The Thing You Need To Know About Hand Hoist For Crawler Crane

Hand hoist, also commonly referred to as a hand chain hoist or manual hoist, is a versatile and compact lifting device widely used in various industries. This type of hoist operates by manually pulling a chain or lever, which in turn activates a set of gears to lift and lower heavy loads. The hoists are prized for their portability, ease of use, and ability to provide precise control over lifting operations.

To make an informed decision when selecting a hand hoist for your crawler crane, it is crucial to have a basic understanding of its key features and functions.

How does a hand hoist work?

At the core of a hand hoist is the hand chain, which is manually pulled by the operator. The hand chain is connected to a set of gears housed within the hoist mechanism. As the operator exerts force on the hand chain, the gears engage and start rotating, creating a mechanical advantage.

This gear system is responsible for multiplying the force applied by the operator, effectively reducing the physical effort required to lift the load. As the gears turn, they drive a load chain that is directly connected to the load itself.

To facilitate the lifting process, the load chain passes over a chain wheel or load sheave within the hoist mechanism. When the operator pulls the hand chain in one direction, the load chain is drawn in, causing the load to be lifted. Conversely, when the operator releases the hand chain or pulls it in the opposite direction, the load chain unwinds, allowing for controlled lowering of the load.

Safety is a critical aspect of hand hoist operation. To ensure secure lifting and prevent unintended load movement, the hoists are equipped with a brake system. This brake engages automatically when the operator stops pulling the hand chain, holding the load in place and providing stability during lifting operations. The brake also facilitates controlled descent when lowering the load.

what's the difference between manual hoist and eletric hoist?

A manual hoist operates through manual force exerted by the operator. It typically consists of a hand chain or lever that the operator pulls or cranks to initiate the lifting and lowering process. By employing a system of gears, the hoist provides mechanical advantage, reducing the physical effort required by the operator. These hoists are known for their compact size, portability, and independence from external power sources. They are commonly used in situations where power availability is limited or when precise control over lifting operations is necessary.

In contrast, an electric hoist relies on an electric motor for its operation. The motor powers the lifting mechanism, eliminating the need for manual effort. Electric hoists are controlled using push-button pendants or remote controls, enabling operators to initiate lifting and lowering actions from a safe distance. Electric hoists are recognized for their efficiency, speed, and capacity to handle heavier loads compared to manual hoists. They require an electrical power supply, such as an outlet or a dedicated power source, to function.

different power source

Manual hoists rely on human power, providing mechanical advantage through gear systems. Conversely, electric hoists employ electric motors to facilitate lifting operations, enabling higher capacities and faster speeds. 

different Control Mechanism

Manual hoists are controlled directly by the operator’s manual actions, such as pulling a hand chain or cranking a lever. Electric hoists are controlled using push-button pendants or remote controls.

different application

Manual hoists offer portability and versatility, making them suitable for applications where power is limited or precise control is critical. Electric hoists, with their increased lifting capacity and automation capabilities, are commonly employed in industrial settings that involve heavier loads and require efficient operation.

what's the difference between a manual hoist trolley and a hand hoist?

A manual hoist trolley and a hand hoist are two distinct components used in material handling operations. While they share similarities in terms of manual operation, they have different functions and applications.

Manual hoist trolley

A manual hoist trolley is designed to enable horizontal movement of a load along an overhead beam or track. It typically works in conjunction with a hoist. Equipped with wheels or rollers, the trolley runs along the beam, allowing for smooth traversal along the length of the structure. By attaching the load to the trolley, operators can easily move it horizontally within a defined area. The trolleys are operated by hand, either through pushing or pulling, facilitating precise positioning and transport of heavy objects.

Hand Hoist

In contrast, a hand chain hoist is specifically designed for vertical lifting and lowering operations. It relies on manual force exerted by the operator to raise or lower loads. The hoist is equipped with a hand chain or lever that the operator pulls or cranks to initiate the lifting or lowering process. Through the use of gears and mechanical advantage, the hand hoist reduces the physical effort required by the operator. Hand hoists are often compact, portable, and independent of external power sources. They find applications in situations where power availability may be limited or when precise control over lifting operations is required.

While both the manual hoist trolley and the hand hoist involve manual operation, they serve different purposes. The trolley enables horizontal movement of loads along an overhead beam or track, while the hand hoist is specifically designed for vertical lifting and lowering. By understanding their distinct functions, operators can choose the appropriate tool for the specific material handling task at hand.

what must you ensure you never do when using a hand chain hoist?

When using a hand chain hoist, there are several important precautions that should be taken to ensure safe and effective operation. Here are some things you must ensure you never do when using a chain hoist:

  • Exceed the rated capacity: Never attempt to lift a load that exceeds the maximum weight capacity specified by the manufacturer for the hand chain hoist. Overloading the hoist can lead to equipment failure, accidents, and injuries. Always check the load weight and ensure it falls within the hoist’s rated capacity.

  • Stand under a suspended load: Never position yourself or anyone else under a load that is being lifted or suspended by the hoist. In the event of a failure or accidental release, falling loads can cause severe injuries or even fatalities. Maintain a safe distance from the load and the hoisting area.

  • Jerk or abruptly stop the hoist: Never jerk or abruptly stop the hand chain hoist while lifting or lowering a load. Smooth and controlled movements are essential for safe operation. Sudden stops or jerky motions can cause the load to swing, destabilize the hoist, or put excessive strain on the equipment.
