- Chain hoists are a very useful invention that can be used to lift heavy equipment and other items all while minimizing the level of manpower and effort required to get the job done.
- DQCRANES supply types of chain hoists, come in various sizes and lifting capacities, and can be found in venues such as auto repair workshops to construction sites when used with jib cranes and bridge cranes.
- The chain hoists we offered include polipastos eléctricos de cadenas, manual chain blocks and lever chain hoist, it can pay back many times the investment due to the efficiency it provides for lifting purposes.
- Welcome to contact us, we can help you decide which chain hoist is best suited for your application.
Chain hoists are a very reliable method of handling heavy loads and are used commonly in warehousing, construction, and on other commercial and residential applications. Electric chain hoist, hand hoist, or lever hoist? These systems may all seem very similar, but do you know how does each type of chain hoists work and what are the specific benefits?
How Does a Hand chain hoist work?
- Hand chain hoist also called chain block, a hand chain hoist is driven by a manually-controlled chain loop that turns a chain wheel. This chain wheel is attached to a short driveshaft and gear system. It multiplies the input to drive a slow-moving high-torque gear for hoisting or lowering the load. This gear system also contains a brake pawl to prevent the load from slipping.
- The gear system is designed to allow for minimal effort (input) from the operator, meaning that lifting loads are done more easily and with less strenuous input.
- Each chain hoist will have a maximum load capacity that is directly related to the gearing used. What this means is that the input from the hoist operator stays the same, the load capacity increases, but the speed at which the load is hoisted or lowered reduces significantly.
How Does Electric Chain Hoists Work?
- Electric chain hoists are operated using a pendant or radio control as opposed to the physical control of a manual chain hoist. This improves the ease of operation and reduces the chances of injury because the operator can stand away from the load while lifting it.
- While there are different duty cycles, most electric motors are capable of operating at a high torque for around 30 minutes. It also implements an electric and mechanical braking system to hold the load in place.
- For the majority of electric chain hoists, customers can choose single-speed, dual-speed options. While single-speed is more commonly used, dual-speed hoists are better when there is a need for more precise movement and maneuvering of loads.
- Electric chain hoists are also able to incorporate smart technologies that improve operation, such as systems that automatically adjust lifting speed to reduce lateral load movement. This also means more safety features and sensors to prevent overloading the hoist.
How Does a Lever Chain Hoist Work?
- A lever chain hoist is the lowest profile and arguably the cheapest hoist solution available. It is a simple system made up of a geared ratchet that is operated by a hand-sized ergonomic lever.
- Free-chaining disengages the ratchet mechanism from the chain so that you can manually reduce or increase the chain length. This is usually for the process of attaching or removing the load from the hook because it allows you to take up or reduce slack in the chain.
- Most lever systems are designed to be incredibly simple to use with just one hand. They generally can lift up 1 ton to 9 tons.
- A lever hoist is ideal when you need it portable and infrequent – for example, to aid in installations on multiple sites. It’s an incredibly flexible and practical hoisting solution for low-use cases.
