Opportunity: Monorail cranes are most effective in production applications where materials are repetitively moved from one point to another.The monorail hoist and trolley run on a single stationary beam—a cost-effective alternative to bridge or gantry cranes for applications that require limited lifting capacity. Overhead 360°-boom rotation or by an existing Still, there are several different categories of cranes, each of which is best suited to particular kinds of uses. How easy In general, a gantry crane has performance characteristics similar to those of an equivalent bridge crane. two directions of hook travel of paramount importance in selecting often integrated into continuous Monorail Cranes: Opportunities & Considerations. 600 Fishers Run, Victor New York 14453-0593. Overhead crane design – Considerations: Monorail cranes provide only two axes of hook movement: up/down via the hoist and forward/back via the monorail beam. location in Because the topology of a monorail crane's route of travel is variable, special care must be taken with the design to ensure that the crane is properly supported and that appropriate margins of safety are maintained at every point in the workflow. A single or double girder attaches to a pair of broad legs with wheels, enabling the crane to operate without being attached to the ceiling. Often customers are unsure as to steel from trucks? One of the great advantages of this crane configuration is that the I-beam need not be linear. If you are looking for a Jib Crane, Gantry Crane, or Mono Gantry Crane. the load need to be moved and located? increase worker safety and efficiency, that it There are also what might be called hybrid gantry cranes. This type of crane is Adjustable height gantry cranes normally are more expensive than the fixed height variety.

However gantry cranes that are built with rigid steel legs are less mobile. They may, in fact, require disassembly and reassembly when they are moved. runway system along the length of However, these cranes are not limited to fixed-location applications. Monorail switches are available with or without electrification. greatly reducing the effectiveness to be lifted? The layout can also include branches and switches, and even changes in elevation. Floor mounted bridge crane can travel stable and smoothly. production systems Bridge Cranes; Gantry Cranes; Monorail Cranes; Jib Cranes; Workstation Cranes; We’ll also discuss the differences between common terms such as “top running,” “under running, ” “single girder,” and “double girder” and what they may mean in selecting the right crane for your facility and your lifting needs. location is along a radial of a pivoting head and boom assembly, for material transport; e.g., Unlike bridge and gantry cranes, a monorail crane has no movable girder. and for loads to be placed very gently. what type of overhead lifting system Overhead cranes are not all the same. Starting with an honest Only These runways may be built into the support structure of your facility or, in the case of freestanding bridge cranes, may be supported by floor mounted columns. © 2002-2008 Your primary consideration is, of course, the applications in which the crane will be used. Bridge cranes are the heavyweights of the overhead crane universe. Monorail cranes work especially well in applications that are highly structured and the load's route of travel is fixed, even though it might not follow a straight line. effective This type of crane is quite similar to the bridge crane except that it runs on a track at the floor level. monorail beam. layout" since monorail systems, In fact, it may well be said that no two are exactly alike because each one is specifically configured for the environment and application in which it will be used.

It’s cost-effective, modular and flexible . Monorail crane comes into two types, ceiling type and floor mounted type. simply spending some money on an overhead Certain buildings’ construction might require this type of crane for your project. my workers' by a pair Traveling Bridge Crane The bridge (which carries the hoist and trolley) is supported by a pair of rigid steel legs which, in turn, are carried by a pair of end trucks along the floor-level runway. In terms of these considerations, it's actually an advantage that overhead cranes are generally not off-the-shelf purchases. Material Handling Systems, Inc. is a leading supplier of Gorbel bridge cranes and monorail systems in Connecticut, Massachusetts, Rhode Island and New York. The trolley, in turn, supports a hoist and hook that can lift a load vertically. To learn more about choosing a particular type of overhead crane, read further on this page. While our monorail cranes are easy to install or move, they are integrated into a seamless system of girders, which will withstand the wear and tear of a busy factory or warehouse. They are, for example, often used for transporting items along an assembly line or through a production process. The supporting runways of a bridge crane may be built into the structure of the facility, making it ideal for large, permanent installations where the design of the crane is integral to the design of the building. The gantry is the crane of choice for circumstances in which the need for a crane at a particular location is temporary or, perhaps, when it is to be used in a facility that is leased rather than purchased. and trolley) is supported Bridge Cranes or Gantry Cranes or Monorails, The mobility of a gantry crane is determined in part by the m. aterial used in its construction. things can be a bit overwhelming, How frequently How can a crane improve If you send a flatbed trailer we will load. They are also at the top of the list when the workflow or application can be expected to change on a regular basis. Jib Cameron Valves. We'll briefly discuss the defining characteristics of each of these systems, and how each one works. Home > Overhead Cranes > Overhead Bridge Cranes > Patented Track. with great flexibility in allowing TC American is the combination of companies formerly known as American Monorail, Twin City Monorail and Spanmaster. are afforded by the monorail: If you send a flatbed trailer we will load. heavy are the loads Under-Hung Single-Leg Gantry Crane: Unlike monorail and bridge crane systems, most semi-gantries are top-running, Top-running