Manual Chain Hoists
Whether working with heavy HVAC equipment or staging a large theatrical production, manual chain hoists are a versatile option for a wide range of applications. Hoist Zone offers a variety of manual hand chain blocks from quality brands like CM and Black Bear.
Before deciding on the right manual chain hoist, consider factors such as operation type, load capacity and lifting speed. Then, select the model with a maximum lift height that fits your application.
Safety
Unlike electric hoists, manual chain hoists do not require a power source to function. They are also typically cheaper than powered hoists, making them ideal for budget-conscious operations. In addition, they have several safety features that prevent injuries and accidents. These include a stopper assembly that prevents the load from being unintentionally lowered and high-class, heat-treated load chains with breaking stresses of over 1000N/mm2 (100kgf/mm2). They are manufactured using carefully selected, fully processed special steel alloys and undergo rigorous quality control testing.
Another key safety feature of manual chain hoists is their reversible pawl design, which allows the operator to back-out the pawl and reset the brake quickly. This is essential for preventing accidental loading and unloading of the hook. In addition, the pawls can be locked in the neutral position when not in use.
Lastly, a manual chain hoist can be easily dismantled for maintenance and inspections. However, it is manual chain hoists important to follow any safety laws and instructions in order to avoid injuries or accidents. For example, never use a cheater bar on the operating lever and never use more than one person to pull the handle. Always check that the block is rigged securely and that the chains aren’t wrapped around each other before operating the hoist. Additionally, it is important to regularly lubricate the pawls and load chains to reduce friction and extend their life.
Performance
A manual chain hoist is a simple mechanical device that can lift a significant amount of weight. These hoists are used in a variety of industries for rigging and moving loads in applications such as manufacturing, construction sites, maintenance work, emergency services and transportation.
One of the most important aspects to consider when purchasing a hand chain hoist is its weight capacity, which indicates the maximum load that it can handle. Choosing a hoist with a higher capacity will allow you to lift heavier loads without overstraining the operator.
Another important feature to consider is the hoist’s lift height, which is the maximum distance that it can travel while lifting a load. You’ll want to make sure that the hoist is able to lift the load to the desired location without having to use a ladder or other elevated platform to reach it.
A good quality manual chain hoist will have a load limiter, which prevents the operator from accidentally overloading the hoist by trying to lift more than its rated capacity. This can lead to the load chain catching on something or breaking, which could seriously injure the operator and damage the equipment.
A manual chain hoist is an excellent option for any business that needs to move heavy loads and does not require electricity for operation. In addition to being inexpensive and portable, they are also easier to maintain and repair than electric or pneumatic hoists.

Durability
With a manual chain hoist, you can lift loads of almost any size. A hand controlled loop of chain turns a gear system which, in turn, converts the small pulling force you apply into a high-efficiency lifting power. This highly reduces the stress exerted on a single person and enables you to perform tasks that would otherwise require multiple people.
The gears are made from special, durable materials and developed according to holistic principles to ensure a long service life. They operate with minimum manual effort thanks to pre-lubricated ball bearings and precision machined drive train components. They are resistant to corrosion and designed for the harshest of environments. The load chain is heat-treated and made of case hardened strands to ensure maximum wear resistance. A built-in overload limiter protects the hoist mechanism from damage if you attempt to lift more than the rated capacity.
PS: One thing that I don’t really see much of on powered [electric] hoists, particularly in the hire market, is a chain collecting bag. This is a bit of a negative because the excess chain can hang down and get in the way when you’re working, especially if you’re stood up on the floor level of a building or on a mezzanine.
KITO offers a complete range of manual chain hoists in capacities from 1/4 to 20 tons. Each comes equipped with a hand chain, a safety hook top and bottom, a load chain, a spliced chain container and is provided with a certificate of load testing.
Maintenance
The compact design of manual hoists makes them easy to use in tight spaces, as well as environments where electrical power or air supply is not readily available. They are a versatile piece of equipment used in rigging across countless industries including automotive, construction sites, manufacturing, maintenance, emergency services, entertainment and transport.
With proper care and routine inspections, manual chain hoists can remain a durable piece of equipment for years to come. As part of the maintenance process, it’s recommended that the hoist chain be lubricated every few months using a high quality grease to ensure long life.
In addition to regular lubrication, it’s important that all hoist equipment is inspected and tested on a daily basis for safety and performance issues. The crane or hoist operator should conduct a manual chain hoists visual inspection of their equipment each day, and a more in-depth inspection each month to document any existing damage or wear and tear on the equipment. Additionally, a service load test should be performed on the hoist each quarter to observe how well it functions under various conditions and loads.
At Tiger Lifting, we have a wide variety of manual chain hoists that are designed to meet the needs of your specific application. For example, we offer spark-resistant hoists for use in potentially dangerous areas that would otherwise not be suitable for an electric or pneumatic (air) hoist.
