Explosion-proof hand hoist is a kind of manual lifting machine which is easy to use and carry easily. It has small tension, light weight, easy to carry, beautiful appearance, small size and durable. Explosion-proof hand hoist is a kind of manual lifting machine which is easy to use and carry easily. It has small tension, light weight, easy to carry, beautiful appearance, small size and durable.
Explosion-proof hand calabash is made of aluminum bronze and beryllium bronze as blank, and the shell of hand calabash is made of H62 copper alloy. The rotating gear is heat-treated at high temperature to achieve high wear resistance. Explosion-proof hand calabash is made of copper alloy. Heat generated in a short time is absorbed and conducted; Because copper itself is relatively soft, friction and impact has a good retreat, not easy to produce small metal particles. The production approval of explosion-proof hand hoist shall conform to the national explosion-proof tool GB10686-1989 standard, and the mechanical performance shall reach the relevant national standard.

Explosionresistant hand hoist can be widely used in petroleum, petrochemical, oil station, oil depot, gas production, chemical industry, military industry, electric power, mining, electronics, railway, and other potential fire and explosion dangerous environment, in the operation of product friction collision will not produce mechanical sparks, effectively prevent fire accidents, to ensure the safety of national property and personal. It is also an indispensable special tool for mechanical manufacturing and mechanical maintenance.
Overload is strictly prohibited. It is strictly prohibited to operate with power other than manpower. Before use, it must be confirmed that the machine parts are intact, the transmission part and the lifting chain are well lubricated, and the idling situation is normal. Check whether the upper and lower hooks are securely hung before lifting. It is strictly prohibited to do wrong operations such as hanging heavy objects on the tip.
Explosion-proof hand hoist lifting chain should be suspended vertically, there should be no wrong twisted chain ring, the lower hook frame of the double row chain should not be overturned. The operator should stand in the same plane as the sprocket and pull the chain, so that the sprocket rotates clockwise, so that the weight can rise; Reverse pull hand chain, noon can slow down. When lifting heavy objects, it is strictly forbidden for personnel to do any work or walk under heavy objects to avoid personal accidents.
Explosion-proof hand hoist in the process of lifting, no matter the weight rises or falls, when pulling the hand chain, the force should be uniform and gentle, do not force too hard, so as to avoid the hand chain jumping or clashing. If the operator finds that the hand tension is greater than the normal tension, it should stop using immediately. Maintenance method: After use, the calabash 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 familiar with the hoist mechanism to prevent those who do not understand the performance principle of the machine from disassembling at will.
After cleaning and maintenance, the explosion-proof hand hoist should be carried out no-load test to confirm that the work is normal and the braking is reliable before it can be delivered to use. The friction surface of the brake must be kept clean. The brake part should be checked frequently to prevent brake failure and the phenomenon of falling from the object.
