All-terrain crane

01

Read capacity from the load chart, boom and reeving

Liebherr's LTM 1150-5.3 technical data gives a 217 ft (66 m) telescopic boom extendable from 40 ft in about 460 seconds, a boom raise to 83° in about 57 seconds, slewing at 0–1.5 rpm, and two winches with 0–367 ft/min single-line speed, 21 mm rope, 820 ft rope length and 20,590 lb permissible single-line pull. Lifting capacities are given in load charts for each boom length, radius, counterweight and wind speed. Hook blocks range from 257,700 lb with 7 sheaves and 14 lines down to a 20,300 lb single-line hook. [1]

Editorial calculation: 257,700 lb divided by the 20,590 lb rope pull needs at least 12.5, so 13 or more parts of line; the 14-line block gives margin. Capacity falls steeply with radius and boom length, so plan each lift from the load chart at its actual radius, boom length and counterweight, not from the crane's class. [1]

Grove's GMK5150L-1 product guide (150 t class) gives a 12.8–60.0 m six-section boom telescoped in approx. 400 s, boom elevation from −1.5° to +83° in approx. 48 s, slewing at 0–1.5 rpm, and a main hoist with 19 mm × 255 m rope, 0–120 m/min single-line speed and 84.0 kN maximum single-line pull. Its heaviest hook block is 140 t with 8 sheaves, weighs 1,600 kg and reeves 2–17 lines; capacities above 98 t need additional equipment and above 130 t special equipment. At the full 60 m boom it quotes 11.8 t. [2]

Editorial calculation: 140 t × 9.81 m/s² ≈ 1,373 kN; divided by the 84.0 kN rope pull that needs at least 16.3, so 17 parts of line, the top of the 2–17 range Grove lists. The 11.8 t at 60 m is about 8% of the 150 t class, which is why the class says little about a long-boom lift. [2]

Tadano's AC 3.060-2 data sheet (65 US ton class, marked preliminary, September 2026) gives a boom up to 164.0 ft telescoped in approx. 450 s, boom elevation from −5° to 82° in approx. 35 s, 15,040 lbf maximum line pull on 0.72 in rope, 656 ft rope length and 354 ft/min hoist speed; three sheaves in the boom head give a maximum of 87,100 lb. [3]

Editorial note: compare suppliers' cranes using load charts for the same boom length, radius, counterweight and wind speed.

Give the supplier the heaviest lift with its weight, rigging and required radius and hook height, other lifts, site access and road route limits, allowable axle loads, ground bearing capacity and mats, wind conditions, operating hours, jib or extension needs, emissions and quantities or rental duration.

02

Check axle loads, outrigger forces, travel and gradeability

The data sheet gives on-road axle loads of no more than 22,050 lb (10 t) or 26,450 lb (12 t) depending on configuration, maximum counterweight of 99,200 lb, maximum outrigger supporting forces of 159,000 lb and 197,000 lb in the two outrigger positions shown, a top speed of 53 mph and a theoretical gradeability of 56.5% on 445/95 R25 or 525/80 R25 tyres, and a 400 kW engine. [1]

Editorial calculation: 26,450 lb is 12.0 t and 22,050 lb is 10.0 t; 99,200 lb of counterweight is 45 t; 197,000 lb is about 89.4 t (876 kN) on one outrigger, so a 1 m² mat would impose about 876 kPa and a 4 m² mat about 219 kPa. Size outrigger mats from the supplier's actual outrigger loads for your lifts and the ground's allowable bearing pressure. [1]

Grove lists 44.5 t of counterweight in sections, of which 30.9 t stays within a 2.75 m vehicle width, and configurations from 1 t of counterweight on the crane up to taxi configurations of 12 t to 16.5 t per axle; the data page shows maximum supporting forces of 64.6 t and 74.2 t. The carrier has a 10 × 6 × 10 drive with all five axle lines steered, a 390 kW engine to EUROMOT 5 / EPA Tier 4 final and 325 l + 325 l of fuel. [2]

Tadano's three-axle AC 3.060-2 lists axle loads below 26,500 lb (total below 79,400 lb) with 9,300 lb of counterweight on board, rising to below 35,300 lb per axle (total below 105,800 lb) with 28,700 lb; it offers three outrigger bases of 9.8 ft, 14.8 ft and 21.3 ft, a 260 kW engine to EU Stage V/Tier 4F, and 52.8 mph depending on tyres and national legislation. [3]

Editorial calculation: Grove's 74.2 t is about 728 kN on one outrigger, about 728 kPa on a 1 m² mat; Tadano's 35,300 lb per axle is about 16.0 t, against about 12.0 t for the 26,500 lb configuration, so check the route's axle limit for each counterweight carried. [2] [3]

Editorial note: road permits depend on axle loads and overall dimensions in the travel configuration; ask which counterweight and equipment can travel with the crane and which must follow on a separate truck.

