HOW HERCULES SLR IN HAMILTON, ONTARIO MAKES A GIGANTIC WIRE ROPE SLING

What are we up to at Hercules SLR in Hamilton, Ontario? We’re making big things – a big wire rope sling, specifically.  

Check out these shots of Bryan Jarret, Production Supervisor and Adam making a sling for crane-use. It takes both of these guys just to hold it! 

So, how do Hercules SLR rigger’s make a sling this big? We’ll show you. 

WIRE ROPE SLING MAKING—WATCH HOW IT’S DONE

This is Bryan Jarret, our Production Supervisor at Hercules SLR in Hamilton, Ontario. Here, he’s pressing these huge lengths of wire rope to form a 6-foot eye on each end. 

This large sling will eventually be used on a crane for one of our clients’ here in Ontario. 

HOLDING A SLING IS A TWO-MAN JOB

A sling this size takes about 1-hour to splice. Each foot weighs about 15-20 pounds on its own. One technician holds the sling, while the other technician splices the opposite end. 

FORMING THE WIRE ROPE SLING EYE

A wire rope this size has a WLL of 76,000lbs. If these two rigging technicians were standing on top of one another, the sling would still be taller than both of them! 

BIG WIRE ROPE SLINGS NEED BIG MUSCLE

Here, they complete the pressing/swaging process on the other side. As the wire rope strands become tighter, the technicians must manually bend through the eye, which takes a lot of arm-strength!  

There you have it, folks—Here’s how our riggers make a sling that lifts BIG things.

Modular Construction Trending: Innovative Workspaces

modular construction project hercules slr

WHAT’S MODULAR CONSTRUCTION? 

Modular construction allows significant portions of work to be completed, off-site and usually inside in a modular workspace. It doesn’t describe the building itself, but the way it’s built. 

Many think of a mobile home or re-locatable building when they think of prefabricated buildings, but modular construction has become more modern and sophisticated in recent years, which has led to more modular working spaces. Modular construction can be used to build either residential or commercial buildings, although commercial is the most common. 

A modular working approach to construction tends to focus on manufacturing—Read on for an example.  

EXAMPLE: A construction crew builds an office building. Instead of assembling the entire project on-site, individual parts are manufactured indoors. The crew would assemble individual wall panels indoors, and these will later be put up on-site. 

Other parts of the project could be assembled here, too—think washrooms, pre-built wall panels, ped-ways, stairs, and even the roof. 

These parts are assembled in the modular workspace, transported and put together on-site as the construction project progresses—these prefabricated parts are put together with lifting equipment like cranes or aerial lift trucks.

WHAT ARE THE BENEFITS?

Since modular workplaces are a bit different than traditional construction sites, they can also reduce some of the risk or hazards found on typical construction sites. Safety can be enhanced by modular construction:

  • Less work at height—for example, on many modular projects a roof is lifted to the top with a crane. 
  • Reduce garbage and waste—working off-site can limit the amount of extra material thrown away, and can be recycled for future use. 
  • Community disruption—modular construction and workspaces bring work off-site, making the area more quiet! For example, let’s say you’re building an office on a University campus. Modular construction frees the campus from common construction disruptions (loud machinery, dust, barricades, etc.). 
  • Time—they say time is money, and modular construction can save time compared to working on-site. Prefabrication often takes about half the time and many pieces can be made at once, which lets contractors take on multiple projects, schedules can be planned more ‘tightly’ and projects are finished quickly.  
  • Remote Locations—Modular construction allows work to be taken off-site, which can be a great benefit for more isolated locations. Think—a house in Northern Alberta is mainly assembled indoors, so workers can do less work in frigid, outdoor temperatures. 

MODULAR PROJECTS

One notable modular construction project is the 57-storey skyscraper built in China by entrepreneur Zhang Yue, in just 19 days—yes, you read that right, a whole skyscraper assembled in 19 days altogether. Specifically, the first 20 storeys were assembled in seven days, but various regulations held the project up for a year before the last 37-storeys were built in 12 working days. The final skyscraper has offices that fit 4,000 people, 800 apartments and 19 atriums. 

Zhang has built a number of other buildings using the same method. A skyscraper built using traditional, on-site construction takes about 2-3 years compared to the days Zhang’s projects take to complete.

FINAL THOUGHTS

Overall, modular construction reduces uncomfortable environmental conditions for workers and clients, increases productivity and can reduce harm and injuries.

Traditional construction sites will always have a place in the industry, but it’s an exciting innovation that’s sure to shake things up.

Steel Cable: market growth driven by automotive industry

steel-cable-wire-rope-filaments

The steel cable or wire rope market expects to grow at a CAGR (compound annual growth rate) of 4.2% in the coming period heading into 2023, reports PR Newswire.

Wire rope or steel cable provides strength, flexibility and has many applications. Steel cable is used in elevators, rigging and lifting applications, theatre sets, and is used as a reinforcing material for automotive tires and conveyor belts.

Filaments, which are fine strands of steel are significantly useful for the fabrication of automotive tires. Advantages of wire rope or steel cable filaments include high thermal resistance a better travelling performance. Currently, the global wire rope market is being greatly influenced by market entrants in the automotive industry.

Example of fraying wire rope—notice the individual strands that make up each rope.

