While cranes and hoists take the spotlight, beam clamps deserve just as much attention. A beam clamp allows you to create an anchor point on a steel beam, eliminating the need for a permanent eye installation or gantry system, making them ideal for temporary fixes. Choosing the right clamps affects the safety and efficiency of structural engineers and site supervisors.

There are two major types of beam clamps in the UK: girder clamps and fixed beam trolleys or clamps. Girder clamps are designed for temporary lifts while fixed clamps offer support for monorails or point loads. Girder clamps come in screw-adjustable or spring-loaded which allows them to be secured on different widths. Flange width is very important to avoid uneven distribution of load and to prevent deformation of the beam under load.

Working load limitations are critical and should never be viewed as just a maximum number on a checklist. Manufacturers set beam clamps for a specific safe working load given a specific pulling angle, which is usually vertical. As soon as a sling or chain is rigged at an angle, the effective load on the clamp increases, sometimes significantly, regardless of whether the weight being lifted changes. All users specifying beam clamps on-site need to appreciate this phenomenon and configure the rigging to exert a force as close to vertical as possible, or choose clamps that are rated for the working load at the given angle.

Like chain blocks, wire ropes, and other lifting accessories, beam clamps are subjected to inspection and thorough examination requirements under LOLER. Beam clamps can more frequently be dropped or modified because they are used as loose tools. An inspection should be performed on a clamp to check the condition of the jaws, the integrity of the locking mechanism, any wear on the load pin, and that the identification tag or the marking of the safe working load is still properly visible. If the clamp fails an inspection or cannot be documented, the clamp should be readily withdrawn from service rather than being risked on a live lift.

When picking out a beam clamp, one must also consider the overall lifting plan instead of the one specific component. The clamp is but one element in a sequence involving the beam, the fixings, or welds that secure that beam, the sling, the hoist, and the load. The host beam engineer needs to confirm that the host beam can accept the point load applied, especially in older buildings where the initial design loadings did not consider a lifting point addition. This happens a lot in converted warehouses and manufacturing facilities with older repurposed steel frames, especially in buildings with significant alterations to the original design.

For more permanent setups, businesses that frequently lift loads from the same beams tend to find it more economical (over time) to have a dedicated fixed point installed, be it a lifting eye or a monorail trolley or a small gantry, than to have to keep rigging and de-rigging a temporary clamp. However, temporary clamps have their place, especially for one-off installations, maintenance lifts, or instances when the lift point needs to be mobile along the beam. Because of the safety-critical nature of this decision, working with a supplier who can best advise the appropriate type, rating, and inspection schedule for your specific application takes a lot of the guesswork away.

If you are responsible for the lifting equipment on a commercial construction site, you know that the paperwork is almost a job on its own. All wire rope hoists, chain blocks, gantries, and cranes are covered by what is known as LOLER (Lifting Operations and Lifting Equipment Regulations). Compliance on the paperwork with these regulations can mean the difference between a well-run commercial yard and a business that is at risk of enforcement actions, insurance claims, or worse – accidental injuries on the shop floor.

As for facilities managers and procurement teams, the real question is about how to organise a schedule that allows operation to continue while meeting the requirements. Lifting equipment used to lift people, this includes specific scaffold hoists and access platforms, require a ‘thorough examination’ every 6 months. Equipment that is used solely to lift loads – this includes most wire rope hoists, chain hoists, and cranes – is typically examined every 12 months, though this can depend on the outcome of a risk assessment specific to the application. Getting these intervals wrong, even by weeks, can invalidate coverage and create a liability gap that is very real.

A thorough examination is different than routine maintenance and it is important to clarify with suppliers and engineers which service you are booking. Maintenance is providing service to the equipment to keep it working smoothly day to day. A thorough examination, however, is a documented inspection that is performed by a ‘competent person’ who checks the structural integrity, brakes, hooks, wire rope, and safe working load markings, and other specifications, against the equipment’s design specifications. This report must be kept on file to be produced to an inspector upon request. A centralised system for recording inspection dates is beneficial for a company with multiple sites to save time when an inspection audit is performed.

A neglected or borrowed hoist, such as one bought second hand, a chain block that has been moved between depots, or a crane accessory that has been left in a workshop corner, will often slip through the cracks of a formal inspection if there is no one system that tracks every asset. It is worthwhile to create a simple identification system, such as a tagged serial number or a barcode, so that each hoist, gantry, or lifting accessory has easy access to its examination history. This is helpful when equipment is decommissioned, sold, or transferred between departments because it ensures that there is a clear record of ownership for both the seller and the buyer, protecting them from liability.

Understanding the right supplier for new equipment and ongoing servicing is something that most businesses do not recognise the importance of. A supplier who understands the loads, environment, and frequency of use on your site is able to advise on appropriate examination intervals and identify wear patterns before they pose an issue, rather than just signing off a compliance box once a year. This is very significant in the case of wire rope hoists and cranes in particularly demanding construction site conditions, where the weather, dust and heavy cycling as operational conditions will wear and tear elements much faster than a standard inspection interval would predict.

In the end, LOLER compliance, when done properly, should actually offer operational benefits, not headaches. A solid, well kept examination schedule minimises unexpected downtime, prolongs the life span of expensive lifting assets, and demonstrates to clients and principal contractors that safety is a priority for your site. For businesses with lifting equipment, getting the inspections right is time well spent, as it reduces operational risk and enhances the flow of work.

Wire rope hoists are common instruments of occurrence in places where heavy duty work i.e. lifting and hoisting objects of immense weight is required. That directly takes your mind to such places as industries and companies where those kind of tasks are undertaken day in day out for process continuity. They have become machines of tremendous reliability as well as adaptability. Being heavy duty machines as they in fact are, they are operated by electricity. However you should not mistake it as being a complicated or complex piece of machinery in terms of its principle of operation as well as its material components that make it.

In the early 1800’s when its use started becoming more pronounced, mostly in the mining business, the wire rope was made from strands of steel that were wrapped around a hemp centre. As it was discovered then, this particular combination was sturdier and better grounded as opposed to other options as chain ropes. Today’s versions of hoists still employ the same basic technique as was used in the 1800’s with the rope strands having been wrapped around a central material made of either hemp, sisal, jute among other characteristic centre materials. However they come in different sizes in terms of the type of centre used and wires wrapped around it to compensate the different and specific industrial applications available. The ropes themselves are made of different materials with stainless steel being the prime one. It cannot be overstated how strong and durable these ropes are as opposed to your run in the mill type. This is all aimed at crafting a piece of machinery that can lift weights that are multiple times its own and with ease at that.  Continue reading →
