Underground loader (LHD, load-haul-dump scooptram)

01

Size bucket, rated capacity and dimensions for ore and drifts

Fucheng lists its diesel scooptram FCYJ-2D with a 2.0 m³ heaped bucket, 4 t rated capacity, 84 kW at 2,300 rpm Deutz F6L914 engine, 100 kN maximum traction, 80 kN maximum shovel force, 40° maximum dump angle, 8° frame oscillation, 0–8 km/h at full load, 10.5 MPa hydraulic pressure, an exhaust purifier, an articulated frame, about 7.3–7.4 m length, 1.5 m width and 2.05–2.1 m height, and 12 t weight with hydraulic oil. [1]

Its cable-electric FCYJ-0.75E has a 0.75 m³ heaped bucket, 1,500 kg rated capacity, 37 kW rated power, 41 kN traction, 39 kN shovel force, 0–8 km/h, 16° gradeability, 2,350 mm minimum turning radius, ±36° articulation, 195 mm ground clearance, 3,600 mm maximum bucket height, 850 mm maximum discharge height, 5.8 × 1.25 × 1.9 m dimensions and 6.5 t weight. [2]

Editorial calculation: both models' rated capacity divided by heaped bucket volume is 2.0 t/m³ (4 t / 2.0 m³ and 1.5 t / 0.75 m³). If your broken ore is denser, a full heaped bucket exceeds rated capacity, so ask for the bucket size matched to your loose ore density. On the 2 m³ machine, 4 t is one-third of the 12 t machine weight. [1] [2]

Give the supplier the ore or rock type and loose density, fragment size, production rate and haul distance, drift width and height, turning radius and gradients, dump point (ore pass, truck, stockpile), power (diesel, cable-electric, battery), ventilation and emission rules, altitude and temperature, fire suppression and safety requirements, and service and parts support expected.

02

Choose diesel or electric drive and meet diesel rules

In US underground metal and non-metal mines, MSHA's 30 CFR 57.5060 limits a miner's personal exposure to diesel particulate matter to an eight-hour equivalent full-shift average of 160 micrograms of total carbon per cubic metre of air (effective 20 May 2008). Under 57.5067, any diesel engine introduced underground after 5 July 2001 must carry an MSHA approval plate or meet the EPA particulate limits listed in its table, for example 0.30 g/kW-hr for Tier 2 nonroad engines of 75–130 kW. Section 57.5065 limits underground diesel fuel to 0.05% sulphur and requires EPA-registered fuel additives. [3] [4] [5]

Editorial calculation: the FCYJ-2D's 84 kW engine falls in the 75–130 kW row of the 57.5067 table, so for US use it would need an MSHA approval plate or proof that it meets 0.30 g/kW-hr particulate; ask the supplier for the engine's emission certificate. The cable-electric FCYJ-0.75E has no diesel exhaust and is powered through a cable on a cable drum; ask for the cable length and supply voltage, which set where it can work. [4] [1] [2]

Editorial note: national mining rules differ; give the supplier the jurisdiction and the ventilation and emission requirements that apply to the mine.

03

Scooptram ranges and the underground trucks sold beside them

The suppliers reviewed list diesel and electric LHD loaders, and some also list underground trucks; ask each for rated capacity and bucket options, dimensions, engine emission certification or motor and cable data, fire suppression, brakes, and parts and service support.

04

Trace the loader systems

The engine-and-purifier row is where the MSHA engine rule bites; on the cable-electric FCYJ-0.75E the motor and cable drum take its place.

05

Bucket, power and clearance entries for a drift-sized LHD

Set rated capacity against your ore and machine width and height against your drifts before anything else. Tyres, noise, materials, climate and duty cycle are not given on Fucheng's pages and have to come from the supplier.

06

Send the ore, drift and power data together

Paste it into your enquiry below or into an email to a maker, then replace every bracket.

Ore: [type; loose density; fragmentation]
Production: [t/shift; haul distance]
Drifts: [width; height; gradients; turns]
Dump: [ore pass; truck; stockpile]
Power: [diesel; cable; battery]
Rules: [jurisdiction; DPM; engine approval]
Safety: [fire suppression; brakes; cab]
