Features

■ Hoisting Motor
Optimized motor design for low-vibration and quiet operation.  Uses squirrel cage motors with cylindrical rotor for hoisting duty. Type of protection IP 54 (IP55 is optional), loading time: 40%, Optional 60% duty cycle motor and mandatory cool fan to comply with high frequency uses.

■ Gearbox
The gear unit is a 3-stage helical gearbox with high endurance gearing that the material consists of processed alloy steel (SCM415) and the heat treated hardness reaches HRC60 degrees, for solidity, durability, and high precision.

■ Fast Acting Brake
The disk electromagnetic brake features automatic braking in the event of a power failure.  Asbestos-free lining can reach 1,000,000 times under a normal application.  A 2nd mechanical brake is optional.  Long serving and trouble-free mechanical brake provides a dual braking system to ensure operational safety.

■ Limit Switch
Automatically cuts off the hoisting and traveling motions in upper, lower, left and right limit positions.  Preventing mechanical failure from over traveling of the hook.

■ Hook Block
The 360° swiveling hook is made of high strength and high resistance forged steel and is fitted with a swiveling crossbar.  The elegant bottom blocks are equipped with protective edging around the rope opening and are provided with an anti-drop safety latch.

■ Wire Rope
The wire rope is made of high fatigue-strength and wear-proof flexible steel.  A design safety factor of 4.5 is in accordance with ISO, JIS, CNS, and CMAA #70 standards.

■ Protective Rope Guide
Made of tough plastic, the rope guide lead-in by means of hardened pressure rollers mounted on anti-friction bearing. The rope guide also reduces wear on the rope and rope drum to enhance the safety and durability.

■ Push Button Switch (IP65) with EMS
The main line On/Off switch lets you cut off power by pressing a button close at hand rather than at the primary power source.  The advanced features of water-proofing and dust-prevention meet IP65 improving its flexibility and durability.  The emergency stop as our standard specification is the added-on safety device for our valued customers.

■ Panel for electrical connections
Magnet contactor is operated through a push button switch or remote controller, and electric parts and cable are clearly labeled for easy repair and maintenance.  Control boxes have good water-proofing, dust-proofing, and the enclosure meets IP54 specifications.  Standard main voltages are 3 phase 380-440V 50/60Hz and standard control voltage is 48V.  Other main and control voltages are also available by request.

■ Overload Protection
Mechanical overload protection cuts off the power to the motor to prevent object lifting in case of excessive over loading.

■ Frequency Inverter Control
A frequency inverter provides variable hoisting speeds for smooth lifting and stopping, as well as variable cross travel for low-sway travel motions. Fast and exact positioning enhances the performance in overhead material handling.  Reducing power consumption to save energy is an additional benefit of the frequency inverter application.
