A beam trolley is designed to enable travel, allowing lifting equipment to travel along a beam. They are usually used alongside a chain hoist and can have a range of features – they can also be used with a wide range of flange widths due to their adaptability. The main reason to consider a beam trolleys is to ensure safe, smooth travel along an l beam, promoting the efficient movement of goods of a wide variety of weights. The capacity of a beam trolley can vary greatly and there will be options for all kinds of applications.
In terms of their general design, a beam trolley consists of side plates that have two wheels each. These side plates are exactly the same and are securely attached to the wheels, allowing the traverse of objects along the track. The wheels and plates are secured together with a threaded suspension point, which is also where the hoist is suspended. If a hoist is not being used, then the load may in fact be suspended here instead.
There are also various methods of operation depending on the load that is being moved and the type of beam trolley in use. Some beam trolleys will be manual, in which case they can aid lifting and loading by being pushed along the beam. This is easier than lifting the load by hand, but it is still a manual process and will not work with all loads. Sometimes geared and electric models might be used instead, which are more suited to lifting and moving heavier loads.
There are many different types of beam trolley with various features to meet different lifting and travelling needs. There are also many different brands, some of which will be better suited to different cranes and hoists, so check compatibility of brands before use. Beam trolley features can vary greatly from brand to brand but also within the same brand – features available will make them more or less suitable for different applications. These are some of the features to look out for on a quality beam trolley:
- Hardened heat treated steel wheels, which will help to provide reliable tracking
- Sealed ball bearings, which will provide smooth operation of the trolley and will help to prevent the need for costly maintenance in the long run
- A lightweight design which will help with smooth and simple operation
- Protective lugs and rubber buffers to hold the trolley on the beam in the right place and avoid damage
- A capacity that is suitable for the operations that will be carried out
- Full certification, along with a test certificate or an EC Declaration of conformity stating compliance with essential health and safety requirements, as laid out in the machinery directive 2006/42/EC
- An anti drop plate to prevent damage to the wheels if any contact is made with the end rail stoppers
- Machined steel wheels mounted on pre-lubricated encapsulated ball bearings
- Corrosion resistance (this is often only available on request, but availability indicates a quality system and a good supplier that is willing and able to be flexible)
