Explosion manual hoists Introduction


Explosion manual hoists: aluminum bronze, beryllium copper as a rough, manual hoists H62 copper alloy shell with proof chain hoists applicable in explosive environments,electric wire rope hoist such as chemical, offshore and other operations.
Explosion manual hoists turning gear after high-temperature heat treatment to achieve a high gear, according wear. Explosion-proof chain hoists bracelet pull small, light weight, easy to carry, beautiful appearance, small size, durability.
Explosion manual hoists work principle: Hands chain drag chains, bracelets wheel began to turn, friction ratchet,mechanical lifting devices brake seat (to be pressed into one) common rotation, five major axis will rotate sprocket teeth, four teeth and minor axis spline Kong gears. Thus, the device lifting sprocket holes on the spline drive gear on lifting chain, lifting heavy objects smoothly.

Hoist equipment structural featureshand chain hoist


Hoist equipment including motor, hoist, chassis, shields and other components; using three deceleration mode,hand chain hoist with spiral pay transmission output torque greater. Hoist steel supporting civil overcome irregularities in order to reduce overall noise and vibration.
Hoist equipment using outdoor long duty motor, protection class ≥IP155. Stroke control mechanism using the principle of the decade counter, the stroke control error 0.5%.Hoist equipmentorque control is the axial displacement protection through the worm touch micro switch,Hoist equipment
  to achieve protection of electrical principles.hoist equipment easy operation and maintenance, enabling on-site and remote control operation.

Explosion Manual Hoist Introduction


1. Liftech Equipment Explosion Manual Hoist: aluminum bronze, beryllium copper as a rough,lifting clamp chain hoists H62 copper alloy shell with proof chain hoists used in explosive environments, such as chemical, offshore and other operations.
2.-proof chain hoists turning gear after high temperature heat treatment to achieve a high gear, according wear. Explosion-proof chain hoists bracelet pull small, light weight, easy to carry, beautiful appearance, small size, durability.
3.Liftech Equipment proof chain hoists work principle: through hands-chain drag chains, bracelets wheels began to turn, friction ratchet, brake seat (to be pressed into one) co-rotating,lifting equipments five major axis will rotate sprocket teeth, four teeth short axis the gear and the spline hole. Thus, the device lifting sprocket holes on the spline drive gear on lifting chain, lifting heavy objects smoothly.

Three phase electric hoist Cautions


Three phase electric hoist in the use of safety and technical conditions before checking hook, wire rope,5 ton electric chain hoist reducer and other consumable parts. When in use, prohibit persons from entering the danger zone and sent people hoisting care. three phase electric hoist placed when lifting or bundled items must be standardized in line with lifting requirements, the brakes, the safety device failure, the next hook nut locking device is damaged, rope and other damage to be scrapped prohibited lifting operation. Hanging objects tied, hanging strong or imbalance may slip,small electric hoist not for lifting operations are not padded edges between objects and wire rope hoists. Unable to see the sites, not for lifting operations suspended matter the situation and command signals. In stoppage or rest, get the hanging objects, hanging baskets, spreader and cable hanging in the air.

three phase electric hoist maintenance


1 after a new installation or dismantling installed three phase electric hoist, should first be empty commissioning several times. Former but not installed, avoid power test switch.
Should be carried out prior to normal use of the rated load of 2 to 125%, up from approximately 100 mm above the ground,portable electric hoist the static load test of 10 minutes, check whether it is normal.
3 Dynamic load test based on the weight of the rated load, as repeatedly lift and move around the test, checking the mechanical transmission parts After the test, the electrical part and the connecting portion is normal and reliable.
4 using three phase electric hoist, the absolute prohibition under circumstances not permitted, and exceed the rated load and nominal closing per hour (120 times) the case.
5. installation and maintenance, must strictly limit device is flexible and reliable inspection, when the limit was raised to the position of the hook, hook it to the shell casing from the rolls must be greater than 50mm (10t, 16t, 20t must be greater than 120mm). When the hook dropped lower limit position, should ensure the safety rope on the drum circle, circle must be safe and effective in more than two laps.
6. allowed to press the two make three phase electric hoist in the opposite direction of movement of the flashlight door button.
7 After the completion of the work must always pull the brake power, cut off the power.

Liftech Equipment Manual Hoist usage rules

Liftech Equipment Manual Hoist stayed overload use is strictly prohibited. Do not operate with a power other than human.magnetic lifter Before using the parts required to confirm intact, transmission parts and lifting chain oiled, idling normal. Liftech Equipment Manual Hoist lifting hook before checking whether hanging down firmly, lifting chain should be hung vertically, not a wrong twist of chain link, double under hook rack chain not flip.
Liftech Equipment Manual Hoist operator should stand on the same plane with the bracelet round hands pulled the chain to make bracelets wheel rotates clockwise, you can make the weight rise; reverse hands pulled the chain, the weight can slowly decline. When lifting weights,monorail wire rope hoist is prohibited personnel action to do any work or walk under a heavy object, in order to avoid a major accident. In the lifting process, regardless of the weight up or down, drag chain hands, the force should be uniform gentle, do not use too much force, so as not to hand chain jumping or snap ring. When the operator is found hand-pull tension greater than normal, you should immediately stop using it. Prevent damage to the internal structure,mechanical lifting devices to prevent falling objects accident. After heavy to be safe and secure landing, then remove chain hoists under the hook. Use Liftech Equipment Manual Hoist finished, gently, in a dry, well-ventilated place, apply lubricant put away.

Liftech Equipment Manual Hoist works


Liftech Equipment Manual Hoist as an upgraded version of the fixed pulley, fully inherits the advantages of fixed pulley,Manual hoist while using a combination of reverse backstop brake reducer and chain pulley block, the symmetrical arrangement of two spur gears rotating structure, simple, durable and efficient.
Liftech Equipment Manual Hoist hands by pulling the chain, bracelet wheel rotation, the friction plate ratchet,trolley manufacturers brake pressure into one common rotating seat, then the long axis of rotation of sprocket teeth, tooth spline hole short axis and gear. This means lifting sprocket holes on the spline drive gear on lifting chain, thereby lifting heavy objects smoothly. Using one-way ratchet brake friction plate, on their own under load brake pawl engagement with the ratchet under the action of the spring, brake safety.
