125/32 Ton Double Girder Overhead Crane

The 125/32 ton double girder overhead crane is a heavy-duty material handling system engineered for workshops and plants that must move large, high-mass loads with precision over wide spans. It features two independent hoisting mechanisms on a single trolley: a 125 t main hook for primary lifting and a 32 t auxiliary hook for secondary operations such as turning workpieces, positioning tooling, or handling lighter components. This dual-hook configuration lets a single crane cover both heavy and light tasks within one working cycle, cutting equipment costs and boosting shop-floor efficiency.

125/32 Ton Double Girder Overhead Crane

The crane is built on a box-type double girder structure with a fully enclosed trolley, delivering high rigidity, low deflection, and stable, shock-free travel even at full rated load. Every unit is assembled, aligned, and load-tested before leaving the factory to ensure reliable performance in continuous, round-the-clock operation.

125/32 Ton Double Girder Overhead Crane Technical Specifications

All parameters can be tailored to the actual span, headroom, and duty cycle of your workshop.

Key Features

• ◆ Dual-hook heavy-duty design — main and auxiliary hooks work independently, handling 125 t primary loads and 32 t auxiliary tasks in the same cycle.
• ◆ Box-type double girder structure — high rigidity and low deflection ensure precise positioning and stable lifting at full load.
• ◆ Stepless speed control — optional frequency-variable drives provide smooth acceleration and deceleration, reducing load sway and mechanical shock.
• ◆ Complete safety protection — overload protection, upper/lower limit switches, buffer stops, anti-sway devices, and emergency stop as standard.
• ◆ Flexible control options — cabin, pendant, or wireless remote control to match operating habits and site layout.
• ◆ Low maintenance — enclosed gear reducers and centralized lubrication cut daily upkeep and downtime.
• ◆ Adaptable configurations — explosion-proof, high-temperature, dust-proof, and corrosion-resistant versions available for special environments.

Quality & Compliance

The crane is designed, manufactured, and tested in accordance with international standards including ISO and GB, with full-load static and dynamic testing performed prior to delivery. Main structural components undergo strict weld inspection and surface treatment (shot blasting + primer/top coat), and complete technical documentation, drawings, and user manuals are supplied with every unit.

FAQ: 125/32 Ton Double Girder Overhead Crane

Q1: What is the difference between the main hook and the auxiliary hook?

A: The 125 t main hook handles primary heavy lifting, while the 32 t auxiliary hook is used for lighter loads, turning workpieces, or assisting setup work — allowing one crane to complete a wider range of tasks.

Q2: Can the span and lifting height be customized?

A: Yes. Span, lifting height, travel speeds, and power supply can all be engineered to match your workshop dimensions and site voltage.

Q3: Which working duty should I choose?

A: It depends on the frequency and intensity of use. A5 suits intermittent light-to-medium duty, A6 fits regular production, and A7 is recommended for continuous heavy-duty operation.

Q4: What control modes are available?

A: Cabin operation, pendant control, and wireless remote control are all available, and can be combined as needed.

Q5: Does it need special maintenance?

A: Routine checks of wire ropes, brakes, limit switches, and lubrication are sufficient; all key components are designed for easy access and long service life.
