questions about jib cranes/swing jibs/pillar jibs/slew boom
Cranes are probably the UK largest independent jib crane
suppliers and installers. Most months we sell and or install
between 10 and 14 jib cranes.
customers have questions they need answering before they
can specify or place an order for a swing jib crane. Even
though a brand new pillar jib cranes including an electric
chain hoist can start from under £1500.00 the pillar
crane you purchase needs to be right and meet your needs
before ordering a jib crane please take a moment to read
about the questions we get most frequently asked. If you
need to call us our jib crane advisers; Chloe (the clever
one), Laurie (a bit ditsy), Tristan or Alan will be only
too happy to help.
Please remember jib cranes can lift large heavy weights
high into the air and overhead; if done incorrectly it can
be a dangerous piece of equipment. At AG Cranes Ltd we want
you and your employees to be safe and productive.
quote you a swing arm jib crane we will need to know:
The SWL, or safe working load you need to lift. Example
The height you need to underside of the jib arm or lift
height from the floor. Example 2.5 meters.
The arm length needed to swing the load. Example
The height of any overhead obstructions: Example
roof lights at 4.2 meters.
our team of fully trained experts have the information we
will be able to give you a quotation based on what your
AG CRANES quotation will feature the jibs SWL, the overall
height of the jib, the floor to underside of the jib crane,
the hook at it's highest point and the jib cranes arm length.
Factory Floor To Support the Jib Crane. Will it take it......
customers ask us about the floor depth required to support
the new jib crane. You must remember your jib crane supplier
cannot guarantee your factory's floor depth or suitability.
As an example of bolt embedment depth an M20 bolt will need
170mm, while an M24 requires 210mm.
installing a new or used swing jib crane you have four choices
when it comes to your workshop floor:
1: Fit an extra
large or oversized base plate the most common and popular
choice. For our new Donati
jibs we can supply an extra
large base plate to fasten to the factory floor. The
large jib base bolts to the floor with 8 or 12 bolts. The
jib cranes pillar is then bolted to it. The oversized base
plate comes pre-drilled to accept the jib pillar/column.
on the oversize jib base.
Option 2: Dig a pit and fill with it concrete,
leave it to cure for a couple of weeks, and then fit the
jib on top of the new floor base. This is popular with used
jib cranes or other makes other than Donati.
3: If digging a large pit/base for our new Donati
jib cranes we can supply you a set of ground
anchors, or "J bolts". (See below), this is
by far the safest option for new pillar cranes. The ground
anchors, or large "J bolts" sink into the factory
floor base you have prepared. Before filling the base with
concrete of the required grade, you need to insert the ground
anchors with the jib base template and leave the tops of
them around 100mm proud of the hole. Once it has gone off
the jib crane lands straight on to the anchors and is tightened
up. This usually takes two or three weeks to go off. Once
it has gone off we can then land the jibs column onto the
protruding ground anchors before commission and testing
takes place. Ground
Anchors: More details.
Option 4: Do nothing and hope the
floor will take the load and over turning
moments imposed when installed and tested! Please
remember the floor is always the clients responsibility.
All that we ask is if it fails the proof load test is that
you pay us! Seriously at 500kg SWL or above we will always
"ask how deep is your factory floor before installation."
arrival if the floor depth is not the correct depth the
engineers will consult with you and our office. If you wish
them to carry on you will be asked to sign the install engineers
site sheet taking responsibility.
jib cranes, testing, certifying, installation warranty etc.
companies in the current climate want to save money. At
AG Cranes Limited we are often asked to supply used
jib cranes or used jib cranes with new hoists as a compromise.
We will still offer a warranty on used jib cranes, as well
as a test certificate if we carry out the installation.
If you want a new electric chain hoist on the used
jib crane that you purchase to help to keep the costs
down we can offer this and are only too happy to quote both
options. Though cheaper used jib cranes "are what they
are" as we often say in terms of dimensions. With new
jib crane we can make them to your exact dimensions.
cannot offer ground anchors or extra
large base plates pre-drilled for our used jib cranes;
unless we know what make it is. Luckily however when buying
a used jib crane it will nearly always have a base plate
large enough already on it, as it will have been used elsewhere
There will always be differences between the depth of two
if you are in doubt you should consult a local civil engineer.
