If you are seeing a pattern of growth, you may want to upgrade the design of your crane, so that it can handle projected increases in activity. While it may be more crane than what you need at the moment, you want one that will keep pace as demand increases.
It can be tempting to try to rent a crane or rig something that you hope will work to move something that's heavy, but this opens the door to a lot of possible safety issues. When in doubt, the better choice is to trust your heavy moving jobs to crane and hoisting professionals.
The United States government sets specific regulations through the Occupational Safety and Health Administration that limit the weight that a specific crane is allowed to lift. The Crane Manufacturers Association of America sets its own safety standards which exceed those required by the government.
Did you know that all tower cranes contain the same basic parts? Some of these include the base, which is bolted to a large concrete pad that supports the crane and the mast (or tower), which gives the tower crane its height.
Cranes help move a lot of things, including people. In the 1950s, billionaire Dennis Washington started his journey toward wealth by leaving for Alaska and working as a crane operator, which helped launch his career in construction.
When dredging of waterways is needed, cranes with dragline and clamshell capabilities are the best equipment combination available. Not only can they remove waste materials to any desired depth, but they also have the versatility to deposit the dredging in designated areas.
Articulated jib cranes are recommend for sites that need a crane that can reach through doorways or around barriers or obstacles. As the name implies, the arm of the crane is jointed, allowing it to bend.
Pneumatic air hoists offer many advantages to their electric counterparts. Here, the vane or piston operated motors include variable speed control, and since there is no electrical circuitry, they are tolerant of unfriendly working conditions with high levels of dust, heat, and humidity.
Was the Greek Parthenon built with the aid of crane technology? If you guessed yes, you're probably right. The ancient Greeks are widely credited with building the first construction crane, and many experts believe cranes were used to build the Parthenon.
With tower cranes, the long horizontal jib or working arm is the portion of the crane that carries the load. In most cases, there is a trolley that runs back and forth along the jib to move the load in and out from the crane’s center.
An overhead traveling crane is a kind of bridge crane in which the rails are located high above the ground. Usually supported from the ceiling of a building, an overhead traveling crane has the advantage of causing no obstruction in the work area.
It takes a crane to lift a crane. When engineers restored the last surviving example of an 1833 wooden crane, they used a 65 tonne mobile crane to move the 30-foot oak jib and 20-foot main frame into place.
Did you know that wire rope is preferable to chain slings when it comes to hoisting and rigging mechanisms? This is because the failure of a single link of a chain can end up resulting in the failure of the entire mechanism, whereas wire rope is much more reliable.
The platform of a mobile crane can be designed in one of several different ways, depending on application. It can be equipped with traditional wheels, wheels that have been designed for railroad tracks, or a caterpillar track for navigating unpaved and uneven surfaces.
Did you know that crane manufactures have a professional association that represents their industry? The Crane Manufacturers Association of America has been operating under the name since 1955. Its members are based in the United States, Canada, and Mexico.
The first cranes were animal powered. Care to guess what animal was often pressed into service as the muscle behind early crane technology? If you guess the donkey, you're right.
Over the years, cranes have evolved themselves into different types. Some of them are deck crane, jib crane, gantry crane, telescopic crane and level luffing crane. Every type of crane has its own use and specialty.
Did you know that many monolithic structures like the Greek Parthenon and the Acropolis, as well as the Egyptian pyramids, may have used cranes in their construction? Historians believe that cranes have existed for more than 2,000 years and may have helped construct some of the world’s most famous structures.
There are three ways by which cranes are able to lift loads. Some cranes use a lever setup to gain mechanical advantage, others use pulleys to lift loads, and still others use a hydraulic cylinder, either directly or in the powering of a lever or pulley.
A hoist, as defined by Britannica, is a "mechanical device used primarily for raising and lowering heavy loads but occasionally for moving objects horizontally. It usually consists of a block and tackle."
There are a number of parts to a tower crane, the crane often used in multi-story construction projects. Can you guess some of them? If you guessed the: base, cab, tower, slewing unit, boom, machinery arm and counterweights, you're right.
Before beginning a project, conduct a site assessment to ensure that no underground installations will be compromised. These include electrical vaults, piping, tanks, and conduit banks. We will provide qualified personnel to conduct proper testing and analysis.
Overhead gantry cranes for industrial applications can be installed as stationary tools, or they can be freestanding and mobile. Their configuration allows a greater reach, and, subsequently, can be adapted to more tasks.
If you require that loads land on blocking, the blocking must be sturdy and sufficient so as to prevent damage to the slings, and stable enough to prevent tipping or roll-off during landing, unhooking, and unslinging.
