A scissor lift is a type of aerial work platform that can usually only move vertically, usually with common working height ranging from 6 meter to 18 meter. The mechanism to achieve this is the use of linked, folding supports in a criss-cross X pattern, known as a pantograph (or scissor mechanism). The upward motion is achieved by the application of pressure to the outside of the lowest set of supports, elongating the crossing pattern, and propelling the work platform vertically. The platform may also have an extending deck to allow closer access to the work area, because of the inherent limits of vertical-only movement.
These units are able to drive themselves (on wheels or tracks) around a site (they usually require to be transported to a site, for reasons of safety and economy). In some instances, these units will be able to move whilst the job is in progress, although this is not possible on units which require secure outriggers, and therefore most common on the scissor lift types. The power can be almost any form of standard mechanical drive system, including electric or gasoline powered, or in some cases, a hybrid (especially where it may be used both inside and outside).
The contraction of the scissor action can be hydraulic, pneumatic or mechanical. Depending on the power system employed on the lift, it may require no power to enter “descent” mode, but rather a simple release of hydraulic or pneumatic pressure. This is the main reason that these methods of powering the lifts are preferred, as it allows a fail-safe option of returning the platform to the ground by release of a manual valve.
Apart from the height and width variables, there are a few considerations required when choosing a scissor lift. Electric scissor lifts have smaller tyres and can be charged by a standard power point. These machines usually suit level ground surfaces and have zero or minimal fuel emissions and mostly indoor works. Diesel scissor lifts have larger rough terrain tyres with high ground clearance for uneven outdoor surface conditions. Many machines contain outriggers that can be deployed to stabilise the machine for operation.
What is Boom Lift??
Boom Lift which also commonly knowns as Cherry Picker is a mechanism that able the user to reach or access not only the horizontal height reach but also the vertical outreach with the aids of the mechanism structure. The name of boom lift is coming from the machine outlook which look similar to the cannon boom.
Type of the Boom lift ??
The type of the boom lift can be differentiated by 2 main factors which is the mechanism structure and the power sources of boom lift.
Firstly, we can categories the boom lift mechanism structure by observe the number of booms of the boom lift have. If there are only single boom, this is a Straight boom type boom lift but if there are two boom which normally known as primary boom and secondary boom, therefore this is a articulating boom type boom lift.
Secondly, there are 3 kind of power sources to operate the boom lift, which is Battery operated, Diesel engine operated and also hybrid power operated (a combination of battery operated and also diesel operated). The different of power sources operated are needed due to the different usage and the size of the boom lift. Battery operated boom lift are less sound and air pollution compared to the diesel operated boom lift therefore battery operated boom lift are suitable to use in a place that required less sound and air pollution but there are a limitation to battery operated boom lift too as the battery operated boom lift are not able to provide sufficient power to running the large boom lift as the large boom lift are too heavy and required more power to operated.
Range of the Boom lift able to reach ??
Battery Operated Boom Lift
Vertical Working Height: From 12 meter Working Height to 20 meter Working Height
Horizontal Working Reach: From 6.7 meter Working Reach to 14.1 meter Working Reach
Diesel Operated Boom Lift
Vertical Working Height: From 15 meter Working Height to 58 meter Working Height
Horizontal Working Reach: From 7.6 meter Working Reach to 24.3 meter Working Reach
Do Boom lift Safe to be use?
The main safety concept that support for boom lift are using counterweight concept. The counterweight of a boom lift may take up to 60 to 70% of the boom lift total weight and always located opposition to the platform control. Therefore, Boom lift are safe to be use as long as the operator follow the operation manual accordingly and do not load the weight more than restricted.
A personal lift, also known as vertical lift or vertical mast lifts. Usually can only be accessed and operate by a single individual, hence the name personal lift. Working height is commonly ranging from 8 meter to 14 meter.
This type of lift usually eliminate the needs for scaffolding or ladders, personal lift allows you to get closer to your overhead work and maintenance applications in safe manner and sometimes quicker. Due to the smaller and compact design of the machines, you’ll be able to fit through standard
doorways, manoeuvre your way through narrow aisles and go more places compared to the bigger lifts like scissor lift or boom lift. Personal lift are great for general repair work, routine maintenance, managing inventory and even hanging holiday decorations.
What is Spider Lift??
Spider lift have remarkably similar usage and functionality to boom lift and always consider as a variation of boom lift. The main purpose of spider lift is to provide extra flexibility and versatility that unable to access by the traditional boom lift as spider lift is lighter and narrow in size compare to
traditional boom lift. The name of spider lift is come after the outlook of the machine as the machine must come with 4 outrigger which look remarkably like spider species.
Spider Lift Vs Traditional Boom Lift
In order to compare the advantage of the spider lift over the traditional boom lift , I will use JLG M600AJ
(Traditional Boom Lift ) and JLG X20-J Plus (Spider Lift ) to do the comparison due to both of the machine
are provided the same vertical working height and both are battery operated machine.
From Result above, JLG X20-J Plus was consisted only 35% and 33% of the JLG M600AJ Weight and
Machine Width respectively which will provide JLG X20-J Plus a very huge advantage to operate in more
challenging and compact work situation. Last but not least , the JLG X20-J Plus using the track as a
maneuver methods allow it to travel better on non-even / Wet soil / sand surface compare to traditional
boom lift too.
Range of the Spider lift
Vertical Working Height: From 20 meter Working Height to 42 meter Working Height
Horizontal Working Reach: From 9.7 meter Working Reach to 16.1 meter Working Reach Respectively
Do Spider lift Safe to be use?
In Malaysia rental market, renting spider lift usually will come along with a specialist operator to operate
the spider lift due to the complexity of the spider lift. Therefore, the risk of using the spider lift are
minimized. However, user of spider lift are also advised to double check the outrigger are well
positioned and all outrigger sensor are well functioned before raising the platform to access the working
A telescopic handler, also called a telehandler, teleporter, reach forklift or boom lift, is a machine widely used in agriculture and industry. It is somewhat like a forklift but has a boom (Telescopic Cylinder), making it more a crane than a forklift, with the increased versatility of a single telescopic or articulating boom that can extend forwards and upwards from the vehicle. On the end of the boom the operator can fit one of several attachments, such as a bucket, pallet forks, muck grab, or winch. Telehandlers are sometimes called cherry pickers in North America, as that name can refer to any truck or heavy equipment that has such a boom.
