The lifting capacity of ZX6 gourd is 0.5-5t, The lifting capacity range of ZX8 is 1-25 tons. The tonnage of the ZX series will continue to be extended to 50t, with all commonly used tonnages equipped with M5 working system, and the vast majority of tonnages equipped with M6 or M7 working system. ZX6, The 8-gourd design has three basic structural dimensions, each of which provides multiple motor powers, gearbox speed ratios, drum lengths, and wire rope winding options.

The design of ZX gourd components minimizes the operating limit of the hook to the greatest extent possible, effectively improving the utilization of factory space and minimizing the construction cost of the factory. The working environment temperature of gourds is -10 ℃ -40 ℃, and there are special models that are suitable for environments above 50 ℃. All exposed parts of the gourd are protected by epoxy polyester powder coating or chromate passivation surface, which can effectively resist corrosion.

The lifting motor largely determines the performance and lifting capacity of the hoist. The ZX series electric hoist lifting motor is an imported NERI dual speed motor from Italy, which has strong horsepower and good cooling characteristics, low noise, low vibration, and a 60% power continuity rate. It can not only meet the requirements of frequent starting in a short period of time, but also increase the reliability of the hoist. The motor can be operated using dual speed or variable frequency control, ensuring smooth operation and fast positioning of the hoist, effectively improving productivity. The insulation level of the motor is F, and the protection level is IP55. The lifting motor is installed externally, which provides favorable cooling conditions and facilitates maintenance.

Gearbox - Cast aluminum gearbox body, with gears permanently immersed in oil, ensuring safety and reliability year after year. The hollow shaft of the gearbox directly drives the hoist drum shaft. Shock absorber coupling extends the lifespan of motors and gearboxes The gears have undergone surface hardening and precision grinding, with special tooth profile trimming and drum shaping to ensure smooth operation and high reliability. Spiral angle of 27 degrees, capable of transmitting greater torque, reducing gear module, and making the gearbox structure compact The gear accuracy is level 6, and all gearbox bearings use SKF bearings.

The ZX hoist is equipped with a safety safety lifting brake, using the internationally renowned brand Lenz brake The brake acts on the first reduction shaft of the gearbox, and this unique design allows the lifting brake to operate normally at any time, even in the event of a malfunction in the lifting motor or any component. The built-in electronic modular system is capable of automatic braking. Standardized installation of manual release device

The use of anti rolling wheels in small cars has made the era of using counterweights to extend the lifespan of wheels gone forever

Use reverse rollers to act under the beam without the need for counterweights.

The lifespan of the rolling surface of the wheel is extended.

The preloading mechanism effectively reduces the amount of wheel slip during light or no-load start-up.

Light weight and small size reduce shipping and transportation costs.

The maximum thickness of the applicable track flange is 35mm.

Torque type safety load cut-off device (overload limiter) prevents operators from accidentally overloading the hoist and crane structures

Protect operators and machines.

Accurately measure all loads of the lifting mechanism (rather than loads on one or two ropes).

• Can be easily adjusted according to the required lifting capacity.

• Do not reduce the effective lifting height. It does not rely on the measurement of current magnitude, but is directly activated by the load.

The heavy-duty rope guide ensures the correct rolling of the steel wire rope and prevents damage in the case of "loose steel wire rope"

Durable and practical design - a product of 60 years of production experience.

Selected molybdenum nylon material, highly resistant to breakage and permanent deformation. This material has self-lubricating ability and good elastic recovery performance.

When the operator lowers the hook pulley onto an object causing the rope to loosen, the built-in spring type rope pressing plate prevents the steel wire rope from blocking and damaging the rope guide.

The rope guide reduces the wear of the steel wire rope and drum.

• Easy to install.

The direct drive car is equipped with running wheels and horizontal wheels, which are durable and reduce wear and tear

The design of monorail driven trolleys is a major feature of Street's design philosophy.

It has been proven and widely accepted in the industry that small car wheels should be directly driven to ensure the long service life and reliability of the transmission system.

The operating drive is easy to disassemble, without the need to remove or intervene with the transmission device and operating wheels. The small wheels can also be easily removed.

The self correcting permanently lubricated bearings with lifelong sealing in the car bracket ensure that they can maintain a long lifespan even under maximum load.

The sturdy rimless and horizontal wheels not only eliminate the problem of flange wear but also extend the lifespan of the beam.

The practical design of using hinged doors makes all components easy to maintain.

Quick release heavy-duty plug and socket connection.

The timer accurately records the total working hours of the lifting motor.

The phase failure relay prevents the hoist from running out of control when one or more phases of the power supply are disconnected, and can also play the same role when the phase sequence is incorrect. The relay can also terminate the operation of the hoist in case of voltage loss or overvoltage, achieving protection

When the gearbox shaft runs at a speed 10% higher than the normal speed, the mechanical overspeed switch (optional) located in the gearbox will cut off the power supply to the hoist. This device uses mechanical control and does not rely on any software or microprocessor.

When the operating mechanism adopts a frequency converter, the cast aluminum heat sink exerts its powerful heat dissipation function to dissipate heat out of the electrical control box.

The wires are fitted with numbered tube clamps, making it easy to identify the wiring position.
