Mining excavator parameters

1. Generally speaking, 80 machine is 8 tons, 100 machine is 10 tons, like Komatsu brand machine, Komatsu 120 is 12 tons, of course, there are special features.

2. The important parameters of excavator can be seen in the operation manual. The name plate on the excavator will indicate the excavator model, engine power, origin and other information.

Operating weight
operating weight is one of the three important parameters of excavator (engine power, bucket capacity and operating weight)
operating weight determines the level of excavator and the upper limit of digging force
excavation force ≤ m; Working weight
m: adhesion coefficient between the ground and the track
if the digging force exceeds this limit, the excavator will slip and be pulled forward in the case of backhoe, which is very dangerous. In the case of a forward shovel, the excavator will slip backward
digging force
for digging force, digging force is mainly divided into jib digging force and bucket digging force
the action point of the two digging forces is the tooth root of the bucket (the lip of the bucket), but the power is different, and the digging force of the jib comes from the jib cylinder; The digging force of the bucket comes from the bucket cylinder
ground pressure
the ground condition of excavator is determined by the ground pressure
grounding pressure refers to the pressure proced by the weight of the machine on the ground, which is expressed by the following formula:
grounding specific pressure = working weight ÷ It is very important to install proper track shoes on the machine. For crawler excavators, the selection criteria of crawler are: as long as possible, try to use the narrowest crawler shoes
· common crawler types: toothed crawler shoe,
walking speed
for crawler excavator, walking time accounts for about one tenth of the whole working time
generally speaking, two speed can meet the walking performance of excavator
tractive force
tractive force refers to the force generated when the excavator is walking, which mainly depends on the walking motor of the excavator
these two walking performance parameters indicate the mobility and walking ability of the excavator. It can be reflected in the samples of various manufacturers
climbing ability
climbing ability refers to the ability to climb, descend, or stop on a solid, flat slope
there are two ways to express: angle, percentage
lifting capacity
lifting capacity refers to the smaller of rated stable lifting capacity or rated hydraulic lifting capacity
rated stable lifting capacity: 75% tipping load
rated hydraulic lifting capacity: 87% hydraulic lifting capacity
slewing speed
slewing speed refers to the average maximum speed of stable slewing when the excavator is no-load
this means that the defined turning speed does not refer to the turning speed when starting or braking; That is to say, it is not the speed of acceleration or deceleration. For the general excavation work, this kind of excavator at 0 ° To 180 ° When working within the range, the rotary motor has acceleration or deceleration, when turning to 270 ° To 360 ° Within the range, the rotation speed is stable
therefore, in the actual excavation work, the rotation speed defined above is impractical. That is to say, the actual slewing performance required is acceleration / deceleration represented by slewing torque
engine power
gross horsepower refers to the output power measured on the engine flywheel without consuming power accessories such as muffler, fan, alternator and air filter
net horsepower refers to the output power measured on the engine flywheel with all power consuming accessories, such as muffler, fan, alternator and air filter
Noise Measurement
the noise of excavator mainly comes from engine
two kinds of noise: the noise measurement in the operator's ear and the noise measurement around the machine

4. Please ask specific questions, otherwise it's really hard to answer your questions. For example, you want to know which brand and model of machine, so as to tell you the relevant parameters. Such as vehicle weight, engine model, power, speed, hydraulic pump model, displacement, walking motor model, displacement, working pressure, rotary motor displacement, working pressure, etc.

extended data

the meaning of excavator parameters is as follows:

operating weight

operating weight is the three important parameters of excavator (engine power, bucket capacity, Operating weight [4]

the operating weight determines the level of excavator and the upper limit of digging force

excavation force ≤ m; Working weight

m: adhesion coefficient between the ground and the track

if the digging force exceeds this limit, the excavator will slip and be pulled forward in the case of backhoe, which is very dangerous. In the case of a forward shovel, the excavator will slip backward

excavation force

for excavation force, excavation force is mainly divided into jib excavation force and bucket excavation force

the action point of the two digging forces is the tooth root of the bucket (the lip of the bucket), but the power is different, and the digging force of the jib comes from the jib cylinder; The digging force of the bucket comes from the bucket cylinder

ground pressure

the ground condition of excavator is decided by the ground pressure

ground pressure refers to the pressure proced by the weight of the machine on the ground, which is expressed by the following formula:

ground specific pressure = working weight ÷ The total contact area with the ground

track shoes

· it is very important to fit the machine with suitable track shoes. For crawler excavators, the selection criteria of crawler are: as long as possible, try to use the narrowest crawler shoes

· common crawler types: toothed crawler shoes

walking speed

for crawler excavators, walking time accounts for about one tenth of the whole working time

Generally speaking, two speed can meet the walking performance of excavator

tractive force

tractive force refers to the force generated when the excavator is walking, which mainly depends on the walking motor of the excavator

These two walking performance parameters indicate the mobility and walking ability of excavator. It can be reflected in the samples of various manufacturers

climbing ability

climbing ability refers to the ability to climb, descend, or stop on a solid, flat slope

two ways: angle, percentage

lifting capacity

lifting capacity refers to the smaller of rated stable lifting capacity or rated hydraulic lifting capacity

rated stable lifting capacity: 75% tipping load

rated hydraulic lifting capacity: 87% hydraulic lifting capacity

slewing speed

slewing speed refers to the average maximum speed of stable slewing when the excavator is no-load

this means that the defined turning speed does not refer to the turning speed when starting or braking; That is to say, it is not the speed of acceleration or deceleration. For the general excavation work, this kind of excavator at 0 ° To 180 ° When working within the range, the rotary motor has acceleration or deceleration, when turning to 270 ° To 360 ° Within the range, the rotation speed is stable

therefore, in the actual excavation work, the rotation speed defined above is impractical. That is to say, the actual slewing performance required is acceleration / deceleration represented by slewing torque

engine power

gross horsepower refers to the output power measured on the engine flywheel without consuming power accessories such as muffler, fan, alternator and air filter

net horsepower refers to the output power measured on the engine flywheel with all power consuming accessories, such as muffler, fan, alternator and air filter

Noise Measurement

the noise of excavator mainly comes from engine

two kinds of noise: the noise measurement in the operator's ear and the noise measurement around the machine
