Safety Precautions and Warnings

Sets out the required operator knowledge, permissible operating conditions, maximum load rules, preparation for use, outrigger leg handling, electrical line clearance distances (tabulated by voltage for insulated and uninsulated conductors), driving with the crane, demountable crane use, maintenance and service restrictions, fault handling, and warranty conditions. Includes the minimum-distance table for overhead electricity lines from 40000 V.

Structure and Parts of the Crane

Describes the main groups: crane base and column with slewing system (three-point bridge, single rack and pinion), boom system (inner boom, outer boom, hydraulic extension boom, manual extensions, jib), outrigger leg system (fixed and extendable versions), and the operating system (hydraulic oil, oil tank, pump, control valves, cylinders, filters). Includes component identification illustrations and control lever symbol diagrams.

General Instructions for Use

Explains lifting capacity (load moment), how to read the load plate and load diagram, operating positions, strop length rules (max 120° angle between sling legs, with mode factor table for two-, three- and four-legged slings), lifting technique for heavy loads and loads at the working zone limit, and working below ground level.

Technical Description

Provides the JG7000 3.5M specifications: 0.8 ton-m lifting capacity, 3.5 m max working radius, 300 kg at 2.6 m and 210 kg at 3.5 m outreach, 120 bar working pressure, 15 l/min rated oil flow, 1 m/sec lifting speed, -40° to 61° boom angle, 330° slewing angle at 20°/sec, single rack gear slewing type, and 280 kg weight without outrigger. Includes outline views, lifting capacity chart, and full hydraulic diagram with relief valve pressure settings marked per port.

Operation

Covers pre-operation checks, PTO engagement and engine speed guidance, cold-weather warm-up procedure (do not touch levers for the first few minutes below 0 °C), driving after operation, and safety instructions during operation (oil temperature limits, load handling rules, outrigger verification, no dragging loads, no slewing at full speed to final position).

Preventive Service & Maintenance

Contains daily inspection tables, inspection points during and after operation, one-month and six-month maintenance schedules, lubrication schedule with recommended greases, hydraulic oil checking and changing procedures, filter insert replacement (return filter, pilot filter, high-pressure filter — first change at 50 hours, then every 500 hours or twice yearly), and hydraulic leakage handling.

Faults & Troubleshooting

Lists faults the operator may rectify, with probable causes and actions — hydraulic pump noise (blocked tank filter cap, low oil level, defective pump), irregular slewing movement, add-on equipment faults, and hydraulic leaks. Clearly marks which faults require a HIAB service workshop.

Spare Parts List

An illustrated parts catalogue covering the total assembly (Backward and Frontward Slewing Stop versions), base assembly, slewing pipe kit, column assembly, 1st and 2nd cylinder assemblies, inner and outer boom cylinders, 1st and 2nd boom assemblies, 1st and 2nd boom hose kits, column hose kit, control system, main control valve, sticker arrangements, and shaft assemblies. Each diagram is followed by a part-number table with description, quantity, and remarks.

Appendices

Appendix 1 provides the Beaufort wind speed scale with operating limits (crane must not be used when mean wind velocity exceeds 13.3 m/sec). Appendix 2 documents the standard hand signals for crane operation: lift, lower, stop, emergency stop, short movement, change reach, turn, grapple open/close, and hold.

Why This HIAB JG7000 Manual Matters

Whether you operate a HIAB JG7000 3.5M daily, service one in a workshop, or need to order the correct replacement parts for a Backward or Frontward Slewing Stop configuration, this manual provides the procedures and specifications published for the crane. The load charts, hydraulic diagram with relief valve pressure settings, maintenance intervals, and the complete illustrated parts list with part numbers are all here in one document.

The operator’s section covers the tasks that keep the crane safe and within warranty: outrigger setup on firm ground, maintaining electrical clearance from overhead lines, cold-weather warm-up, correct strop angles, and the daily, monthly, and six-month inspection schedules. The troubleshooting tables identify the faults you can handle yourself and clearly mark which require a HIAB service workshop.