Right now, technology and a need for lighter tires are two growing demands in the automotive industry. Flat-run tires, eco tires and nitrogen tires are three examples of tech-driven tires that create a demand for a flashier, updated tires for manufacturers. Their industry has a need for lighter tires, which means steel cable will be a sought-after material for automotive fabrication. These steel cable filaments will be used in application for heavy equipment tires, cargo truck tires, conveyor belts, rubber framework and light truck tires.

As the famed architect Walter Grophius said, “New synthetic substances—steel, concrete, glass—are actively superseding the traditional raw materials of construction.” Even in modern days, fabrication and manufacturing industries are constantly finding news ways to use to use familiar, synthetic materials.

Wire Rope: A Manufacturing & Transportation Pioneer

Wire-Rope-Pioneer
Early Life

Andrew Smith Hallidie was born Andrew Smith, later adopting the name Hallidie in honour of his uncle, Sir Andrew Hallidie. His birthplace is variously quoted as London in the United Kingdom. His father, Andrew Smith (a prolific inventor in his own right, responsible for inventing the first box door spring, a floor cramp and had an early patent for wire rope) had been born in Fleming, Dumfrieshire, Scotland, in 1798, and his mother, Julia Johnstone Smith, was from Lockerbie, Dumfriesshire.

The younger Smith was initially apprenticed to a machine shop and drawing office. In 1852 he and his father set sail for California, where the senior Mr. Smith had an interest in some gold mines in Mariposa County. The mines proved disappointing, and he returned to England in 1853. Andrew Smith Junior, however, remained in California, and became a gold miner whilst also working as a blacksmith, surveyor and builder of bridges.

Inventions

In 1855, young Hallidie built a wire suspension bridge and aqueduct 220 feet long at Horse Shoe Bar on the Middle Fork of the American River. During 1856, whilst working on the construction of a flume at a mine at American Bar, the now, Andrew Smith Hallidie was consulted over the rapid rate of wear on the ropes used to lower cars of rock from the mine to the mill. These ropes wore out in 75 days—unsatisfied with this, Hallidie manufactured rope for the project consisting of three spliced pieces one-eighth of an inch thick, 1200 feet long. These lasted for two years—a vast improvement from the previous 75 day standard.

Hallide invented the Hallidie Ropeway, a form of aerial tramway used for transporting ore and other material across mountainous districts in the west, which he successfully installed in a number of locations, and later patented. After a few years of drifting from camp to camp working claims, narrowly avoiding disasters both natural and man-made, and briefly running a restaurant at Michigan Bluff in the Mother Lode, he abandoned mining in 1857 and returned to San Francisco. Under the name of A. S. Hallidie & Co., he commenced the manufacture of wire rope in a building at Mason and Chestnut Streets, using the machinery from American Bar.

In addition to aerial tramways, his rope was used to build suspension bridges across creeks and rivers throughout northern California. He was often away from the City on his bridge projects until in 1865 he returned to San Francisco and focused his energies entirely on manufacturing and perfecting wire rope. The discovery of the Comstock Lode silver mines in Nevada increased the demand for wire rope.

The city became a major industrial center for mining operations in the 1860s and Hallidie prospered, becoming a leading entrepreneur, US citizen, husband to Martha Elizabeth Woods, and in 1868 President of the prestigious Mechanic’s Institute.

Hallidie’s ‘Endless Wire Ropeway’—Precursor to Cable Cars

It was about this time that Hallidie began to implement a scheme for urban transportation he had been considered for some time, based upon his use of wire rope for the aerial tramways. He worked on improving the tensile strength and flexibility of his wire to develop an “endless” wire rope that could be would around large pulleys, which could then provide continuous underground propulsion for a car that could be attached or released at will from the cable. Hallide took out a patent Endless Wire Rope Patentfor this “Endless Wire Ropeway” and for years it dominated the construction of tramway at mines throughout the West. However, it was the implementation of his Endless Wire Ropeway for moving streetcars in San Francisco that brought him lasting fame and a place in the history books.

It is here accounts differ as to exactly how involved Hallidie was in the inception of the first cable car at Clay Street Hill Railway. One version, has him taking over the promotion of the line when the original promoter, Benjamin Brooks, failed to raise the necessary capital.

In another version, Hallidie was the instigator, inspired by a desire to reduce the suffering incurred by the horses that hauled streetcars up Jackson Street, from Kearny to Stockton Street.

There is also doubt as to when exactly the first run of the cable car occurred. The franchise required the first run no later than August 1, 1873, however at least one source reports that the run took place a day late, on August 2, but that the city chose not to void the franchise. Some accounts say that the first gripman hired by Hallidie looked down the steep hill from Jones and refused to operate the car, so Hallidie took the grip himself and ran the car down the hill and up again without any problems.

The named engineer of the Clay Street line was William Eppelsheimer. Given Hallidie’s previous experience of cables and cable haulage systems, it seems likely that he contributed to the design of the system.

The Clay Street line started regular service on September 1, 1873, and was a financial success. In addition, Hallidie’s patents on the cable car design were stringently enforced on cable car promoters around the world and made him a rich man.

A. S. Hallidie & Co. became the California Wire Works in 1883 with Hallidie as president. In 1895, it was sold to Washburn and Moen Co., the oldest manufacturers of wire in the United States (established in 1831).

Hallidie died on April 24, 1900 at the age of 65 of heart disease at his San Francisco residence, but his name lives on. In San Francisco, Hallidie Plaza (near the Powell and Market Street cable car turntable) and the Hallidie Building (an office building in the city’s Financial District) are named after him.
