main function of KUL-1500 is remote electrical control of the onboard winch. The box switches power and control circuits that operate cable payout and cable retraction. It also coordinates control commands from the operator’s control panel and supports operation of the winch drive under aircraft electrical system conditions. KUL-1500 is not the winch itself; it is the control and switching unit that allows the winch to operate safely and correctly as part of the cargo-handling system.

Operation with LPG-1500A and LPG-150M

KUL-1500 works with LPG-1500A electric winch equipment and may also be referenced in systems related to LPG-150M, depending on configuration. In a complete onboard cargo system, KUL-1500 is used together with the winch, hoist movement control equipment and operator control panels. According to the supplied context, related components include LPG-1500A, KUK-1 and PUT-1AM. The control box receives operator commands and routes them to the appropriate winch circuits for winding or unwinding the cable.

Interaction with KUK-1 and PUT-1AM

In the supplied system context, PUT-1AM is the operator control panel, while KUK-1 controls hoist / trolley movement. KUL-1500 controls the winch section of the system. During operation, the operator uses the panel to command cable movement, and the control boxes switch the relevant relays, motors and protection circuits. This layout separates operator input, hoist travel control and winch power control, making the complete lifting system easier to operate, inspect and maintain.

Protection and control logic

KUL-1500 participates in protection of electrical circuits and controlled winch operation. The supplied context mentions control of limit-switch signals, prevention of unsafe operation at travel limits and protection of lifting mechanism circuits from overload. The box may coordinate with end-position switches that stop cable payout or retraction when mechanical limits are reached. Exact protective logic, relay functions and wiring should be verified by the applicable LPG-1500A / LPG-150M technical documentation.

Identification and ordering of KUL-1500

Before ordering KUL-1500, the buyer should confirm the aircraft type, winch system configuration, required condition, connector version and documentation set. It is also important to clarify whether the request is for the KUL-1500 control box only or for a complete lifting system including LPG-1500A, KUK-1, PUT-1AM, cable equipment and spare parts kit. The unit may be required for winch control repair, restoration of cargo-handling equipment, replacement of a defective control box or spare parts stock.