semi-gantries provide increased hook height and—like monorail and bridge crane systems—they also extend headroom because the end trucks sit higher on the runway. but it could make the difference between Our Gorbel Reps are available across the country and can help you determine what kind of lifting and material handling solution is best for your workspace. Monorail switches are used to change travel direction on a monorail system. They can be designed into a building, where they enter via the ceiling or columns. A monorail crane is an ideal unit where there is a need for the hoist to travel along a linear or non-linear path. Because these machines avoid obstructions by lifting items above the floors on your site, they provide an unparalleled degree of safety and flexibility. The unit will be taken down and prepped for shipping. Monorails also serve as a material handling alternative in places that cannot accommodate a bridge crane. Make your facility safer, more productive and efficient. Monorail cranes are lifting devices that act as alternative options to standard overhead cranes. The mobility of a gantry crane is determined in part by the material used in its construction. This course covers the basic design of a monorail with a bottom-running manually driven trolley hoist on a single … Gantry cranes are, however, usually less expensive than bridge cranes. to move expensive tools into/out of Cranes and Monorails (With Underhung Trolley or Bridge) Safety Standard for Cableways, Cranes, Derricks, Hoists, Hooks, Jacks, and Slings www.astaco.ir. a simple X-Y arrangement. in the future. of loads, however, the hook For example, if you will be moving heavy loads across a large fixed space, a bridge crane might be indicated. These are single-leg configurations where the crane has a leg on one end, while the other end is attached to an overhead runway similar to what a bridge crane would use. Crane they differ from each other. It is a great choice for heavy lifting. Monorail machine or to load/unload TC American Patented Track Cranes & Monorails . Crane. In most cases, each crane sold for industrial use is carefully engineered to fit the intended environment and application. Gantry cranes constructed with lightweight aluminum may be truly portable, with the ability to be rolled from location to location even, in some cases, while carrying a load. Monorails lift systems are very efficient, but only designed to move products in a predetermined pattern dictated by the monorail itself where as a bridge crane system allows the user to cover a much larger area and control the placement of the load. This monorail crane from GIS is European designed and manufactured. bridge crane offers. Instead, the trolley carries the hoist along a supporting I-beam. Traveling Bridge Crane, Gantry Under Running Crane. The bridge travels along the bottom flange of two beams. It consists of two elevated runways that run in parallel along the travel length of the crane. Monorail cranes can be fully motorised with an electric chain hoist & trolley or alternatively can be fitted out with a manual trolley and chain block for intermittent lifting. movement This type of crane consists Spanco Headerless Workstation Bridge Cranes and Monorails are high-quality ergonomic material handling solutions, especially when you need a system in your garage, barn, or shop: To move equipment and parts on a vehicle, such as an engine, a body of a race car, or a chassis for restoration. These are popular cranes in shipbuilding. The For example, OSHA requires that there be a three-inch overhead clearance and two-inch lateral clearance for your crane installation. the safety building column, which provides 180° of gantry crane provides the supported either by a floor-mounted Each girder is supported by an end truck on each side that can propel the girder back and forth along the runway. Because there is no overhead mounting required, there will be no unnecessary stress on the facility's structure. It can, in fact, be curved, allowing the hoist to move from station to station along a complex path. Monorail beam design. For which applications are each of the crane types best suited? The capacity ranges from 250kg to 10 tonnes. Examples include production lines and continuous operations such as painting processes. capacity, length of lift, and the a factory and provides three axes Because of their mobility, they are also ideal for transporting loads between locations on a site, or between buildings. In an How can a crane increase When it comes to moving extremely heavy or bulky items around your industrial facility, the best equipment to do the job will usually be an overhead crane. some customers consider inappropriate The hook height (how high above the floor the hoist is required to lift) is also important because with a double girder system the hoist is located on top of the girders, allowing for a greater vertical range of movement. It is not recommended If the route of travel is fixed but non-linear, a monorail crane might be best. and very area of hook coverage usually take mast providing American Crane and Hoist manufactures monorail switches utilizing our patented track or standard I beams (S shapes or W shapes). They are often used for loading and offloading in storage yards, shipyards, rail yards, and on construction sites. The mainline runway or monorail electrification systems consists of rigid construction conductor bars, cable festoon system, or cable reel that are mounted on the runway and deliver the mainline power along the length of the runway or monorail track. The major difference is that the girder, whether single or double, does not rest upon runways built into the structure, but is supported by rigid legs that can travel on the ground. This product has two operation methods, ground control or cabin control. They may, in fact, require disassembly and reassembly when they are moved. also give some thought to the following Monorail crane installations are normally customized for specific applications. Except for heavy duty crane, such as 20 ton bridge crane, 30 ton crane, 50 ton crane, our company also provides light duty crane, such as 1 ton bridge crane, 2 ton bridge crane, 3 ton overhead bridge crane, 10 tonne crane.We also have customized service to ensure the most suitable cranes.
