Crank Handles

Crank handles, also called crank arms, are mechanical hand-operated devices designed to operate various machinery and equipment manually. They typically consist of a rotating handle attached to a shaft. The handle’s rotational motion is translated into linear or rotary movement in the connected machinery. A crank handle is designed with easy grip and ergonomic to apply torque comfortably. These handles are made of rugged and tough materials, including durable thermoplastics, plastics, and metals. Steel crank handles ensure a longer-lasting performance than plastic crank handles. Additionally, crank handles come in varied sizes, shapes, and types, depending on the intended applications.

Popular Types of Crank Handles:

Crank handles come in various types, each designed for specific applications and requirements. Some common crank handle types include:

• Straight Crank Handles – These are simple, straight handles with a rotating crank mechanism. They are commonly used to operate machines, equipment, or tools manually.
• Foldable Crank Handles – Folding crank handles are designed to fold down when not in use, reducing the overall profile and potential for snagging.
• Revolving Crank Handles – Revolving crank handles have a revolving grip for more comfortable and ergonomic operation, especially when frequent or continuous turning is required.
• Adjustable Crank Handles – Adjustable crank handles feature a mechanism to adjust the handle across the entire length, providing flexibility for different applications or user preferences.
• Ratchet Crank Handles – Ratchet handles are integrated with the ratchet mechanism, allowing incremental movement in one direction while the handles remain stationary during the return stroke.
• Indexed Crank Handles – Indexing handles make precise adjustments in a predetermined number of increments or positions.

Other Crank Handle Types Include:

• T-Handle Crank Handles
• Ball Knob Crank Handles
• Folding T-Handle Crank Handles
• Hand Wheel Crank Handles
• Spinner Crank Handles
• Finger Crank Handles
• Crank Handles with Folding Cranks
• Detachable Crank Handles
• Square-Drive Crank Handles
• Hex-Drive Crank Handles
• Spline-Drive Crank Handles.

Typical Applications of Crank Handles:

Crank handles are commonly used in industrial applications where manual or mechanical effort is required to move or manipulate objects. Some typical applications of crank handles include:

• Adjustable Desks
• Manual Car Jacks
• Mechanical Toys
• Window and Awning Openers
• Grain Mills
• Hand-Cranked Generators
• Emergency Radios
• Treadle Sewing Machines
• Manual Meat Grinders.
