Product introduction

Mr Walter bridge crane is a new generation of innovative products, superior performance, compact structure, light weight, safe, reliable and efficient operation, can satisfy all kinds of conditions.Mr Walter bridge crane is proposed, which can make customers reduce plant overall investment, improve the production efficiency, reduce the daily maintenance, save operation energy consumption, better return on investment.
Mr Walter bridge crane is widely used global well-known enterprises.Mr Walter heavy steady operation, quality first, pay attention to the concept of customer help to provide customers with safe and reliable products for a long time, let the customer of the material handling easier, create long-term value for our customers.
Crane as an important logistics equipment, production or fault caused by the loss is immeasurable.Mr Walter crane adhering to the consistent quality products, will be your best choice in the field of material handling.Mr Walter crane main product advantages as follows:

features
Compact structure, modular design, optimization of customer investment
Mr Walter crane with compact structure, light weight, small wheel pressure, such as uniform load distribution characteristics, so that customers can greatly reduce the construction cost, reduce heating costs, at the same time make the maintenance more convenient.Mr Walter compared with the other Chinese traditional crane, crane can fall on structure size space according to hoisting capacity, reduce the size of the between 10-50%, and the greater the lifting tonnage, a larger decrease, can achieve the optimization of customer comprehensive investment, a better return on investment.
Green concept throughout the entire design, save space and energy
Compact structure, resulting in the improved industrial production space;Parts were picked from sturdy and with crane life free maintenance parts, let the customer more at ease use;Reduce weight and wheel pressure decreases, the engine power is greatly reduced, let the whole crane in the manufacturing process, reduced the demand for raw materials, at the same time also let the customer in use process, greatly saves energy.
Safe and reliable, easy to maintain
Mr Walter with leading technology, advanced processing equipment, serial production and strict quality control to ensure that the crane reliable quality, excellent performance.We used in the design the design concept of maintenance free + easy maintenance, ensure that the product has the advantage at the same time, let the customer maintenance, easy to master.


Crane is shown in figure:
A - cart track center to the outside of the beam
)B - cart side beam of the wheel track (eight wheel)
C - as crane hook rose to the highest point distance from the electric hoist tractor wheel tread surface
C1 - crane hook the minimum distance from the center of on one side of the cart track
C2 - crane hook the minimum distance from the center of on one side of the cart track
D - crane hook rose to the highest point distance from the top of the crane
H - crane orbit at the top of the distance from the top of the crane
H - maximum height girders
K - two wheel track in the middle
W - cart beam's lateral wheel track
BK - cart the length of the side beam (including buffer)


Double beam crane girder structureDouble beam crane beamDouble beam crane trolley assembly

Main girder structure1, main girder used European box beam mechanism design, light weight, reasonable structure;2, the whole plate production, no butt weld, compete by girder more solid.3, vertical deflection is 1/800, web camber by nc cutting plate blanking, high precision.4, the use of automatic submerged arc welding, NDT.After welding the whole blasting, eliminate stress, derusting, achieve Sa2.5 level; 5, for Q235B steel material;Epoxy zinc-rich paint, the thickness of 120 microns.

Beam section1, large tonnage crane beam adopts flexible hinged design, avoid "three legs".2, the wheel adopt boring form, a positioning processing using CNC boring and milling machine, ensure dimensional accuracy and tolerance;3, each beam is equipped with double flange wheels, buffer, drive protection and anti cheat protection device, safety guarantee. 4, main girder and end beam with magnitude 10.9 high strength bolt connection, make sure the whole machine structure strength and precision.

The car assembly1, all the European design, effectively reduce the weight, increase the ascension space.2, the reducer with crane dedicated H series hardened tooth surface reducer, high carrying capacity, long service life.The spindle form 3, short drum USES the steel plate, and the weld NDT;4, pulleys are all made of hot-rolled pulley; Grade 5, hook used T hook, not below DG34CrMo, double row layout, save space;

Double beam crane electric control systemElectronicElectronic control system: control system:
Electrical control system:1, adopt schneider/chengtai export-oriented electrical components, imported typeWeidmuller relay switch, PLC programming control.2, big car for variable frequency infinitely adjustable-speed, inverter adopts the danfossHLP high-performance crane special vector frequency converter.3, the ceiling is a four breakpoint is adjustable, have speed limit, big car design for double breakpoint stop limit, safe and reliable.4, the whole machine design automatic reset function and overtime 2 times the vehicle running light load growth function, power supply and the anti-interference design are purification control device at the same time 5, there is the function of delay reset, 10 minutes after stop using when the equipment will automatically cut off power supply, avoid the safety hidden danger of miss operation.
Double beam crane operationOperatingOperating Mechanism: Mechanism:
Operation:1, the operation can adopt bo triad hard tooth surface reducer drive form, triad hanging on the beam lateral speed reducer, not affected by the car frame downwarping and vibration, improve the operation performance and life span, and compact structure, beautiful appearance, easy installation and maintenance.2, wheel with 42 crmo alloy forging wheel, high strength wear resistant, long service life.3, bearing choose authentic tiles, ha, los products; 4, wheels adopt boring type installation, a positioning;
Double beam crane limit switchLimitLimit Switch : Switch :
Limit switch:1, the ceiling is a CAM rotary level 4 limit switch, eliminate hidden dangers in summit2, adjustable up and down limit position 4 points, before the braking deceleration, programmable Settings3, big, the car limit adopt cross fork limit, stable performance 4, speed limit function can slow down after the stop, stop smoothly.
Double beam crane power supply systemPower supplyPower supply System : System :
Power supply system:1, wuxi unipolar slide wire, high electrical conductivity, small pressure drop, duty rate is as high as 80%,2, the built-in cable wire, strong resistance to drag force3, pick wire frame adopts C rail, solid, smooth 4, special customized cable, high temperature resistance, corrosion resistance, ageing resistance
