Lifting equipment Are divided to eight categories:
Each of these types are designed and manufactured for specific applications, which are briefly described below.
Hook block:
The new ZARRIN MEHR hook blocks are designed according to the latest requirements and techniques of the FEM1001 and DIN15020 standards. Safety in the event of failure in all cases is greater than that recommended by FEM standards. The pendant parts (hooks, cross-axels, nuts) are in accordance with DIN15411 and hooks are designed in accordance with DIN15401,15402 and are made of forged grade steel (StE355 (class P, DIN 15400). Of course, the class S, T and V They are also custom-made. To prevent chain escape, all hooks are equipped with safety guards.
The pulleys are designed and constructed in accordance with the relevant standards by ZARRIN MEHR Engineering Co., and are connected to the main shaft by double roller cylindrical ball bearings, due to the lubrication a lubricating nipple created at the bottom of the main shaft . At the time of the construction of the sheaves, special attention is paid to the throat of the groove.
The definition of the radius of the groove in accordance with the standard (DIN 15601 (r = 0.525 d)) increases the lifetime of the wire rope considerably, and if the wire rope is properly fitted to the pulley’s throat, its lifetime will increase to the maximum state . The rollers that are hardened by thermal stress will increase the lifespan of the steel rope and will be made by customers order. The distance between the pulleys and other components of the hook block is very low due to the selection of the bearings, which leads to a reduction in the size of the hook block.

Lifting beam :
Spreader beam and lifting beam are Two different types of under hook loading devices that are used to fix and support load during lifting. Both types of devices are used to hold wire ropes under the machine at a 90 degree angle or close to 90 degrees (perpendicular to the horizon). In this way, the beam prevents damage to the load, damage to the crane hardware and wire ropes, and prevents slipping of wire rope that are attached to the load during lifting. While the spreader beam and lifting beam are the most popular types of under the hook load attachment devices , there is a great deal of difference about both, both in design and how they are used. The main difference between the two types of beams is the forces that are applied to the main girder.

Coil Lifting Equipment:
If you’re dealing with a coil and are looking for a solution for handling them, the ZARRIN MEHR C-Hook is a great option. ZARRIN MEHR coil hook is a safe, efficient and fast solution for moving coils. The use of the best product for material handling is very important, therefore, the ZARRIN MEHR coil hooks have a spine of a single piece of alloy steel and are designed and manufactured to work in a high working group and tough conditions.

Roll lifting equipment :
One of the most efficient roll handling equipment is the roll lifting beam that is designed to move and handle roll by using the roll shaft. For those cases with a height limit, the ZARRIN MEHR roll lifting beam is the best choice for handling roll with overhead cranes or forklifts. All ZARRIN MEHR roll handling equipment are designed according to the latesst standards, such as ASME B30.20 & BTH-1.
