Non-Sparking Lifting Chain Hoist
Non-Sparking Lifting Chain Hoist is a hand-operated lifting appliance that is easy to use and easy to carry.Non-Sparking Lifting Chain Hoist can be used together with non-sparking manual monorail trolley to form a manual lifting and transportation trolley. In oil depots, gas production, chemical industry, military industry, electric power, mining, electronics, railways, and other potential fire hazards and explosion hazard environments, products rubbing against each other during operation will not produce mechanical sparks. Personal safety. It is also an indispensable special tool for machine manufacturing and machine maintenance.
Introduction
Non-Sparking Lifting Chain Hoist is a hand-operated lifting appliance that is easy to use and easy to carry. It has low pulling force, light weight, easy to carry, beautiful appearance, small size and long durability. The Non-Sparking Lifting Chain Hoist uses aluminum bronze and beryllium bronze as the blank. The shell of the chain hoist adopts H62 copper alloy material. Its rotating gear undergoes high temperature heat treatment to achieve high wear resistance of the gear.
Working principle
The working principle of the Non-Sparking Lifting Chain Hoist: by dragging the bracelet chain and the bracelet wheel, the friction plate ratchet and the brake seat (pressed together) rotate together. The five-tooth long shaft turns the plate gear, four-tooth short shaft and spline hole gear. Therefore, the hoisting sprocket installed on the spline hole gear drives the hoisting chain and smoothly lifts the weight.
Range of use
Non-Sparking Lifting Chain Hoists can be widely used in petroleum, petrochemical, oil stations, oil depots, gas production, chemical industry, military industry, power, mining, electronics, railways, and other potential fire and explosion hazard environments. No mechanical sparks are produced, which effectively prevents fire accidents and ensures national property and personal safety. It is also an indispensable special tool for machine manufacturing and machine maintenance.
Rules of use
1. Overloading is strictly prohibited. It is strictly prohibited to operate with power other than manpower. Before use, make sure that the mechanical parts are intact, the transmission part and the lifting chain are well lubricated, and the idling condition is normal. Check whether the upper and lower hooks are hung firmly before lifting. Wrong operation such as hanging heavy objects on the tip is strictly prohibited.
2. The lifting chain of the Non-Sparking Lifting Chain Hoist should be hung vertically without any twisted chain links, and the lower hook frame of the double-row chain must not be turned over. The operator should stand and pull the bracelet in the same plane as the bracelet, and rotate the bracelet in a clockwise direction to raise the weight; pull the bracelet in the opposite direction, and it will slowly descend at noon. When lifting heavy objects, it is strictly forbidden for people to do any work or walk under the heavy objects to avoid personal accidents.
3. During the lifting process of the Non-Sparking Lifting Chain Hoist, no matter the weight rises or falls, when pulling the bracelet, the force should be even and gentle. Do not use excessive force to avoid the bracelet jumping or snap ring. If the operator finds that the pulling force is greater than the normal pulling force, they should stop using it immediately. Maintenance method: after use, the gourd should be cleaned and coated with anti-rust grease, and stored in a dry place. Maintenance and overhaul should be carried out by those who are more familiar with the hoist mechanism, to prevent those who do not understand the performance principle of this machine from disassembling and disassembling at will.
4. After cleaning and maintenance, the Non-Sparking Lifting Chain Hoist should be tested with no load to confirm that it is working properly and the brake is reliable before it can be delivered for use. The friction surface of the brake must be kept clean. The brake part should be checked frequently to prevent the brake from malfunctioning and the self-falling phenomenon.
