Common Types of Overhead Equipment Parts and Their FunctionsIn industries and warehouses, overhead equipment plays a crucial role in streamlining operations and maximizing productivity. This equipment is responsible for lifting, moving, and transporting heavy loads, making them indispensable in various sectors. To better understand the functioning of overhead equipment, it’s essential to familiarize ourselves with the common types of parts they consist of and their respective functions. In this comprehensive article, we will explore the different overhead equipment parts and delve into their functions, shedding light on the critical role they play.

Hoist Motor

The hoist motor is one of the primary components of overhead equipment. This powerful motor provides the necessary force to lift and lower heavy objects. It converts electrical energy into mechanical energy, allowing the hoist to perform its lifting function efficiently. The hoist motor is designed to handle significant loads while maintaining optimal safety standards.

Wire Rope

Wire ropes serve as the backbone of overhead equipment. They are composed of multiple strands of metal wire twisted together, providing exceptional strength and durability. These ropes are responsible for supporting the load being lifted by the equipment. Wire ropes are designed to withstand extreme tension and are crucial in ensuring safe and secure lifting operations.


The trolley is an essential part of overhead equipment that facilitates horizontal movement along the overhead crane’s bridge. It is typically mounted on wheels and can traverse the entire length of the bridge, allowing the operator to position the load accurately. The trolley is equipped with controls that enable precise movements, making it an indispensable component for efficient material handling.

Pendant Control

The pendant control, also known as the pendant station or pendant switch, is a handheld device that enables operators to control the movements of the overhead equipment. It consists of buttons or switches that correspond to different operations such as lifting, lowering, and horizontal movement. The pendant control provides operators with a convenient and intuitive interface to operate the equipment safely and effectively.

Load Block

The load block, also referred to as the hook block or lifting block, is the component that connects to the load being lifted. It consists of a hook or other attachment mechanism that securely holds the load. Load blocks are designed to accommodate various load sizes and weights, ensuring a secure connection during lifting operations. They are built with high-strength materials to withstand heavy loads and maintain safety.

Limit Switches

Limit switches are safety devices installed on overhead equipment to prevent overtravel and ensure safe operation. These switches are positioned at specific points along the crane’s travel path, such as the end of the bridge or the limits of the trolley’s movement. When the equipment reaches these predetermined positions, the limit switches trigger and halt further movement, preventing any potential accidents or collisions.

Control Panel

The control panel serves as the command center for the overhead equipment. It houses the electrical components, such as motor controls, relays, and circuit breakers, necessary for the proper functioning of the equipment. The control panel allows operators to monitor and control various aspects of the equipment’s operation, ensuring safe and efficient performance.


Brakes are critical components of overhead equipment that ensure safe and controlled stopping. They are installed in the hoist motor and trolley mechanisms to provide precise braking action when required. Brakes play a vital role in preventing load slippage and maintaining stability during lifting and movement operations.

Festoon System

The festoon system is an arrangement of cables and hoses that supply power and control signals to the moving parts of the overhead equipment. It consists of a trolley, which supports the cables and hoses, and a festoon track that guides the trolley’s movement along the crane’s bridge. The festoon system ensures the uninterrupted flow of power and signals, enabling smooth and reliable operation of the equipment.

Electromagnetic Brake

The electromagnetic brake is a specialized braking system used in overhead equipment to provide instant stopping power. It operates by applying an electromagnetic force to create friction and halt the movement of the equipment. Electromagnetic brakes are known for their quick response time and high braking torque, making them ideal for applications where precise and immediate stopping is required.

Frequently Asked Questions about Overhead Equipment Parts

What are the Safety Precautions for Operating Overhead Equipment?

Operating overhead equipment requires adherence to strict safety guidelines. Some key precautions include:

  • Conducting regular equipment inspections for any signs of wear or damage.
