Differences Between Double Rim Crane Wheel and Single Rim Crane Wheel

 

The wheel is mainly composed of a tread and a rim. The tread is used to support the weight of the crane and make it run. The rim is used to guide and prevent the crane from derailing. Usually installed on the main beam or support structure of the crane.

 

The wheel is one of the main parts of the lifting machinery operating mechanism. Crane wheels are divided into three types according to their uses:

(1) Traveling wheels on rails, usually large and small car wheels of bridges and gantry cranes;

(2) Suspended wheels, running on the lower flange of the I-beam of a single-girder crane

(3) Semi-circular grooved pulley wheels, used on the load-bearing ropes of rope cranes.

 

Wheels can also be divided into three types according to whether they have rims:

(1) Double rim wheels, used for running wheels of bridge and gantry crane carts;

(2) Single rim wheels, often used as running wheels for gantry crane trolleys;

(3) Rimless wheels, often used on cranes traveling on circular tracks and on tire-type container gantry crane trolleys.

 

The difference between double rim wheels and single rim wheels

 

1. Structural design:

 

Double rim wheels have two outer rims, one on each side of the wheel. This design increases the surface area of wheel contact with the track, improving stability and load-bearing capacity;

 

Single rim crane wheels usually have just one wheel attached to the bottom of the hoist truck via spokes or other structures. This design makes the crane easier to operate in narrow or limited spaces and allows for flexible positioning and movement.

 

2. Carrying capacity

Double rim crane wheels: This type of wheel usually has a higher load-carrying capacity due to the presence of two rims. They are able to withstand greater weight and are suitable for applications where heavy loads need to be carried.

 

Single rim crane wheel: The load-bearing capacity is relatively low, and it is usually suitable for small and medium-sized loads.

 

3. Stability

Dual rim crane wheels: Because the dual rims provide a wider contact area, these wheels are more stable when running, better able to distribute weight and reduce ground pressure.

 

Single rim crane wheels: slightly less stable than double rim wheels, especially when carrying heavy loads, more careful operation is required to ensure stability.

 

4. Usage scenarios

Double rim crane wheels: Suitable for occasions that need to carry heavy loads, have high stability requirements and where ground pressure control is important, such as large cranes, bridge cranes, etc.

 

Single rim crane wheel: Suitable for small and medium-sized loads, low tire interference requirements, and occasions where cost control is important, such as light cranes, gantry cranes, etc.

 

5. Cost and Maintenance

Double rim crane wheels: usually cost more due to their more complex structure and higher load-carrying capacity. At the same time, double-rimmed wheels may also require more cost and time when maintaining and replacing them.

 

Single rim lifting wheels: The structure is relatively simple and therefore usually less expensive. At the same time, maintenance and replacement are relatively easy and cheap.

 

In summary, there are significant differences between double rim crane wheels and single-rim lifting wheels in terms of structure, load-bearing capacity, stability and applicable scenarios. Therefore, when choosing, you need to make a reasonable choice based on specific needs and application scenarios.

 

In addition to double rim wheels, single rim wheels, and rimless wheels are often used in lifting machinery. The use of rimless wheels is to prevent rail gnawing caused by friction between the track rim and the track, but it is easy to derail and its use is limited. Use only when there is no risk of derailment. Their design focuses primarily on providing stability and flexibility. Compared with rimmed wheels, rimless crane wheels usually have a more simplified structure, with no obvious rim portion and contact with the ground mainly through the flat bottom tire or axle.

 

Features and uses of rimless wheels:

1. Bottom design

The bottom of rimless crane wheels usually adopts a flat design to ensure maximum contact area with the ground and provide stable support and movement.

 

2. Ground protection

Because rimless crane wheels have a simpler design, they are often able to spread the weight of the vehicle and reduce pressure on the ground, thus protecting the ground from damage. Suitable for some places with high ground pressure requirements.

 

3. Low speed operation

Because the design of rimless lifting wheels is more focused on providing stability and flexibility, they are generally suitable for low-speed moving and handling work.

 

4. Applicable scenarios

Rimless crane wheels are suitable for specific scenarios that require ground protection, have low rim interference requirements, and have limited space, especially in indoor operations and environments with high ground protection requirements.
