Презентация на тему Jcb loadall 550-80 vs merlo p55.9. Superior by design

forward extension with maximum payload, predominantly above the chassis

maximum loading being above the chassis
Increased maximum boom angle

detail
Built to last
JCB Loadall’s can dig, not just lift

3

combined with JCB gearbox, hydraulic rams, cab, chassis and

Less control of quality and supply through various externally sourced componentry
103kW (138hp) Deutz engine provides less power than the JCB 145hp engine
Sauer Danfoss hydrostatic transmission

4

strength and weight to the chassis structure
Long, thick deck

Thin 20mm thick side plates reduce structural strength
2 piece chassis with rear joint reduces structural rigidity
Enclosed compartments easily collect debris and dirt

5

axle feet or sway casting comprehensively absorb stress caused

Sway chassis as standard
Little use of heavy duty componentry
Digging forces absorbed through axles which causes high stresses and potential early life failure

6

linkage to maximise the tear out force of 6650

7

Merlo uses under-slung tilt ram and pivot linkage
Reduced productivity particularly when re-handling
Minimal boom nose reduces structural strength and integrity

maximise structural integrity and rigidity
Boom is purpose built for

8

excellent wear protection, reduced dirt adhesion and reduced servicing
U

9

2 off welded ‘C’ shape sections absorb the stresses into the joint and can cause early life failure
Boom nose welded onto the end of these box sections is where lifting forces are dispersed, therefore putting continual stresses onto the joint

even dispersion of lifting forces throughout the boom structure
Provides

Merlo also use one centrally mounted lift ram
1 offset displacement ram
Structural unevenness can put twisting forces into the boom and cause wear

10

total combined cycle time as shown
Re-generation hydraulics provide significantly

11

perfect harmony of operation
4 speed Powershift gearbox provides fast

12

Merlo uses Deutz engine and Sauer Danfoss drive motor, reducing integration of major components
Continuous speed cooling fan as opposed to variable speed, can increase power/fuel consumption and therefore operating costs

hand display facilitates clear and concise operator feedback
Logically grouped

Basic styling of cab layout with separate panels for displays as opposed to integrated units
ADHOC positioning of switches increases complexity of operations and reduces productivity

13

and responsive control of the hydraulic services
Ergonomically designed joystick

ADHOC positioning of joystick and armrest facilitate an uncomfortable operator environment to increase fatigue
Cab mounted option only reduces machine versatility
‘Dead man switch’ uncomfortable to use

14

powershift gears on steering column lever makes direction and

Forward/reverse switch difficult to access on the steering column, therefore increasing change times and reducing productivity
Manual steer mode change as standard can reduce productivity when compared to auto steer mode

15

off brakes which facilitates less energy consumption
Power brakes are

P55.9 utilises standard service disc brakes which required increased effort for operation therefore increasing operator fatigue
Use of inching pedal increases the number of operations during use therefore reducing productivity

16

adjustable vents, giving excellent all round ventilation
An air conditioning

P55.9 has the heater unit mounted to the rear of the cab seat therefore reducing in cab storage space and impacting on operator comfort

17

steps facilitate ease of access/egress
Recessed diesel cap for maximum

Small gap between cab steps making access in and out more difficult
Exposed diesel cap is susceptible to damage potentially increasing the cost of ownership
Structurally integral tank increases down time if damaged

18

ease of access into the cab
Lower glass door panel

2 small grab handles, one not fixed makes ingress/egress timely
Small lower door glass panel reduces operator visibility
Thick roof bars reduce upward visibility to reduce productivity and increase fatigue

19

bonnet gives extensive access for servicing
All service points are

Service access is dramatically restricted through low opening bonnet
Fixed engine under cover makes all round access to the engine timely therefore increasing downtime and reducing productivity

20

throughout the chassis when laden
Low boom pivot point in

Use of 50mm thick chassis plate at rear reduces need for counter weight but also reduces structural rigidity through added joints and welds
Can lead to early life failure and costly repairs

21

the rear lights for roading and non roading
Increased protection

Static rear and front lights mounted on fixed front and steering rear fender arms
High exposure to damage increases ownership costs

22

design life
In house manufacture of major components for quality
