10T gantry crane installation plan

I. Project Overview

This project involves the installation of a 10T gantry crane, undertaken by China XX Group Co., Ltd. The equipment will be dismantled from its original site and reinstalled at a designated factory. The crane’s main beam is a frame structure, weighing approximately 40T, with a span of 20 meters and a lifting height of 10 meters. This constitutes a large-scale equipment installation project. To ensure construction safety and efficiency, this installation plan has been developed.

II. Preparation Basis

1. “Code for Construction and Acceptance of Crane Equipment Installation Projects” (GB50278-2010)
2. “General Code for Construction and Acceptance of Mechanical Equipment Installation Projects” (GB50231-2009)
3. “Code for Construction and Acceptance of Steel Structures” (GB50205-2001)
4. Installation drawings and technical documents provided by the equipment manufacturer
5. On-site measurement data and site conditions

III. Main Equipment Parameters

Parameter items	Numerical
Rated lifting capacity	10T
Span	20m
Overhang	5.2 meters left/6.5 meters right
Lifting height	10m
Lifting speed	8m/min
Running speed	87m/min

IV. Pre-Installation Preparations

(I) Technical Preparations

1. Family familiarize yourself with the installation drawings and clearly identify the location and installation orientation of the conductive side of the trolley.
2. Verify the track installation quality:
   • Level difference between tracks on the same side ≤ 2mm
   • Level difference between two tracks ≤ 8mm
   • Difference between track centers ≤ 2mm
   • Track gauge tolerance ≤ 5mm

(II) Site Preparations

1. Use a 50T mobile crane as the main crane and dock it at the designated installation site.
2. Clean the installation area, establish a vehicle access route and work space.
3. Prepare ground anchors and draw a schematic diagram to calibrate the anchor point locations.

(III) Material Acceptance

1. Check the parts according to the delivery list, checking specifications and quantities.
2. Inspect and repair any deformation or damage to major components.
3. Prepare 12mm guy rope, jacks, wrenches, and other tools.

V. Installation Process

(I) Component Unloading

1. Unload the traveling crossbeam, outriggers, main beam, and other components in order.
2. Avoid stacking them tightly. Place the lower crossbeam directly on the designated track location.

(II) Outrigger Installation

1. Assemble the end beam and outriggers, connecting them according to the numbering and ensuring that the bolt holes align.
2. Secure the upper ends of the outriggers with 20# channel steel.
3. Lift the outrigger assembly (approximately 10 tons per unit) onto the track, locking the bottom wheels.
4. Install the outriggers symmetrically on both sides and secure them with 3′ steel wire ropes.

(III) Main Beam Lifting

1. Position a 50T truck crane directly in front of the main beam.
2. After securing the lashings, conduct a test lift. Lift to a height of 100-200mm and hover for 5-10 minutes to check balance and braking.
3. After optimal adjustment, hoist the components above the outriggers and secure them securely.

(IV) Accessory Installation

1. Lift the trolley, rain cover, ladder platform, and other components.
2. Install the electrical system, railings, and other miscellaneous components.
3. Assemble the control cab, platform, and other welded components.

VI. Quality Assurance Measures

1. Track installation uses paired inclined irons for adjustment, maintaining levelness within 5mm.
2. Maintain a 3-5mm gap between the electric hoist wheel and the track.
3. Bolt hole spacing on the main beam connection surface is measured and adjusted in real time.
4. Personnel working at height must wear a safety belt.

VII. Safety Assurance Measures

1. Pre-lifting drills are conducted, with standardized command language.
2. Standing below the lifting area is strictly prohibited.
3. Outrigger verticality is corrected using windlasses.
4. Provision of temporary ladders and guardrails is required.

VIII. Construction Equipment Plan

Machine name	Specifications	Quantity
Truck crane	50T	1 unit
Wire rope	φ15.5mm	Several
Jack	10T	2 unit
Theodolite	J2	1 unit

IX. Workforce Planning

Type of work	Number of people	Responsibilities
Crane Operator	4	Directing lifting operations
Installer	6	Component assembly and fastening
Electrician	2	Electrical system installation and commissioning
Safety Officer	1	On-site safety supervision

X. Trial operation and acceptance

1. No-load test: Checks the flexibility of the operating mechanism.
2. Dynamic load test: Tests at 1.1 times the rated load.
3. Static load test: Tests at 1.25 times the rated load.
4. Completes handover and acceptance procedures.
