Crane pendant controller

Introduction to Crane Pendant Controllers

The Crane Pendant Controller is primarily designed to control various crane actions, including starting, stopping, and directional movement. It offers a reliable solution for crane and hoist operations in both indoor and outdoor environments. Below is a detailed description of its applications, operation methods, safety features, and maintenance requirements.

Application Scope and Working Environment

The Crane Pendant Controller is suitable for control systems operating at:

• AC power: 50Hz or 60Hz, voltage up to 380V.
• DC power: Working voltage up to 220V.

Designed for outdoor use, the controller is resistant to rain, snow, and dust, making it ideal for applications such as cranes and electric hoists.

Operation Methods and Features

The Crane Pendant Controllers operates through buttons on the control handle, offering the following key features:

1. Emergency Stop Switch:
   Equipped with a rotary-reset mushroom-head emergency stop switch, it allows quick motor shutdown in emergencies.
2. Directional Control:
   Buttons feature international arrow symbols, and opposing direction buttons are mechanically interlocked to prevent simultaneous operation.
3. Cable Suspension:
   The handle is suspended using soft, thin steel wires beneath the electrical box to prevent cable strain and potential core damage.

Safety Features and Protection

1. Waterproof and Durable:
   The controller is designed to withstand harsh environments, ensuring consistent performance.
2. Low Control Voltage:
   Button control voltage is limited to 36V, guaranteeing operator safety during use.
3. High Protection Rating:
   With a protection level of IP65, the controller resists water and dust, maintaining functionality in extreme conditions.
4. Insulation and Resistance:
   High-quality insulation ensures safety and operational reliability even in damp or adverse environments.

Maintenance and Care

To ensure long-term stability and functionality, follow these maintenance tips:

1. Button and Emergency Stop Check:
   Regularly inspect buttons and the emergency stop switch to confirm proper functionality and quick reset capability.
2. Symbol Visibility:
   Ensure button labels remain clear and visible for intuitive operation.
3. Suspension System Integrity:
   Check the handle’s suspension system to confirm it is securely fastened, preventing excessive cable strain or potential damage.
4. Environmental Protection:
   Store and operate the controller in conditions that minimize prolonged exposure to extreme elements.
