Approved Code of Practice for Cranes
Part 14: Truck loader type cranes (including knuckle boom and telescopic/straight boom)
14.1 General
Truck loader type cranes (including knuckle boom and telescopic/straight boom) require design verification by an inspection body in accordance with the PECPR Regulations and Parts 2 and 6 of this code, prior to certification for use within New Zealand. This requirement does not apply to truck loader type cranes of lifting capacity less than 0.9 tonne metres (t-m)[1].
Parts 3, 4, 7, 8 and 9 of this code also apply.
A supplier, manufacturer or controller of such a crane shall provide the documentation specified in Part 6 to the inspection body carrying out the design verification.
(1) For minimum load safety device requirements required on the various crane types, refer to Appendix A: Load Safety Devices/Safe Load Indicators.
(2) For minimum load safety device and inspection requirements (including transitional requirements) for this class of crane, refer to Appendix A.
14.2 Additional Requirements
In addition to the requirements in Part 14.1 and Part 3: Operational Requirements for Controllers, the following are also required:
(1) Suppliers shall provide:
(a) manufacturer's rating chart
(b) manufacturer's recommended installation instructions
(c) operating and maintenance instructions in English
(d) hook certificate
(e) hook block, sheave block and wire rope certificates, where appropriate.
(2) Before putting a crane into service, there shall be:
(a) In the case of cranes mounted to road vehicles requiring a Certificate of Fitness, a certificate from a New Zealand Transport Authority - approved HVEC engineer to certify that the crane installation/vehicle modification complies with the crane/vehicle manufacturer's recommendations as specified in appropriate land transport rules[2]. This must include an assessment of suitability of the mounting to include crane loadings due to transport and operation under the crane's maximum safe working load.
Note: This Rule should be read in conjunction with Land Transport Rule: Heavy Vehicles 2004 and subsequent amendments.
(b) a certificate of inspection from an inspection body before first use as a crane
(c) a stability test demonstrating the stability of the vehicle with the crane at maximum load for any given radius with the crane boom at minimum operating angle and the vehicle on level ground in accordance with the crane manufacturer's recommendations. If the manufacturer's recommendations are not available then the requirements of AS1418.11 Cranes Hoists and Winches: Vehicle-Loading Cranes clause 2.7.3 "Stability" must be met.
The stability test shall be conducted as per clause 3.2.5 of AS1418.11. When testing stability to AS 1418:11 clause 3.2.5, up to half the wheel sets in only one axle group may lose contact with the ground. At least half the individually braked wheel sets shall stay in contact with the ground
(d) a note in the form of an approved load chart on the crane where it is visible to the operator describing any area of potential instability and operating limitations of the crane.
14.3 Inspections
(1) Annual visual and operational inspections by an equipment inspector or competent person as appropriate[3] (refer to Appendix A: Load Safety Devices/Safe Load Indicators) are required to assess the general condition for continued safe operation and certification. This should cover (but is not limited to):
(a) all boom and extension pins and bushes
(b) stabiliser beams, pins and leg operation. A vehicle fitted with outriggers must either have a locking device that is able to be seen in a locked position when the outriggers are retracted, or a visual or audible alarm for the operator to be warned that the outriggers are not fully retracted
(c) extension cylinder guide blocks
(d) control rods and pins
(e) hook pin and safety latch
(f) valve bank mounting
(g) tank mounting
(h) hydraulic hoses
(i) slew ring or post
(j) crane to truck chassis mounting
(k) demount mechanism on mounting and crane
(l) crane base stop blocks fitted to both sides of main beam
(m) chassis spacer fitted on mounting bolts
(n) mounting bolts tight (secured with locknuts or self-locking fasteners)
(o) load radius rating chart affixed
(p) parking bolt and parking mount
(q) operation of overload protection systems and load holding valves
(r) electrical emergency stop and radio compliance
(s) crane documentation including certified rating sheets marked with crane unique identifier and serial number
(t) maintenance and repair records including any new rope certificate
(u) general condition of crane structure, fastenings and chassis
(v) coatings condition (paint etc.), markings and labels
(w) condition of welded joints
(x) winch, sheaves, hook block and bearings (where fitted)
(y) condition of hoist ropes (where fitted)
(z) rope anchors and dead ends (where fitted)
(aa) hook block and swivel bearing
(bb) jib
(cc) manual extension
(dd) remote/radio controls to be tested, where applicable
(2) 0 - 0.9-t-m cranes shall:
(a) comply with 14.1, 14.2 and all parts of 14.3 except 14.3(3)
(b) have the initial inspection by an equipment inspector and subsequent annual inspections may be carried out by a competent person. Refer to Appendix A.
(3) All cranes over 0.9 t-m shall:
(a) comply with 14.1, 14.2 and all parts of 14.3 except 14.3(2)
(b) if remote- or lever-controlled crane, have an emergency cut-off/reset button at each operating control station
(c) be fitted with load holding valves on main, outer and extension booms
(d) be fitted with a pilot-controlled double-check valve or a manual check/isolating valve on each stabiliser jack
(e) have an annual inspection carried out by an equipment inspector. Refer to Appendix A.
(4) All certificates of inspection must be placed and visible in the vehicle cab (or on the crane, for non-vehicular applications).
(5) When moving on the road, the crane boom must be either located in or on the parking mount if provided, or located or locked in a position such that the boom is secured within the vehicle dimensions.
Footnotes
[1] “Tonne-metre capacity” is the minimum radius at which the crane can lift a load multiplied by the SWL in tonnes at
that radius.
[2] Where a truck loader type crane is not fitted to a heavy motor vehicle, this certificate is not required. A CPEng certificate for the installation may be required by the inspection body depending on the application. Likewise, a stability test may not be required/appropriate for non-vehicular applications.
[3] Inspections by a competent person must be documented in a register held by the owner.
