Overhead cranes are still an important piece of equipment needed for lifting loads of all kinds. There are a number of different kinds of overhead cranes that can be used depending on what they are needed for.
Slewing or Jib overhead crane
This is the classic “crane” that is still common around such places as sea ports. The largest overhead cranes on offer can lift loads up to 5000kg and have a slewing (turning) radius of 8 metres.
There are two main types of overhead cranes available, Slewing Arm and Arm Support.
Slewing Arm overhead cranes are either top braced, or low head room.
A top braced overhead crane can be used with vacuum lifting equipment, such as Jumbo vacuum tube lifters. These are designed to lift weights up to 500kg.
A low head room overhead crane uses an “I” beam construction and it is designed to operate in a restricted space. These have a lifting capacity of up to 5000kg.
The Arm Support Slewing Arm over head crane comes in two varieties. They are either free standing or column mounted.
With the free standing jib crane the slewing arm length can be specified by the customer. The supporting column is then bolted into a concrete base. If the jib crane is expected to lift heavy loads, then either the supporting column can be fixed to the concrete using special anchors, which have been chemically set, or new concrete footings will be used along with bolts, that are set in the concrete.

A column mounted jib crane. This is where a pre-existing column or structure can be used to support and secure a jib arm crane. This cuts out the need for setting up a column for a jib arm. Various attachments can be used. This will also save the cost of fixing a new column.
Uses of a venturi vacuum pump
Technically, a venturi vacuum occurs when air is forced through a compressed space at high volumes. The vacuum occurs at the constricted point. One application of this is with nozzles. The Basic Ejector SEG is a nozzle system which applies the “venturi” effect. This makes this a suction device or a venturi vacuum pump.
There are a number of applications for this device. This can be applied to sheet metal work and the automotive industry. It can also be used in woodwork production, packaging and the food industry.
Because of its relative small size, this small suction device can be used in industrial robotics, manipulators, and feeder systems, along with many other uses.
There are no moving parts. As a consequence there will be no wear or need for maintenance. The suction or vacuum produced by this system is very efficient and a fairly minimal input of compressed air is needed to produce this outcome.
The body is made from aluminum which results in a low weight for this unit.
The Jumbo Modular system is a vacuum lifting device that uses vacuum generators to create a vacuum and suction effect, with which to lift a range of items. There are two different Jumbo systems; the JumboErgo and the JumboSprint. Both use the same basic side-channel blower to produce the vacuum.
This results in a range of versatile and easy to use lifting devices.
Perhaps, you may begin by saying that there is no machinery where a screw is not used! Yes, it is a fact that machines will have screws in some form or the other. There was a time when screws in Bogota were only made of metal. However, now you find screws made of plastic, fiberglass and various other products. Check out tornillos en bogota
The architecture of a screw:
Screws are regarded as a type of fastener with a helical or smooth edge. Normally, screws are designed to align with threads of appropriate size. The threads can be in the form of nuts or any object with internal thread. The screws are technically known as male thread and the thread inside the nut or the internal thread is called as female thread.
Importance of head on the screw:
The screws in Bogota will invariably have a head which is much bigger in size than the body. This is done to help to effectively fasten the screw into the thread. Of course, in few cases, screws will have smaller heads, and such screws are known as anchor bolts.
Type of rotation:
The screws are always turned in clockwise direction to tighten and in the anticlockwise direction to loosen from the thread. However, in some cases where there is greater rotation, then the screws in Bogota will be turned anticlockwise for tightening and clockwise for loosening from the thread. The best examples of screws are those used in the blades of a mixer grinder.
The screws are available in different designs and sizes. A brief discussion on these is made here:
· Screws are available in different types like a lag screw which are used in woodworks. There is also the mirror screw having a flat head with a hole in the middle and the hole is covered by a cover with appropriate plating. This type of screw is used in the mirror. The other popular varieties of screws are hex screws. This type of screw is generally called as hex cap screw because it has hexagonal head, and it is significantly bigger than hex bolts.
· Other important types of the screws that are common in most of the machines include the structural bolts. This type of screw will have a thread up to certain portion of the body of the screw. The unthreaded portion of the body also called as shank length is intended to provide better grip to the body of the machine where it is used.
· Yet another important type of screw used in most of the machineries includes the threaded rods which are also called as ‘studs’. Perhaps, this rod or ‘studs’ can be called as an exception to the concept of screw. This is because the ‘studs’ will have thread but it will not have that large body head. The studs are available in two types namely full bodied studs and the other type called as the undercut studs. As the very name suggests, full bodied studs will have threads throughout the length of the ‘studs’. On the other hand the undercut ‘studs’ will have thread up to a certain level; may be up to half the rod or 1/3rd the length of the rod and so on. Check out Tornirap
Directly related to its application:
Use of the various types of screws always depends on the type of its application. They are available in different sizes with varying dimensions of thread.

Handling smooth surface materials could have been a tiresome task were it not for the Sack vacuum lifters. Some cartons are very slippery yet they are supposed to be moved from one point to another or from the ground to a certain height. Lifting them manually is not only a tiresome act, but also it is a risk to the products that are contained inside it. Things like concrete slabs, pipes, plastic laminates and cement bags need to be handled with care for them to remain safe. Sack vacuum lifters work by utilizing suction pads for firm attachment to the load and maintaining the pressure until the load reaches the required place.
Types of vacuum lifter.
The vacuum tube filter could be made in two forms depending on the customer’s choice, and the purpose intended for. One is the vacuum lifting tubes that are comprised of vacuum tube with lifting pads that attach to the load. These are meant for attachment and lifting of the load. This provides convenience in load lifting since it does not require supplementation with anything for it to be efficient. The other type is the vacuum lifting attachment. These are required to be attached to other machines like the pulleys. The core function of this type is to offer gripping and attachment of the loads so that they can be uplifted from one point to another.
How to make the lifter efficient.
To reduce accidents and emergencies during the use of these machines, manufacturers have established safety standards that every manufacturer should meet. Engineers have now invented the sacking and splitting vacuum lifters that are more precise and accurate during load handling. They have the ability to open and split the sacks without compromising the sanction power of the machines. Vacuum lifting equipment Australia agencies sell, does not involve the use of extra manpower since it has a small fingertip point that is used to control it.
Advantages of the sack vacuum lifters.
The benefits of these lifters would only be availed when they are made from high quality materials. A compelling design and proper incorporation of the features should be superiorly done to ensure the lifter remains intact even after handling heavy weights. High strength of the suction pads would always guarantee the safety of the loads. Once a pad attaches to the load, it should be able to maintain the pressure until the load is placed where it is needed. For marked efficiency and warrant of safety, a pre-supply test is normally paramount to verify the quality of the lifter.
Hoisting Equipment is something that to a higher extent determines the efficiency of the lifter. To avoid easy accidents, these hoisting machines should be designed to overcome overload effects. They should be made heavy duty from the higher strength raw materials ever. They are supposed to be ergonomic and user-friendly for them to be efficient and perfect.
Chain hoist improves the functionality of the whole system. Making it of superior quality and perfect design would improve the reliability of the whole system. The reliability and durability of the vacuum lifters depend greatly on how these are constructed and how the various parts are fixed. The use of high quality raw materials and using knowledge to construct it makes the lifter reliable.
