Dongqi 1t HD Overhead Crane 6m Lift Workshop Low Price Djibouti

Product Overview

The HD model European-spec single girder overhead crane from Dongqi Crane is engineered to FEM and DIN standards with a design philosophy centered on small dimension and light dead weight. It is intended for facilities where headroom is limited, hook approach to walls matters, and building structure should not be over-designed for crane loads.

Compared with traditional single girder overhead cranes, the HD model delivers a minimum limiting distance from hook to wall, lower headroom, and higher lifting height under the same building height, effectively releasing vertical and lateral workspace that conventional cranes consume. The crane is predominantly used indoors, and can also be configured for outdoor service where conditions require.

Dongqi Crane supplies the HD model as a modular lifting system: the crane frame, trolley, hoist, and electrical controls are built as separable, interoperable modules, allowing the configuration to be matched to capacity, span, lifting height, duty cycle, and working environment rather than forcing a single fixed design.

Design Philosophy: FEM/DIN and Lightweight Engineering

The HD model is not a conventional crane with a lower-profile hoist bolted on. The structural and mechanical systems are designed from the outset to FEM/DIN criteria:

• Computer-optimized box-type main girder — web plates are CNC-cut and formed to accurate deflection profiles, balancing rigidity against dead weight.

• Modular construction — motor, reducer, brake, and electricals are arranged as separate serviceable modules, reducing maintenance downtime compared with integrated designs.

• Low-clearance trolley and compact hook block — the hoist runs close to the girder, preserving hook travel without increasing building height.

• Three-in-one drive with stepless speed control — motor, brake, and hardened reducer integrated into a compact unit, with smooth acceleration and reduced mechanical shock.

• Shot blasting to Sa2.5 after welding and stress relief, followed by epoxy zinc-rich primer at 140 μm dry film thickness for corrosion protection.

The measurable result of this approach is a crane that is 20–30% lighter in overall dead weight and requires 20–25% less headroom than conventional single girder cranes of comparable capacity and span. On the runway side, the lighter dead weight translates into 15–20% lower maximum wheel pressure, reducing the structural demand on runway beams and building columns.

Technical Specifications

Working class note. FEM M5 / ISO A5 corresponds to medium-duty service, typically around 12,500 total operating hours, and is the standard classification for general machine shops, fabrication shops, and moderate-use production environments. Dongqi can review higher-duty requirements (M6 / A6, M7 / A7) during configuration if the application involves continuous production or heavy cycling.

Advantages Over Traditional Single Girder Cranes

The HD model’s FEM/DIN-based lightweight design produces advantages that are measurable at the building level, not only at the crane level.

Lower headroom, higher lifting height

The compact trolley and low-clearance hoist arrangement recover vertical space that conventional cranes lose between the girder and the hook. In practical terms, a European-spec crane can recover approximately 400–700 mm of vertical working space compared with a conventional low-headroom arrangement, depending on capacity and configuration. Under the same building height, the HD model therefore yields a higher usable hook lift.

Closer hook approach to the wall

The minimized hook-to-wall distance means the crane can serve a wider effective bay width. Loads can be positioned closer to side walls and end walls, expanding the functional working area without increasing the building footprint.

Lower dead weight and reduced wheel load

The lighter girder and compact hoist reduce maximum wheel pressure by 15–20% relative to conventional single girder cranes. This has a direct cost consequence: runway beams and building columns can be sized for lower loads, often reducing structural steel and foundation investment in new construction, and making crane addition more feasible in existing buildings with limited reserve capacity.

Smoother operation and precise positioning

Inverter control on hoisting, trolley travel, and crane travel provides stepless speed regulation, soft start/stop, and reduced load swing. This supports assembly and positioning work where conventional single-speed cranes are difficult to control precisely.

Lower noise and simpler maintenance

The three-in-one drive and precision-machined travel components reduce operating noise, while the modular layout allows individual components to be serviced or replaced without dismantling the full drive train.

