How to Choose Overhead Hot Cranes for Different Kind of Loads?

HOT cranes stands for Hoist One Track cranes. These are types of overhead cranes that are commonly used in industrial settings to move goods. Overhead HOT crane are lifting devices that are used to move the load from one side to another. Hoist HOT cranes are not too tough to maintain either.  

Depending upon the load supported by hoists they can be divided into wire rope hoists or chain hoists. Let us discuss what these hoists are and what are the advantages and disadvantages of both. 

CHAIN HOISTS

A metal chain is used as lifting medium in chain hoists. These hoists use a hook connected to a chain and are designed to lift the load vertically. Chain hoists can be operated manually, electrically, hydraulically or pneumatically. They are a popular choice as they are relatively low maintenance and cheaper than wire rope hoists. However, HOT Crane Manufacturers suggest the use of this hoist in applications where the weight is below five tonnes as they have a lower lifting capacity. 

Following are the advantages of using chain hoists. 

Good value for money

Even though the lifting capacity of the chain hoist is lower than the wire rope hoist, it turns out to be a much more economical option. However, it does allow you lift more weight than a manual hoist would. 

Very flexible

Chain hoists can be easily transported between different sites thus making it a very flexible option. It is especially useful for construction industry as there is a need to move the hoist from one site to another. 

Easy to achieve vertical lift

Since there is no room for lateral movement chain hoists can be used with a variety of lifting equipment like jib cranes and gantries. 

Easy to limit switches

You can easily set the minimum and maximum path with the help of upper and lower limit switch. This protects the load from human error. 

Disadvantages

Limited lifting capacity

One of the major disadvantages of a chain hoist is that it has a limited lifting capacity, usually under five tonnes. This makes it redundant for applications where heavy loads need to be move. 

Can snap immediately

A wire rope hoist will disintegrate strand by strand, however, a chain hoist can snap immediately. This can be avoided with regular inspection and maintenance. 

WIRE ROPES

A wire rope hoist is used as a lifting medium in applications and industries where heavy loads, up to 20 tonnes, need to be moved. They perform lifts at a faster speed than chain hoists. Crane manufacturers make these hoists which can be powered manually, electrically, or pneumatically.

Advantages of wore rope hoists

Made for heavy lifting

Wire rope hoists can lift heavy loads as compared to chain hoists. These hoists are made using multiple wires which allows it to distribute the weight. venus engineers are of India’s leading Overhead HOT crane manufacturers.

They are very safe

Since there are many wires used to make these hoists, it means that even if one of the wires breaks or snaps they will still be able to hold on to the load and lower it safely. 

High resistance

Wire rope hoists are resistant to corrosion, rust and abrasion, thus less likely to get spoilt. You can even go for a galvanised hoist which will offer even greater protection. 

Disadvantages

Require huge space

Since they are made for lifting heavy loads they are also big units themselves. Thus, you plant or site should have enough space to install these hoists. HOT cranes suppliers will suggest wire rope hoists only if there is enough space available. 

Very expensive

Wire rope hoists are a more expensive option than chain hoists.

What are the different kinds of HOT cranes?

HOT cranes stands for Hand Operated Travelling cranes. These are types of overhead cranes that are commonly used in industrial settings to move goods. Overhead HOT cranes are lifting devices that are used to move the load from one side to another. HOT crane, or any other crane for that matter, is suited for both indoor and outdoor requirements. Hoist HOT cranes are not too tough to maintain either.

Let us see the different types of HOT cranes available

Bridge Cranes

These are the most commonly used type of HOT cranes. Two parallel runways are fixed onto the structure of your building with a travelling bridge covering the gap. There are two configurations available in these cranes: single girder and double girder. The strength of both single and double girder is roughly the same, but you can lift goods higher with a double girder. A single girder is easier to install and costs cheaper as well. HOT crane manufacturers can make adjustments to the size of the crane cater to your needs.

Gantry Crane

In the case of gantry cranes, the girder is supported by freestanding legs as opposed to being fixed onto the structure of the building like bridge cranes. The legs of the crane can be nailed into the surface or fitted underground. These type of cranes are ideal for outdoors as there is no need to look for place to fix the crane onto the structure. They also come in single-girder and double-girder configurations. Crane manufacturers like Venus Engineers have a complete range of cranes that are essential to move and lift heavy goods.

Monorail Cranes

A monorail does not have a girder, but instead it has a trolley connected to an I-beam that moves the hoist. These cranes are mostly used to move the load in a restricted area. A monorail generally allows only for straight line movement, but they can be customised. This is a cheaper option than installing bridge or gantry cranes. HOT cranes suppliers can help you in creating a monorail crane that improves your productivity. 

Jib Cranes

Jib cranes consists of pillars that is mounted on the floor or fixed on the wall. The crane has horizontal a working arm called the jib, which is attached to a movable hoist. A job crane moves in circular motion and it optimises the floor space owing to a small radius. Even though they do not use up a lot of space, they can still be used to lift loads weighing several tons. Overhead HOT crane manufacturers can also design this leg with self-supporting legs with its own support column. 

Workstation Cranes

This lift is ideal for lightweight use and places where there is limited space available. They are best suited for operations that are going to be repeated again and again like moving packaged boxes from one side of the warehouse to another. They can be made both in single-girder and double-girder configurations. They can be freestanding, ceiling-mounted or even monorail systems. 

Top-running and under-running cranes

In top-running cranes the bridge runs along the rails on top of the runway beams. These cranes are made for lifting medium to heavy-duty weights. Their capacity can be built to hold capacities from 25kgs to hundreds of tons. They come in both single-girder and double-girder configurations.

An under-running bridge is supported by the bottom flange of the beam. These lifts are mostly made to lift lower-capacity loads, hence are most commonly available in single-girder configuration. An under-running lift can also be made with freestanding legs if the structure of the warehouse does not support wall-mounted columns.
