Chain Hoists serve as a really useful lifting tool on a day to day basis for riggers. Lifting loads up to 50,000kg, that's a huge amount of pressure for such a machine, however, a chain hoist is built and tested to take the pressure of such activities. If maintained correctly and used within its capacities a well build industrial hoist should last for a very long time, we have seen GIS hoists in particular at almost 50 years old, still in action and running sound!
What is suitable maintenance?
Suitable maintenance programmes meet the requirement of the hoist and by this we mean based upon the usage of the hoist; if the hoist is used infrequently then you may find you only need to run a maintenance every 6-12 months, if the usage is more intense then maintenance might even need to be run every month. This would include essential checks to the hoists body, electrical panel, load chain and other vital components along with lubricating the load chain or wire...
A hydraulic system typically consists of hydraulic cylinders, pipes, and hydraulic fluid. The system, which can be used to lift heavy objects with ease, works on a very simple principle. When you apply force at one point of the system, it gets transmitted to another point through the hydraulic fluid. Normally, hydraulic cylinders come in pairs and are connected through a pipe. The cylinders, which should ideally stand perpendicularly to the pipe, have different diameters. The cylinders are partially filled with hydraulic fluid with oil being the most common option.
The empty space in the partially-filled cylinders allows the pistons to function. One cylinder will have a piston that will be larger than the piston in the other cylinder. At first, fluid is pushed into the compartment of the small piston and after the application of force, the fluid, which is incompressible, is pushed into the compartment of the big piston. This process promotes the movement of the big piston....
Hydraulic cylinders support manifold commercial and industrial operations. In fact, we often come across hydraulics in our daily lives. For example, the truck that collects trash features the hydraulic technology that can compress trash at the back of the vehicle. Recycling plants make use of hydraulic cylinders to squeeze fragmented metal and other substances. The hydraulic technology is used in flights to regulate mechanisms associated with flaps and landing gear. Besides, hydraulic systems are widely used in other industries such as mining, oil & gas, road maintenance & repair, material handling, and forestry.
A hydraulic cylinder works on a very simple principle. The cylinder barrel contains oil or some type of fluid. The barrel has a piston mounted inside it and it can be made to move in a linear route. The piston extends or retracts when force is exerted on the fluid. Hydraulic cylinders are designed taking into account the applications that they have to supp...
Ratchet Lashings make loads safe to transport on the back of trucks, trailers and lorries alike, not just that but even in the boot of your car or van by securing goods to the transport bed.
In this article, we outline the details of how they operate, when it's safe to use and the various different types. Still got questions? Pick up the phone and talk to the LES team today.
Ever wondered how to operate ratchet straps? My name is Will Dunn, I'm the Sales Director for LES and it is my pleasure to present to you the best practices and solid tips on how ratchet straps work. I will guide you through the different available ranges, styles and formats. From small 'disposable' assemblies to larger 75mm webbing capable of securing loads up to 5000kg/5000daN (or 5Tonnes).
Most often the case is that Ratchet Straps are really simple to operate, there is a misconception that I aim to break down and show you that they are not hard to use, you just have to learn to use them- perhaps that's the hard way? Who knows. What I do know is that our range is so simple to specify and even easier to use, read more to learn something new today! Once you learn, you won't forget it- I can promise you that.

Wire Rope Hoists are one of the most important components of gantry cranes and overhead cranes. Winch inspection and maintenance determine the life and functionality of your cranes and so you should make sure that you keep a regular winch maintenance plan in place. UK laws advise a service every 12 months at the very least, and more if the crane is used often. This will allow you to avoid costly repairs or replacement-related expenses in the future. A good rule of thumb is to ensure that you clean your winch immediately after a muddy or wet ride. When you use your winch quite often, you have to invest proper time in cleaning it.
Winches that remain caked in mud for a long time are more likely to wear out compared to the ones that are used less frequently and stored in dry places. However, winches that are not used frequently may still become dirty. In such cases, you may consider investing in winch covers. Neoprene winch covers are especially useful as they are made u...
Pallet jacks are used to lift loads that would usually demand the effort of multiple workmen for being lifted. The use of pallet jacks not only saves labour costs and time, but it is also a safe alternative for workers who need to lift hazardous materials. Surprisingly, many employers allow pallet jacks to be operated by untrained and unsupervised workmen, which make workers and onlookers vulnerable to injuries. When a worker in your facility operates a pallet jack, he should make sure that he uses protective gear, such as gloves, and steel-capped boots. Additionally, the use of safety eyewear is recommended if a job involves the transportation of hazardous chemicals.
There are certain precautions that you should adopt to ensure safe equipment use. It is not a good idea to operate the machine beyond its lifting capacity or to defy lifting instructions during loading and unloading operations. Ensure that you move the load slowly so that you can avoid incidents if your envir...
Industrial settings that use steel sheets as part of their operations may need special types of equipment to transport the steel sheets from one location to the other. While the same job can sometimes be done manually by engaging several workmen, the approach may invite serious issues in terms of hazards. Additionally, it will also require the employer to invest additional amounts for the purchase of employee-safety gear. Some sheets will be large and they need to be supported from both the sides during transportation and under such cases, the operations become more efficient if manual labour is replaced by the use of lifting devices.
Plate clamps, plate hooks, and magnets are the three main devices that are commonly used to lift steel sheets. Plate clamps appear in three designs that promote the lifting of steel sheets in vertical, horizontal, and specific positions. Usually two or more plate clamps are used together and they are sometimes complemented by the use of a spr...
