In order to meet the diverse needs of users, we have designed a variety of electrical control systems for DC electric chain hoists, and equipped DC electric chain hoists with many standard components to adapt to the needs of users' sites and processes.

מנוף הזרוע הנייד בעל טווח מתלים גדול יותר והוא חסכוני ועמיד. הוא מצויד בסוכנות נסיעות מובנית, שהיא בטוחה יותר וקטן יותר בגודלה, מה שמועיל במיוחד להגדלת מהלך הקרס. עבור עגורן זרוע זז של SEVENCRANE עם ציוד הרמה, כל לוחות הפלדה המתקבלים מונחים על בסיס הזרוע. תוכנות מחשב שנמצאות כיום בשימוש נוטות לשים לב רק לפיזור האחיד של מוטות פלדה מעוקלים לאורך רצפת קורות התיבה. אם כי מוטות הפלדה האורכיים מספיקים. עם זאת, על פי המאפיינים של ניתוח המתח של המצב בפועל, עקב ריכוז הלחץ בשורש קצה שלוחה, רשת הסיבים בשורשים בשני הקצוות פוחתת בהדרגה.

The portable jib crane on wheels is a lifting machine that is used with an electric hoist or a hand chain hoist. It is a small lifting equipment that is easy to move and popular. SEVENCRANE portable jib crane on wheels has a larger suspension span and is economical and durable. It is equipped with a built-in travel agency, which is safer and smaller in size, which is especially beneficial to increasing the stroke of the hook. In a freestanding portable jib crane on wheels, all steel plates obtained are placed on the base of the jib. Computer programs currently in use tend to only pay attention to the uniform distribution of longitudinally curved steel bars across the floor of the box girders. Although the longitudinal steel bars are sufficient. However, according to the characteristics of the stress analysis of the actual situation, due to the stress concentration at the root of the cantilever end, the fiber mesh at the roots at both ends gradually decreases.

The working intensity of the SEVENCRANE mobile jib crane with lifting equipment is light. The main structure of this type of jib crane is composed of a column, a slewing arm rotation drive device and an electric hoist. The lower end of the column is installed on a movable pedestal foundation, and a cycloidal pinwheel reduction device drives the cantilever rotation. The electric hoist moves left and right in a straight line on the cantilevered I-beam and lifts heavy objects. The crane's cantilever is a hollow steel structure with light weight, large span, large lifting capacity, economy and durability.

Automated cranes in inland yards of large container ports are mainly divided into tire-type container cranes and rail-type container cranes. This type of gantry crane produced by SEVENCRANE yard gantry crane manufacturer is a special machine used for loading, unloading, transporting and stacking containers at container terminals and container transfer stations. RMG is driven by electricity. Because of its energy saving, environmental protection, low cost and low failure rate, it is the preferred yard operation machine for new terminals now and in the future. Orbital gantry cranes are generally larger than tire-type gantry cranes and have more stacking layers. Because the orbital gantry crane travels along the track laid on the site, it can only operate within a certain site range of the track. The orbital gantry crane has strong positioning capabilities and is easier to realize fully automated loading and unloading. It is an ideal machine for automated container terminals. We are one of the CE approved yard gantry crane supplier in China, we have run in crane industry for more than 30 years. If you want to purchase the yard gantry crane, then we can be your reliable chinese supplier yard gantry crane factory.

The working intensity of the cantilever crane is light. The crane is composed of a column, a slewing arm rotation drive device and an electric hoist. The lower end of the column is fixed on the concrete foundation through anchor bolts. The cycloidal pinwheel reduction device drives the cantilever rotation.
