Points to consider when purchasing roll containers
There may be large price differences in roll containers and finding out all differences can take quite some time. Ultimately, everyone wants as much as a possible value for his or her money. When purchasing a new or used roll container, keep the points of attention below in mind, so that you purchase the right container with the features and benefits that you are looking for.
If there is limited space available for the storage of the roll containers, then it is advisable to consider nestable (retractable) roll containers. These can save up to 75% in space, compared to models that are not nestable. L-frame and A-frame
Two of the most common forms of nesting are those in an L-shape (with an L-frame) or in an A-shape (with an A-frame). An L-frame saves more space than nesting with an A-frame, but also requires extra handling when nesting, compared to an A-frame. Moreover, nested A-frame containers are easier to transport, whether or not in a whole row.
The durability of a roll container depends, among other things, on the materials used and the finish of the various components. These can be subdivided into the casing, the base and the wheel housing.
The conversion of a roll container is usually made of metal. The durability of a metal casing depends largely on the finish. In order, from least to most durable, the most common finishes are paints, powder coating, hot-dip galvanizing and galvanizing. Galvanizing is possible in two ways: electrolytic and thermal, with hot-dip galvanizing being the most high-quality version. Roll containers made of hot-dip galvanized steel can be placed outside in the rain without any problems because this finish prevents rust and cracks.
There are three types of material available for the base of a roll container: wood, plastic and steel. Wood generally costs the least and steel the most. Wood lasts the least and steel is the most durable and can bear the most weight. Plastic is in between the other two in terms of sustainability and price.
How is the wheel attached to the car? A multiple screw connection provides more load capacity, stability and is more durable in use. Also, note the type of wheel bearing used. A plain bearing is the simplest variant. Cheap and easy to maintain, but less suitable for containers that are moved over long distances. Roller bearings have a higher load-bearing capacity than plain bearings, so they are better suited for larger loads and have a lower rolling resistance than plain bearings, making them easier to drive. Ball bearings cost the most but have the highest bearing capacity and the lowest rolling resistance of the three.
In addition to the aforementioned ball bearings, which can ensure a lower resistance, it is also interesting to look at the diameter of the wheels and the fence type of the roll container.
Plug-in or clamping gate
A roll container often comes with an insertion gate or a clamping gate. If you want to nest many containers as quickly and comfortably as possible, a container with a clamping gate is the best choice. With a simple foot movement, these can be released and unfolded quickly and easily.
The bigger the wheel, the easier it is to get over obstacles or dirt parts and therefore reach your destination faster.
Ease of use
For many people, the ultimate convenience of the roll container in daily use is also a consideration in the purchase. Below are a number of examples of functionalities of a roll container that can be used easily.
Swivel and fixed wheel
Do not underestimate what difference the right type of wheel can make! Of course, you have to choose between the swivel and fixed wheels. Swivel wheels make a container manoeuvrable but are more difficult to steer with a heavy load and are therefore often used in combination with fixed wheels (which travel one way).
Material selection wheel
The choice of materials for the wheel is also worth considering. Soft material (such as rubber) makes less noise, absorbs more shocks and makes no stripes, while harder material (such as PP / Polypropylene) does not have those properties, but is generally cheaper to purchase.
