32/10 Ton Double Girder Overhead Crane

The 32/10 ton double girder overhead crane (Model: QD32/10) is a heavy-duty bridge crane designed for reliable, high-efficiency material handling in workshops, warehouses, and production plants. It features a twin-hook design: a 32t main hook for heavy lifting and a 10t auxiliary hook for light and fast handling of smaller loads — allowing operators to switch between heavy and light duty without changing equipment. The box-type double girder structure provides high rigidity, excellent load-bearing capacity, and stable operation, making it an ideal lifting solution for steel plants, machinery workshops, assembly lines, and other industrial applications.

32/10 Ton Double Girder Overhead Crane Key Features

• ◆ Twin-hook design — 32t main hoist + 10t auxiliary hoist, each with an independent drive mechanism, maximizing working flexibility and efficiency
• ◆ Double girder box structure — high rigidity, less deformation under heavy load, smooth and stable crane travel
• ◆ Independent hoisting mechanisms — main and auxiliary hooks can be operated separately or in coordination for multi-task lifting
• ◆ Multiple control options — floor pendant, wireless remote control, or cabin operation available
• ◆ Variable frequency drive (VFD, optional) — soft start/soft stop, stepless speed control, reduced load swing and mechanical impact
• ◆ Complete safety protection — overload limiter, limit switches, emergency stop, and motor overload protection
• ◆ Long service life — forged wheels, high-strength steel girders, welds tested by X-ray and ultrasound
• ◆ Standard-compliant — designed and manufactured in accordance with GB/T 3811, FEM, ISO, and CMAA standards

Technical Specifications (Typical)

Note: All parameters are typical values and can be customized according to your working conditions.

Structure & Main Components

• ◆ Bridge frame — two box-type main girders rigidly connected to the end carriages; the bridge can be split into two sections for convenient transportation and installation.
• ◆ Trolley — consists of the trolley frame, main hoisting mechanism (32t), auxiliary hoisting mechanism (10t), and trolley traveling mechanism.
• ◆ Hoisting mechanism — wire rope hoist with electric motor, reducer, drum, and hook block; equipped with DC disc brake (safety factor ≥ 1.8) for reliable braking.
• ◆ End carriages — driven by independent traveling mechanisms with forged wheels, providing stable and quiet movement along the runway rails.
• ◆ Power supply system — sliding conductor rail (bus bar) or cable trolley, with protection board for safety.
• ◆ Control system — control panel with IP54 protection, safe and easy access for inspection and maintenance.

Safety Protection System

• ◆ Overload limiter — warning alarm at 90% of rated load; automatically cuts off the lifting power at over 105% rated load
• ◆ Limit switches — hoisting upper/lower limits, trolley travel limits, and crane travel limits
• ◆ Emergency stop system — one-press power-off for emergency situations
• ◆ Buffers & anti-collision devices — absorb impact at end positions
• ◆ Track sweep plates & shields — prevent debris and personnel injury
• ◆ Electrical protection — short-circuit protection, no-voltage protection, ground protection, and motor overload protection
• ◆ Audible & visual warning — horn and indicator light for safe operation

Quality Assurance & Customization

Every crane is manufactured with strict quality control: main welds use qualified welding processes with non-destructive testing, all electrical components are from reputable brands, and each unit undergoes full load testing before delivery.

We offer full customization — span, lifting height, lifting speed, working duty, control mode, voltage, and rail system can all be designed to meet your specific site conditions.

FAQ — 32/10 Ton Double Girder Overhead Crane

Q1: Can the span and lifting height be customized?

A1: Yes. Standard span ranges from 10.5 m to 31.5 m and lifting height from 6 m to 24 m, but both can be designed to fit your specific workshop dimensions and working requirements.

Q2: What control options are available?

A2: Three options: floor pendant control, wireless remote control, and cabin (operator cab) operation. The most suitable mode depends on your working environment and lifting frequency.

Q3: Which standards does the crane comply with?

A3: The crane is designed and manufactured in accordance with GB/T 3811 (China), FEM (Europe), ISO, and CMAA standards. Certification such as CE and ISO 9001 can be provided on request.

Q4: What safety devices are included?

A4: Standard safety package: overload limiter (alarm at 90%, power cut at 105% of rated load), lifting and travel limit switches, emergency stop, buffers, track sweep plates, and motor overload / no-voltage / short-circuit electrical protection.

Q5: What is the power supply requirement?

A5: Standard supply is 380V / 50Hz / 3-phase, and the control voltage is 36V for safety. Other voltages (e.g., 220V, 415V, 460V, 60Hz) can be arranged according to your local grid.

Q6: How is the crane delivered and installed?

A6: The bridge is split into sections for container-friendly transport. Our engineers provide installation drawings, on-site supervision (optional), and commissioning guidance. A full load test is carried out before delivery.

Q7: What about warranty and after-sales service?

A7: The crane comes with a standard warranty (typically 12–24 months) on mechanical and electrical parts, plus long-term supply of spare parts and lifetime technical support.
