INTRODUCTIONS
DS-VG Lever Hoists are kind of portable and versatile hand-operated loading and pulling appliance with simple design making routine inspection or maintenance fast and easy.They utilize a ratchet and pawl mechanical configuration to incrementally raise or lower a load or to apply or release tension. DS-VG Lever hoists are exceptionally convenient for working in narrow or restricted places, outdoor aloft work and pulling from different angles or at high levels, which have an inherent ability to be used in vertical and horizontal applications.
DS-VG lever hoists utilize reasonable pulling force to rated capacity, which is more efficient to operate the equipment. They have compact structure, and light weight which makes them easy to carry and for store. All the lever hoists adopt high quality alloy steel with high strength and the best quality such as corrosion-resistant, moisture-resistant, so they have long lifespan. The realization of lightweight can be a reality thank to the no change of size, which is a great superiority. They have no problem in operating at high level or narrow spaces. They show the great excellence characteristics in pulling and lifting goods in tough situations. Even in tight quarters or in elevated work locations, they are convenient stored in a special carrying case. Those great qualities owes to the strict test for safety and efficiency during producing process, so they show great advantage in harsh environments.
DS-VG type lever hoists are designed with a single-step reduction gear which is characterized by a small manual fastening force and assured load holding. The reliable loading fastening can be provided to the last clicking of the lever. And the steel was thickened so that the strength has greatly improved. The innovative technology of DS-VG lever hoists makes them extremely great. Owing to the G100/G80 chains, the safety factor is high and they have high durability. The unique design make products more elegant and the hand wheel can adjust the length of chains to the required position, which greatly improve the efficiency of lifting. DS-VG lever hoists have stable operation and can bear heavy loads. The comfortable grip provide operators great handling.
DS-VG lever hoists adopt Japanese technology but with much lower price, lots of parts are interchangeable with lever hoists. They are structurally designed for increased rigidity which strengthens the body to withstand extreme loads efficiently. What’s more, the hardened side plates help prolong chain wear by cutting down abrasion. Besides, special specifications and marks can be made according to customers’ requirement. However, you should pay attention that it is use labor power to lift heavy, so you cannot increase the length of operating handle optionally.
The function of the lever hoists is for installing equipment, pulling materials in ship building, electric power plants, transportation, factories, shipping, sea works, air works, vessel manufacturing, industrial construction, mine or other fields. Also they show great excellence operation in bridge building, warehouses, shipyard, forestry, civil engineering, where however bad the conditions is, DS-VG lever hoists can always handle well.
They are also called DS-VG type manual lever hoists, DS-VG chain lever blocks, ratchet lever hoists, chain lever hoists, blocks with G100 chain.
DETAILED DESCRIPTION
1.Chain
The lifting chain adopts the level 100 nickel plated chain, default chain is G80, level 100 nickel plated chain is also available for strict usage. Furthermore, chain test can achieve 4 times breaking, which has high safety factor and long service life. Compared with G80 chains, they are 25% stronger than them.
Cause they are made from a special high strength alloy, the feature unbeatable combination of toughness and resistance and wear.
2. Spray
Special processing makes it smooth and shining permanent coating can achieve the purpose of decoration and corrosion-resistant.
3. Flexible clutch technology
The adoption of unique clutch technology make DS-VG lever hoists can lift goods at any high grade.
4. Handle
The reinforced handle has high strength, light weight with non-slip set, which is safer and more reliable. It also has superior rubber grip with fastening screws.
5. Hooks
The new design of forging type hooks of which the top is safe and has slowly bending performance. Besides, the widen tooth make it can bear heavy loads. Both upper and lower hooks are shaped by forging and they have fine appearance and high intensity.
6. Cast latch
The hook is equipped with safety mechanism, hook latch to help strengthen and protect vulnerability points. The thicker material makes latch stronger and engagement with the tip of the hook creates secure closure.
7. Hand wheel
The unique hand wheel with knob design is different conventional free wheel system.
8. Screws
The whole products adopt non-slip fastening screws.
9. Gears
DS-VG lever hoists utilize the best tooth-shaped rounding and high impact gears.
10. Brake
Thanks to the double pawl brake system, the safety factor is increased twice. The patented fused brake is unbreakable, anti-oil, anti-skid with good braking performance. DS-VG lever hoists deliver positive performance thanks to a brake design incorporating two moisture-resistant asbestos-free brake pads and four braking surfaces, which includes two brake pawls for added reliability.
11. Bearings
The caged roller bearings are equipped on load sprocket and thrust bearings are installed in bottom hook assembly. High-quality needle bearings which increase performance have long service life and ease of maintenance.
12. Chain guide
The chain guide system is simple, allowing operation in horizontal position, which can make sure smooth and avoid jammed when you are pulling the load chain.
13. Stop knob
The stop knob is designed to protect the lever hoist even the operators wrongly put the loading on the end ring. Operators should use the knob to quickly and easily adjust the chain. The unique design safeguards against inadvertent freewheeling under load.
14. Fused brake disc and ratchet disc
The Ratchet disc and Friction Plate/Discs are fused together. This design greatly increases the brake service life and reduces wear and tear while offering greater oil repellent.
15. Movable end link
16. Enlarged end ring
17. Bag-nuts
The bag-nuts improve the maintenance performance. Nuts fasten the gear case and brake cover protecting the screw from damage and make maintenance easier.
18.Anti-release system
The unique system makes the chain-length can be quickly adjusted to the desired position, which greatly improve the efficiency.
19. Frame
They adopt high grade alloy steel with solid construction, a patented induction hardening process on the load-supporting part, and increased material thickness produces an extremely strong and rigid frame.
20. Protecting guard
The lever block feature a guard protecting the chain pin and nuts from damage, enhancing safety.
21. Load signal
The load signal works to alert the operators when lever hoist is used to lift loads beyond rated capacity, Alert is indicated by green signal changing to red.
Others
1. Technical parameters include capacity, type, standard lifting, load chain falls, rated load, running test load, net weight, gross weight and others.
2. Packaging & Shipping
one pc in 5ply carton or wooden box with pallet outside to protect goods well
The most suitable way will be chosen to deliver your goods.
one year guarantee for whole products
Each product is tested at 1.5times of the rated capacity.
Complied with EN 13157
Cautions
1. It is strictly prohibited to overload, lengthen the handle without permission, and strictly forbid other power operations other than human resources.
2. When lifting heavy objects, it is strictly prohibited to do any work or walk under the heavy objects to prevent personal accidents.
3. Before use, make sure the machine parts are in good condition, the transmission parts and the lifting chain are well lubricated, and the idling condition is normal.
4. Check whether the upper and lower hooks are fastened before use. Load should be added to the center of the hook chamber of the hook.
5. If you find that the hand lever force is greater than the normal one, stop using and immediately check the lever hoists.
