A carry deck crane is a compact, self-propelled mobile crane built on a low, flat deck, with a center-mounted telescoping boom that rotates 360 degrees. This carry deck crane guide explains how that geometry works, how to size a unit, and why the load you can carry while driving differs from the load you can lift while parked. Size the machine from the manufacturer's load chart at your working radius first. Then confirm three things:
A carry deck crane is a compact mobile crane with a center-mounted boom and a flat deck for moving material within a work area. Its central turntable lets the operator work around the carrier, set a load on the deck, and relocate material within chart limits. You can review carry deck and industrial crane listings on Crane Network.
The boom sits on a turntable in the middle of the frame, usually between a front deck and a rear deck. Typical designs pair that center-mounted boom with continuous 360-degree rotation and a low overall profile. Continuous rotation lets the operator work on any side without repositioning the carrier. Some models also offer four-wheel or crab steering for narrow aisles. Confirm steering modes, stowed height, and clearance dimensions in the specifications for the exact unit.
Static lift capacity is the parked lifting rating under the setup stated in the manufacturer chart, such as an outrigger or on-rubber configuration, at a given radius and boom length. Pick-and-carry capacity is the separate rating, where provided, for traveling with a suspended load. It is commonly the lower of the two numbers, because turns, braking, surface changes, and tire deflection all affect stability.
The applicable manufacturer chart states the permitted boom position, boom length, load height, travel direction, surface, and speed for any suspended-load travel. A crane's ability to rotate 360 degrees does not mean it can travel with a suspended load in every direction. Leave final lift planning to the manufacturer documentation and a qualified lift director.
| Rating | Static lift (parked) | Pick-and-carry (traveling) | Deck transport rating |
| What it covers | Hoisting while parked | Driving with the load on the hook | Material resting on the deck |
| Conditions to confirm | Setup stated in the chart, radius, boom length, quadrant of operation | Boom position and length, load height, surface, travel speed | Rated deck position, placement, securement, and overhang limits |
| What to check | Radius at the far end of the pick, not just the start | Tire condition and inflation, route grade, floor joints and thresholds | Deck plate condition, tie-down points, combined axle loading |
| Rating | What it covers | Conditions to confirm | What to check |

Carry deck cranes can suit indoor crane lifting and tight-access work, because a compact layout and low stowed profile may help a unit fit through constrained routes. Confirm dimensions for the exact model, and measure the lowest point along the whole travel route, not just the entry door.
Indoor work adds constraints a yard job does not have. Confirm the floor slab or mezzanine rating against the machine's wheel loads and any outrigger pad pressure, because concentrated ground bearing pressure under a pad can exceed a slab limit that the gross machine weight suggests is fine. For enclosed work, confirm the site's ventilation and emissions requirements and verify the unit's engine configuration with the seller or rental provider.
Size a tight-access unit from the total lifted load, the governing radius, the required hook height, the travel method, and the route dimensions. Parked lifting, hook travel, and deck transport can each use a different rating.
Consider a hypothetical lift involving a pump skid weighing 6,800 lb and rigging weighing 400 lb. The combined weight is 7,200 lb, before the hook block and any other load-handling attachments required by the chart. At an 18-foot working radius, the crane must have enough rated capacity at that radius in the planned configuration. These figures are illustrative only.
The flat deck is a transport surface with its own rating, and it is easy to overload because it looks like an ordinary flatbed. Before you load it, verify the items below with the operator manual for that serial number.
On a used purchase, deck and frame condition is also a valuation signal. Heavy deck wear suggests the machine hauled material regularly, so inspect the turntable bearing, boom wear pads, wire rope, and hydraulic cylinders with the same attention. Resale values across this class vary with operating hours, maintenance records, boom and wear-pad condition, model year, emissions tier, and location, so treat any single asking price as one data point.
Carry deck crane uses cluster around plant turnaround and maintenance work, where crews move components through congested areas with limited overhead room. These machines suit short-distance handling of maintenance materials when the required radius, route, floor support, and deck rating fit the job. Typical tasks include:
If the work is outdoors with long reach, higher tip height, and highway travel between sites, review the boom truck crane category alongside compact units to compare sizes and configurations.
They overlap but are not identical. Pick-and-carry describes the ability to travel with a suspended load, which several crane types share. A carry deck crane is a specific compact class with a flat deck, center-mounted boom, and full rotation built for that duty.
Not necessarily. Check the unit's manufacturer load chart to see whether it permits a lift on rubber and under what conditions. If an outrigger configuration is listed, its rating may differ from the on-rubber rating. Follow the chart for that unit.
That depends entirely on the model and the lift. You need clearance for the stowed boom while traveling, plus enough height at the pick point for the boom angle, hook block, and rigging above the load. Measure the lowest obstruction along the full route.
Only if the manufacturer allows it for that model, and within stated limits. Deck loads and hook loads both affect stability and axle loading. Check the operator manual before combining them, and have a qualified lift director confirm the plan.
Compare expected annual hours against ownership costs. Industrial crane rental often suits a single outage window, while plants running frequent maintenance moves year-round may justify ownership. Factor in mobilization, storage, operator availability, maintenance, and the unit's likely resale value.
Start with the turntable bearing, boom wear pads and sections, wire rope, hook block, hydraulic cylinders, and deck plate. Then review hour meters, service logs, and recent inspection reports. For a higher-hour machine, consider a third-party pre-purchase inspection.
Use this carry deck crane guide when you need to move heavy components through doorways, under pipe racks, and across congested plant floors. Size the machine from the governing radius, verify the travel and deck ratings separately, and walk the route before you commit. Those checks surface fit, route, and rating constraints before turnaround work begins.
