Goods Hoists

Goods hoists are a versatile transporting equipment in the manufacturing and logistics industries.

An Oil & Gas (O&G) multi-national company which manufactures petroleum products was in the process of constructing a new plant. After reviewing its internal logistics processes, the management realised it needed an internal material handling system to accelerate its materials movement to the Level 3 of its new plant.

Two important criteria were established with potential suppliers from the outset of the construction project. Goods are to be moved from ground level to level 3. The products are classified as dangerous goods.

Rotomatik Singapore presented their flagship explosion-proof goods hoists. The goods hoist is designed to carry 5 tonne of dangerous goods.

Rotomatik decided to supply a 10-tonne hoist for future expansion with a configuration of 4/2 meaning the cage can carry higher load and the cargo will be lifted up true vertically. However, overload sensors are in-built to restrict loads up to and including 5 tonnes.

Lifting of Goods Hoist Cage

The cage is made of stainless steel with all the standard safety features such as door sensor, interlocking mechanism, safety catches and many others redundant features which will offer a fail-safe system.

Construction schedule requires the goods hoist shaft to be built in tandem with the building structure. The challenge was in the installation process.

Part of the execution is the stainless steel cage has to be lifted over 40 metres by a mobile crane and carefully lowered into the goods hoist shaft, followed by the explosion proof hoist and all its explosion proof panels. A well-oiled operation indeed.

Every task was done by trained technicians and double checked by engineers and quality checked by our QC engineers.

The entire order-to-installation process began in 2018 and it was finally installed towards the end of 2019.

Jib cranes are one vital lifting equipment used in O&G industry.

Rotary Engineering is a leading oil and gas (O&G) infrastructure services company in the region located in Singapore.

It is an EPC to the O&G, petroleum, petrochemical and pharmaceutical industries.

Rotary Engineering is a key partner with Rotomatik Singapore in such markets and industries.

As a result, in 2019, Rotomatik Singapore was asked to supply 4 units of explosion-proof slewing jib cranes to PSW (Padauk Shwe War) Terminal in Thilawa Port. This is located in the Republic of the Union of Myanmar.

Since the slewing jib cranes are used in an explosive environment, each one is designed and built with an SH3 explosion proof wire rope hoist designed to carry 1.5 tonnes. Each arm has an outreach of 10 metres.

The slewing jib cranes are used for the maintenance of pumps located in a classified area which requires explosion proof equipment.

Jib Crane

Jib cranes or slewing jib cranes have many applications in any type of industry. An example of the use of slewing jib cranes in the consumer packaged goods firm.

The task of changing rolls of paper used in a production process can have a detrimental effect to the health of employees as far as ergonomic well-being is concerned.

An MNC of consumer packaged goods which practises HSE (Health, Safety & Environmental) asked for a system which allows the use of mechanised system to aid in the loading of paper rolls.

Rotomatik Singapore used a number of slewing jib cranes attached 160 kg electric chain hoists with an arm lengths ranging from 2 to 3 metres with a lifting height of 2.2 metres.

Jigs as part of the slewing jib cranes also supplied by Rotomatik Singapore to handle rolls of papers and other materials are attached to the hoist hooks.

The jib system allows operators to load new rolls with ease preventing long-term injuries to their workers.

Beautifully Crafted Slewing Jib Crane

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.
