For a jib crane, you need a hoist that matches the weight of the load to be lifted, the working environment, and the desired operation. The most commonly used options are the chain hoist and the wire rope hoist, with electric variants being preferred for frequent use or heavy loads. In this article, we answer the most frequently asked questions about choosing the right hoist for your jib crane.
What are the different types of hoists for a jib crane?
For a jib crane, there are three main types of hoists: the chain hoist, the wire rope hoist, and the strap hoist. The choice depends on the lifting capacity, the lifting height, and the frequency of use. Chain hoists are compact and robust, wire rope hoists are suitable for greater lifting heights, and strap hoists are used when lifting sensitive or fragile loads.
Each type has its own area of application:
- Chain hoist: Suitable for loads up to several tonnes, compact in size, and resistant to harsh working conditions. Available in manual or electric versions.
- Wire rope hoist: Ideal for greater lifting heights and heavier loads. The steel cable offers more flexibility in lifting range and is standard in industrial environments.
- Strap hoist: Less commonly used on jib cranes, but valuable when the surface of the load must be protected, such as with painted structures or machine parts.
In addition to the type of hoist, the suspension also plays a role. On jib cranes, the hoist is attached to the boom and travels along the arm. Therefore, always ensure that the running weight of the hoist is included in the load calculation of the crane.
What is the difference between a chain hoist and a wire rope hoist?
The main difference between a chain hoist and a wire rope hoist lies in the lifting medium and the range of applications. A chain hoist uses a steel chain as the lifting element and is compact, durable, and resistant to dirt. A wire rope hoist uses a steel cable, which allows for greater lifting heights and higher lifting speeds.
Chain hoist: advantages and limitations
Chain hoists are particularly suitable for environments where robustness is required, such as in the metalworking industry or outdoor storage. The chain is resistant to heat, wear, and mechanical stress. A disadvantage is that chain hoists become impractical at large lifting heights, as the chain takes up a lot of space when coiled.
Wire rope hoist: advantages and limitations
Wire rope hoists are the standard choice in production environments with greater lifting heights. The steel cable is lighter than a chain of comparable strength and can be wound onto a drum, making large lifting heights manageable. One point of attention is that steel cables are more susceptible to corrosion and must be regularly inspected for wear and wire breaks.
How much lifting capacity does a hoist for a jib crane need?
The required lifting capacity of a hoist for a jib crane is at minimum equal to the maximum weight of the load to be lifted, including the weight of any lifting equipment such as chain slings, lifting straps, or grabs. In practice, a safety margin is always maintained above the nominal working weight.
When determining the lifting capacity, the following factors are important:
- Maximum load mass: The heaviest object you will ever want to lift with the crane.
- Weight of lifting equipment: Chain slings, lifting straps, and spreader beams count towards the total load.
- Dynamic load: When lifting quickly or stopping suddenly, forces arise that are higher than the static weight.
- Lifting capacity of the jib crane itself: The hoist must never have a higher lifting capacity than the maximum load of the crane arm.
As a rule of thumb: choose a hoist whose nominal lifting capacity is at minimum equal to the maximum load, but always align this with the overall structure of the jib crane.
When should you choose an electric hoist for a jib crane?
An electric hoist on a jib crane is the right choice when loads are lifted frequently, when the weight of the load makes manual lifting impractical or unsafe, or when precise positioning is required. For loads above 500 kg or more than ten lifting movements per day, an electric hoist is almost always the better solution.
Electric hoists offer a number of concrete advantages over manual variants:
- Higher lifting speed, which increases productivity.
- Less physical strain on the operator, contributing to safety and ergonomics.
- The ability to fine-tune the lifting speed, useful when placing heavy components.
- Easy integration with control systems or overarching crane controls.
Manual chain hoists remain useful for occasional use, low lifting frequency, or at locations without available power supply. In fixed production installations, however, the electric hoist is the standard.
What safety regulations apply to hoists on jib cranes?
Hoists on jib cranes must comply with the European Machinery Directive and the associated standards, including EN 14492 for powered hoists. In addition, periodic inspections are mandatory in accordance with occupational health and safety legislation and the NEN standards for lifting and hoisting equipment. In the Netherlands, an annual inspection by an accredited inspection body is legally required.
The most important safety rules at a glance:
- Working Load Limit (WLL): Never exceed the maximum working load as indicated on the hoist and the jib crane.
- Annual inspection: Have the hoist and the complete crane system inspected and certified annually by a certified party.
- Visual inspection before use: Before each lifting movement, check the chain or cable for damage, the hook for deformation, and the fastenings for wear.
- Use of certified lifting equipment: Only attach lifting equipment with a valid CE marking and visible WLL indication to the hoist.
- Overload protection: Electric hoists must be equipped with an overload protection device that interrupts the lifting movement when the maximum working load is exceeded.
How do you choose the right hoist for your specific situation?
You choose the right hoist for your jib crane based on four criteria: the maximum lifting capacity, the required lifting height, the frequency of use, and the working environment. By systematically working through these four factors, you arrive at a choice that is both technically and practically suited to your situation.
Follow these steps:
- Determine the maximum load: What is the heaviest object you want to lift, including lifting equipment?
- Determine the lifting height: How large is the height difference between the starting position and the end position of the load? For large lifting heights, a wire rope hoist is more practical.
- Estimate the frequency of use: Do you lift occasionally or multiple times per day? For frequent use, an electric hoist is almost always the better investment.
- Analyse the working environment: Is the environment humid, dusty, or hot? Then choose a hoist with the appropriate protection class and material specifications.
- Check compatibility with the jib crane: The hoist must fit the travelling gear of the crane arm and the total weight must not exceed the maximum load of the jib crane.
Still in doubt after going through these steps? Then seek advice from a specialist who can assess the complete situation on-site.

Frequently Asked Questions
Can I replace an existing manual hoist with an electric hoist on my jib crane?
This is possible in many cases, but does require a technical check of the jib crane. Verify whether the travelling gear and the crane arm are suitable for the higher weight of an electric hoist, and ensure that a suitable power connection is available. Always have this conversion assessed by a specialist.
How often should I replace the chain or steel cable of my hoist?
There is no fixed replacement interval; this depends on the intensity of use, the working environment, and the wear observed during inspections. As a rule of thumb: replace a chain if there is visible deformation, cracks, or more than 5% wear on the links, and a steel cable if there are multiple wire breaks in one lay length. Always have doubtful cases assessed by a certified inspection body.
What happens if I use a hoist with a higher lifting capacity than the jib crane can handle?
This is a dangerous situation that you must avoid at all times. The maximum load of the complete system is determined by its weakest component, in this case the jib crane. Overloading can lead to structural failure, collapse, or serious accidents. Always ensure that the lifting capacity of the hoist and the maximum working load of the jib crane are matched to each other.
Which hoist is most suitable for use in a humid or outdoor environment?
For humid or outdoor applications, a chain hoist with a stainless steel chain or a hoist with a high IP protection class is preferable. Wire rope hoists are also applicable in such environments, but require extra maintenance due to the corrosion susceptibility of the steel cable. If in doubt, ask about a hoist with specific corrosion protection, tailored to your working environment.