03

Read the rating basis: EN 13000, ASME B30.5, ISO 4305 and wind

EN 13000:2010+A1:2014 applies to the design, construction, installation of safety devices, information for use, maintenance and testing of mobile cranes as defined in ISO 4306-2. It excludes loader cranes (EN 12999), offshore cranes (EN 13852-1), floating cranes (EN 13852-2), variable reach trucks (EN 1459), mobile self-erecting tower cranes and earth-moving machinery used for object handling, and does not cover hazards related to lifting persons. It covers cranes designed for a limited number of stress cycles and loading conditions to ISO 4301-2:1985 group A1; grab, magnet or similar duty needs additional provisions outside its scope. The Estonian edition lists it as valid from 05.06.2014 under Machinery Directive 2006/42/EC. [4]

Liebherr states that the LTM 1150-5.3 lifting capacities do not exceed 85% of the tipping load according to ASME B30.5, and that the structural steelwork is in accordance with EN 13000 and ASME B30.5. Its load charts assume a wind speed of at least 9 m/s (20 mph), a sail area of 1 m² per tonne of load and a wind resistance coefficient of 1.2; loads with larger sail areas need a lower maximum wind speed. Hook blocks and hooks are part of the load and must be deducted, radii are measured from the slewing centre, and telescopic-boom capacities apply with the folding jib removed. [1]

Grove states that the GMK5150L-1 capacities correspond to EN 13000:2010 and fulfil ISO 4305 for stability, and defines lifting capacity as payload plus the weight of the hook block and suspending device. Tadano states that the AC 3.060-2 ratings comply with ASME B30.5 and do not exceed 85% of tipping load, and that its IC-1 load moment indicator works in accordance with EN 13000. [2] [3]

Editorial calculation: a rating at no more than 85% of tipping load means the tipping load is at least 1 ÷ 0.85 ≈ 1.18 times the chart value. The 1 m² per tonne wind assumption means a 10 t load with a 25 m² face exceeds the 10 m² the chart allowed for, so the permitted wind speed must come down. [1]

Editorial note: ask each supplier which standard its charts are calculated to and the wind and sail-area basis, and compare cranes only on charts with the same basis.

Meet OSHA 29 CFR 1926 Subpart CC on US construction sites

Under 29 CFR 1926.1402 equipment must not be assembled or used unless the ground is firm, drained and graded enough that, with supporting materials (blocking, mats, cribbing) if necessary, the manufacturer's specifications for support and level are met. The controlling entity must provide the ground preparation and tell the user and operator about hazards beneath the set-up area, such as voids, tanks and utilities, that it knows of. [5]

Section 1926.1415 requires a crane level indicator, boom stops (except on hydraulic booms), jib stops when a jib is attached, a horn, and an integral holding device or check valve on hydraulic outrigger jacks; operations must not begin unless these work. Section 1926.1416 requires an anti two-block device on telescopic-boom cranes made after February 28, 1992; a load weighing device, load moment indicator or rated capacity limiter on equipment made after March 29, 2003 rated over 6,000 lb; a boom angle or radius indicator and, for telescopic booms, a boom length indicator; and, on equipment made after November 8, 2011, an outrigger position sensor and a hoist drum rotation indicator where the drum is not visible. Category I aids must be repaired within 7 calendar days and Category II within 30. [5]

Section 1926.1408 applies to power lines up to 350 kV: if any part of the crane, load line or load could come closer than 20 feet when operated to its maximum working radius, the employer must de-energize and ground the line, keep 20 ft, or keep the Table A distance. Table A sets 10 ft up to 50 kV, 15 ft over 50 to 200 kV, 20 ft over 200 to 350 kV, 25 ft over 350 to 500 kV, 35 ft over 500 to 750 kV and 45 ft over 750 to 1,000 kV. [5]

The data sheets show matching devices: Grove lists a load moment and independent anti-two-block system and a drum rotation indicator, and Tadano lists individual outrigger stroke monitoring, an outrigger load indicator and a hoist rotation indicator. [2] [3]

Editorial calculation: 6,000 lb is about 2.7 t and 20 ft is about 6.1 m, so the working radius used to check power-line clearance must include the swing of the load and rigging. [5]
