Introduction
This document provides technical specifications and operational guidelines for the Nakashima TCT model side thruster, a controllable pitch propeller system used in marine vessels. It includes details on the components, operation, features, and maintenance of the thruster system.

Specifications
The TCT model consists of a thruster body, hydraulic pump unit for pitch change, remote control system, and prime mover. The system is designed to provide greater thrust, easy installation, low vibration, and noise, and simplified maintenance.

Operation and Control
Control is achieved via a dial on the wheelhouse control panel or a portable controller. The hydraulic pump unit's solenoid valve is activated, sending pressure oil to the thruster hub's cylinder, which adjusts the propeller's pitch angle. The pitch angle is displayed on the control panel.

Features
1. Greater Thrust: Redesigned blades and strengthened body provide increased thrust.
2. Easy Installation: Compact design allows installation further forward in the hull.
3. Minimum Vibration - Low Noise: Unique forward-skew design reduces noise and vibration.
4. Easy Maintenance and Inspection: Propeller blades can be replaced easily, and the thruster unit can be removed for onshore inspections.

Optional Equipment
Customers can opt for additional equipment such as Overload Protection (OLP), Automatic Load Control (ALC), Powertron Starter, and Joystick Control System.

Oils
The system requires clean, approved oils, typically ISO VG68 gear oil or equivalent.

Scope of Supply
The supply includes the thruster body, shaft coupling, header tank, control system, hydraulic pump unit, remote control, and standard spares and tools.

Planning Specification
The document provides detailed specifications for various models, including dimensions, motor output, thrust, and weight.

Remarks
Model TC differs slightly in structure and hydraulic system from Model TCT. Specifications may change without notice.
