Electric Chain Hoist - Henan Seven Industry Co., Ltd

Electric Chain Hoist Introduction

Overview

◈The electric chain hoist uses a disc brake motor as the power, and the planetary reducer reduces speed. It has the characteristics of compact structure, small size, light weight, high efficiency, convenient use, reliable braking, and simple maintenance. It is suitable for low-speed and small-stroke In terms of material handling, equipment installation, mines and engineering construction, it is inexpensive, high-quality, safe and reliable. It is widely used in petroleum, petrochemical, petrol stations, oil depots, gas production, chemical industry, electric power, mining, electronics, railways and other potentially fire and explosion hazardous environments.

◈Adopting international advanced technology, fine workmanship and tight gear matching, there are generally two types: hook suspension type and chain hoist electric trolley type. The chain hoists produced by our company have the characteristics of compact structure, small size, light weight, reliable performance, easy operation and wide range of use. SEVENCRANE electric chain hoist can be controlled on the ground using the handle, and can be controlled by wired (wireless) remote control.

5.Inverse phase sequence protecting device: It is the special electrical installation. which control the circuit not to work in case of wiring error in the power supply.

6.Controller: 24V low voltage Control handle with emergency stop button (Option: Wireless controller is also available with extra charge)

7.Limit switch: The limit switch device is installed where the weight is lifted on and off to make the motor to stop automatically so as to prohibit the chains from exceeding for safety.

8.Side magnetic braking device: This device shall realize the instant brake in case of the power dump.

9.Chain bag: Light, handsome and durable.

Product Features

Safety & Reliability

-Instant Power-Off Braking: Magnetic braking system activates immediately upon power loss for accident prevention.

-Leakage-Proof Design: 24V/36W transformer ensures safe operation in rain and high-humidity environments.

-Error-Proof Protection: Phase sequence protector blocks circuit activation during wiring errors.

Heavy-Duty Construction

-Lightweight Aluminum Shell: Enhanced cooling fins improve heat dissipation by 40%.

-Industrial-Grade Sealing: Fully enclosed structure for chemical plants, electroplating workshops, and harsh conditions.

-Double Steel Plate Frame: Ultra-sturdy support for maximum load stability.

Smart & Durable Components

-Auto-Limit Switch: Prevents chain over-lifting by stopping the motor automatically.

-High-Frequency Contactor: Built for repetitive heavy-duty operations.

-360° Rotating Hook: Hot-forged steel with anti-slip torque piece for flexible positioning.

Weather & Corrosion Resistance

-G80 Grade Manganese Steel Chain: After high-temperature forging treatment, the chain load-bearing effect is the best, smoother and does not jam the chain.

-Waterproof Controls: Durable, lightweight push button for reliable operation in wet environments.

Advantage

-The overall performance of the chain electric hoist motor is good, the safety and reliability of use are more guaranteed, and the probability of danger is reduced.

-The entire body structure of the chain electric hoist is very simple. It is convenient to install, disassemble, and repair, and has good maintainability.

-The clearance height is better, which effectively saves space, and multiple styles (fixed, low clearance, running) are not limited by small space.

-The shell is made of light aluminum alloy shell, which is light and strong, with high heat dissipation rate, and the fully sealed design is suitable for use in environments with poor working conditions.

-The three-in-one transmission technology provides excellent performance, and the lifting reducer made of high-quality alloy steel can achieve three-stage reduction, run very smoothly, have a long service life, and reliable performance, avoiding many shortcomings of long-distance transmission of the hoist intermediate shaft.

-More unique innovations, novel and beautiful appearance, exquisite and lightweight structure and humanized design (limit switch, double brake system, scientific switch, chain, chain bag, etc.).
