Capital Equipment News November 2018On the cover:

In this edition of Capital Equipment News, the leading story focuses on the arrival of the new SANY SY500H excavator in South Africa. In a deal worth around R12-million, Goscor Earth Moving has delivered the first three units of the mining excavator to mining and beneficiation company, Africa Mining Group (AMG).

The 50 t SY500H is the second-biggest model in SANY’s large excavator line-up, and forms part of the Chinese OEM’s mining range, which also comprises the 36-t SY365H and the recently-launched 75-t SY750H.

Scott Yuan, COO at AMG, says the three units have already been deployed at the company’s Kathu, Northern Cape mining project. Joining AMG’s existing fleet of 10 excavators, 10 dump trucks and six front-end loaders, the three SY500H excavators will be deployed for the expansion of the existing mining area in order to increase monthly production.

A high configuration digging machine, the SANY SY500H ticked all the right boxes for AMG. The machine is designed with customers’ return on investment in mind – with an array of features that speak to high efficiency, long operating life and high reliability.

Powered by an Isuzu engine delivering rated power of 300 kW @ 1 800 rpm, it has an operating weight of 49 500 kg. Equipped with a 2,5 m³ bucket, it offers bucket digging force and arm digging force of 287 kN and 245 kN, respectively. Through SANY’s independently-developed engine pump valve control technology, the average working efficiency of the excavator has increased by 7,5%.

The machine also boasts a proprietary Dynamic Optimisation Matching Control System which perfectly matches the hydraulic system. The advanced control system not only boosts operating efficiency by 7,5%, but also reduces fuel consumption by 10%.

Latest compact excavators on arrival lounges

As the compact excavator continues to dig for a sizeable share of the local yellow metal equipment market, several leading suppliers have recently introduced new offerings or updated models to the market.

The compact excavator is deemed the next ‘big’ piece of equipment in the global equipment market. However, the local market still remains small compared with its developed counterparts. Despite the gradual uptake of the solution, local suppliers believe the compact excavator will eventually dig for a sizeable share of the market in the long term.

There are several new launches from many of the active participants in the southern African compact excavator market. Bell Equipment entered the market for the first time with the introduction of its three models from its new excavator partner, Kobelco. Force 8 has also recently launched a new 10 t model from its principal, YANMAR, while HPE Africa, the local supplier of Hyundai Construction Equipment has seen constant improvements being made to its existing models.

Unique fall protection challenges for mobile cranes

Construction regulations demand that measures be put in place to address the risk of falling from height, but the mobile crane segment has particular needs that require users, manufacturers and even regulators to consider.

Johnson Crane Hire Safety 11 2018 001

According to Cedric Froneman, Johnson Crane Hire’s executive for safety, health, environment and quality (SHEQ), there are unique risks facing crane crews, due to the height of most mobile cranes being less than 4 m from the ground often with inadequate anchor points available.

“There are unique challenges when dealing with large mobile cranes, leading to a fall factor of two – signifying the most dangerous level – for the crane crew moving around on top of a machine,” says Froneman. “Compared to a fall factor of zero, where the workman’s lanyard can be attached to an anchor point above their head, most mobile cranes only have attachment points at waist level or even sometimes only at feet level.”

Given the relatively low height of some mobile cranes, it is also possible that anyone falling may reach the ground before the shock absorbing lanyard can take their weight, essentially providing no fall protection.

“So, we can’t rely on the fall-arrest principle,” he says. “We rather need to focus on fall-restraint systems, and this relies largely on the crane original equipment manufacturer (OEM) to put systems in place on the mobile crane to stop the workman from falling in the first place.”
