Kobelco SK480DLC-8 & SK500DLC-8 Demolition Machine Shop Manual – Section 61 Common Use Type Main Boom

Description

Kobelco SK480DLC-8 & SK500DLC-8 Demolition Machine Shop Manual — Section 61: Common Use Type Main Boom

This is the Section 61 shop manual for the Kobelco SK480DLC-8 and SK500DLC-8 demolition machines fitted with the common use type main boom. It is the service volume that picks up where the standard excavator shop manual ends: the dedicated reference for the 3-piece demolition ultra long attachment (LMN), the separate boom, and the demolition backhoe, covering the hydraulic, electrical, mechatronic and structural systems that are specific to these demolition configurations. Every procedure in this Kobelco SK480DLC-8 SK500DLC-8 demolition machine shop manual is written for the technician who has to test, adjust, disassemble and reassemble the demolition front end and the systems that support it — not for the base machine alone.

General View and Attachment Configurations (61.1–61.3)

The opening chapters set the scene for the demolition package. You get the component breakdown for the 3-piece demolition type, the long-arm spec, the separate boom type and the backhoe type; overall dimensions for the mechanical VLC, rigid LC and hydraulic VLC undercarriages; crusher (nibbler) illustrations for the KR1100TPR and KR1200PR; full machine dimensions for each boom, insert boom, front boom, inter boom and arm combination; transportation dimensions; counterweight specifications; bucket types; crusher weight limits; and the working range charts for the ultra long attachment, separate boom and demolition backhoe. The HINO P11C-UP engine specifications and its performance curve are printed here as well.

Maintenance Standards and Test Procedures (61.4)

This is the measurement chapter. It opens with the pressure adjustment standard tables for the ultra long attachment (LMN) and the separate boom large-diameter jib cylinder spec., then moves into the performance inspection standard tables — engine speed, pilot primary pressure, main relief, over-load relief settings — and the operating speed standards for travel, swing and every attachment cylinder. You also get the procedure for measuring hydraulic pressure, where to install gauges on the main pump and control valve, how to adjust the pilot relief, main relief, over-load relief and swing/travel relief valves, how to measure travel speed and travel deviation, drain rates for the travel and swing motors, cylinder operating times, cylinder oil tightness, swing bearing play, and the mechatronic controller A/B adjustment with the multi-display feedback screens.

Mechatronic Control System (61.5)

The control chapter explains the electro-hydraulic side of the demolition package in detail: positive control and P-Q control, boom-up conflux, arm-in recirculation and conflux, arm-in anti-cavitation, arm-out conflux, bucket digging (dump) conflux, bucket digging anti-cavitation, swing priority, travel straight, pressure release, N&B switch control, and option conflux. The multi-display section covers screen selection, attachment mode selection, flow-rate adjustment for nibbler and breaker modes, maintenance screens, self-diagnosis, service diagnosis modes 1 through 3, trouble history, and the maintenance schedule setting procedure.

Hydraulic System (61.6)

Three complete hydraulic circuit diagrams are reproduced for the demolition machine with common use type main boom: one for LMN rotation, one for separate boom with rotary N&B (basic jib cylinder), and one for separate boom with rotary N&B (large diameter jib cylinder). The circuit explanations walk through the neutral circuit, the hydraulic VLC travel circuit on the SK500DLC-8, the bucket circuit with stroke-end prevention, the boom circuit and holding valve, the jib circuit (raise and lower), the arm circuit with LMN/BH switching, the crusher rotation motor circuit, the crusher circuit, the breaker circuit, and the separate-boom neutral, arm and jib circuits. The hydraulic line drawing number list is included for cross-referencing to the parts manual.

Electrical System (61.7)

The electrical chapter reproduces the full circuit diagrams and then lists the electrical equipment with part numbers: mechatronic controller, cluster gauge, air conditioner, coolant level controller, auto grease controller, IT controller, engine controller, working lights, relays, diodes, and every sensor and switch on the demolition package. Harness lists follow, then the operator’s controls, controller installation, installment panel, upper electrical assembly, upper harness assemblies, cab install, boom harness assemblies, angle sensor installation, and stroke-end detection switch installation.

Components (61.8)

Component-level service data is grouped by assembly: the main hydraulic pump with its PTO gear pump for N&B rotation, the gear pump, relief valve, option control valve for the jib spec, selector valve, control valve for N&B rotation, pilot valves, solenoid valves (crusher rotation, arm in/out reverse, bucket protection, jib inverse proportional, hydraulic VLC), the separate jib H-side valve, the relief valve for the VLC retractable cylinder, the boom cylinder holding valve, and the full cylinder family — boom, LMN arm, LMN bucket, separate boom basic jib, separate boom large diameter jib, separate boom bucket, and SK500DLC-8 hydraulic retractable crawler cylinder.

Disassembly and Assembly (61.9–61.12)

This is the hands-on chapter. It opens with general precautions, slinging cautions and machine operation cautions, then goes step by step through removal and installation of the crusher, the arm, the inter boom, the front and insert booms, and the main boom on the ultra long attachment; the separate boom attachment procedure; the jib cylinder rod lubrication hose routing; bucket removal and installation with the clearance adjustment procedure; arm removal and installation; boom and boom cylinder removal and installation; and the complete cylinder disassembly, inspection, assembly, leak test, maintenance standards and special tool list. Counterweight installation and removal on the SK500DLC-8 stack type is included, as is the extension and retraction procedure for the SK500DLC-8 hydraulic adjustable crawler.

Troubleshooting, Safety Equipment and Automatic Lubrication (61.13–61.15)

The closing chapters cover the fault-finding matrix for LMN and separate boom configurations, the safety equipment list and the LMN/BH initial adjustment, and the automatic lubrication system — configuration, automatic and manual operation, controller keys and indicator codes, set items and setting procedure, normal operation display list, error list, automatic lubrication points for backhoe, 3-piece demolition and separate boom, cartridge replacement, air bleeding, and low/high temperature cautions.

IMAGES PREVIEW

The SK480DLC-8 and SK500DLC-8 demolition package is not a standard excavator with a long stick bolted on. The LMN attachment, the separate boom and the demolition backhoe each change the hydraulic routing, the electrical logic, the mechatronic control strategy and the structural load path. When a crusher stalls, when the arm runs backward after a connector swap, when the tip-over alarm stays silent, when the bucket stroke limiter refuses to release, the answer is usually in this section of the manual — in the pressure tables, the relief valve settings, the circuit diagrams, or the self-diagnosis screens. This PDF gives you the exact standard values, the test procedures, the diagnostic paths and the teardown sequences that the factory service literature uses. It is delivered as an instant PDF download after payment, with no shipping, no waiting, and the whole file works on any laptop, tablet or phone. Print the pages you need for the job and keep the rest on file.
