Load capacity 500Kg~2 tons, 1Hp variable frequency (speed control) dual speed

The lifting mechanism adopts a variable frequency speed control design to meet the needs of fast handling and slow positioning.

Features

• The braking resistor is mounted on an aluminum alloy casing and equipped with a hollow metal protective cover, which takes into account both heat dissipation and safety.
• Traditional overhead cranes are mostly single-speed designs. The intense vibrations during hoisting and braking can cause the transported goods to sway or become unstable, leading to injuries to personnel and making the goods prone to damage when they reach the ground.
• The lifting mechanism is implemented using the variable frequency principle.Speed ​​control design (optional)This eliminates the violent speed jumps that occur when switching between fast and slow speeds in polarity motors or dual-motor designs.
• Traditional cranes use full-pressure starting and brakes are activated while the motor is still at high speed, causing motor overheating and excessive brake wear.
• By controlling the brakes and motor through the principle of frequency conversion, when the stop command is issued, the controller generates a reverse braking torque to the motor. The brake is activated when the motor speed approaches zero, which can effectively extend the life of the brakes and motor.

Advantage

• Stepless speed control reduces the swaying and shaking of loads during handling.
• When raising/lowering or positioning loads, it can significantly reduce the impact and vibration on structures and equipment.
• It saves electricity and extends the lifespan of mechanical parts.
• Built-in multiple protection functions: voltage detection, current detection, phase loss detection, and temperature detection.

Standard Functions

• Motor protection functions: overvoltage, overcurrent, and motor overheat protection.。
• Mechanical overload protection device for chain and hook breaking load > 5 times rated load.。

Purchase Functions

• Light load high speed function
• Upper and lower limit switches

 Option

• Industrial-grade wireless remote control
  Single-stage button + variable speed knob or double-stage button (stepless adjustment for slow speed)
• Wired push-button switch with emergency stop switch / rotary speed control type
• Speed ​​display

Control method: Suspension-type push-button switch

Power requirements: 3-phase 220/380/415/440/460V 50/60Hz

Remark :

• Maximum speed = The default value is 60Hz, the motor's rated frequency. A light-load overclocking function is available as an option to achieve a faster handling speed.
• Slowest speed = factory default 6Hz, manufactured after 100% load test at 1Hz. [Other speed settings to be discussed].
• Control switches: Dual-speed button is standard; single-speed button + variable speed knob or dual-speed button (slow speed can be adjusted steplessly) are optional.
• Power supply model: 3-phase 220~460 needs to be specified in advance.
• Load capacity ≤ 0.5 tons [A more economical two-speed CSC is also available.]。