Hoist Options for the HD Model Overhead Crane

The HD crane frame accepts multiple Dongqi hoist types, so the same crane platform can be matched to different headroom, capacity, environment, and track requirements.

NR Type Low Headroom Electric Hoist

The NR type is the default low-headroom choice for the HD crane. Its modular design and low-clearance structure maximize working height and expand the usable area under the crane. It is suited to standard indoor workshops where vertical space is the primary constraint.

BNR Type Explosion-Proof Electric Hoist

The BNR type is designed for flammable and explosive environments, with explosion-proof performance matched to hazardous-area requirements. It serves as the main lifting mechanism for explosion-proof bridge cranes and preserves the low-headroom, high-lift geometry of the HD platform. Available across the capacity range with work levels appropriate to hazardous-area service.

NRS Type Standard Headroom Electric Hoist

The NRS type uses a modular design with an independent running trolley. It is recommended for capacities of 16 t and above, or where the track is curved. The independent trolley configuration provides a more robust travel arrangement for heavier loads and non-straight runways.

WBH Type Electric Chain Hoist

The WBH type is a newly designed European-spec electric chain hoist. It combines high performance and safety reliability with a humanized design concept, aimed at increasing productivity in applications where a chain hoist is preferred over wire rope for speed, duty, or handling characteristics.

Safety and Electrical Protection

The HD model is supplied with safety devices matched to the working duty and operating environment. Standard and available protection includes:

• Overload limiter / load limiting device to prevent lifting beyond rated capacity.

• Upper and lower limit switches for hoisting travel, and travel limit switches for trolley and crane motion.

• Emergency stop circuit and phase-failure / phase-sequence protection; main power disconnects automatically on phase stagger.

• Safety disc brake on the hoist, with holding capacity designed for secure load retention.

• Anti-derailment devices and buffers (honeycomb-type) at travel extremities.

• Infrared anti-collision protection between cranes or end approaches (configuration-dependent).

• Audible and visual alarm indicators for travel and lifting motions.

• Etch-proof control handle with IP54 protection, heavy-duty aviation connector, and electrical components positioned for safe, accessible maintenance.

• Optional recording black box for operating data capture, available on request.

Electrical components are sourced from qualified suppliers, with phase protection, voltage protection, and thermal overload protection integrated into the control system.

Control Options

The HD model supports flexible control configurations to match operator positioning and workflow:

• Pendant control — suspended from the crane girder for ground-level operation, with display for monitoring.

• Radio remote control — with display and proportional push buttons; optional power and signal transmission via energy chain system.

• Cabin control — available for large-span or high-duty applications where an operator station is preferred.

• Inverter / VFD control on hoisting, trolley travel, and long travel for stepless speed and soft start/stop.

Applications

The HD European-spec single girder overhead crane is engineered primarily for indoor material handling, with outdoor configurations available when required. Typical application environments include:

• Workshops and maintenance shops — general lifting, assembly, and repair work.

• Warehouses and logistics centers — pallet, drum, and packaged goods handling in high-bay or headroom-limited storage.

• Shipyards and marinas — lifting and positioning in constrained hull or dock-side spaces.

• Steel mills and heavy fabrication — where moderate-duty lifting is required and building structure should not be over-loaded.

• Military facilities and specialized industrial sites — where compact dimensions and low hook approach are operationally important.

• General manufacturing, machinery, metallurgy, petroleum, petrochemical, ports, railway, civil aviation, electricity, food processing, paper, building materials, and electronics — Dongqi’s European single girder range is applied across these workstations and workshops.

The HD model is particularly suitable for existing buildings with limited headroom or structural reserve, and for new projects where reducing building height or runway steel weight is a project-level cost objective.

Selection Guidance

The following practical thresholds help determine whether the HD model and which hoist option fit an application:

For applications near the upper capacity, span, or duty limit, Dongqi reviews wheel load, building clearance, and hoist group together rather than quoting a crane in isolation.
