Chain hoists or electric chain hoists are commonplace lifting equipment in the maintenance industry.

Maintenance is probably the most critical element of the production process.

However, it is often invisible and overlooked.

Because of this, it is not considered the star of the manufacturing process.

According to most quality gurus, production systems cannot be efficient and effective without a robust maintenance system supporting the production machineries.

Hence, Rotomatik Singapore working closely with the customer advised that a reliable maintenance system is a pre-requisite in the overall performance of production machinery.

To cut maintenance downtime, five units of chain blocks ranging from 1 tonne to 5 tonne are setup as providing the lifting role.

All these chain blocks are installed on a monorail beam measuring 1.8 metres with a 2-metre lifting height hovering over a group of machineries.

Chain blocks are operated manually and are routinely checked to ensure they are serviceable and readily available to do the task as designed.

Another key function of a reliable maintenance system is engineering logistics.

Therefore, the customer is assured that Rotomatik Singapore stands ready to deliver servicing and parts.

KBK cranes are a flexible and configurable system that can be patterned just like a LEGO system.

KBK system is basically made up of tracks and other related track accessories. Two vital characteristics of the system are inbuilt into the way the tracks are designed and fabricated: Its internal running surface are specially angled such that the manipulators are always running very smoothly along the entire track; it is specifically sloped such that it forces the manipulator to be perpetually perpendicular to the track.

A multi-national company was evaluating the kinds of material handling systems to manufacture and process its finished products. In an age of robotisation and automation, the company decided to take a step back and re-look at the working relationship between man and machines.

Hence, a number of material handling system experts were invited to present their systems. Rotomatik Singapore basically clinched the proposal with their innovative KBK solutions coupled with speed and quality of execution.

With a focus on mechanisation, Rotomatik Singapore offered a system comprising a manipulator supported by a KBK crane system. Manipulators capable of handling 160 kg of load and with a lifting height of 2.2 metres are used in the production process.

Flexibility of KBK Overhead Crane

The final entire system is that the manipulators can easily be maneuvered effortlessly and they always in a strict vertical position, a pre-requisite for their function.

A consumer packaged goods company has reviewed its production process.

In land scarce Singapore, even the footprint of production floor has to be optimised.

Due to the limited manufacturing area, a material flow analysis carried out determined that products had to be hoisted to the second floor.

Hence, vertical lifting in contrast to lateral movement ensures a shorter and economic routing and more efficient material flow.

Rotomatik Singapore recommended a 2.2t goods hoist.

Installed in 2019, the goods hoists is fully packed with all the safety hallmarks expected of any Rotomatik designed and manufactured product.

Because of the need for safety, the goods hoist is fitted with the salient features such door sensors, interlocking system and safety catches amongst others.

The heart of the goods hoist system is a true vertical lift Stahl wire rope hoist. The construct ensures that the cage moves vertically up and down without skewing left or right.

Rotomatik with the support of LISTA AG showcased our bespoke range of workspace and storage furnishings at the Aviation MRO Exhibition held at the Singapore Expo and Exhibition Centre.

The event was organised to exhibit products and services for the maintenance, repair and operations (MRO) in the aviation industry. LISTA products are widely used in the MRO operations with leading aircraft manufacturers and premium airlines.

We wanted to exhibit specialised Swiss-made workspace and storage systems for our exacting customers.

While Rotomatik Singapore is a firm believer of using technology to plug itself into the digital world, it still holds on to the traditional Asian way of eyeball-to-eyeball meeting with existing and new customers. The exhibition therefore served as a hub where there is interaction and connection with customers.

More than 5000 professionals from the aviation industry and particularly in the maintenance, repair and operations segment attended the seminar cum exhibition event.

There were over 100 visitors to our booth and many responded positively to the build quality of LISTA products. The limelight product was the LISTA Electronic Control system which has the flexibility to control access to either the entire cabinet, individual drawers or drawer compartments thereby managing security access. It is something that is quite unique in this part of the world.

Rotomatik Singapore and LISTA AG wish to thank all visitors for taking the time to view our products and to chat with us.

Visual Inspection & Tracking The Travelling of Overhead Crane

Overhead Cranes – what do overhead cranes have to do with climate change?

Climate change concerns have become more pervasive in almost every corner of the world.

The management of Rotomatik Singapore has taken the challenge to reduce carbon footprint by being part of the environmental friendly supply chain using its status as a premium crane supplier.

Rotomatik Singapore is honoured to be given a vital role in the renewable energy chain in REC Solar Pte Ltd in Singapore.

The customer is a technology provider and production of solar energy solutions.

In the Singapore plant, Rotomatik Singapore offered an overhead crane lifting solution to handle materials when there is a constraint on the lifting height.

Hence, Rotomatik Singapore designed the crane to push it as close as possible to the ceiling.

In addition, to further increase the lifting height, an extra low-headroom electric chain hoist was used, thereby fulfilling the customer’s material handling requirements.

Overhead travelling cranes using the STAHL CraneSystems STK series Extra Short Headroom electric chain hoist was the optimal solution needed for its production lines at its Tuas South plant.

The mere 185mm headroom for the 1.6 ton and 3.2 ton versions of the hoists were chosen to fit into the very low 4m ceiling and up to 3.5m high lifting height requirements of the setup. The unique design also enables loads to be lifted steadily and without swinging.

A major component of electric overhead cranes is its super structure. Basically, it comprises, runways beams, columns, rails and other parts. All these come together to form a runway for the cranes.

The back end job of designing the runway requires years of experiences.

Rotomatik (S) won another major project to prep runway and supporting columns & plates.

This is one of the number of projects won by the company as a testament of its timely delivery and quality of its worksmanship.

As shown, the materials are being packed and due for delivery to the site. Upon completion of the installation of the electric overhead crane runway, Rotomatik (S) will install a few units of overhead cranes in the next phase.

MRT depots constantly use cranes and hoists to ease the burden and increase productivity of lifting heavy loads.

MRT depots carry out a plethora of engineering & technical tasks. One of the most critical ones is the maintenance of axles which is to be done in a wheel press system.

In order to perform the maintenance work, train engineers need to heft and / or lower the axles with the help of a crane system.

Rotomatik has had the advantage of designing, installing and integrating such crane systems as part of the wheel press system in other depots. Based on its records, Rotomatik was able to rise to the challenge of engineering the system as specified by SBS Transit.

The wheel press machine is specially used for mounting and dismounting of the components of the axle such as wheel sets, brakes discs, bearings and gearboxes of rail rolling stocks.

Due to the construct of the MRT train axle, Rotomatik designed a single girder crane using not one but three chain hoists which operate either independently or in tandem.

The hoists lift and/or lower the axles to the various jigs to facilitate the inspection and maintenance of the axle elements.

The rail engineer can use either hoist “B” by itself i.e. 3.2 ton or hoist “A” & “C” together i.e. 1.6t + 1.6t. These are controlled by a smart pendant switch which controls both lifting, cross travelling and long travelling.

For safety reasons, an anti-collision system is installed to keep the hoists from colliding with each other to prevent accidents.

Jib cranes or slewing jib cranes are well-known in the material handling world that these are perfect for spot lifting.

This simply means that materials are very frequently lifted or lowered for maintenance purposes.

In the case of our customer SMRT, it has a fixed spot where items need to be worked on.

A slewing jib crane for maintenance whereby stringent requirements were specified. Consequently, after a number of discussions, a 2-tonne, 5.5 metre arm outreach with a working height of 3.5 metre was designed.

It is a testimony of the designing skills of Rotomatik.
