The Technology is there to make lifting easy.
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 Armand 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. Check at Millsom
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 theJumboSprint. 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.
