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...
