Bridge Crane for Precast Concrete Factory
The production efficiency of precast concrete factory mainly depends on the smoothness of component hoisting, material transfer and mold turnover.Bridge crane is the core heavy equipment of prefabricated workshop, which is suitable for demoulding, stacking and loading of various prefabricated components such as wallboard, beam column and box girder.Compared with ordinary equipment such as forklifts, special bridge cranes are more suitable for high-frequency, heavy-duty and high-precision operation scenarios in prefabricated plants, effectively solving common problems such as inefficient handling, component loss and potential safety hazards.
At present, many prefabricated factories generally have problems such as component shaking offset, slow material flow, high labor cost, easy equipment failure and so on, which seriously affect production capacity and production safety.This guide combines the actual working conditions of the prefabricated factory to explain the application value, selection points, efficient configuration and cost reduction scheme of the overhead crane in detail, helping practitioners to select products scientifically, standardize the use of equipment, avoid procurement and operation errors, and effectively improve the production efficiency of the workshop.
Why Precast Concrete Factories Need Bridge Cranes
Heavy component handling
Precast concrete members are generally heavy and bulky, and ordinary handling equipment cannot meet the heavy lifting requirements.Henan Mine Crane manufactured bridge crane for prefabricated factory supports 5 - 300 tons of load and is suitable for all kinds of components such as beam column, wall plate and box beam.The equipment adopts high-strength main beam and heavy winch structure, which is stable and not easy to deform. It supports single-point and double-machine synchronous hoisting, and can easily handle overweight, extra-long and extra-wide component operations. It is the core and efficient equipment for heavy load handling in prefabricated factories.
Faster material flow
Prefabricated production is an assembly line operation, and the material flow efficiency directly determines the production capacity.Bridge crane relies on the workshop top rail full coverage operation, no ground blind area, can complete the mold lifting, component displacement, demoulding transfer, finished product loading and other full process procedures.Compared with the short board with limited forklift operation range, it can quickly schedule across stations, speed up mold turnover, eliminate material accumulation and idle station problems, effectively open up production blocking points, and comprehensively improve workshop circulation efficiency.
Improved workplace safety
Heavy-load hoisting in prefabrication plant belongs to high-risk process, and manual auxiliary simple equipment has many hidden dangers.The special bridge crane is equipped with a complete set of safety systems such as overload limit, emergency braking, anti-swing, etc. to avoid the risks of lifting fall, overload, deviation, etc. from the source.The whole process of mechanized operation of equipment does not require manual close contact with heavy load areas, avoiding the problem of component collision with equipment and walls, greatly reducing the probability of safety accidents, and comprehensively improving the safety production level of workshops.
Reduced labor costs
The traditional prefabricated component hoisting needs many workers to work together, with large manual investment, low efficiency and high cost.Henan Mine Crane manufactured Intelligent bridge crane can realize single independent operation, greatly reducing the number of post workers.Equipment operation is simple, ordinary employees can be trained simply, reducing the cost of technician recruitment and training.At the same time, equipment operation and maintenance is convenient and stable, reducing manual maintenance investment, avoiding rework losses caused by operation errors, and saving the factory a lot of labor costs in the long run.
How to Select the Right Bridge Crane for Your Factory
Lifting capacity
Lifting tonnage is the core parameter of overhead crane selection, which is related to operation safety and production adaptability.The model selection shall be based on the maximum prefabricated component weight of the factory, superimposed with the weight of the lifting appliance, and reserve 10%-20% safety load margin to prevent the equipment from long-term overload operation.Small prefabricated components are suitable for medium and small tonnage models, box girders, large wall panels and other heavy-duty components, and large-tonnage double-beam cranes are required to be selected, giving consideration to equipment operation safety and procurement cost performance.
Crane span
Henan Mine Crane manufactured crane span is the center distance of the rails on both sides, which directly determines the coverage of equipment operation and needs to match the actual width of the prefabricated workshop.The span is too small to leave operation blind area, relying on manual auxiliary transportation.If the span is too large, it will increase the equipment cost, increase the running inertia and reduce the lifting accuracy.The normal span of prefabricated workshop is 12 - 36m, standard workshop adopts standard model, and ultra-wide and special-shaped workshop can customize non-standard span to ensure no blind area operation in the whole area.
Hook height
The lifting height of hook determines the maximum vertical height of lifting operation, which is suitable for core procedures such as demoulding, component stacking and high loading in prefabricated plant.The model selection shall be combined with the clearance height of the plant, mold size, component height and stacking layers, and sufficient safety margin shall be reserved to prevent the hook top rail and components from colliding with the top of the plant.Conventional workshop is suitable for lifting height of 6 - 18 meters, high workshop, multi-layer stacking operation scene, and can customize heightening models to meet the lifting requirements of the whole scene.
Product types
Bridge cranes are mainly divided into single beam and double beam, which can be flexibly selected according to production conditions.Single beam crane structure light, cost-effective, suitable for small and medium-sized components and medium frequency light load operation, suitable for small and medium-sized prefabricated factories.Double-beam crane has strong bearing capacity, high precision and working system up to A7-A8, which can meet the continuous production of high frequency and heavy load. It is the first choice for large component production.Special dust, corrosion conditions, but also customized explosion-proof, anti-corrosion special models.
Factory layout
The overall layout of workshop is the key basis for crane selection, which directly affects the installation effect and operation efficiency of equipment.Before selection, it is necessary to sort out the distribution of work stations, material circulation, finished product stacking and loading area layout. The dense work stations are suitable for high-precision double-beam cranes, and the narrow workshops are matched with customized stroke models.The large-scale partitioned workshop can be configured with multiple equipment for partitioned operation, and at the same time check the load bearing and track installation conditions of the workshop to ensure that the equipment is suitable for the site and does not occupy the ground production space.
Key Bridge Crane Features That Improve Production Efficiency
Anti-sway control
Precast concrete members are large in volume and inertia, and are easy to shake and deviate during lifting and movement, which not only reduces alignment efficiency, but also easily causes collision and damage of members, resulting in potential safety hazards.Henan Mine Crane manufactured bridge crane equipped with intelligent anti-swing control system can measure and correct the swing amplitude of the lifting object in real time, accurately suppress the vertical and horizontal two-way shaking, and make the component start and stop smoothly and accurately.Without manual auxiliary correction, it can not only improve the fine operation efficiency of demoulding and stacking, but also effectively reduce the damage loss of components and ensure the construction safety.
Variable speed drive
The traditional fixed-speed crane has large start-stop impact and fixed speed, which is difficult to meet the fine hoisting requirements of prefabricated components, and is prone to component deviation, mold collision and other problems.Variable frequency speed drive system supports stepless speed change free switching, long-distance transfer can run at high speed, save working hours, demoulding, alignment, loading process can be adjusted at low speed, smooth operation without impact.At the same time, it can reduce equipment start-up energy consumption and mechanical wear, prolong equipment service life, and give consideration to operation accuracy, efficiency and equipment operation stability.
Dual hoist design
Box girder, long beam column and other ultra-long prefabricated components, single-point lifting is easy to bear uneven force, resulting in bending, cracking, tilting and other scrap problems.Double hoist synchronous bridge crane equipped with double sets of linkage lifting mechanism, can achieve two-point synchronous lifting, translation, uniform distribution of component stress, from the root to avoid deformation damage.The equipment supports two modes of synchronous heavy load hoisting and independent light load operation. One machine has multiple uses and wide adaptability, effectively solving the hoisting problem of irregular strip members and significantly improving the qualified rate of finished products.
Remote operation
