Self-erecting crane

Self-erecting Cranes, generally a type of tower crane, also called self-assembling or "Kangaroo" cranes, lift themselves off the ground using jacks, allowing the next section of the tower to be inserted at ground level or lifted into place by the partially erected

Bridge Crane

and backward. Both single and double girder overhead traveling bridge crane designs allow very precise hook positioning and gentle load placement. Double girder cranes typically provide better hook height, but single girder cranes offer other adVantages depending on your application.

Truck

A truck, also named lorry, is a motor vehicle designed to transport cargo. Trucks vary greatly in size, power and configuration, with the smallest being mechanically similar to an automobile. Commercial trucks can be very large and powerful, and may be configured to mount specialized equipment, such as in the case of fire trucks and concrete mixers and suction excavators. Modern trucks are powered by either gasoline or diesel engines, with diesel dominant in commercial applications.

All Terrain Crane

As the name suggests, all-terrain cranes can manoeuvre through rough terrain as well as public roads with ease. These cranes are technologically the most adVanced of all the mobile cranes. They come in both lattice-type and telescopic-type boom options. All terrain cranes that are ideal for both on and off-road construction and industrial projects. Regardless of the location, temperature or climate, all-terrain

Crawler Crane

and can be quickly relocated at different locations on a project site. However, for shifting to another project site, these cranes require a truck or a trailer. The inability to be shifted from one site to another on its own is one of the main disadVantages of the crawler crane. Nevertheless, these cranes can work in difficult ground conditions. The cranes normally have lattice boom but are also available with the telescopic boom option.

Tower Crane

of huge buildings. They are a common fixture at any major construction site. They are used to lift steel, concrete, large tools like acetylene torches and generators, and a wide variety of other building materials. Tower cranes have distinct adVantages over conventional lattice boom crawlers or truck cranes because the boom or jib looms high above the work site. The tower cranes jib can place its load anywhere within the radius of operation without interfering with the structure over which

Truck Concrete Pumps

Truck mounted concrete pumps are those engineering products that are used to supply concrete to places which are difficult to reach by other heavy machines. Concrete Pumping Equipment required : concrete pump, heavy-duty pipe, hose and other accessories. Concrete pumps can be mounted on any type of diesel powered trucks. When pressure is applied to a column of fresh concrete by the concrete pump it forces the concrete through a lubricated pipe.

FAQ About Van Crane

In these cases manufacturers instruction manuals must always be available and followed. This is particularly releVant in the case of tower cranes where erection and dismantling must be carried out strictly in accordance with the manufacturers instructions. The erection of jibs on cranes, especially mobile cranes, must follow the sequence described in

  • Testing and Examination of Cranes and Certain Lifting Appliances

  • Coupled Cranes

    • An accurate calculation must also be made to determine the share of the load which is to be taken by each crane. This Regulation is quite specific in the requirements which must be adopted when this type of operation takes place i.e. AdVance planning Supervision by a competent person The use of cranes of similar design and equal capacity Each share of a load taken by a crane must not exceed 75% of the safe working load of that crane If an operation requires the use of

  • Raw Materials of manufacture cranes

    • (HSLA) steels are used. HSLA steels contain relatively low levels of carbon, typically about 0.05%. They also contain a small amount of one or more other elements that add strength. These elements include chromium, nickel, molybdenum, Vanadium, titanium, and niobium. Besides being strong, HSLA steels are resistant to atmospheric corrosion and are better suited to welding than carbon steels. Depending on the exact design of the crane, a wide variety of other materials may be

Thus, all climbing work is accomplished from the ground. AdVantages of push-jack systems are that they are rudimentary and thus easily understood and repaired, provide positive load guidance, and can be worked from the ground. Disadvantages are that they are slow, lack means for lateral adjustment, and the

These limitations not only weigh on the operation but also need to be considered when the front-end attach ment is to be stowed during nonworking hours or the crane is to be secured in adVance of a storm. Interference is sometimes caused by a secondary element that might easily be missed unless the planner takes a second look. A cab, slack cable, or transition piece might easily be overlooked. The clearance dimensions of projecting
