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 the length of the side beam (including buffer)
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 the electric cabinet side cart track (change with H size)
 C2 - crane hook, the minimum distance from the center of electric cabinet side cart track (change with H size)
 H - crane orbit at the top of the distance from the top of the crane
 H - as crane hook rose to the highest point distance from the top of the crane
 W - cart wheel track beam

Single-girder crane girder structureSingle-girder crane beamSingle-girder crane hoisting mechanism

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, beam for rectangular steel tube production,2, the beam in the form of boring, a positioning processing using CNC boring and milling machine, ensure dimensional accuracy and tolerance;3, each beam is equipped with a double flange wheels, buffer 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. 5, beam material: S355J2G3 / EN10025 (Fe52D, equivalent to the Chinese standard 16 mn);

Lifting mechanism1, the unique C type low headroom structure, effectively improve the lifting space up to 1 m.2, the motor + reducer + + brake limit switch four unity integration design, compact structure3, lateral hung flexible drive system4, all transmission mechanism adopts direct input and output model of no coupling, high transmission efficiency, high assembly accuracy and free of maintenance. Level 5 and level of work for the A5, IP55 protection grade, class H insulation.Dustproof, waterproof, improve safety level.

Single-girder crane electric control systemElectronicElectronic control system: control system:

Single-girder crane safety monitoringSecuritySecurity Monitoring: Monitoring:
Safety monitoring:1, the built-in SaPro - intelligent security monitoring systemMonitor the crane malfunction2, can be calculated safety work cycleWorking hours, number of overload, etc3, is equipped with motor overheating, overload alarmThe thickness of the brake pad alarm, etc.4, by PLC in mobile-phone connection Timely monitoring information (custom)
Single-girder crane motorMotor :Motor :
Motor:1, squirrel cage type, double winding motor, electric chassis stamping molding by the aluminum tube2, IP55 protection grade, F class insulation, suitable for different complex environment.3, after electric continued rate 60%, ED, is 2.4 times that of the conventional motor4, the built-in thermistors overheating protection, advantages 5, direct drive output, speed 3000 RPM, high transmission efficiency Low carbon energy saving
Single-girder crane reducerGearbox :Gearbox :
Gearbox:1, Europe type crane dedicated reducer of compactSmall volume, light weight2, the material of the gear for nickel chromium molybdenum alloyAdopts the world famous brand antifriction bearing3, CNC automatic gear machining center productionThe hard tooth face (HRC60), through grinding processingFour and a half, grease lubrication, completely sealed Don't spill, free maintenance
Single-girder crane brakeBrake :Brake :
Brakes:1, the electromagnetic brake disc (adaptive), and motor coaxialBrake corresponding fast2, the brake pads life: normal use not less than 1 million timesEmergency braking is not lower than 5000 times3, often closed design, when the power is lifting mechanism in the braking stateTo ensure safety4, friction area is large, the brake torque is constant5, friction plate do not contain asbestos, environmental protection, whole sealing Dust proof, maintenance free
