Indoor Overhead Crane 10 Ton S16m H9m with Full VFD Dual-Speed

Full VFD dual-speed means that all three motions use variable frequency drive with two selectable speeds (fast / slow):

• Hoisting: 4 / 1 m/min — 4 m/min for fast lifting, 1 m/min for precise load placement
• Trolley travel: 16 / 4 m/min — 16 m/min for fast trolley movement, 4 m/min for precise positioning
• Crane travel: 30 / 8 m/min — 30 m/min for fast travel along the runway, 8 m/min for precise positioning

Compared with single-speed or dual-speed contactor-controlled cranes, full VFD dual-speed provides:

• Smooth acceleration and deceleration — no shock loading on the load or structure
• Two-speed flexibility — fast for long distances, slow for precision
• Reduced load sway — smoother motion reduces pendulum swing
• Energy savings — VFD matches motor speed to actual load
• Longer component life — less mechanical wear on gears, brakes, and wheels

4/1 rope reeving means the wire rope passes through a sheave system that creates a 4:1 mechanical advantage — four rope falls support the load. On this overhead crane:

• 4/1 reeving — the load is supported by four rope falls, quadrupling the lifting force and reducing individual rope tension
• φ14mm wire rope — a heavier rope diameter than 4/1 with smaller ropes, chosen for durability and high load capacity
• 6×36 Warrington-Seale construction — a wire rope design with 6 strands, 36 wires per strand, and Warrington-Seale construction for flexibility and fatigue resistance
• 200 kg/mm² rope grade — a high-tensile rope grade, providing higher breaking strength for the 10t capacity

Compared with 2/1 reeving:

• 4/1 reeving: Higher mechanical advantage, lower rope tension, longer rope life, but slower hook speed relative to drum speed
• 2/1 reeving: Lower mechanical advantage, higher rope tension, faster hook speed

The 4/1 reeving with φ14mm 6×36 Warrington-Seale rope is the right choice for high-cycle workshop operations where rope life and reliability matter most.

The 30 m/min crane travel speed and 16 m/min trolley travel speed on this high-throughput overhead crane are high-speed configurations designed for fast material handling cycles:

• Crane travel: 30 m/min — fast movement along the runway to serve multiple stations
• Trolley travel: 16 m/min — fast movement across the 16m span to position the hoist over specific workstations
• Hoisting: 4 m/min — fast hoisting for high-throughput handling, with 1 m/min slow speed for precise placement

Compared with standard overhead cranes:

• Standard overhead crane: 20 m/min crane travel, 10 m/min trolley travel
• This high-throughput crane: 30 m/min crane travel (+50%), 16 m/min trolley travel (+60%)

The higher speeds reduce handling cycle time in workshops where many lifts must be completed per shift. If your workshop has lower throughput requirements, standard speeds may be more economical.

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: The 10t capacity and 16m span create significant load moment at the end carriages
• High travel speed (30 m/min): Fast travel creates higher dynamic loads on the rail, requiring a heavier section
• Heavier double girder structure: The double girder bridge with crab wire rope hoist is heavier than a single girder crane
• 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 combination of 10t capacity, 16m span, and 30 m/min travel speed requires P30 or heavier.

No — this double girder overhead crane with crab wire rope hoist is configured for indoor workshop use. The full VFD dual-speed 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 reinforcement
• Building structural support for the 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 dual-speed overhead crane runs on elevated runway rails, the building structure is critical — the runway beam and columns must support the wheel load and the dynamic forces from 30 m/min travel. Yuantai can provide runway load drawings as an optional item.
