GHH to deliver LHDs, trucks to Breznik gold project in Bulgaria

Germany-based machine manufacturer GHH says it has significantly expanded its market share in Bulgaria with a double-digit number of LHDs and trucks set to head to Breznik Minerals Ltd.

The Bulgarian company is part of the group of companies of Assarel-Medet JSC, which is the leading mining company in the country, carrying out both open-pit mining and copper ore processing.

The acquired machines will be operated in the Breznik gold project, which is the first underground greenfield mine set to be built in Bulgaria for more than 50 years, according to the company. The site has an area of 500,000 sq.m and is some 35 km west of Sofia. The deposit has JORC indicated resources of approximately 1 Mt grading 2 g/t Au and inferred resources of approximately 700,000 t grading 1.8 g/t, along with significant silver resources.

Breznik will take delivery of the first batch of equipment in the September quarter of 2024, with the remainder scheduled for the end of the June quarter of 2025.

“We are looking forward to the delivery of their first GHH machines,” Krum Hristov, one of the founders of Strotech Engineering JSC, a construction, industrial and mining equipment specialist based in Sofia, Bulgaria, which runs several fully-equipped service centres throughout the country, maintaining 2,000 units per year.

The recent order consists of LF-7 LHDs, and MK-20 and MK-30 diesel-powered dump trucks.

The LHDs are designed for a payload of 7 t in bucket sizes up to 4 cu.m. They have the best loading performance in their class at only 2.2 m total height, fully laden, GHH says. The LF-7 is powered by a 164 kW Tier 3/4/Stage 5 engine, comes with a robust design and offers extra safety and comfort for the driver.

The dumpers are designed with 20 t and 30 t of payload, up to 18 cu.m dump box capacities and engines with up to 320 kW power rating. GHH claims that the low operating costs offered by the machines are made possible by the unique frame and system design.

All vehicles can also be monitored remotely to manage maintenance with the GHH inSiTE software, providing a big plus when it comes to machine availability and cost savings.

GHH launches new 10-loader, the LF-10 NEO

Mining and tunnelling equipment manufacturer GHH has unveiled a new load haul dumper (LHD), the LF-10 NEO, offering, it says, the highest tipping height in its class.

This 10-t-payload loader is a powerful and compact machine and an improved version of the LF-10, already a well-established product in its class, the company said. It is the latest in a line of new GHH loaders that includes the LF-14, the LF-7 and the LF-8.

The LF-10 NEO has a z-link design and a maximum tipping height of 2.5 m. This makes it an ideal partner for loading all 30-t-payload trucks on the market, according to GHH.

“The high breakout forces, efficient boom and bucket motion times, as well as the strong power to weight ratio, makes the LF-10 NEO one of the best in class,” Ingo Rath, Product Line Manager Loaders at GHH in Germany, said.

With a length of 9.6 m and width of 2.6 m, the LF-10 NEO is compact and versatile for excellent manoeuvrability in mid-seam underground mining environments, according to GHH.

The standard bucket aboard the LF-10 NEO holds 4.6 cu.m, making loading and unloading easier and more cost effective.

With an operating weight of around 28 t, the loader manages speeds of up to 32 km/h with four-speed transmission and gradients up to 25%. It is able to tip the 10-t payload in just 2.6 seconds, GHH says.

“GHH installs the water-cooled Mercedes OM936 diesel engine with 240 kW, which is the best in the 10-t loader-size class,” Rath says. “The large fuel tank also allows for full shift operation with no worry for refuelling mid shift and losing valuable production time.”

Exhaust gas emissions comply with US EPA Tier 3 or EU Stage IIIA on the standard machine, while EU Stage V is also optional. The low fuel consumption, ease of maintainability and robust design as well as durability and reliability of the product all add to the low operating costs, the company said.

The LF-10 NEO has an operator compartment that boasts excellent ergonomics, GHH says. This is evident in the way the controls have been laid out and the general arrangement within the cabin. There is also a large footbox within the cab, providing the operator with significantly more space and comfort. The cab also offers improved visibility compared with other loaders in the class.

It comes as standard with useful safety and maintainability features such as the Proximity Detection System (PDS) interface, which allows the integration of third-party equipment. There are also optional wear sensors fitted on the brakes.

“Like other GHH vehicles, the articulated LF-10 NEO is designed for underground hard-rock mining and can be ordered with many options,” GHH said.

It also seamlessly integrates with the GHH inSiTE electronic monitoring and digital analytics system, which provides insight into the machine performance and maintenance requirements, all tailored to the specific needs of customers.

GHH concluded: “The NEO joins the company’s mid-range segment of LHD offering, which is one of the most comprehensive on the market: the range of 18 diesel and electric models with payloads from one to 21 tonnes is a weighty factor in choosing the perfect loader. And, by the way, the Germans have the same great selection in dump trucks to complement.”

GHH delivers first LF-7 LHD to Indian market

A month after announcing the first delivery of a Tembo 4×4 electric light vehicle to India, GHH says it has now shipped the first LF-7 LHD to the country.

The vehicle was shown at the Mining Expo in Kolkata, in April, with GHH then arranging the onward transport to the unnamed launch customer, who also ordered further machines from the OEM.

The previously delivered Tembo 4×4 ELV, which went to Hindustan Zinc, is an electric multi-purpose light duty vehicle based on the Toyota Land Cruiser and Hilux models. It is available in many versions ranging from a pickup truck to a passenger transporter (10 seats). GHH is a regional distributor of the vehicle.

According to GHH, the LF-7 currently offers the largest bucket, most powerful engine and best climb performance in its class.

It carries 7 tonnes or 3.6 cu.m, is 8.9-m long in driving position, 2.24 m-wide at the bucket and 2.2-m high at the cab when fully loaded. This makes the LF-7 suitable for narrow-vein operations, as well. The loader is powered by a 164 kW Cummins diesel engine and complies with Tier 3/4 and EU Stage V emissions standards, GHH says.

Maintenance requirements are eased with the addition of GHH InSiTE software, which allows vehicle data to be called upon in real time and evaluated.
