Wireless Remote Control Operation Manual for
30 Ton & 50 Ton RTG Crane - Mexico Project

Introduction

Operating a Rubber Tyred Gantry (RTG) crane with a wireless remote controller can be smooth and safe if you know the right steps. This guide is designed for the 30-ton and 50-ton RTG cranes we supplied for a project in Mexico. These cranes have been customized to suit the working environment and loading requirements of the site, so the procedures here match exactly how this equipment works.

The aim is simple: give operators clear, step-by-step instructions they can follow every day without second guessing. Whether you are new to RTG cranes or have years of experience, having a written reference helps reduce mistakes, prevent downtime, and keep everyone safe on site.

Purpose of This Guide

The goal here is not just to explain which button does what. It's to make sure you understand:

• How to start and stop the crane safely.
• When and how to use the tyre steering modes.
• The meaning of the angles (0°, 45°, 90°) and what each is for.
• Best practices to avoid damage or unnecessary wear.

This is not theory — it's based on how the actual Mexico project cranes are built and programmed.

RTG Crane Model

• 30 ton RTG Crane – suited for container handling, yard transfer, and light bulk material.
• 50 ton RTG Crane – used for heavier loads, larger containers, or where more lifting power is needed.

Control System

Each crane is fitted with an industrial wireless remote controller that can handle:

• Hoisting and lowering
• Trolley movement (left/right)
• Gantry travel
• Tyre steering rotation
• Emergency stop

The remote uses photoelectric limit switches to stop tyre rotation exactly at set positions. This means no over-rotating or guessing when to stop — the crane takes care of that automatically once you hold the right button.

Special Note: Tyre Steering

This crane's tyre steering mechanism is only for no-load condition. That's not just a manufacturer's suggestion — it's a hard rule to protect the tyres, steering motors, and limit switches. Turning the tyres with a container in the spreader puts too much stress on the system. Always:

• Unload before changing tyre direction.
• Check that the tyres are free of obstructions before rotation.
• Use the correct button combination for the target angle.

RTG Crane Start-Up and Shutdown

Knowing how to safely start and stop the crane is key to smooth operations. Here's a simple guide to get you going and to shut down properly.

Start-Up Procedure

• Turn the green power knob to ON.
• Turn the red emergency stop button clockwise to reset it.
• Press the green START button twice to power up the crane.

Shutdown Procedure

Normal Stop:

• Press the red emergency stop button once.
• Turn the green power knob to OFF.

Emergency Stop:

• If there's a sudden problem, press the red emergency stop button immediately.

Hoisting Mechanism Operation

Controlling the hoist smoothly is crucial for safe lifting and lowering of loads. Here's how to handle it with the remote:

Lift Load (Up)

• Press and hold the ↑ (Up Arrow) button on the remote.
• The hoist will raise the load steadily as long as you hold the button.

Lower Load (Down)

• Press and hold the ↓ (Down Arrow) button on the remote.
• The hoist will gently lower the load while the button is pressed.

Important Note

• Always make sure the hook is directly above the load's center before you start lifting.
• This prevents the load from swinging or slipping, which keeps everyone safe and protects the equipment.

Smooth and careful control will keep your lifts steady and avoid unnecessary strain on the crane.

Trolley Mechanism Operation

Moving the trolley smoothly helps position the load exactly where you need it. Here's the basic remote control guide:

• Move Left： Press and hold the ← (Left Arrow) button on the remote to move the trolley left.
• Move Right：Press and hold the → (Right Arrow) button on the remote to move the trolley right.
• Important Note ：Avoid overloading when moving the trolley to prevent mechanical strain or accidents.

Emergency Operations

Quick response during emergencies keeps everyone safe and protects the crane.

Emergency Stop

• Press the red emergency stop button on either the remote or the crane's control panel.
• This immediately stops all crane movements.

Signal Loss

• If the remote signal is lost, the crane will automatically stop as a safety measure.
• Do not resume operation until the connection is fully restored and confirmed stable.

Maintenance & Battery Care for Remote

Taking care of your remote controller ensures it works reliably every day.

Battery Charging:Charge the remote's battery every day after use to avoid unexpected shutdowns.

Keep It Clean and Dry：Avoid exposing the remote to water, oil, or grease — this can damage buttons and electronics.

Button Inspection

• Before starting each shift, test all buttons to make sure they respond correctly.
• Report any faults immediately to avoid operational risks.

Keeping these maintenance habits will help your remote last longer and keep your crane running smoothly.

Operating Tips for Mexican Port & Yard Conditions

Working in busy port yards like those in Mexico means dealing with tight spaces, changing weather, and lots of activity. Here are some practical tips to keep your crane running smoothly and safely in these conditions.

Avoid High-Speed Travel in Narrow Yard Lanes

• Slow down when moving the crane through tight or crowded lanes.
• This helps prevent collisions and gives you more control over the load and crane movement.

Use Circle-Turning Mode for Tight Corners

• When maneuvering around stacked containers or confined spaces, switch to the 45° circle-turning tyre position.
• This angle lets the crane turn more smoothly without needing extra room.

Reduce Hoisting Speed During High Winds

• Strong winds can make the load swing dangerously.
• Slow down your lifting and lowering speed to keep the load steady and prevent accidents.
