Product Description:

Brief Description:

Tower crane 4808 is used to lift building material such as concrete, steel bars vertically and horizonally.

All tower cranes consist of the same basic parts:

1. The base is bolted to a large concrete pad that supports the crane.

2. The base connects to the mast (or tower), which gives the tower crane its height.

3. Attached to the top of the mast is the slewing unit (large ring-gear and motor) that allows the

crane to rotate.

4. Attached to the slewing unit is the jib (or boom), the machinery arm, the counterweights

 and, the Operators cabin

Q:are crane fly poisonous?
No daddy long legs are real because when I got home from last night and I also saw 5 crane flies on my door so daddy long are at are real after all and also crane flies aren't poisonous.
Q:Summary on The Open Boat by Stephen Crane?
amazed that I found this topic already answered! It is like you read my thoughts!
Q:In the case of tower crane operation, the operation should be stopped
In case of six or more gales, heavy rain, heavy fog, heavy snow or tower crane, you should stop working
Q:Neck-craning & neck-straining?
it will can be let you feel well.
Q:Best structural crane design?
Not enough information because a crane can be many shapes and have various forms of anchoring or counterbalancing the load. If you are not allowed to anchor to a base and can't use weight to counter the load (if all balsa) then you have to create legs and lift the load between them - Basically the design will need to be triangles in truss to take the compression and prevent twisting and a long upper piece in tension to act like the cable you don't have. I would make two legs that are each 3 sided trusses that meet at the top and have a single rod across the bottom to keep them from spreading. Then I would make a longish beam with flat triangles for stiffness and use a few uprights to position the tension rod. Hang the weight on one end and push down on the other so it pivots on the short legs.
Q:What is the allowable range of vertical deviation for tower cranes?
The verticality deviation range of ZOOMLION tower crane is allowed within 4/1000.
Q:How does a climbing or tower crane work?
They add extra stages from the bottom. A tower crane is erected from a boom assembly, first and second tower sections of different cross section, and a base in a sequence of steps in which the boom assembly is mounted on a hollow climbing section dimensioned to be received in each of the larger second tower sections and defining a cavity dimensioned to receive each of the first tower sections. One of the latter is secured on a base in upright position, and the upright section is received in the cavity of the climbing section which is then raised relative to the first section and enveloped by one of the second sections. The enveloping section is secured to the base and the raised climbing section for supporting the climbing section whereupon the first tower section may be released from the base, raised, and secured to the second tower section. The climbing section may then be raised relative to the first tower section to permit the installation of another second section, and the procedure repeated, until all second or larger tower sections are superimposed on each other, the one first section being ultimately attached to the topmost second section. When the climbing section is raised relative to the attached first section, another first section may be superimposed on the one first section and the procedure repeated until the slimmer portion of the tower is assembled from superimposed first sections. Ultimately, the boom assembly is attached to the topmost first tower section, and the climbing section may be removed or stored for further use on the wider, lower tower portion.
Q:What are the main technical parameters of a tower crane?
Generally speaking, the main parameters of the tower crane are:Maximum amplitude unit MMaximum lifting height, unit MMaximum lifting torque unit KN.mMaximum lifting speed unit m/minMaximum lifting unit tRotational speed unit r/minVariable speed unit m/min or o/minWalking speed per unit m/minMotor power unit w......Please refer to the product manual.
Q:Are there any white crane Kung fu centers in or near Yonkers ny?
Google it and see.
Q:why are whooping cranes on the endangered species list?
Over-hunting, habitat conversion and human disturbance were the main causes of the decline. Currently, the most significant known cause of death or injury to fledglings is collision with powerlines7. Birds are depredated by Golden Eagle Aquila chrysaetos, especially on migration3, and drought is deteriorating breeding habitat9. Pollution, boat traffic, wave erosion and dredging threaten the Texan wintering grounds9. Aransas NWR can only support a maximum of 150 birds through the winter, forcing remaining birds to use disturbed and suboptimal habitat - this is considered to have stabilised the growth of the wild population in recent years13. The long-term effects of genetic drift after a severe population bottleneck4 are unknown. There are currently concerns about oil spills and about river flows in Aransas National Wildlife Refuge14, and the spread of West Nile virus may pose a threat to the species15.
