Lyftman LR-System - lightweight crane systems and jib cranes
TAWI manufactures Lyftman LR-Systems consisting of monorail, single girder cranes both in steel and aluminum, twin girder cranes, curves, low built systems and floor mounted constructions.
Our cranes and jibs are manufactured based on the Lyftman LR-System profiles. The reliable and cost effective steel profile LR120/170. It is produced from cold rolled, single piece high strength steel. The self-adjusting joint concept is designed to simplify installation. Our automatic powder coating line ensures high quality resistance to corrosion and long lifespan. With four basic track sizes and self-adjusting joint concept an optimized combination is always guaranteed. Offers a span up to 8 meters between supports for ceiling structures with infrequent support points.
Lyftman manual jib cranes are available in four basic versions for installation on a wall or column to handle goods up to 125 kg.
A majority of the models are available with jib arm in aluminum to offer the least amount of friction, achieving smooth operation. These jibs can be installed to a wall or column and are suitable for lightweight goods handling. The radius of action is available between 180-270 degrees. Arm length is available up to 6 m.
The monorail system is a cost effective choice with all the advantages of the Lyftman LR-System. The monorail serves a working area along a straight line when there is no demand for sideways transportation. It is therefore ideal choice for lifting and moving loads along a fixed line. The modular design of the LR-System allows for extensions and additions to create an x-y system anytime. This monorail is used to lift metal parts in the electronics and automotive industry. The modular design makes it possible to extend to create an x-y system anytime.
The single girder crane system is the most popular type of industrial installation. This system covers a rectangular (x-y) working area. Multiple girders are usually used when the system covers more than one working station. With multiple girders the complete system can either be dimensioned to handle the heaviest weight or buffers/stops can be used to separate the working areas. The basic is overhead x-y crane system. There are many reasons why this solution is very popular, competitive pricing, fast deliveries, high quality and easy installation are some. A wide range of suspension solutions are also available.
Boxes of eggs are palletized using a vacuum lifter in a crane system with both girder and bridge in aluminum profile. The low weight of the system is a great advantage for the operator who moves the crane bridge manually. This means that the operator by hand pushes the vacuum lifter in the aluminum profile over head. The design and the low weight of the single girder crane system make it possible to move these boxes quickly and carefully.
A twin girder crane system is the choice for heavier loads. The twin girders are welded together in a triangular construction to stabilize operation when handling loads up to 1500 kg. It is very common that the twin girder crane system is optionally equipped with motorized trolleys to automate the traveling motion of the girder and/or hoist. To obtain more options the two-speed motorized trolleys can be equipped with a frequency converter. This also increases the performance of your twin girder crane system. When handling loads up to 1500 kg a safe and smooth operation is easy to achieve with Lyftman LR-Systems.
Curves are a natural step towards the optimal overhead system. With 45 degree angular modules in combination with the variety of profiles and the flexible range of suspensions we can offer an optimal system, every time. Curves are used to follow a production line through the manufacturing process to final packing stations. Curves create more flexibility to your overhead system where single girder cranes (x-y system) are out of the questions due to obstructions in the ceiling structure. An example could be a ventilation system above a working station that makes it impossible to install a girder crane in a gantry. Monorail in combination with curves is the solution! With our 45 degree modules you can create an overhead system that follows your production all the way from primary produce to packing stations.
The Lyftman LR-system is a versatile system that can be suspended from freestanding constructions, as shown in the picture. Floor mounted, freestanding cranes are a versatile solution to conventional I-beam cranes. A free-standing construction is flexible and easy to install and maintain. This is an example of a floor mounted system in the packaging division of an electronics manufacturer. A good solution when it is not possible to suspend a crane system on the ceiling.
By combining steel and aluminum profiles we create an optimized system. The steel profiles are best used for fixed installations and the aluminum profiles for operational, moving parts. This ”miniature” combined crane system is installed in a warehouse construction making that the operator no longer has to manually reach in and lift the heavy boxes of printed material. On the picture, orders for printed material are lifted off the pallets and loaded onto the order pallet. A triple profile girder system (three tracks in the gantry instead of two) to obtain extra wide bridge span is also available.
Lyftman low built crane system is a compact solution, designed to allow a maximum possible vertical hook stroke in areas with low headroom. The special low built construction holds the girder and gantry at the same level, thus saving place. The warehouse on this picture has low headroom and the Lyftman low built crane system is an excellent choice. The low built crane bridge construction is shown in the left side of the picture. This installation consists of two bridges in an aluminum runway.
TAWI vacuum lifters VacuEasylift, VacuMove and VacuCobra (on the picture) are particularly suitable in combination with a jib arm in aluminum. With a correct choice of jib crane it is possible to work very quickly with a minimum of manual force. A manually operated jib is most effective when the outer part (2/3) of the arm is used. The total length of the arm should not exceed what is needed to cover the working area. It is very important that the manual lifts are done with good ergonomics, therefore the installation and use of the tool should be planed with awareness. One way is by using the outer part of the arm instead of the inner part as mentioned above.
Sacks are often lifted in the food and plastic industries. Most commonly the operators lift and move sacks from pallet and into the production line, manually. This is extremely strenuous work in the long run, with potentially harmful turning motions often handled in a small area. A tube lifter in a jib crane, column- or wall mounted, is a perfect solution for this type of problem. A low built jib builds only 300 mm at the point of installation. We manufacture custom made columns for low headroom areas, available for loads up to 40 kg. A knuckle-jib is an alternative to improve operational space in small areas.
A jib crane is the perfect solution for workplaces that requires repetitive, stationary lifting. If there is no wall or column construction available for the installation, the column can be delivered from us. TAWI can provide a wide range of jib cranes such as articulating arms, lightweight ergonomic arms, ceiling or wall mounted and free standing.
Our complete range of jib cranes and custom made are available to solve your manual lifting problem in all type of working situation. Ergonomic lifting of heavy stones (shown in the picture) by one person is possible with a vacuum lifter in combination with a Lyftman jib crane.
