QB Model Explosion Proof Double Girder Overhead Crane
Description:
QB model Explosion proof double girder overhead crane is suitable
for workshops and warehouses with inflammable and explosive
mixtures. It relies on the longitudinal movement along the
direction of the workshop track, the lateral movement of the
trolley and the lifting movement of the hook to work. This machine
is suitable for mechanical processing and assembly workshops, metal
structure workshops, mechanical maintenance workshops, metallurgy
and foundry workshops, and hoisting work in various warehouses.
Features:
- The bridge adopts box-shaped main beam, which is automatically
welded by submerged arc welding.
- The trolley adopts a new I-beam track cable conduction device,
which is safe and reliable.
- The hoisting mechanism can also be equipped with a second set of
safety devices as required to increase reliability.
- Standardization, serialization and generalization of parts and
components.
- The operating field of vision is wide, and all the mechanisms are
operated in the operating room, which is comfortable and flexible.
- Steel Material: Chinese standard Q235B and Q345B
- Trolley rail is made of high strength hot rolled flat steel (16
Mn).
- Epoxy zinc-rich painting for one bottoms and two sides of 120μm
thick, to achieve a long lifespan, beautiful appearance and good
luster.
- The girder and end beam are connected together by high strength
bolts to ensure the structure strength and precision of the whole
machine.The end beams are equipped with flat wheel or double rim
wheels, anti-friction bearings, buffer blocks and derailment
preventing end plate.
- Maintenance walkway is located on one side of the main girder,
consisting of flower pattern plate, 1050meters handrail.
- Applied to explosion transfer capacity no higher than the II B or
II C-class and the sites with explosive air mixture formed with
inflammable gas (or steam) and air whose factory ignition
temperature groups between T1 group and T4 group. The applicable
hazardous area: 1 division or 2 division. The working duty:A5~A8.
- It is widely used in the loading, unloading and handling of
ordinary heavy objects. It can also be equipped with a variety of
special spreaders for special operations. When used in the open
air, it has rainproof equipment.
