Double Girder Overhead Crane 10 Ton S11.4m H6m Full VFD

The 11.4m span is matched to the 10m side column spacing for the following reasons:

• Column spacing: 10m — the distance between adjacent building columns along the workshop length
• Crane span: 11.4m — the runway rails sit on brackets attached to the columns, and the rail center-to-center distance is wider than the column spacing
• Runway beam brackets: Each rail is supported by a runway beam that extends beyond the column centerline, typically adding 0.5–0.7m per side
• Hook coverage: The 11.4m span ensures the trolley can reach across the full 10m column bay for complete hook coverage

In practice, the 11.4m span for 10m column spacing is a typical ratio for workshops where the runway beam is bolted to the column brackets. If your column spacing is different, the span will be re-calculated accordingly.

Full VFD means all three motions use variable frequency drives:

• Hoisting: 0.8 / 5.0 m/min — stepless control for precise load placement and smooth starts
• Trolley travel: 2.0 / 20.0 m/min — stepless control for smooth trolley movement along the bridge
• Long travel: 2.0 / 20.0 m/min — stepless control for smooth travel along the runway

Full VFD provides several benefits on this double girder overhead crane with crab wire rope hoist:

• Smooth acceleration and deceleration — eliminates shock loads on the load and structure
• Precise positioning — millimeter-level control for accurate load placement
• Reduced load sway — smoother motion reduces pendulum swing
• Energy savings — VFD matches motor speed to actual load, reducing power consumption
• Longer component life — less mechanical wear on gears, brakes, and wheels

A crab wire rope hoist is the standard hoisting mechanism for a 10t double girder overhead crane because:

• Higher rigidity: The crab frame distributes load evenly across the two girders, resisting bending at 10t capacity
• Higher hook lift: The crab runs on top of the two girders, so the hook can be raised closer to the bridge within the 6m lift height
• Better stability: The crab trolley runs on two rails (1400mm gauge), reducing load swing
• Higher duty capability: Crab wire rope hoists handle more cycles per hour than single girder hoists at the same capacity
• Easier maintenance: The crab design allows easier inspection and servicing of the hoist, motor, and brake

A single girder overhead crane is not typically used at 10t for continuous workshop duty — the double girder with crab wire rope hoist is the standard configuration.

Seven numbers on this double girder overhead crane with crab wire rope hoist drawing must match your workshop, or the crane will not fit or operate correctly:

If any of these seven differ from your workshop, tell Yuantai before ordering — each change affects price and lead time on the double girder overhead crane with crab wire rope hoist.

P30 rail is specified for this double girder overhead crane with crab wire rope hoist because:

• Wheel load: approx. 79.6 kN — the 10t capacity and 11.4m span create significant load moment at the end carriages
• Heavier double girder structure: The double girder bridge with crab wire rope hoist is heavier than a single girder crane, increasing the wheel load
• Full VFD smoothness: VFD reduces dynamic loads, but P30 is still required for the 79.6 kN wheel load
• Long service life: P30 rail is standard for 10t+ double girder overhead cranes in continuous workshop use
• Standard availability: P30 is a common rail section, easy to source and replace

Do not substitute a lighter rail (P22 or P24) without recalculating the wheel load and dynamic forces. The approx. 79.6 kN wheel load requires P30 or heavier.

No — this double girder overhead crane with crab wire rope hoist is configured for indoor workshop use. The full VFD overhead crane runs on elevated runway rails supported by the building structure, not on ground rails. Outdoor use would require:

• Different crane type — a gantry crane with ground rails and A-frame legs is more suitable for outdoor use
• Weather protection — outdoor electrical enclosures (IP55+) and anti-corrosion treatment
• Wind load design — anti-wind devices and anchoring for outdoor wind exposure

For outdoor applications, see the MHO 5t-7m A5 Siemens version with anti-wind and anti-toppling design, or the Long Travel Gantry Crane 5 Ton - S20m - H6m - 70m Runway for long outdoor corridors.

To avoid surprises at installation, these items are outside the double girder overhead crane with crab wire rope hoist supply scope unless you specifically add them:

• Runway rail (P30) and rail fasteners
• Runway beam and building column brackets
• Building structural support for the approx. 79.6 kN wheel load
• Site power supply up to the crane isolator
• Erection crane and site lifting equipment
• Local electrical connection and permits

Because the full VFD overhead crane runs on elevated runway rails supported by column brackets, the building structure and column bracket design are critical — the runway beam and brackets must support the approx. 79.6 kN wheel load and the dynamic forces from 2-20 m/min travel. Yuantai can provide runway load drawings as an optional item.
