Fixed crane

Fixed Crane 完整中英对照翻译（纯英文 + 精准中文） Fixed Crane 固定式起重机 1. 定义与核心特点 A fixed crane is a type of boom crane permanently or long-term anchored to concrete or steel foundations. It has no traveling mechanism and operates only in a fixed position with slewing and luffing functions. It features high stability, heavy load capacity, high efficiency and low maintenance, yet it cannot move freely and requires complex disassembly for relocation. 中文：固定式起重机是臂架类起重设备，永久或长期固定在混凝土 / 钢结构基础上，无行走机构，仅可原地回转、变幅作业。具备稳定性强、载重量大、作业高效、维护简单的优势；缺点为无法自主移动，转场需拆解重装。 2. Main Structure Foundation: Heavy concrete or steel base to bear overall weight and loads. Slewing platform: Equipped with slewing bearings for 360° rotation. Boom system: Truss structure, adjusted by luffing cylinders or steel wires. Operating mechanisms: Lifting mechanism, luffing mechanism and slewing mechanism. 中文： 基座：重型混凝土 / 钢制底座，承载整机自重与荷载 回转平台：配置回转支承，可 360° 旋转 臂架系统：桁架式结构，由变幅油缸或钢丝绳调节角度 工作机构：起升机构、变幅机构、回转机构 3. Common Types Port fixed crane Fixed tower crane Jib crane (wall-mounted / pillar fixed) Marine deck fixed crane 中文： 港口固定式起重机 固定塔式起重机 悬臂起重机（墙装 / 立柱固定式） 船用甲板固定式起重机 4. Application Scenarios Port terminals, industrial factories, warehouses, high-rise construction, marine and offshore engineering for frequent heavy cargo lifting and handling. 中文： 广泛应用于港口码头、工矿厂房、仓库、高层建筑、船舶及海洋工程，适用于高频次重型货物吊装与装卸作业。 5. Advantages & Disadvantages ✅ Advantages Strong wind resistance & anti-overturning performance, large lifting capacity, precise operation, long service life, low daily maintenance cost. ❌ Disadvantages Fixed working range, immovable on-site, high foundation cost, complicated installation and removal. 中文： ✅ 优点：抗风抗倾覆能力强、起重吨位大、操作精准、使用寿命长、日常维护成本低 ❌ 缺点：作业范围固定、现场不可移动、基础建设成本高、安装拆卸工序复杂 6. Core Parameter Rated lifting load, maximum working radius, full-circle slewing, heavy-duty working class. 中文：额定起重量、最大工作幅度、全回转作业、重级工作级别
